Can someone help how I would lock the BSSID in luci? I am in a hotel right now and having the same issue. The SFT1200 seems to be jumping between multiple BSSIDs and is dropping connection every time. It is completely unusable.
I've tried to edit the sta interface, add a BSSID and save the connection, but it keeps changing through the BSSIDs...
The SFT1200 seems to be pretty bad device. Support is horrible and I have the feeling that even gl-inet does not really have it under control...as it seems to be based on one version of openwrt which was compiled once by the chip/board manufacturer...and that's about it.
Ok, so I got curious and had a look if there was a new upgrade. But the interface didn't show any. I went to the product page and there was a firmware upgrade to version 4! Too bad the upgrade section does not show that.
I now had the option to lock the BSSID...but it unfortunately didn't solve the issue. I've now disabled the 2.4 GHz network of the router as the hotel wifi is 2.4 GHz. I also set the option to only use 20MHz Bandwidth. That improved the issue a little bit...but still not really stable...
Just for anyone that passes here and has the same problem.
I don't really get it to work. I don't know which hardware is used on the hotel side but all devices work except the sft1200. It drops connection all the time. The access points only provide a 2.4GHz network with a lot of APs (I can see about 4-6 all the time).
I have it a little bit stable (enough to receive messages and mails and very light surfing, no video) with the following settings:
Turn off 2.4GHz network
Try to connect once through the GLI interface (if that works)
Switch to legacy mode in the networks settings in luci
Select a distinct BSSID (only one works in my case which is not the one with the best signal! All the others, I could never connect to)
I was never able to add the network in luci. It always instantly disappears (a bug?).
I don't know if the OpenWRT version is just to old...but the SFT1200 does not seem to be a reliable device. It is not the first time I am having problems connecting to networks...but I am also tired to use my vacation to find workarounds for issues.
... and only have one (1) SSID in the known network list. BSSID lock is only for that network! SFT1200 will jump to other known networks for just no known reasons.
BSSID Lock: It can be set at "switch network" time, via advanced setting, after selecting the network in "join other network", and it then can be locked into that BSSID. Once done with that BSSID Lock enabled, then the menu option will be available for further modification or to be disabled, for that network only, where it was set.
Yet another extra step could be to set fixed (manual) IP, because that disables the "hotplug" action on the WWAN interface when the connection just disconnects/reconnects. Hotplug action is renew DHCP but also reload Firewall and NAT TCP sessions.
See WWAN in Luci :
"Force link
Set interface properties regardless of the link carrier (If set, carrier sense events do not invoke hotplug handlers)."
