I'm going to travel a bit in next weeks, visiting family, but staying in a rv. I'm looking for an easy setup to extend family's wifis to the RV.
So first I bought an ubiquiti mesh UAP. 1st choice, if I can easily plug it in existing router + long cable, I'll be ok.
But now I wonder what I can do if no port are avail/no window to run cable outside/not entering their home because of covid. So I got the idea of installing a Pi 3B+ I have with openwrt.
I plugged the UAP wired in the Pi, and the Pi is a wifi client.
After playing around with bridge/relayd, everything works "almost" perfectly.
It works, but I have a lot of packet loss. Changed cables, it doesnt help.
Setup looks like that (from home, will be different on the road)
(macbook) -wifi-> (UAP mesh) -wired-> (Pi 3 B+) -wifi-> (UAP) -wired-> (USG) -internet-
Ping from (macbook) to USG (ubi controller) = ~30% packet loss
Ping from (UAP mesh) to USG (ubi controller) = ~30% packet loss
Ping from (Pi3) to USG (ubi controller) = 0% packet loss.
One weird thing I saw is if I put my wlan0 on the Pi in promic mode, everything works fine (no packet loss), until the Pi freeze.
Anyone have an idea?
