HELP! Can someone please tell me why I can't get connected with this thing? Here's what I've got: 2 PC laptops 1 Mac Mini desktop WRT54GX4 Firmware version 1.00.19 The router is being used as an access point ONLY. There's already a DHCP server set up in the office. There are at least 6 other wireless networks in the area. I've changed channels on multiple occasions, and moved the unit to different locations in the building. Moving the unit less than a foot, or rotating it will DRASTICALLY affect its wireless performance. Wall-mounting the unit seems to actually make things WORSE. There are NO other networks on my channel (currently set to 10). There are NO cordless phones in the office. Encryption is WPA-TKIP. All wireless settings are set to DEFAULT, except the "network density," which I set to "high." As long as everything is in the same room, it works fine. Moving ONE ROOM AWAY causes dropped connections, or an inability to get an IP address. The building I'm in uses standard wood framing with sheetrock walls, and there are windows between each room. With a plain-jane WRT54G, I get EXCELLENT range and no drop-outs. Unfortunately, that router had to be moved to another location and converted to a wireless bridge. With this GX4 piece of s**t, I get terrible range. Something else strange: My Mac can connect to this router all day long with no problem. The PC laptops can't seem even GET a connection with this thing. I'm to the point of reaching for my trusty sledgehammer, smashing this thing to bits and mailing the pieces back to Linksys. I have NEVER had this much trouble with a wireless router--even my piece-o-crap DLink that I use at home is better than this thing. Can someone please tell me what I'm doing wrong, here? ANY help that anyone can provide will be greatly appreciated.
