Slow Connection: Vista the cause?

Hi,

I have a new wireless router (Linksys), however internet browsing is extremely slow (wireless & wired via the wireless router). When i say SLOW i mean 20-30 seconds to load a page. Speed test don't run half the time and when they do it will be on par to 56k. Search results via google seems fast. I have DSL and usually get 4800 kbs on average.

Everything is fine, if I do not use my ISP modem.

I have tried everything possible and on 2 laptops. Both are running Vista with one having a fresh install.

I have tired manually putting DNS server, updated the firmware. Adjusting the MTU size. Flush DNS cache, release/renew IP about 20 times and have turned the modem & router off when I change any settings. Tried also diable TCP IP V6 and differenct cables.

I suspect Vista is the culprit and have read many similar issues not relating to specific brand of router.

Could anyone offer anyhelp?

I don't really care if i have wireless or wired as long as I can use the wireless router as I have more then one computer.

 

are you sure its not just internet traffic and the connection you have. Cable internet gets slow because its one giant connection shared through mutliple houses. To test your internet connection plug your modem lan connection directly to your pc that will show you your real speed. I think it could be just your linksys router needs a firmware update or configured properly. get back to me

 

This part really confused me.
Does it mean that you own 2 modems, one that you got from the ISP, and one that you got elsewhere, or did you mean that connection works fine, say, at your friends house.

The way to solve problems like this is to start step by step:
Test modem. Connect one laptop directly to the modem. Speed is OK means modem is OK. If modem is OK, then the problem is the router.

Although you read of many similar issues with Vista, I can assure you that those problems happen on only a small percentage of the total computers using Vista. Having said that, if both your laptops exhibit the same problem, then it's most likely not a Vista issue.

To chinmonkie:
1- Cable connections don't get slow to the point of beign just as slow as a 56k, no matter how many people use the same provider.
2- JBlue said he is using DSL.

 

I mis-typed. When I use ONLY my ISP modem. I am blazing fast!

However using the wireless router. It is just tooo slow. I am CONNECDTED and search results in Google seem ok but once I goto an actual page it is SLOW.

Once again. This happens when I use wireless and cable to the wireless router. I am only using one laptop at a time and even if both laptops are connected seems should not be this slow.

I have also tried to rename the wireless router page to 192.168.2.1 as I thought maybe there was a conflict.

I am at a lost. I ahve done the basic trouble shooting 101. I don't know what is going on.

I should state both laptop is using Vista.

 

Look, directly into the modem is fast, wired or not through the router is slow. How can you even think about blaming vista?

The problem is the router, exchange for a Dlink if it's still possible.

 

I have tried 2 different routers and it is the same thing. If u do a search on google. This seems to be more then rare occurance. Not brand (router) specific but Vista. Many faild attemps from the things I ahve stated. More have stated something about the new IP v6 driver that Vista uses is faulty.. but I have tried that.

I thought maybe someone on this forum have the same problem. I will state the this very same router works fine in XP.

 

Sounds like a configuration error to me.

 

Your configuration should be ISP > MODEM > ROUTER > PC.

You need the Modem with a DSL ISP. Your modem may or may not include a built-in router. You can usually plug directly into the ISP Modem; however, you can also plug a router into the ISP Modem. Then you can either plug your PC into the router or access the router wirelessly (if it is a wireless router). You actually want a router after the ISP Modem to provide you with DHCP and NAT, not to mention the network sharing that insinuates.

I cannot see how DSL would ever work without the ISP Modem in the path.

 

AKA..

Yes my Modem is from my ISP. My wireless router is Linksys. I have basically done all standard trouble shooting 101 plus: flushing DNS cache, IP stack in cmd. Manual DNS, rename ip of router config, disabled TCPiP V6..yada yada yadaa...

I am on DSL so in my router config. I use PPPoE.

I should of been more clear. phone line > ISP Modem > Wireless router > Laptop. Once again wired and wirless nets the same results. I am connected successfully. Searches in google have fast results but page loading or modem speed testing is hte problem.

Configuration error? like?

 

You left the ISP Modem configuration alone? Did you do any configuration to the LinkSys router?

And to be clear:

• When you plug your PC directly into the Modem it OK
• When you plug into the router it is slow
• When you access wirelessly via the router it is slow

If the answers to all those are "Yes", then hard reset the LinkSys Router and retest. If it is still slow the router is the problem. I'm not quite sure why you disabled IPv6 in Vista, either.

 

Yes on:

And to be clear:
When you plug your PC directly into the Modem it OK
When you plug into the router it is slow
When you access wirelessly via the router it is slow

I have tried HARD reset on both wireless router and modem.

regarding the IP v6.. i have searched on the net and there seems to be a known error with the version of that driver. By default it uses v6 but v4 is also instaleld

 

I recommend leaving IPv6 alone in Vista, unless you are trying to set up your own IPv6 network.

In any case, you appear to have answered your own question. The same PC works well without the router and somehow less well with the router. Therefore, the issue is either with the router or with the configuration of the network on the PC to accommodate the router.

Your ISP Modem is not a Modem+Router is it? Double NAT or double DHCP can cause some problems.

Did I read that correct: That the router works well with an XP PC?

Also, 32-bit or 64-bit Vista?

I'm leaning towards a NIC driver issue on the Vista PC.

 

AKA.. thx for the help. I reverted back to old settings (IPv6).

My modem is a regular speedstreakm modem (no router).

Yes modem is ok on XP. Default Vista 32 settings. on 2 diff laptops. Fujistu and new T61 w/ all updates

I found someone on craiglist selling a new wireless modem for $25 bucks. So forget this Linksys.

Too much trouble for what it's worth.

 

Just doublecheking, did you mean you found a new wireless router, or did you really mean modem? A modem with wireless built in would be the easiest way to go, but not many of those around, and are usually expensive.

And yes, just like Aka said, don't mess with IPv6.

Basically, with all the info you gave us we can conclude some things:
1- Modem is perfectly fine.
2- The computers are not trying to use the same IP, since you said the problem happens even with only one computer connected.
3- No 2.4GHz interference, since problem also happens when hooked up.
4- I'm almost 100% positive everything is fine with the computers, else they would get slow connection even when hooked up directly to the modem.

So the only thing left is the router. I'm not saying that the two you tried are broken, but if they were both linksys, it may be a configuration error(not on the computer, but on the router settings, although you said you set it to PPPoE, so it means you had an idea of what you were doing).

Just in case, leave TCPIPv6 like this:

and TCPIPv4 like this:


Once on the router, the only things that should be changed are connection type to PPPoE, and sometimes switch the wireless feature on. DHCP server must be on, but this is already the case on most routers. After you get it working, the maybe add encryption.

Question:
What's you ISP?

 

daniel_g,

My modem is a standard speedstream modem w/o router or wireless capabilities. My wireless router is a Linksys WRT54GR.

I have checked my settings (TCPv4/6) and they are back to default (same as pic).

DHCP is On and I do use encryption WPA-Personal/TKIP.

I can understand if I am not connected. However I verify in the config page (192.168.1.1. I also get search results just fine in google. It is the surfing around that gives me the headaches.

My ISP is Teksavvy. In Canada.

 

Can you open command prompt, and type 'tracert www.yahoo.com' without the quotes?
Do it both, while connected to the router, and connected directly to the modem. I'm curious to see what you get.

I'm also looking at the possibility that the cable between modem and router is bad. Have you tried a different cable? Of course if you used that same cable between computer and modem, then that's not the problem.

 

That is a fairly common router, which should work out of the box (or after a hard reset) in most cases. It could be that you've simply got a bad one.

 

I ended up buying a new DLINK router for $25... NO idea why linksys did not work but I don't care.

ths for the help.

 

Jblue, I never heard of that ISP provider before where are you located ?
I just use rogers. and i am glad you got your problem fixed

 

Glad you got it working. Having a router in the path is a beeter solution for many reasons.
