Internet Connection Stops Working on D-Link DI-824VUP Wireless Router

I am using the above mentioned router with three IBM laptops..two t41's and one R50.  Two of these laptops have the IBM A/B/G wireless card installed.  The other laptop has the Intel Centrino B card installed.

After a week of using the router, we have noticed that the Internet connection stops working after 30-60 minutes of use on the two machines that have the IBM wireless card.  The laptop will show a good wireless connection, but the Interet connection won't work.  Turning the power to the wirelss router off and then on restores the Internet connection.  So far, the laptop with the Intel card has not had the problem.



ICS is disabled on all machines, and the Comcast cable connection does not require a MAC address to to be provided.  I have carefully checked the SSID, etc.

How can I troubleshoot this problem?

If the wireless signal is being dropped and reconnected, without me noticing would this cause this?

By the way, how many wireless connections may I have with this router?

Thanks

jseverson,

This sounds an awful lot like you have either a) a bad router or b) electromagnetic interference (EMI) that is causing a sporadic problem with your internet connection. The router in question will support up to 4 connections, so you are well within the limits specified by the manufacturer.

You might want to check for things between the computers and the router that might cause interference, i.e. neon lights, refridgerators, AC units, etc. Move the computers a bit to see if that clears it up. If not, I'd see if I could exchange the router for another.

Check to make sure your wireless AP is on the same Channel as your computers.....I had a client recently that had the AP set for channel 10 and the computers set for Channel 11....sometimes they would connect and then they would loose their connection....
Just a shot in the dark....
Good Luck....

Regarding the wireless channel for the laptop computers being the same as the wireless rounter...I am not able to find any setting that shows what channel the IBM T41 computers wireless card is set to.  I don't see it in the IBM Access software, nor in Windows XP.  Where would I find this?

I tend to think that the router may be bad...when the Internet connection freezes up, the wireless connection still shows good.  An immediate attempt from the lapto to drop and reconnect the wireless connection will fail.  This is solved once the router is powered off and back on.
