That sucks for you, hope you get better net..
Did some more testing.. I turned TCP/ DHT network back on and changed the max half-open to 4, but ALSO changed the torrent connect speed rate, an option they DON'T cover in their supposed fixes for speed problems.
Everything is running smooth right now just below 75k/up. If I let it auto throttle the speed I can peak up around 100k/sec and a little over but it starts to affect the ping, still much better than before when the whole connection crapped out.
I've got it set at 90/max right now, pings stay good, although I dunno if its because I'm using a newer version of BT or not but uploads for some torrents and downloads are incredibly slow, irregardless of the slow bt_connect speed setting. Might try going back to 1.8 and changing those settings there, if I can keep TCP will only help with speed obviously, but UDP is not bad either as long as I can't find people who support it.. The setting for UDP only exists in 1.8 stable, also, but am unsure if it will do the same thing there.. I think the most important setting is the connect speed change from 20 to 4.
