i have a wired router that i can plug my usb modem into. could i then run an enternet cable between my wired router and my wireless, meaning the wired router would be acting as a connector between the wireless router and my usb modem???
Best bet is to return the Buffalo router and swap it for a complete WiFi Router with modem. You could try adding an Access Point to the wired router (with the USB Modem connected) but that may or may not work depending upon the configuration. You could try the new Buffalo Router attached via it's LAN to the old Routers LAN port and see if you can configure the combination - you'd like to use the old router as a network switch but as it has the USB modem attached that may noy be possible. The simplest and least complicated way forward is to exchange the Buffalo for a WiFi ADSL Router with an integrated modem.
Ignore my last message - I see that, unusually, your particular router does support the connection of a USB modem.
The simple answer then is "Yes", you can daisy-chain the two routers provided they operate in a different subnet (IP address range). The second router's WAN IP address will actually be in the LAN range allocated by the first router, which is why the second router must use and allocate addresses in a different subnet to avoid conflicts.
I do have a bt voyager dsl router with built in modem laying around somewhere, but i thought this would not work with an virgin broadband connection (becuase it is a bt modem/router). Am i wrong/right in thinkng this????.
If i downloaded the drivers for this would i be able to use it as a modem, plug it into my wireless router, via thernet and bin my usb speedtouch that came with my virgin connection, please help???
Some BT Voyager Routers supplied as part of a BT Broadband package are "crippled" so that they cannot be used with any other ISP. They will only function when a BT Username is entered. Wanadoo are guilty of the same invidious practice with their Livebox routers.
Normal "retail" versions of the Voyager can be used with other ADSL services.
