    I upgrade yesterday and everything worked well. Today, however, I'm having internet connectivity issues. It's slow to connect/ doesn't want to connect, and internet is extremely slow once it has connected (like dial-up speed). I've tried various networks and result is the same. I've been doing some googling and see others reporting the same.

    Does anyone else have this issue and have resolved it effectively?

    I did. I spent 6 hours with tech support and the genius bar in total. Reinstalled ML, requested to return to Lion, but this was not possible. No fix. I bought a new wireless router. No fix. Then bought the apple airport express. FIXED.

    It's annoying that a belkin and linksys router would not work, but the airport express worked out of the box. I don't know who is to blame. But I had the same issue, Lion internet fast, Mountain Lion internet slow, until airport express.

    It's a nice little router, but at $100, a bit steep.
