We bought my mom a new cordless phone (really nice one) for one of her christmas/birthday gifts. It's a 2.4Ghz. Now I wondering if maybe we should have. Right now we have a 900Mhz (I think) and it doesn't interfere with the wireless router at all. I have a Linksys WRT54G -- anyone have any problems with this router and a 2.4ghz cordless phone?
