Intel 6200 connection issues on G73jh

I thought i'd start a thread on this because everywhere ive looked for answers so far has not yielded success. Im not up to scratch when it come to networks so im going to lay out everything i think will help you to help me.

I have a G73jh with stock bios.

I have a Belkin N wireless router (F5D8236-4v1) with Firmware Version 1.00.02 (Jul 31 2008 22:32:30).

Router settings are as follows:




I recently had an intel 6200 wireless card installed and have been having issues. I cannot connect (consistently) at higher than 150Mbs and reception stays at 4 bars most of the time. The standard Atheros card that came with the system never had an issue with reception when i was this close to the router and was always at 5 bars. I bought this card for the increase reception at a greater distance, not less.

I have upgraded the driver to the latest version (13.3.0.24), and have the following settings on the adapter:

802.11n Channel Width for band 2.4: Auto
802.11n Channel Width for band 5.2: Auto
802.11n Mode: Enabled
Ad Hoc Channel 802.11b/g: 11
Ad Hoc QoS Mode: WMM Enabled
Fat Channel Intolerant: Disabled
Mixed Mode Protection: CTS-to-self Enabled
Roaming Aggressiveness: Medium
Transmit Power: Highest
Wireless Mode: 802.11a/b/g

I have the "Use Intel Connection Settings" enabled.

Chastity recently advised me that I "need WMM enabled plus WPA2-AES to get N speeds above 150 on the router." On my wireless properties, i have "WPA2 -Personal" enabled and encryption type is set to "AES". I changed the adapter settings above to WMM enabled (its defaulted to disabled).

Why do i seem to be getting a worse signal that with the old atheros card? Would the stock bios have anything to do with it?


This has been bugging me for a few days now, so any help would be great.

 

I see the problem already: you have TKIP enabled, and WPA enabled. USE WPA2-AES ONLY.

1) Having WPA enabled disables speeds above 150. WPA2+AES Only for 300mbit.

2) Having WPA+TKIP enabled or WPA2+TKIP is like having a super deadbolt on the front door, and only a flimsy chainlock on the back door.

 

Thanks Chastity! Now, if only i didnt brick my laptop trying to flash to 211!

 

Finally got my laptop back and took your advice and changed the router authentication setting to WPA2-PSK and the encryption technique to AES and....no difference!



This is annoying me now to no end, because this lower signal is noticeably affecting my download speeds. Does my router just hate this card? Please help!

 

Now that WPA2 AES Only is enabled, now you need to make sure WMM is enabled on the router too. Intel drivers require it for N speeds as well.

 

It shouldn't affect your downloadspeed at all. As long as the card states you got 150Mbit/s, you have 150Mbit/s. If there are signal problems, then it drops to 72Mbit/s or lower.

The main problem is that you use the 2,4GHz network for Wireless, this sucks big time. Bluetooth, Wireless keyboard/mouse, microwave, wireless cameras, .... all use the 2,4GHz band. They all make the signal worse and produce a lot of "noise" on the channels.
Could you install inssider and make a screenshot of it while running?
That tool will show you all WIFI devices near you and the channels they use.

The second thing is the card, I guess it's from Ebay and it's an "Engineering Sample"? They are sadly not as good as the real ones (I also own one)
And last but not least, what do you mean by "affecting my download speeds"? How fast are they and what should they be?

Oh and one more thing, 802.11N is since 2009 or even 2010 a standard, your Belking firmware is from 2008, so it's not really optimized for true 802.11n

Hey guys,
I have a quick question regarding the Intel 6200 card.
I want to upgrade the wireless card in my G73JH to either a 6200 or 6300. I bought a Linksys E3000 router and my internet connection is a standard high-speed 7.5Mbps.

Will I see any difference between the Intel 6200 and 6300 or am I better to just stick to the 6200 and not pay extra for features I won't use on the 6300?

 

you will not see a difference between the 6200 and 6300. The only time you will is if you get a router that supports 450 mbps and so far those are few and far between and very expensive.

people might claim the 3rd antenna will give you better reception, but that is very unlikely. The three antenna wires all run pretty much next to each other, so in order for 3 antennas to be better than two they would have to run in different places.

PS. I have now owned a laptop with the 6300 and one with the 6200 and I get the exact same reception in the same places with both. I use a DGL-4500 router.

 

Thanks a lot for the quick response.
I will order a 6200.

 

Bump. I am having thesame issues. Only I'm getting not 150 but only 72. Laptop is sitting right next to the router. Are there any settings I can change to help performance??
