==================================================
I ran Netgear Genie, and apparently there's one router on channel 2 and 3 routers on channel 6. I use channel 11.
I did try to change my channel when I started having these problems (my old channel was 1, and I also tried 5 and 6), but changing it didn't help. I have an app on my phone that said channel 11 would be the best, so I've used it for some time now.
