Laptop can't connect from my bedroom, but can

Hi all,
I'm trying to resolve an ongoing problem I've been having with my laptop connecting to my wireless router. Throughout much of my house, my laptop does not have any trouble connecting to the router wirelessly. Whenever I go into my bedroom, however, I lose the connection and am unable to reconnect. I set up a small office in my bedroom, so I'd like to be able to use my laptop there, and running a cable up there isn't an option.

Here's the thing: My wife's laptop work just fine in the bedroom, and pretty much anywhere else in the house. So does her iPhone. And my laptop seems to connect well to just about any hot spot elsewhere.

When I'm in my bedroom with my laptop, checking with Network Stumbler, I see that the signal to my router is quite strong -- not that much different from when I'm only a few feet away from the router. There are several other wireless access points that my card and Network Stumbler pick up, but my router is the strongest, even in my bedroom. Also, I'm using a different channel than any of the other access points in range (channel 2).

We have two different set wireless telephones in the house, including one in the bedroom. There are no wireless phone bases in the room with the router.

Here's my home networking setup:
I have a D-Link DI-524 Wireless router. It's hard wired to our media PC and a network storage device. Connecting wirelessly to the router are a Wii (a few feet from the router, but its usually off when I'm using my laptop), my wife's laptop (Thinkpad T42), her iPhone, and my laptop (Thinkpad T400).

I've been doing research, but can't find any good leads on how to further diagnose the problem, what else to try, or how to resolve the issue. Any suggestions would be much appreciated!

It's odd that yours doesn't work properly in the bedroom and your wife's does. The only thing that pops into my mind with regard to that specifically is it may be a issue with the wireless interface in your laptop.

We have two different set wireless telephones in the house, including one in the bedroom. There are no wireless phone bases in the room with the router.

You might want to try moving the handset in the bedroom to another location or for testing purposes, just unplug it completely so it's off and not broadcasting wirelessly and see if that changes anything.

The first thing that popped into my mind as I started reading your post was interference, which a cordless phone could create.

Thanks for the reply and the suggestions. It's possible that the phone was interfering with the router signal, but if that was the case then why didn't my wife's laptop or iPhone have problems? Strange.

Regardless, I received the suggestion to switch to channel 1, 6, or 11, as apparently those are the only channels of the 11 that "won't get interference". I don't know the details, but I tried it out. I switched the router's setting for channel from "auto-select" and specifically set it to channel 11. I used Network Stumbler to find out which channel among 1, 6 and 11 had the least number of other access points in range, and it turned out to be 11.

Anyway, after doing that and reconnecting, it solved the problem. My wireless phone is still plugged in and all devices work from the bedroom and elsewhere, so all is good!
