After Successful pairing and Renaming the device it does not connect to wifi and Green light keeps blinking, tried to delete and repair but no luck.
One device is connecting and another - Does not.... :(
I had the same problem that I solved in the following way (I'll tell you step by step in case it has a meaning):
after trying all the way at first i disabled the 5ghz wi-fi: nothing happened;
then i forced the wi-fi to use ch7: nothing happened;
then i forced the wi-fi to use the TKIP cipher type mode only: i can pair my sonoff pow!!
I followed back step by step
enabling both TKIP and AES
then enabling auto Ch
then enabling 5Ghz band;
Now it seems to work again
Device pairs and is registered then fails to connect to server.
Tried to delete and pair again but same problem.
I found problem seem everyone.But I unplug it a few day.Today i plug and try to connect it work.I don't know what happen about its.
Also experiencing this issue with First Gen Sonoff Basic's.
I have more info to add. I upgraded our router, and none of my sonoff basic's would connect to the new wifi.
I tried every combo of settings with no luck...
I set my router back to the right settings, and pulled out a new sonoff basic and it connected with no issues.
My first thought was a Firmware bug. The installed units are upgraded to v2.6, and the new one was still on v1.6.
I upgraded the new one to matching firmware v2.6. Deleted, and was able to resync with no issues.
The existing units still will not connect.
I think it has something to do with the ewelink/itead network caching the device id's ?
I don't think, i try to sniff the traffic and the sonoff device don't respond correctly when it have to connect.
They start to communicate but at a certain point the sonoff don't respond.
I try with 2 wifi one working the other not.
After some more digging, I've noticed the ONLY different think I can find is the encryption type.
My old wifi was AES, the new one only has TKIP
I was able to make a connection with a basic and Tenda Router...
When WPS is enabled, you have 2 minutes to get to the sonoff switch and get it connected.
I have a just swapped from bt home hub to sky q hub and can only connect one of my 8 sonoffs.
I have split the 2.4 and 5 ghz without any luck and also tried to connect onto a mesh system which also doesn't work.
The units connect via Itead but pairing to wifi they just blink every second
Has anyone successfully connected to sky q ?
