I have a WRT54G router (v5 i guess -_-), with optimumonline. The router is connected (with ethernet wire) to a PC and a VoIp Device, and also two wireless machines. The trouble is whenever someone goes online with the wired PC the wireless internet connection goes out. The signal is fine but there is no data, and also, when I try repairing the connection, it'll stuck at refreshing IP and then sometimes show limited/no connectivity. I tried disabling the wireless security but to no avail. Also, the Voip device has port triggering, i dunno what that does. If I unplug everything and turn them back on, the setup works for about 10 minutes before the wireless dies out again. All throughout this process the wired pc still has normal internet connection.
