when was this ? Sometimes the problem is due to steam upgrading works or overloading  .

firstly , u need to identify the source of your delay  , perhaps double check the speed using ur phone and pc  .

If the internet speed is fine , means the connection to steam having problem . Also please make sure no one is torrenting at home  .

Alternatively if the source of the problem is isp , lodge a complaint , take down the internet speed info and forward to them .

From what i understand , some places have too high users which the call center ppl are unable to do anything about it .

Pay abit more and move it next to ur pc and use LAN
