Hi, I wonder if anyone else has this weird issue with their Linksys WRT54G/s and how you manage to solve it. My friend has the same problem too. First of all, I have already tried different firmwares, including stock, thibor, dd-wrt, and tomato, but they all have this issue. Secondly, I have 2 routers, 1 G and 1 GS. Both have the following problem: My routers (G/GS) would drop ALL wireless clients periodically (5 clients, all at the same time), few times a day. XP would show a message about "Unable to connect to preferred network". During this period, the wired side is working fine. All the clients are also able to see the AP/router in "view available wireless network", but cannot be connected to. In a period of about 1-2 minute, the clients sometimes can connect back but then get dropped immediately. After about 2min, the clients connect again so everything is back to normal. No microwave running, no 2.4GHZ phone. I originally thought it was WDS problem, so I only used 1 router. It still happened. I then thought it's WPA problem, so I switched back to WEP. Needless to say it is still happening. I swapped both G/GS routers. I have also tried ALL wireless channels. Same problem! The log does not mention anything about these events. Does anyone know what the problem is? And how do you manage to solve it? Thanks in advance.
