Thank you for getting back to me,
I moved the router, the desktop computer is on the floor in a corner away from the router, and there is nothing near the router. I spent the afternoon going through the 11 available channels. I would get a good signal in the computer room, with an apple Ipad. I went into the bedroom about 50’ away, and the signal dropped so low I could not log onto any web pages. This happened on each channel. I can see the networks of two of my neighbors, their signal strength is the same in both rooms. The only time my signal is greater is when I am in the computer room near the router.
Anything else I can try?
