Hello,
I'm connected to internet only by Wifi and I have no cable connection.
The thing I'm trying to do is use mine wireless internet connection, but at the same time be able to connect to router that I want to config via telnet. Router is connected with cable, but there is no cable from router to internet.
How to do this?
Only thing I can do is to use only one connection once.

Thanks for a help!

Easiest way to do it I can think of, is to simply assign a static ip in an unused subnet to eth0 + the management interface of the router. So lets take the 10/8 subnet as an example. Assign 10.0.0.1 to eth0, 10.0.0.2 to the management interface on the router and route 10/8 over your eth0 interface.

Actual config would be:

# ip addr add 10.0.0.1/24 dev eth0
# ip route add 10.0.0.0/8 dev eth0

So first line is for assigning ip to eth0 interface, and the second one in asigning routers ip to that IP?

# ip addr add 10.0.0.1/24 dev eth0

Assigns ip 10.0.0.1 to your eth0 interface.

# ip route add 10.0.0.0/8 dev eth0

Tells your Arch to route connectivity towards any address in the 10/8 subnet over eth0. So if you then assign an address in the 10/8 subnet to the router (and anything else besides the router you want to play with); you can access it all from your Arch box without it interfering with your internet connectivity.
