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

**asan42** · June 15th, 2013

when i first turn on my desktop and open Firefox it opens Google as the home page no problem. i can surf the internet for about approx one minute then it tells me Firefox cant find server at start.ubuntu.com and stays that way until i turn of completely and turn back on. then same thing.

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?

i changed settings on router and got same affect. you think it could be the router? should i change it out?

**chili555** · June 15th, 2013

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.
