Ok, i would not ask if i didn't search like a moron every possible solution so far. Nothing worked, + my problem is very strange.
The things are like this:
When i connect my PC directly to the modem i get like 50 mbps (normal speed for which i signed the contract), but recentrly i bought a router (some tp-link, not that good, but promised me speeds up to 150 mbps) and my internet speed got stuck at 10 mbps. I thought that's all the router can do, so I didn't mind. After some time the router started to act strange, started to disconnect on it's own etc., so i returned it. I put some difference and i got a better one (why not right?). Today I installed it and BAM, still 10 mpbs internet speed. Still 50 mbps directly tied to modem. If you guys need aditional detail please ask them, I really don't know what else to provide, and i need some help, so, pretty please please don't ignore my problem :D
