Devices unable to connect to EX7700 extender networks.

Purchased the EX7700 extender in late March and it's worked great up until last week, when my mobile devices began to get booted off the 5G network with the 'incorrect password' error. It was only mobile devices and 2.4g network worked fine. After a few days of that, desktop devices began to get booted off the 5g network as well, no error message, just kept switching to 2.4g. I reset the router to factory settings yesterday and it seemed to have done the trick, until today. 

 

Today I couldn't connect mobile or desktop devices to the 5g network, which usually happens because the 5g signal doesn't reach my bedroom/office. Kept getting booted and switching to the 2.4g network... well, the whole point of having 5g fiber and an extender is so I can actually use the 5g network in my office. Try to troubleshoot, can't connect to mywifiext, can't connect to my IP address, mywifiext.local says I'm not connected to the extender networks. Well, that makes sense... except it doesn't. Device was just reset yesterday. Check the device, it's powered on, all lights are on. I moved it closer to the router and plugged it back in and it seems that I'm able to connect my laptop to the 5g network no - it's showing up under 'connected devices' when I log in to the router, but I still can't connect to mywifiext. I've tried this on multiple desktop and mobile devices so I know it's not a browser issue. Smart connect is disabled. I honestly have no clue how to continue troubleshooting and am about ready to throw this expensive paperweight with its lack of technical support out of the window. Please help!

What router are you connecting to?
What version of the firmware are you on?
Are you on version 1.0.0.210 of the firmware? 

If so, downgrade to the 1.0.0.206 version, factory reset, and reinstall. After reinstall, disable auto-updates. I've seen a coupe posts where people are having issues on the latest firmware.

I'm having issues after updating to this firmware upgrade as well.  How do I downgrade?

Re: Devices unable to connect to EX7700 extender networks.

to downgrade, you simply go to the support site and download the firmware version you want. 

then follow the manual firmware update process from the manual but use the firmware you downloaded.

Thanks @plemans! I've been putting off the downgrade for... no good reason at all, but have finally made the switch. Hopefully this will do the trick, as working has become increasingly difficult on the 2.4gHz network as my work computer slows down even more due to age.

There is a new version of the firmware that does not seem to have the problems of the 0.210 firmware:
