I have a Linksys WRT160N wireless/wired router. Prior to last week, I had that hooked up to my XP machine. The workstation was wired and we used the wireless capability for my iTouch and our Wii. I got the router and iTouch in May and haven't had a problem with it. As soon as I'm in the house, my iTouch connected and stayed connected. Never ever an issue. A week ago, I purchased and setup a new workstation, an HP p6214y. Because neither workstation has a wireless network card yet, I have them sitting next to each other and both wired into the Linksys router. I can't recall what steps I used to access the XP machine to copy files over, but I did. Somewhere in the process, the Windows 7 machine added the router to the network, renaming it and even changing the password on it. Ever since then, I constantly lose my wireless connection on my iTouch. Most of the time, when I turn my iTouch back on it has lost the connection and I have to connect. Annoying, but it wouldn't be so back if it connected immediately when I went into settings and tried connecting to the wireless network. But it takes at least 20 clicks on thing to finally get connected. Then I stay connected again until I set it down and pick it up again. I have tried rebooting the router. I have tried resetting my router settings (also renaming and changing the password) using the IP address and the reset button on my router. I disabled the Power Management on my NIC card. I've Googled this and have found a ton of similar and related wireless issues, but nothing conclusive to fix it, and everything that I have tried so far hasn't worked. I would appreciate any suggestions anyone has to offer. TIA!
ETA: I have also tried (many times) rebooting my iTouch. I have also updated the drivers
on my NIC card, which is a NVIDIA nForce 10/100 Mbps
