My wifi keeps cutting out on my pc

[cheesy_iron]

Ever since i put my PC down in my room my WiFi keeps getting disconnected. I still have 4-5 bars but no internet. Its a Wintec FileMate PCI. Its getting very frustrating! My router is a NetGear WNDR3400v2. When i use network troubleshoot it says that it fixed "no default gateway" but then it goes back out again. It goes out every 30-45 minutes for like 3-7 minutes. I set sleep-mode off. I really don't know what to do. My Ipod touch gets 2 bars and never goes out. Any help would be very much appreciated

Try changing the wireless channel in your router's configuration manager utility.

It was on auto. Ill change it to 4 or 6 cause that's what happened to some other people. Ill check back later if it cuts out again. Thanks for replying.

Edit: I think that was it, it hasn't gone out yet. Thanks for helping. I was going to go out and get a different wifi adapter.
