English Network/Internet

Being in China has some disadvantages reagardings internet.
To enjoy unfiltered speed and access I use my non mainland mobile phone card.

Using LAN works fine in the office.
But if I connect the WLAN USB dongle except skype nothing works.

somehow firewall is blocking?

dmesg

I’d say a DNS or routing problem.

Check “/etc/resolv.conf” and your routing table when “everything” is working and when just skype is working. I guess You know this but just in case use this command to check your routing table :

route -n

This looks fine.

What about

cat /etc/resolv.conf

When it’s working and when it’s not ?

cat /etc/resolv.conf

showed me the DNS for china telecom.
strangely, becausse I entered google’s DNS within YaST.

/etc/resolv.conf.netconfig were the entries.
i edited /etc/resolv.conf manually and now it works fine.

Thank you for your help
