Connect the router and access it via 192.168.1.1 do a factory reset and power everything down! (modem, pc and router.)

Wait 5mins then power up your modem, wait a couple of mins then power up the router and wait a couple of mins now the pc!

see if that makes any difference if not check for new firmware version via the the linksys website and upgrade if available!

If that does not work, power down modem but leave everything else powered up then after 30 seconds try powering up the modem! (If memory serves me right my v7 would not connect via the net unless I powered up the modem after the router had been powered up.)
