[gentoo-user] USB modem locks weirdly

[Clara García]

Hello, I have a Huawei USB E220 modem wich works fine almost all the time. But sometimes when I connect, it seems to work OK (led turns continous blue and wvdial shows exactly the same as when the modem connects well, no errors) but there is no connection to the internet, I can't use anything related with the internet, I can't ping google or any web... 
 
 It happens when: 
 1. Sometimes while connected. 
 2. Sometimes connecting (Sometimes randomly or if the 1. case happens, it's for sure modem will hangs up connecting). 
 3. Always if unplug/plug the modem (Even if the computer is poweroff). 
 
 The modem doesn't connect correctly again until I fix it, so I can say the modem "locks" better than "hangs up". The worst and the weird of this problem is the solution; when the modem locks it won't run again until I reboot to Windows, connect to the internet there and reboot again to Gentoo, then the modem works fine again (until next time). 
 
 As you can see that is painful because: 
 1. I need to reboot two times to get online again on Gentoo. 
 2. It makes me have a Windows installation only for unlock my modem! 
 3. It can happens a few times in a day. 
 
 ¿Anyone knows a way to unlock the modem on Linux? 
 
 
 Thank you in advance and sorry for my english.

I don't, but this guy seems to know what he's talking about:

http://ske.sourceforge.net/html/projects/huawei/huawei_tre.html

I hope this helps.

Thank you for your help but that not very useful for me, that is another way to connect which I can't use because he use some ISP parameters which I can't replace.

When modem locks if I ping google.com I just get an "google.com unknown host" but if I ping google using it IP instead it name (ping 64.233.167.99) my computer sends packets correctly but doesn't recieve response from google. So it is a DNS problem but I have the correct DNS of my ISP in /etc/resolv.conf

Check that DHCP works and you get a good IP address from your ISP.

I don't think so.  It sounds like it when 
> I just get an "google.com unknown host"
that happens, but nevertheless I think the problem is that you aren't
able to recieve packets from the modem.  That may be why you can't look
up the name, because you can't recieve packets from your nameserver.
It also explains why resolv.conf isn't helping .
