2.4 (B+G+N) but its still not working. A solution would be really helpful.

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. When I tap on the “Got It” button it moves me to the Wireless Settings. However…

I am having the same issue which irritates users. This debugging message keeps popping up:

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.
