Thanks a lot for the help information! I really appreciate it...
If your wireless router and wireless phone are both using the same or adjacent channels in the 2.4ghz spectrum, then they definitely can interfere with each other. If possible, use channel 1, 6 or 11 on your router and a channel at least 2 channels away on the phone. If you can see your neighbor's router(s) and what channels they are on, try to avoid the same channels (the further away numerically, the better).
