Ridiculously Slow/Flaky Wireless

[Amorphous]

OS: Windows 7
System: Sony VAIO SR
Router: Linksys WRT54G
Wireless adapter: Intel WiFi Link 5100 AGN

Around the house, my wireless connection is ridiculously slow where on previous occasions it was always fast. I have another laptop I'm running side-by-side with the my VAIO and its wireless performance is flawless, so I'm confident the router isn't the issue. My VAIO reports the signal quality at full bars, but the speed is usually only at 1 or 2 Mbps, whereas my other laptop always holds at 54 Mbps.

The connection itself is flaky. I get knocked off every 5-10 minutes. The only time there's any stability is if I'm 5-10 feet away from the router.

Any suggestions? Thanks.

Hi Amorphous, welcome to the forums.

I would personally look to resetting your router, there could be certain addresses that might not be being read correctly by 7. I have had similar issues with connectivity on other peoples machines & a router reboot has solved all of them.

   Note

After resetting your router, it can take up to 2 minutes to be fully internet capable

Hope this helps

Thanks! Unfortunately, resetting my router did nothing. I thought I solved the problem last night by editing my power plan. It seems that my wireless adapter was running on a power saving mode. After an adjustment, I thought I was in the clear when my connection was reporting speeds of 36 to 54 Mbps. However, it seems I'm back to square one this morning with an abysmal 1 to 2 Mbps. I really haven't a clue what's going on.

IPv6 support off? what anti virus/firewall? 32 bit or 64?

[Amorphous]

I'm not using a firewall or anti-virus application. It's 64-bit. The status window reports that IPv6 connectivity has "no Internet access." I don't believe I've turned off IPv6 support.

 

[zigzag3143]

IPv6 probably isnt the problem but its not being used so you might as well turn it off.

Not even the win 7 firewall?

 

[Amorphous]

I disabled Windows Firewall earlier while trying to pinpoint the problem. I turned off IPv6 as suggested.

 

[zigzag3143]

Has this worked in a different OS? Could you have a hardware problem with the wifi card? Has the computer been opened, or dropped?

 

[Amorphous]

It has not been opened or dropped. It's brand new. I'm not sure if the problem occurred previously because I upgraded to 7 instantly upon receiving it. I think I'll try reinstalling Vista to see what will happen. Thanks for your help.

I'm having similar problems.

I have a Dell Latitude 1520 with a Dell 1505 wireless-N mini card.

I'm getting 1mbps or less (more often than not, less) with an 802.11n connection that is no more than 15ft from the access point.

-Have reset the router (many times)
-Windows firewall is off
-Powersaving setting set to max wireless (i.e. no powersaving in regards to the wireless)
-Have tried Windows provided wireless drivers (even the ones updated via Windows update)
-Have tried Dell's Vista drivers
-Card operates at 50+mbps with XP
-Wired connection works fine

This seems to be a recent problem (1 or 2 months). I've been using Win7 since sometime is very early spring and while I never actually checked the speed my wireless card was getting, I also never noticed it being a problem until recently.

Anyone have any idea?

side note: the really sad part here is that the card works a LOT faster in Linux and there isn't even a Linux drivers for the card. :huh:

I also had a problem with slow internet through wireless here is how I resolved it !

Although the link is in reference to file copy issues it resolved my slow wireless connection to the interweb

Even if it is a myth, I see no harm in trying this particular method. Thanks.

Router is a Linksys WRT330N. While am I getting slow Internet connection, Modem and ISP are irrelevant as the problem occurs with file transfers between my other Win7 desktop. Thanks for the reply.

I am using a Linsys WRT56G router and a Dlink card, I am still having some issues as it happens, but it appears to be on port 80 only. I think it maybe my virus/network checker. Looks like I am going to try a fresh install to see if that cures the problem.

Hi, I have the same problem as well with Windows 7 on my Asus R2E.
The strange thing is, that after installing windows speed was OK, but on the other day it decreased drastically. I'm not sure what happened, maybe some update has been installed, or something.

P.s. my router is D-link DIR-655

And after dissabling "Remote Differential Compression" it's back on full speed

 

[logicearth]

That would be an incorrect assessment.

 

[Juozas]

That would be an incorrect assessment.

Today after restart, it's back on very slow speed (like 8 Kb/s), and after reenabling RDC, speed goes to normal, but only until next restart...
So yes, it does not matter if RDC is on, or off.

Same effect does disconnecting and reconnecting back to wireless network.

I have encountered the exact issue. Running Windows 7, getting full bars and am within ten feet of the router, speeds at 54mbps, but randomly drop down to 1mbps. No rhyme or reason to when it happens or how long it stays this way. I have seen other Windows 7 users describing the same symptoms, but have found no effective fixes.
