Your wifi issue sounds like a bad DNS server. Are you experiencing that issue with other hardware on your network? Even so, I recommend OpenDNS since they're faster. You can run diagnostics on almost any machine with namebench from Google Code.
In some cases I recommend Google DNS but I don't like giving them more information about me and my browsing habits.
To answer your question, I haven't tried the Nexus 7 but I'm hearing glistening reviews on it. I just got an iPad Mini and I like it. Though iOS 7 hasn't grown on me yet and it keeps crashing my iPhone!
Best of luck!
