vista...after cleaning some malware and virus from a vista home basic pc...it will not now connect either by the nvidia nforce network controller ethernet card or the huwaei e160 mobile dongle....diagnostic reports says that tcp/ip 4 and 6 need to be configured on the network card but they are shown as both configured on the card. the connection works on my other pcs. also the huwaei e160 dongle shows an 02 uk network present and available with strong signal but will not connect (I have checked it on another pc and it works fine) ...I have updated both sets of drivers and used a microsoft fixit's to reset the ip stack and the ie winsock. LAN is set to automatic etc. I also uninstalled and reinstaled the onboard nvidia card.
