I'm planning to install a Flint2 as my main router, and on the other side of my house my older Flint1 as accesspoint. I want my devices to be able to roam, so SSID’s will be same on both routers.
Any suggestions for the best wifi-settings on both routers (both operating in 2G and 5G).
If you need 802.11r, Flint1 with original 4.x firmware can support 802.11r in LuCI.
For Flint 2, the original stable firmware does not support 802.11r, so you need use the v4.8.3-op24 firmware. Download link
After that, you can enable 802.11r on both Flint1 and Flint2 from the same LuCI path.
The path is LuCI -> Network -> Wireless -> Edit SSID -> WLAN Roaming -> enable 802.11r and save.
The 4.8.3 and 4.8.3-op24 firmware use different driver branches, so the actual Wi-Fi performance may be different.
You can back up your current settings then upgrade to 4.8.3-op24 and test it in your own environment.
If it does not meet your expectations, you can roll back to the firmware version you prefer.
