I have an Intel 3945ABG in my e1505 and the thing works PERFECT with my Netgear Wireless-G router at home. I have also used it at a friend's place with a Wireless-G router and it worked fine. However, when I take my laptop to my bro-in-law's, it won't connect to his Linksys Wireless-B router. I know the router works fine because he can get his laptop to work just fine (im not sure what wireless card it has but it isnt a 3945). And his PlayStation 2 wireless adapter also works just fine with the router. There isn't any kind of encryption for the router...its open. And there aren't any 2.4Ghz phones in the house. Only 5.8GHz. I have also updated my card with the latest drivers. That should clear up any technicalities.

So here is what happens when I try to connect:
The router is found easily by both the Intel wireless program and the normal Windows Wireless utility. And to add on to that, both of them find it with full signal strength. But when i click on the connect button, one of two things happen. Either A) a connection will not be made and it wont say why; or B) It will make a connection and establish an IP address but as soon as I try to do anything on the internet the connection will be lost.

The only thing that I can see which is probably the root of the problem is that at some point during the connection phase or right after I make a connection the signal strength jumps from "excellent" to "poor" for no reason. Also, when i view the advanced statistics in the Intel wireless utility, the percent of missed beacons and signal errors is extremely high...somewhere in the 50 to 90 range. But like i said, the signal strength is rated as High 95% of the time. Does anyone know what the heck is going on and what I can do?
