Does anyone know an update on this issue?
I did some tests today trying to solve some WiFi issues and found that I simply have the same problem on an 860L on the 5GHz radio.
With LEDE 17.01.2 "N" on 5 GHz seems acceptable (but still kind of feels low ranged), but "AC" on 5 GHz is bad at all.
- sporadic timeouts
- slightly increased ping
- low throughput
- very low overall range
- varying low throughput
Tried the magic rollback to stock firmware, go back to LEDE, as described earlier in this post, but that did not improve my situation.
I am sadly back on stock firmware now. WiFi throughput is fine now, but the situation is sad: Stock FW only has 5 wifi channels in 5 GHz (LEDE 20!), it's a 2 year old firmware and I miss my custom packages
According to https://forum.openwrt.org/viewtopic.php?id=64333, DD-WRT seems to not be affected by that issue, so I might try that, yet dd-WRT does not seem to have custom packages.
