OK, I have finally solved "part" of my wireless issue from 3 days ago - I can now connect to one of my wireless routers upstairs (the problem ended up being not having channel set right). The downstairs wireless router worked (as set up below) with another device but not my notebook. The downstairs router is piggybacked onto a LAN port on the upstairs router - here is the topology:
Upstairs (D-Link DI-524)
SSID aaa, channel auto, mix mode, wep, dynamic IP address, hostname DI-524, LAN: 192.168.0.2, DHCP server enabled
Downstairs (D-Link DI-524 into LAN port of above router)
SSID bbb, channel 4, mix mode, wep, dynamic IP address, hostname DI-524a, LAN: 192.168.0.3, DHCP disabled.
What fails is trying to get dhcp through the downstairs router. It should pick up DHCP from the upstairs router but is not. What should the "iwconfig" statement look like or should I set up the downstairs router differently?
Any help greatly appreciated.
