The route in question: Ethernet cable - Slackware 14.1 workstation (192.168.1.130) - Slackware 14 home server (192.168.1.117). Via my ASUS RT-N16 running some build of TomatoUSB firmware which has been rock solid since I set it up three years ago.
All of a sudden, scp completely stalls on me, no matter how small files I want to copy, or how small I set the frame size to be for the scp session. This has never happened before and everything has been rock solid until this started in the midst of my assignment season a.k.a semester.
Restarting rc.inet1 seems to improve the matter slightly as the stalling will occur, but not as bad as a complete halt. All the other nodes on my network can scp to both my workstation and server just fine. It's just the route between these two nodes.
Another annoying problem is that I cannot get an ssl connection from my workstation to an owncloud instance on my server. All other nodes connect just fine. I've tried these browsers: Firefox, Chromium and Konqueror. On Firefox I get this error:
"Cannot communicate securely with peer: no common encryption algorithm(s). (Error code: ssl_error_no_cypher_overlap)"
I have done tons of searching, but haven't found anything helpful. I have tried to reinstall mozilla-nss and openssl packages on my workstation, which hasn't helped at all.

Any help I can get is greatly appreciated, as I have no more clues as to what I can do to resolve the problems.
