OK. I'll wait for the newer version.
Going back to the stable version 4.3.24 now, until this beta becomes usable.
Learned a lot on GL.inet software and on OpenWRT with all this searching and testing.
Unfortunately this 4.3.24 the current latest stable is still something with awfull performance.
Tested very long to get stable connection, (with BSSIDlock, only one known network, no Multiwan checks, had it stable, but now looking at the speed, it's not good at all.
Just using the built in tool "LUCI-Status-Realtime Graphs" as double check, with setup PC at 3 meters from the SFT (preventing any receiver saturation) , stable signal, this is just bad performance. (Green graph- interface rate)
Too bad. SFT with ALL rev 4 firmwares I have tested and tweaked (2 months, 3h per day) make the SFT1200 no better than a "paper weight"/"presse papier".
Further regression done to firmware 3.216 and this actually works. Missing the new features, but at least this works so far. Heh ... sort off working.
If this also starts to show major defects, the SFT1200 will go back in the box, as my Mikrotik mAP Lite and Cudy TR1200 serve me personally well enough.
Hope to be able to recommend the SFT1200 or other GL.inet to our tenants (21 families), but for now that would be a wrong recommendation.
