I have 2 pc's, one is laptop and the other is notebook. On the notebook I have a wireless connection, while on the laptop a cable one. Since I have a wireless printer, connected through the modem router, few days ago I installed it on my laptop taking the wireless signal with a usb receiver. Since then, my connection, both wireless and cabled, and in all of the pc's, got as slow as 10% as before.
Has somebody encountered the problem before? How to fix it?
