Ok, i have found what was the problem , but in a way the new one seems worse.
My computer was some how connected to another router and my router at the same, which made me lose most internet connection. The router it was connected to was a different brand and definitely not in my house. when i click on it it required a pin, which i did not have, then i tried to login to my router, but i got a message saying i was already logged in, which was definitely not. After a while i unplug the power for my router waited a while then plug it back in. when i check my network setting again the other router connect was gone and i was able to login to my router again, i then changed the password.
I use wireless to connect to the router in my house, so i wondering if someone was logging my computer on to that router and also logging into my router and how i can prevent it. Thanks.
