Try this. Edit the connection using the Connection Editor and set IPv4
Settings | Method to "Automatic (DHCP) addresses only" instead of
"Automatic (DHCP)". Make sure 8.8.8.8 is still included in the
"Additional DNS servers" field.
Another thing to try is to disable the local forwarding nameserver. Edit
/etc/NetworkManager/NetworkManager.conf, comment out "dns=dnsmasq" by
putting a '#' at the beginning of the line, and restart network-manager.
You'll need sudo to accomplish this.
** Description changed:
I see this problem somewhere between once a week and once a day: DNS
lookups suddenly stop working causing the browser to fail to load pages
and time out.
After the last time it happened, I figured "must be comcast's flaky DNS"
so I added Google's DNS server 8.8.8.8 as an additional server via
network-manager but it just happened again. Even while it was broken, I
could still ping 8.8.8.8 so I'm not really sure what's going on.
I had a look in resolv.conf but it seems to be the same whether it's
- working or not. Wither way it only has 127.0.1.1 as the nameserver. I
- was expecting to see the actual nameserver in there but I guess Ubuntu
- is using some sort of local proxy DNS? Since I'm not sure how DNS works
- anymore, I'm not sure if this is the right package to report against.
- Please advise.
