3G/4G internet connection sharing -- help needed

Running W7 Ultimate.. T-Mobile Jet usb modem ... Linksys E1000 router.... PS3 ... Motorola Xoom
ok now heres my issue .... after about 8 hours had it all working just great for about 2 weeks then when i tried to connect my PS3 keept getting BSOD with Bad_Pool_Caller tried the Xoom same thing.. so i uninstalled all the drivers for the USB modem and NIC .. reinstalled.. and now after 6 days i cant get ICS to work again... NIC is set to router (router has been "made" into a switch disabling auto ip ect... ) if i try to share my USB modem now.. the host machine cant even use the internet ... and since i live in the freaking boonies.. this is my only means of sharing a internet connection.. my other old xp machine still can share it.. but after 20min of run time it shuts itself off hence i got this new wonderful Windows 7 machine.. and well.. think im gonna wipe it and install XP64 .. unless i can get this issue fixed any ideas ?:)
