Losing Internet Connecrtion quickly

English Network/Internet

Hello, I keep losing my Internet Connection(DSL) very quickly. Usually after a couple of minutes, it’s absolutely unpredictable. And then, it gets difficult to reconnect. And if I succeed in reconnecting, I again lose the connection quite quickly.

Here are some logs from the ifcfg-dsl0.log:

SuSE Meta pppd (smpppd-ifcfg), Version 1.60.46 on linux-6clg.

I don’t have this problem with my old computer(I guess, Suse 10.3?). And I have this problem with two different modems.

Please help!

Sorry, “Losing Internet Connection quickly”.

I don’t know how to change this, if somebody wants to change this, no problem.

Did you already set the option for the connection NOT to auto-hang-up for inactivity?

4

Maybe try and put in /etc/ppp/options

lcp-echo-interval 0
lcp-echo-failure 0

so you do not get disconnected due to a no response to the ECHO request.

Cheers

Thanks a lot ghostintheruins!

Actually, I still had problems afterward. As my computer constantly messed up with the DNS-Servers. Strangely, it seems it all got better after I had played with the “Udev”-Rules.

But your answers helped me a lot!

I will do some further tests in the coming days. And I hope everything will be alright!

Glad I could help. :slight_smile:

Regarding the dns servers I guess you could use manually set ones (e.g. google’s or opendns) and set your connection NOT to update / change them (I mean /etc/resolv.conf), this unless you need to use your ISP’s DNS servers.

You can use also your ISP ones if you know them and if you are sure you do not need to let them change automatically.

Check: https://code.google.com/speed/public-dns/ and http;//www.opendns.com/

Cheers.

I’m sorry, it didn’t disconnect anymore. On the other side, I couldn’t transfer data from or to the Internet.

I guess the problem is linked to the drivers:

Wired internet - keep loosing connection
