So, you have slower internet than you suspect you should, and you own a Sonic Wall firewall, well, there just may be a solution! Or, rather, a temporary fix with lots of awesome reference data so you can understand what is going on.
P.S. SonicWall, if you read this, can you go ahead and fix it through a firmware upgrade so I don’t have to call your support line and be on the phone forever. K.Thx.Bai.
