It used to always be 4-5 bars one room away from the router. Suddenly, it's only 1-2 bars, and I have been noticing connection problems. I have tried resetting my computer, the router, and the modem. Even when I move into the same room with the router, I only get 4 bars out of 5. I didn't change anything or add any new devices. No phones, either. Changing the router channel doesn't help either.
No other computer or device on the network has experienced this problem. No new devices have been added to the network. No new devices in general (phones, etc.) have been added to the house. I have tried uninstalling and reinstalling the wireless network card, it did not help.
