Apparently my wireless router can't handle my Intel 6250?

Ever since I got my replacement laptop with an Intel wireless card, I've been having issues with my router disconnecting when I'm downloading files. I had a Dell Wireless 1520 in my original and it never gave me the following issue.

If I am downloading a large file and speeds go up to 500 or 600 kb/s, every single device that's connected to my router gets disconnected (even my cell phone) and can't reconnect for about 1 minute.

I remember this one time my friend came over and I believe he has the intel 5300 in his 1640 and it was doing the same thing. At that time I thought it was my router acting up. But after performing a few tests, it only happens when I download large files (like the video driver for my laptop). I have a Linksys WRT 160nv3 with a dd-wrt custom firmware.

Anyone know how I can fix this? I tried using the Dell drivers and I tried using the newest drivers from Intel's website but neither fixed the issue.

 

Have you tried using the standard firmware?

 

Yes, that's what i originally had and tried a custom firmware to see if that fixed the issue. Sadly, it didn't. I may end up buying a new router. Possibly the Linksys E3000

 

Does the router get reset? Check the router uptime after it reconnects (ddwrt status page should show this, try 192.168.1.1). Do you lose internet connection or router connection? Any modem logs (try 192.168.100.1)?

 

If Tomato is available for your router you should give that a try.

If you do decide to replace your router consider the Netgear WNDR 3700. I recently replaced all my routers and access points in my house and went with the Netgear instead of the Linksys E3000.

 

What happens is, all the computers get disconnected. The wireless network is visible in the networks I can connect to, but if I try to connect, it trys to connect and it fails to connect.

And before dishing out more money on a router, i'll try tomato if it's supported.

I'm considering this. Don't want to spend too much rite now.. this is probably the highest im willing to pay rite now.

 

It doesn't sound like it is related to your problem, but I was having trouble with losing connection from my laptop to my router until I upgraded the drivers for the Intel 6250.

 

I also have the 6250 on mine (and I had a 5300 pre-replacement) and they both run just fine on my router. I have the TRENDnet TEW-639GR router, which happens to be on sale at newegg for only $60 and free shipping. Newegg.com - TRENDnet TEW-639GR 802.11b/g/n Wireless Gigabit Router up to 300Mbps

That said, you really should update your wireless drivers before you buy any new hardware. Here's a link to the newest drivers, which just came out a few days ago.  Intel® PROSet/Wireless WiMAX Connection Utility for Windows 7 64-Bit*

 

Hey, thanks for the link. I did have those drivers on my laptop. I took my laptop over to my friend's house and the same thing happened with his router. He has the Linksys WRT54g so I think it's related to linksys. So I bought the Netgear wndr3300 (normally 100 bucks at best buy but I got it on sale for 79) and it doesn't drop the connections anymore.

 

You already bought a new router, my first thought was that your linksys might have been over-heating from having to deal with the extra stress of dealing with the prolonged activity of large file transfers.

 

I used to always buy Linksys because I thought 'they're made by Cicso, so they must be good', but honestly, they're really some of the buggiest consumer grade routers I've ever used. Glad to hear your new router is working fine.

 

It actually started to disconnect when i was just browsing the web with no file downloads. But either way, I don't think i'll buy linksys again.

 

Try disabling IPv6 on the computer and if that doesn't fix it try tinkering around with the security settings. I have a Linksys router and had problems with it, disabled IPv6 and it worked perfect. Now with my current laptop it had problems staying connected and changing the wireless security settings fixed that. Don't know why or how any of this worked...but it did. YMMV.

 

He's already fixed his problem but I wanted to add that IPv6 can't be disabled on Windows 7 (and perhaps Vista) - it's been so fully integrated now that it's always there even if you turn off all the IPv6 bindings and other services. This according to a Microsoft employee anyway, turn it all off and you can still run "ping ::1" for example. Basically I've also heard it's bad to do and accomplishes nothing, so don't even go that route...
