Slow SSH WLAN PI 3

Question

In my home network my SSH connection was really slow and sometimes it just freezed when I typed in commands after I connected to my PI succesfully.

Surprisingly the SSH connection worked much faster when I connected via weaved so I guessed that there is a problem with my WLAN Router.

Update:

weaved changed its name to remot3.it

Answer 1

I found following FIX:

I switched my router's radio channel to another one, that wasn't used by others that much.

Now SSH works like charm on my PI.
