My laptop WiFi signal is weak, it used to be able to connect to the WiFi at the same spot I'm using it now with no problem but after I spent a month using it at a closer range, I returned it to where it was and it stopped reaching it. I don't understand why, same thing happened with an older laptop we had, it stopped reaching the place we used it at after using it somewhere else. It worked fine too, it was fast and everything. Even my Xbox reaches it from the same spot, hell even my phone reaches the WiFi from outside our apartment! I tried rearranging my room but it didn't work, it works fine a couple steps away in another room but not in my room... Any help? Any ways to at least increase signal strength?
