I am helping a friend set up his VPN from the UK to the US. We are running into some issues with the Beryl 7 WiFi is not stable. He is using it in router mode and is hard-wired to his upstream router. So the known issue of repeater mode is not part of this config.
At least once a day, the SSIDs will either disappear or stop allowing connections. When this happens, he also has issues with the LAN port not always allowing connections. Clients seem to bounce between 5ghz and 2.4ghz in an almost flapping occurrence just before the SSID drops clients. They are currently testing with a wired client to see if it improves, but it has only been a few hours.
A power cycle will usually fix it.
No AdGuard, DPI, or anything else. Tailscale is installed; custom exit-node is not configured.
FW version = 4.9.0
MLO = Off
WPA/WPA2 - On (WPA3 is not enabled)
Channels are fixed, not automatically selected
Non-DFS channels are being used
Any suggestions on how to troubleshoot the drops? He has 3x Beryl 7, 1 in UK, 2 in the US. Due to the instability on at least 2 of them (3rd one was just installed yesterday), we are unable to proceed with setting things up. If an older firmware will fix things, stability first, then VPN setup.
