Hi there ....

I used to play MW3 on 4D1 for 4 months but since the last two weeks it started giving me Steam Authorization Failed ???? I think it's related to my network provider coz when I change the operator this error disappears ... so, is there anything I can do to fix my current network I mean any suggestions for the provider to fix it ????

HI,

i got mw3 on Steam and on 4d1 i searched alot in the internet till allstuff works^^

i just create a folder in your mw3 folder ( the one u are using to play with iw5m exe) and call it dw and it wount request steam. i just do it couse i have low intenet connection and i dont want steam (or anything else that uses internet )to run while i play.

You didn't.

 

Anyway, that issue is not related with that.

As he mentions, it happens only when he uses a specific internet connection.

So, I think that specific router is blocking the game port (port 3074 UDP). Forwarding that port on that router should fix the issue.

And adding exceptions on windows firewall and antivirus, right?

Could be that, but he mentions that it happens when he changes to a specific ISP. The only firewall that changes in that situation is the router's.
