Hi, I am running Win 7 Pro 32 bit and the modem I'm using is UT300R2U. Everything was running okay for about a month since I upgraded to Win 7. Of late I've started getting DNS Client Event errors which appears in the System Log Files as name resolution for the name [URL] timed out after none of the configured dns servers responded. ..and the modem simply freezes. The only way to get the modem reconnected is to re-power it. I have searched through the microsoft forums and the web and applied almost every single suggested workarounds, but to no avail.

Thanks!
