Hi all, I've recently updated my Hero to 2.1 & am now unable to tether it to my laptop. It worked when I had the old firmware on the phone. I've installed the new version of HTC Sync but whenever I try to connect via the phone (after selecting internet sharing on the phone) it connects to "a network" but then the next link in the chain, a connection to the internet has a red cross through it. When I ask Windows to diagnose the fault I get the error message "DNS server isn't responding". I'm on Windows 7 64bit if that makes a difference. Any ideas?
