    I see nothing at all wrong here. What happens when you try to open Google with Firefox?

    Re: bcm4234 connection on 12.04 but no internet

    Very interesting. Please restart your computer surf the web until it drops out and then lets see if we can tell what's happening under the hood:
    Code:
    cat /var/log/syslog | grep -e wlan -e ndis | tail -n20
    Capabilities:
    Speed: 144 Mb/s
    Is there any improvement if you turn off N speeds in the router?

    you think it could be the router? should i change it out?
    I think it's possible but doubtful. How do other devices associated with the same router perform? Perfectly or do they also slow to a crawl?

    Do you have a friend or neighbor you can test with? Does your wireless slow down there, too?

    You might edit Network Manager to set IPv6 to 'Ignore;' please see attached.

    Frankly, I see nothing to fix here. Your logs look just fine.
