Sonoff L3-5M won't connect to WiFi

Hi all, i just got the Sonoff L3-5M led strip and I have issues with connecting the strip to my WiFi. The strip can be added via Bluetooth easily, as you can see from the pic below: [dashboard] When I open the strip from the eWeLink dashboard I get this message: [pop_up_info] This should be ok too, it says that there’s a new firmware and that i should connect to the WiFi in order to get the firmware upgrade.

Can’t you update?

Ok. Solved it the following way:

1. Change my router to only have 802.11b

2. Reconnected the L3-5M the usually way

3. The Bluetooth message didappread; the device not connected disappeared.

4. Waited a few hours and eventually it came up with an upgrade available

5. Device now connects without any problems.

Tomorrow I will change the router back to 802.11b/g/n and see if it still be connects without any issues.

The L3-5M is a dud. Due to the use of an archaic microcontroller, it requires you to lower the parameters of your WiFi network to connect, which will adversely affect other devices you connect to it, or to install an additional router exclusively for the L3-5M. In my opinion, it’s best to throw it in the trash and accept that Sonoff has once again let us down…
