it was "NetWorx" bandwidth monitor program's fault!!!
FFFFS!!(for fat flyin' F%^$'s SAKE!)
after 7 or more days...
...of calling my ISP each day...
ticketing steam(no answer YET!)
reinstalling eveything with this very slow internet(i live in middle-east)
from Steam to Dota & lots of other programs like Sype, Anti viruses...etc
not WANTING to reinstall WINDOWS(cus its absurd to do so, when u can fix the PROBLEM not burn the HOUSE!)
i figured it out!!!
by disabling each program 1by1!!!(diagnosing the problem flowchart way)
it was "NetWorx bandwidth monitor"
it has a kinda protocol or whatever...
that after i patched to 6.83 i did get 5-30seconds Auto Disconnects accured!!!
(maybe after patch valve changed some connectivity stuff(that i'm not an expert of...)that conflicts with the NetWorx)
so PLEASE PLEASE PLEASE PLEASE...
Valve...
do care more & list more of these programs or at least ANSWER UR TICKETS FASTER!!!
people need help they love the game and pay for it AT LEAST GIVE THEM THE HELPING HAND(faster)!
so...
Tl

R
delete/close
all programs from task manager or use(Task Killer 2.30 program)
...& then DELETE STEAM OR DOTA or WINDOWS!
REMOVE:
"NetWorx bandwidth monitor"
*P.S. i will try to REPORT this issue to the NetWorx bandwidth monitor company cus i love that little program...sad to see conflicts.
*P.P.S. dont be lazy, please report/submit/post, help people, change gamer lives...even if ur english is not perfect. spend some(10-15min) to make some1 happy.
>>>i still have a friend that charged up 20$ wallet with so much effort & now he cant even use that 20$.....why u ask!? cus he lives in Middle-east, cus Steam is blocked/filtred in my country & we must use VPNs to access it and then IP conflicts with steam wallet charges/marklet transactions & boring security issues that Valve dosent care much about ...... so sad to hear such stories of carelessness when ur only source of happiness(cash) are in our pockets....care more about US! :}
