Problem with Intel WiFi Link 5100 AGN Can not exceed 65 Mbps in speed

Then I wonder if Lenovo 3000 N500 4233 series supports N network with the following network card, Intel WiFi Link 5100 AGN.

The techniques for Lenovo and Intel says YES.
But in reality, I can not over 65 Mbps, though I should have at least 120-130 Mbits as techniques for Lenovo and Intel says.

When I linked up with Rauter with N, so I got a speed of about 65 Mbps, but far away from the
speed of 100-130 Mbit/s +.

I have spoken to Lenovo and received a reply to update drivers on all that goes too uppdate and see if it works.

For if I have 65 then I am on N linkage because the G only goes up to 54 Mbit/s.

So what do you do?

Someone who knows what to do?
Could it have something to do with Cpun which is a Dual Core Pentium 2Ghz with 3GB
framework and Vista Basic. Can your computer to be too weak for such high speeds?

there is someone who has a similar computer or weaker model and run with
Intel WiFi Link 5100 GLUME and speeds over 100 Mbit / s

I bought the computer for exactly 7 days ago at Media Markt in Malmö - Sweden.

What can I do to have 130 Mbit plus / s, etc.
I have updated and installed everything that goes to update on the computer but still no higher speed?

Has also updated Rauter, etc. but no luck!

All help is welcome!

 

From what you're describing, it sound like your Router's Mode setting is set to Wireless G Only, or if it's a dual-band N router, A or G.

The AGN Adapter will adjust itself to whatever the incoming wireless frequency/data rate is. It adjusts to whatever the lowest supported device setting is. If your Router is set to a Wireless band of G, then your adapter will connect at G speeds only.

You need to access your Router's Admin panel, check your Mode setting and change it to Mixed or Wireless N only. Since you have 2 N devices, start with N only first. For your Band setting offset the frequency so you can avoid interference from similar frequencies on local devices.

Make sure you also set and enable your SSID to a unique setting so you connect to your own network and not some bozo across the street.

On your Adapter, access the Properties window and then go through the various settings to match them with your Router's output settings as well. If you're not sure how to do it, concentrate on the Router setup.

 

thanks for the quick response!

I have only N network and I have another laptop (LG) who also has N. It runs in 130+ Mbit / s

While my max out @ 65 Mbit/s.

Have tested, for example, with D-Link DIR-655, Extreme N Wireless but with out success.

I tried to just run N but then my Lenovo N500 got disconected and no contact while LG received.
I tried to just run Lenovon in N against Rauter no success!

I have WPA2-PSK What is what Intel Recommended. But it was not better for it!

when I installed and tested the card so I got 130 + Mbits but only for a short while about 30 sec!

 

I wanted to say almost the same as CyberVisions, I'd second everything he said.

I have some problems to understand what you are trying to say in your last post Hunter. But I think it's a router problem. Personally I had just bad experiences with D-Link routers, though my usage is somewhat advanced (I run some fixed installed wifi links with point to point antennas - weren't stable and compatible enough in the long run for me).

At first you should update your router frimware. The D-Link support site is here:
http://support.d-link.com/chooseCountry.asp

Also update your Intel 5100 driver to the latest version, even though my first guess is it's just the router.

 

Read the thread listed below, it might help you squeeze a little more performance out of 802.11n. Also, know this is not necessarily a Lenovo issue, but more of what’s expected with 802.11n and consumer-class APs.


802.11n performance (5100 vs 5300)

Thank you

Hmm, I have updated both the computer and D-Link but also tested with a Netgear, the same problem.

From the start, would i not have more than 54 Mbit but after that updated everything possible, it whent up to 65 Mbits. But still it's far away from 100+ Mbts

I have tried to set as the D-like, Neatgear and Intel recommendations. Without any luck.

What Rauter would you recommend?

 

Have you checked your 802.11N channel width setting in your computer? Try changing the setting to 'auto'. It worked for me.

 

yepp I try that but no luck.

 

Read my thread on the 5100/5300. I had to adjust a variety of settings to exceed 65Mbps on my setup (x200 Tablet w/ 5100, D-Link DIR-655).

To start you should do the following:

1. Set your router to 802.11N only
2. Disable Encryption (we will set up WPA2 after it is working properly)
3. Set channel width to 40MHz (or automatic if this is not an option)
4. Open up device manager on your computer
5. Right click on the Intel 5100 and select properties
6. Under the advanced tab set "802.11N channel width for 2.4GHz" to Auto
7. You should now be connecting at full 802.11N speeds

It may only report as 130mbps in Task manager, but if you look at your routers wireless client list you should see yourself at 270 or 300 mbps.

Once you get this working you can set your router to WPA2 encryption, and 802.11 BGN if you want.

 

Thanks I will try this!

 

Thanks for the help i get!

Cover the test and still I dont make it work. However Program Access Connection show me for the first time 130 Mbit/s.

The problem is that both Windows status of network, still shows only 65 Mbit/s equally so does the program Access Connection status.

When I test the speed of transferring 8 Gb large file between 2 computers then it show only 65 Mbit!

What now?

 

Is it possible that it has to do with Cpun? Becouse of that, i can't get higher speed then 65Mbit/s.
For most people, how has this network card, has one of the Core 2 Duo cpuer. I have only Core Duo Pentium processor, and no centrino 2 platform.
Could it simply be that the design of the system can not pass the higher speed.

Does anyone have the same laptop as I Lenovo 3000 N500 product series 4233-39 or or equivalent computer parts and has worked to get higher speed than the 120 + Mbit/s on the laptop?

Anyone?

In the official document and brochure it says that it will clear N.
The information the seller received by Lenovo was that it has N support!
But inofficeiellt (from a few engineers from Lenovo) dual response.
That it can and that it can not do N support. Without the N is just G.
Intel says that it support N but is upp to the manufacturer to make it work with the rest of computer.

What is strange is that I have a number of adjustment possibilities that I can do with N. I can also
both activate and diaktivera N standard on the computer.

It will be to call Lenovo support again fore the 8 times to try to get 1 correct answer
about what really gowing on with N on Intel WiFi Link 5100 AGN.

 

AnyOne any info or tips??

 

Your CPU does in no possible way affect the link that is established between your WiFi card and the router. If nothing helps you may have better luck with an Intel 5300. It uses 3 antennas and it can use them to multiplex data, so it can deliver higher transfer rates and more stable links.

 

I have a Gateway P-7805u FX which has a 5100 wifi card in it, it just came out this week. I also have a Dir-655 I can only connect at 65mbps also. I have 4 older FX's that all connect at 130mbps, maybe the 5100 is just not that get of a card, I ordered a 5300, and will get it on Thursday this week. The 5300 has a 3 antenna connection, I think my laptop only has two antennas, I guess I will try using two of the connections on the 5300, we should not have to go through major tweaking to get a n card to handle n speeds. Does anyone have any thoughts on this?

 

I also have the 5100 and DIR-655, and the reason why this fails is quite rational. Read this sticky on the D-Link forums. It originally said that NO INTEL adapters could achieve 300 mbps (I PM'ed the mod and he adjusted to say "Not all Intel adapters"). My thread on this site should also be helpful to you.

The key is the ability to bond at 40MHz channel width at 2.4GHz. The Intel 5100 adapter (and probably the 5300/5350 as well) by default operate in 20MHz mode for 2.4GHz and 20/40 auto for 5 GHz. This is because 40MHz width on a 2.4GHz 802.11N network is apparently destructive to other 2.4GHz networks (including your neighbors Wi-Fi), therefore Intel (and the DIR-655) defaults to 20MHz only.

Therefore, you can either adjust the settings on your router (properly configured it should appear as 150mbps in task manger, 300mbps in your D-Link wireless clients list, and you should be able to transfer files from a Gigabit ethernet host at ≈110mbps). Or, you can buy a true dual band (2.4/5GHz) router as the Intel 5100 is set to 40MHz by default for 5GHz 802.11N connections.

 

I understand what your saying, but why would my other Gateway FX's listed in my signature connect at a faster rate, they have intel cards in them too, i believe it is the intel wifi 4965?

 

FWIW, the 4965s have more antennas than the 5100s—see http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3356&p=6 for details.

 

I can confirm this is also the case for the 5300s.

 

I will look tonight at both laptops, maybe the newer FX only has two antennas, I ordered a 5300 hoping to fix this, we will see, even if I hookup 2 antennas to the 5300 it may work better, just luck I guess

 

Well, if that's true, I will send back my 5300

 

Why? All this is, is a default configuration setting? You can simply change it with a few mouse clicks. The 5300 still supports more antennas and special streams.

 

Ok, that is good, but if the 5300 has three antenna connections and my laptop has two antennas, how do I hook it up? Maybe there is a third antenna hiding , or will it still work with two antennas?

I checked, my laptop only has two antennas, will I still gain anything be switching out my 5100 for a 5300 only connecting two antennas to the 5300?

 

Very interesting reading. I got a lot out of the replies. thankx guys.

my set up is a Qosmio w/ 5100 GAN on a medium home and office network Xtreme N Gaming Router D-Link DGL-4500. I have plenty of mixed hard and Wi-Fi things so I do need A/G/N on the same router. Switching to N only is not an option for me (just for test at certain hrs of the day).

I also changed the 2.4 width to Auto and that took care of the change from 65mbps to 150Mbps and displayed as 270Mbps in router display. This qosmio is running Vista Ultimate x64 and reports as 150mbps and my older Alianware based PM965 w/ 4965AGN is reporting 270Mbps in XP Pro x64, but reports as 240 in Router. I guess this is normal from what I read here. Is this a Vista thing or just the 5100 in general? Cause I always remember XP reporting 270~300 in ?Wireless Connection status".

so I am ording the Intel N 5350AGN and it is coming w/ the 3 antennas so I have to rout them into my monitor. my question is, will the 5100AGN work w/ my friends PM945 based notebook or at leastin any of my old PM965 units w/ old 4965AGN cars in them?

So, by mixed band, does that mean I should be able to use multi A/G/N from router w/ mixed 2.4/5.8 in N mode? Cause my 4500 D-link only allows 1 or the other in mixed A/G/N mode.

 

The notion that the 5100 cannot exceed 65 mbps is simply not true. I am, as we speak running at 150 mbps on a Wi Link 5100 on my Vaio SR and my mother gets 300 mbps on her N connection at her home(she has a macbook pro, i think it has the 4950....). Eitherway, my routher is a linksys WRT160N v2. Don't forget that drat N speeds cannot be achieved with WEP or WPA, you MUST use WPA2 or the router will default to legacy speeds(g). So try changing your routers security settings or disabling security all together. Also disable frame bursting and make sure your wi fi adapters settings are not limiting your speeds.

 

Just got my X200 and noticed this issue. My T61 with the 4965 was happily connected at 130Mbps and the new 5100 in the X200 was not getting any higher than 65Mbps.

The trick was to set the 2.4ghz channel width (in the advanced properties of the wifi card from device manager) to "Auto" from "20Mhz." This instantly changed the speed to 130Mbps.

I will be getting an 5300 soon from ebay and will swap out the cards. Lets see if that has the same problem and if the X200 has the 3rd (currently unused) antenna in it or not.

 

I am curious of how the upgrade process goes. I am satisfied with the 5100 now, but I might upgrade to the 5350 in the future if WiMax ever pans out nationwide. However, this is dependent upon how complicated the upgrade is (i.e. I don't want to have to crack the bezel and wire in a third antenna myself).

 

jon, if I don't find a third antenna already in place and just hanging around not being used when I open up the X200, I'm not doing the upgrade. I'm not about to wire an antenna into the lid either!

 

The upgrade is as simple as plug and play. Just access your card however possable and remove it (some are screwed in, some have retainer clip or latch. The 5300 & 5350 are 3 wire capable but can run as 2 wire if you do not wish to add the 3rd atena. It will at the very best add better bandwidth, and is perfectly fine if in the home close to your router.

As far as adding the 3rd wire, it is as simple as removing the back of the monitor lid. Some can be removed w/o unplugging monitor or detaching. In any event, it is simply just looming a wire around the lid area and taping in place (new wire will or should come w/ sticky tape). Follow the color coding on link card.

furthermore, the 5100 may display 150 in Windows but it does report as 270~300 in router monitor. This was tru even when I installed the old 5100 into my old PM945 based notebook w/ XP x64.

 

Thanks very much for the info. Knowing that I may put in a 5350 in the future. I also think I see where the antennas would go in (there is a line in the top bezel that appears to be for servicing the antennas), but I'm still not sure if I would want to crack open the top cover if I don't have to.

 

I ran several w/o the 3rd wire. It doesn't have to be up in the bezel. It can by all means be loomed inside the base under keyboard. just try not to just cram it up in a bundle in one area, try to extend it out as long a run as you can around the interior of the case. The monitor is actually far easier to open by simple screws around the surround then to open the case of most notebooks. The monitor surround screws are often plugged w/ the little rubber buympers that face you as you look at the screen. As I said, you dont

Good luck! Hope this helps!

 

Lappie, so have you performed this upgrade on the X200 specifically?

 

Keep in mind if like lots of us gamers with xbox and PS3 as well as PSP, you will need mixed B for the PSP and G for the PS3 for example. Lots of things still commonly use B/G mixed.

 

I have the DIR-825 with the 5100. I'm took stuck at 65mbs. This router is dual banded. Any thoughts?

Edit:

I followed the 5 step thing and it worked! Going at 150mbs now. Thanks.

 

Are you actually getting 150mbits/sec of performance, or is it just reporting that you are connected at 150mbits/sec? If you do a file transfer on your internal network, what speed to you top out at? For this you'd either have to look at the network tab in the task manager, or just look at how fast Windows Vista (assuming you're running Vista) says the file transfer is going.

I have a Intel 5300 wifi card in my X200 laptop. The computer reports that it is connected at 300mbits/sec, but the actual performance never exceeds 65mbits/sec. Typical file transfer rates are about 5mbytes/sec. I have two different wifi access points set up. One is a Linksys WRT150N running DD-WRT firmware. It's a 2.4GHz only router, and I've done the work to set the 40Mhz channel to auto on both the router and the card. But, it's running a mixed G/N network, so I really don't expect great performance on that one.

My second AP is a Netgear 5Ghz-only wireless-n access point. It is 802.11n only, and 40Mhz wide channel is set to auto on both the AP and the card for the 5Ghz band. Wireless encryption is set to WPA-2 AES on the X200. The X200 connects and works, and while the reported connection speed is 300mbits/sec, the actual speed is only 65mbits/sec.

I realize that 300mbits/sec is just the theoretical max, but the actual max speed for wireless-n is roughly 100mbits/sec. And, when I connect other wireless-n devices to the Netgear AP (notably, a Netgear bridge and a Macbook Pro), I get approximately 90mbits/sec of performance.

 

It sounds like you have everything set up properly. However, it's possible that your particular router isn't that fast.

Also, what are you pulling your data from? If both are connected via wireless, then they will have to share the maximum available bandwidth (wireless is a "blocking" technology). If your other computer is connected via 100Mbps Ethernet, then the hardwired computer may SLOW DOWN the wireless computer. My setup includes an 802.11n client, and all other machines connected via Gigabit Ethernet.

On my D-Link DIR-655 I am able to realistically achieve 110mbps pulling and 80 mbps pushing data on my x200 Tablet. This is with a 2.4GHz router, WPA2 encryption, NO G clients, and an x200T with Intel 5100.

Detailed performance results are listed HERE.

 

Thanks for the response. I don't know what the 2.4Ghz router is capable of. I'm in an apartment building, and the 2.4Ghz band is very crowded. But, there aren't any other APs operating in the 5 Ghz band. The Netgear AP might have some sort of compatibility issue with the Intel wifi cards, but the AP itself is certainly capable of ~100mbit/sec performance, as I get approximately that when I connect to the Netgear AP using a Macbook Pro, and when I use a Netgear bridge. I just don't get that with the X200.

Right. I'll briefly describe my network layout. I have my server hardwired to a WRT150N (2.4Ghz wireless band) router. That router is also hardwired to my Netgear access point (5Ghz wireless band). The Netgear AP is wirelessly connected to a Netgear bridge in a different room, which connects to my desktop computer. Since the WRT150N AP has to serve 802.11G clients, I don't really expect to get good performance on that, but I think I should be able to get good performance on the Netgear AP.

The Netgear AP <-> Netgear Bridge connection is fast. I consistently get ~90mbps performance.

I've tested the X200 when pulling data off the server (meaning only 1 active wireless connection), and off the desktop (meaning 2 active connections). Strangely, the speed tops off at ~60mbps either way. You'd think if the Netgear AP couldn't handle speeds faster than 60mbps that I'd only get 30mbps when pulling data off the desktop.

The server I'm pulling data off of is connected via 100mbps ethernet, but that doesn't seem to be limiting me here. I have a wired network too, and I can pull data at ~90mbps on the wired network. And, I can pulled data at ~90mbps over the wireless network using wireless clients other than the X200.

My only theory at this point is just blaming Windows Vista. My server is Windows XP SP2, my desktop is Vista x32, and the X200 is Vista x64. I've had problems in the past getting good performance with XP <-> Vista x32 file transfers. But, in those instances I was using gigabit ethernet and speed was topping out at ~120mbps. Plus Vista SP1 fixed most of that problem. Is it possible there's some weird stuff going on in Vista x64 SP1 that is slowing me down? It doesn't seem likely, but I don't know what else would be going on.

 

I still think that your wired network may be limiting you in some way. It's possible that in the transition from wired to wireless you may be losing some possible performance. If you really need maximum network throughput (I doubt you really do), you may want to consider getting a GigE switch.

I wouldn't blame Vista. All of my tests were performed with Vista Business x64 SP1 on the x200T and my other clients were running either Windows 7 or XP SP3.

 

Vista says I'm connected at 150mbps. I don't know how to do a network file transfer. I used internet speed test and it now downloads at 7.5mbits.
http://www.speedtest.net/

Before that the fastest was 2.5mbits.

jonlumpkin, how do you check your computer connection speed on your router?

 

On a D-Link router you should be able to login to the router (usually 192.168.0.1) via a browser and view the client list.

1. Navigate to your router IP (default is 192.168.0.1)
2. Login
3. Click the Status Tab
4. Click Wireless
5. View Clients

Your ThinkPad should be listed by it's computer name. It should include SSID (I use both a private WPA2 and a guest WEP), MAC address, Local IP, Mode (should be 802.11N), Rate (I usually get 240-300 mbps depending on range), and signal strength (mine is often <50% according to the router so don't worry about this).

For future reference, the D-Link emulators can be a very valuable tool for taking a look at the firmware of ANY D-Link router. This can be helpful for seeing if the interface and features suit your needs BEFORE a purchase.

 

Need probably isn't the best term, but I do frequently move large files (~1 gigabyte) between my computers. It won't kill me to have the transfers take twice as long, but it's a little annoying. I also do a little bit of HD mpeg2 video streaming between my server and my X200 (my server is a media server with 4 TV tuners and 4TB worth of hard drives). 60mpbs is only about twice what I need for this to work at all. It seems to work OK for the most part, until I start fast forwarding or rewinding. It syncs up eventually, just not quite as quickly as I'd like.

I agree, it seems unlikely. But, prior to SP1, network transfers were quite slow, which is why I thought/think it's a possibility. It was especially bad, relative to WinXP, when I had the maximum frame size set at the standard 1500 bytes.

I can probably tell really easily by hardwiring my X200 to the network and seeing what kind of performance I get. I'll try that tonight.

By the way, do you know of any good (i.e. easy to use) network benchmarking tools? It seems like most of the people on here are concerned with the reported connection speed when what they really should be concerned about is their actual network performance.

 

Your setup is not too dis-similar to mine, although I only have about 2TB on my desktop/media server. So, I certainly understand your desire to achieve as fast a transfer as possible.

I would recommend you check out http://www.smallnetbuilder.com/ they seem to be much more concerned with actual throughput than reported speeds. You can either see if you can acquire some of the tools they use to benchmark routers, or you can ask in their forums, as you may get more appropriate advice.
