@Vanadiel you are saying that we should keep `UseDNS on` ? if so Bell needs to fix their side. I am connecting to the ssh a lot per day, loosing a lot of time because of this issue...
I have the exact same problem with SSH... only happens on Bell Wifi at home (tried at 2 homes with BELL). using hotspot (fizz, bell) or wifi on other ISP, I have no problem. How did you disabled dns check?
