I have 2 lans connected through a short wifi bridge across the street (20 or 30 m.), consisting in 2 cpe210 antennas. This setup is stable and works perfectly almost all the year, but for some days when a local festival gathers some hundreds of people in the area (but no electronic infrastructure, no wireless microphones p.ex., just a lot of people).

These days, when a show starts, there can be connectivity issues (maybe due to interference from mobile phones?). Both stations say that there is strong wifi signal, and appear to be connected to each other, but pings won't reach the opposite antena or beyond. When the show ends and people go back to home, everything works normally again. I can't see any abnormal interference or noise levels connecting locally to the antennas, but I'm no expert and I don't know what to look for.

I can live with this, it's just a week with connectivity losses that last a couple hours, but it's very annoying.

Any suggestion?

Thanks!
