Hi, i have 2 win 7 ult. pc's. one is using a vodafone usb 3G modem to connect to the internet. they both have gigabit nics. i tried using a crossover and now a straight cat5 cable, but both lan connection come up as unidentified network. Pc with 3G modem can connect to the net. when you look at network connections it says the following. -(3G pc) vodafone mobile connect/work network/internet access unidentified network/public network/no network access -(other win7 pc) unidentified network/no network access/no internet access. Please advise.
