Hi,
I’m running a recent tumbleweed version and I’m experiencing since several days a huge slowdown in my network / internet connection. I have a Lenovo T420s, tried both built-in (Ethernet and WIFI) adapters and another USB Ethernet adapter and having for all the same issue when using tumbleweed. When running windows 7, the network is fast as usually. ( The same happens for another Lenovo laptop I have running opensuse 12.3 ) I’m not sure what kind of measurements or data to provide, but I think these may already show that there is a problem:
time route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.178.1 0.0.0.0 UG 1024 0 0 enp0s26u1u2u1
192.168.178.0 * 255.255.255.0 U 0 0 0 enp0s26u1u2u1
** real 0m15.053s**
user 0m0.002s
sys 0m0.003s
It takes roughly 15 seconds for the route command to finish, that corresponds roughly to the delay I’m experiencing when browsing any website. Also the ping is very high:

The connection to my router seems to as fast as usually:

I really apprecite any help. Thanks in advance!
EDIT:
What is maybe interesting is that the ‘ip route’ command is much faster:
time ip route
