Happy New Year everyone. Router : WRT54G v2.2 Firmware : HyperWRT with Tofu6 based on Linksys firmware 4.20.6 The router serves 2 clients, one via a LAN cable to my desktop PC, and the other via wireless to a 11b Lucent Orinoco card on my notebook. I tried doing a large file transfer of a 500MB file from PC to notebook but about 10 seconds into the transfer the notebook was disconnected and lost its IP address. The Lucent card could not detect the wireless signal unless I reinserted the Lucent card into its PCMCIA slot. However, on the desktop PC it was still fine - the web was still browseable, and more importantly, the router did not disconnect. Do you guys have any ideas why wired <-> wireless file transfers are still being disconnected? I thought Linksys had fixed this issue ages ago. - Router is set up to PPPoE into a DSL modem - DHCP enabled - SSID is being broadcasted - no wireless encryption used FYI my startup script has only this line : echo "600 1800 120 60 120 120 10 60 30 120" > /proc/sys/net/ipv4/ip_conntrack_tcp_timeouts and the router has been working like a charm, bar this wireless disconnection issue. Any ideas to this problem?
