Unstable home network due to interference?
I have this modem router smart rg sr505n in my basement on a FTTN connection. I notice that throughout the day, the ping time from my computer to the modem could be as high as 3000ms, and it should normally be <1ms. As a result, even 480p youtube video streaming is choppy from time to time. I had this modem on the first floor before and never experienced this issue. So I have been suspecting there are some interference in the basement causing it. What is a good way to find out? I do notice that there are a few exposed wires near my modem, left behind by a bell technician who was doing some tests. Not sure they could be causing issues.
