no net after upgrade 7.04 to 7.10

4 posts · originally from https://geek.digit.in/community/threads/no-net-after-upgrade-7-04-to-7-10.71945/

I upgraded using the alternate CD. however, after upgrade, i can't access my net connection.
i have set it up as static ip.

i can ping any site and visit them using their IP address, and after adding respective ips of ubuntu repos, i can even update my system, but otherwise there is no net access for me.

One peculiar thing i have noticed is that previously, in 7.04 the network option under preferences showed eth0 device, while in 7.10 it simply shows "wired connection"

Please help.

ur problem only with browser?
there is some problems with gutsy read regarding slow net speed and disabling IPV6 as a solution.

if u can browse using IP no,then it is a DNS failure from ur ISP?
did u tried browsing IP: 198.65.131.97 (digit) in firefox or any browser?does it worked?then it is a DNS resolving problem.I suggest u use *opendns.com service for faster resolution.

check ur /etc/resolv.conf .also ifconfig o/p.sometimes routing problem too happens.

use the troubleshooting tools

Code:

dig google.com

Does the DNS server reply?

[/code]traceroute www.google.com[/code]
does the routing work well.

Code:

route -n

is the route set fine. unlikely that there's something wrong here but just to double check

Code:

ifconfig eth0

check if the ip address is assigned fine. Also, check Errors section, are there any errors?

oh well, i simply wiped the files /etc/resolv.conf and /etc/network/interfaces clean and using the network manager recreated it.

also added metric 100 in resolv.conf and after reboot, the connection works like a charm,
