Computer not (or hardly) connecting to the Web

Hi there

We have two laptops with Opensuse 11.1 at home. I configured the network settings (Knetworkmanager) of both computers with the SAME values, and they were both working fine until a couple of days ago when my wife’s computer stopped logging to the net. Actually it has (rarely) accessed a few pages over the time I’ve been testing it but it does so really slowly (and they are not pages on the cache memory).

The wifi connection is running OK and the problem remains when I plug the ethernet cable in.

Obviously something must have changed during the past few days in this computer but I cannot figure out where to look for an answer.

Any help is appreciated. (she is using my computer now :))

Can you post here the output of this command (from both machines) please:

sudo ifconfig

That will spit out the configuration of all your network interfaces so someone can maybe help out :slight_smile:

Are the two laptops identical in hardware? With the troubled laptop, can you access the router easily using the numeric ip? Can you access sites using numeric the numeric IP? Try putting the result of ‘net lookup www.google.com’ in the url address bar.

If it changed all of a sudden, maybe an update has caused it. Try to think of the exact date that this event started happening. Most likely a kernel update, even though I updated my kernel as well soon but all the trouble I got into were a couple of sound configurations. Once again, if it happened all of a sudden, there is not evident reason why, probably an automatic update has caused it.

I had a similar problem as a result of recent automatic update of NetworkManager. I reverted it to original version and everything seems to work again.

Thanks to all

Here go the the outputs of the ifconfig command for both computers

Hi again

I tried accessing a few sites using the numeric IP and it worked! So I guess is a DNS related problem (caused by an automatic update?). I tried checking whether Knetworkmanager had been updated lately but I couldn´t figure out how to do it.

Thanks to all for the help

Cristian

Try resetting the connection in networkmanager using a static IP and DHCP. Select ‘Edit Connections’ and go through the menus before you click finish. I would guess the routing table is not getting updated.
