This problem has been persisting since mw3 first came out. Steam support has offered some fixes, but non that actually works. In this cod forum this question has been asked so many times! and they still havent offered a fix after so many years!
Things i tried:
Turning off Antivirus and firewalls
Turning on NAT settings
Turning on uPnP settings
lowering User Account Control settings
changing download region
reinstalling and updating steam
changing router multiplexing to LLC -based and changing connection type to ADSL2+
Adding program to firewall
changing the amount of pings setting in the steam setting section.
checked VAC ban in the settings section. I am not banned from anything.
This problem is getting too old. we are being sold broken software.
when is COD support, activision, infinity ward and steam going to put their heads together and solve this issue. This is not reflecting very well to their client base.
