I'm having trouble getting IOT devices to connect to wifi. I'd previously put it down to "one of those things" the first time it happened (Broadlink remote control) but have since had trouble with some bulbs and most recently a wemos ESP8266 board. On the wemos, I can at least see what is happening. The board can scan for wifi fine and shows that it sees my network. But I can't connect no matter how long I wait.

I'm now wondering if there is some setting in my wifi that disagrees with (cheap) wifi chips on these IOT devices. Originally I had one network with band steering but did set up a dedicated 2.4 GHz network to see if that was the problem - didn't help. My wifi is via Cambium E400 WAPs, so I've certainly got plenty of settings to choose from!

@michaelmurfy - I know, I know. Another reason to upgrade to Ubiquitis!

Lower 2.4Ghz channels... A lot of cheap units don't even do channel 11. Turn off auto and try lower channels (if they're not too congested).

Good suggestion, but it seems to be on channel 1 already:

Channel 1
Channel Width 20MHz
Transmit Power 25
Beacon Interval 100
Minimum Unicast rate 1
Multicast data rate Highest Basic
Airtime Fairness Enable Airtime Fairness [off]

Enhanced Roaming [off] Enable active disconnection of clients with weak signal

Strange this could be what was going on with your Broadlink. Have you got the latest firmware on the AP's also?

I thought so, but having just checked there was another new release in June that I haven't installed yet. I will do that, but I think a factory reset is probably in order too.

You have gone through the process of ensuring

- no symbols in the network SSID or security password

- tried forcing each security type starting from WPA2-PSK AES (best) to WPA-PSK AES or TKIP (okay) to WEP64bit (bad) to none, and not using WPA/WPA2 both mode?
