My laptop (Lenovo ThinkPad X300) uses Sierra Wireless USB modem, as seen below: linux-ft0m:/home/aaada # /usr/bin/lsusb Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 002: ID 1199:6813 Sierra Wireless, Inc. The internet-connection through operator's 3G network worked very fast and very reliable out-of-the-box with openSuSE 11.0. Knetworkmanager found and run the modem very fine. Now there is, however, a ramdomly appearing problem: The network sometimes works and sometimes not! Purely random pattern as fas as I can see... About one case of five works and others not. The system does not seem to get the DNS-service... The log below is from an unsuccesfull case (it is a bit old, but I did not get around this issue any sooner): May 2 11:18:47 linux-ft0m NetworkManager: <info> starting...

I tried to get a log of a successfull case, but now it seems not to be able to connect at all... The HW seems to be OK because Windows works fine, thank you...

As far as I can tell, it seems to be the case that the software gives up too early before being able to get the actual DNS and routing information. I did, by the way, a complete new install on this machine, not an upgrade. It seems that if I allow my machine to update itself when using 11.0 then the same problem appears with 11.0 also... 11.0 is retail and 11.1 is openSuSE. Best regards JJA Reproducible: Sometimes Steps to Reproduce: 1. Boot machine, log in 2. Try to use Internet through UMTS modem connection 3. Open a browser and try to contact to www.opensuse.org Actual Results: Browser says: Unknown host. Expected Results: Successful use of DNS-connection and Internet. What makes this strange is that not-at-all-updated 11.0 (retail) works fine but it stops working after automatic updates. In addition to that, 11.1 (openSuSE) has this problem with or without any updates. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
