Hi, there... Having recently joined this forum, I hope to find help with a current situation involving a WRT54G router. I purchased the router last night, however I've run into serious problems each time I've attempted to connect it. When I connect my cable modem directly to the CPU, the direct line produces a speedy and a reliable connection. However, when I setup the connection through the router, the cable connection immediately drops and I'm left with nothing. The modem just sits there attempting to startup again, but goes nowhere. Each time I connect it, it's the same thing - regardless of the order that I power-on the router/modem/CPU. On the odd occasion that it does stay connected, the speed is borderline dial-up and hardly worth the trouble (and then it disconnects about 2min later). I spoke to various Linksys reps today for just under 2 hours, but ultimately got nowhere. One told me that Linksys routers weren't compatible with my ISP's (Cogeco) modems, but after speaking to a Cogeco rep, they quickly dismissed that claim (Cogeco uses a variety of modems and has numerous customers using Linksys routers and other products). I stumbled across this forum in search of an answer, then downloaded a firmware upgrade, but it changed nothing (other than lighting up the Cisco logo). I've also tried adjusting the MTU setting to 1400, but nothing there, either. My system details are as follows: On the network: A desktop PC running WinXP SP2 (wired) and a PowerBook running OSX (wireless). The router: Linksys WRT54G v.3 The cables: All connections are with RJ45, none with USB. My ISP: Cogeco Cable If anyone could help with this problem, I'd really appreciate it. It's really frustrating shelling out over $100 CAD for a router that knocks out the connection each it's hooked up. Thanks very much!
