Ok, the main problem is when i use Steam games like Team fortress 2, Garry's mod, ect. Every time i try to search for a server it disconects, i don't know why.

 

 

 

Why i know? Every time i reset(Turn on, and off manualy) the router the internet cames back, my conection is a Blekin one, i alredy put all the possible TCP and UCP that can handle that the website Steam alredy said but i still encounter this problem, also i know becouse it happens on every computer, this one, my dad's laptop and my ''school'' laptop and happens the same, i also don't know how it started it was very random.

 

 

 

Any solution?

If it's just for when you use steam then it might be a problem with the QoS(Quality of service). Go into the router control pannel and see if there is an option to turn off QoS.
