EX2700 sudden failure
So I have a C7800v2 modem/router and two EX2700 extenders.
They have worked flawlessly for about 8 months now.
Yesterday, I was going to fire up my grill (it's wifi enabled..) and i loaded the app and everything was fine, and then about 10 minutes later, I checked the app again and it was disconnected. (the grill was linked to an extender)
my connection is solid and stable at my modem, I have two desktops connected with cat6, and multiple devices on the wifi and none of them have been affected. The "router" led on the extenders wasn't lit up, so something broke their connection..
I unplugged them both and went through the factory reset process with each, one at a time, multiple times. I tried both WPS and cat6 cable. each time I am able to rename the extender, but it cannot connect to my router.
did I have two extenders fail in the exact same way at the exact same time? or is there something I'm missing here?
no updates were made, no power surges in the house, no physical movement of the devices. They just suddenly stopped working at the same time.
try setting the C7800's "up to speed" for the 2.4ghz down a notch.

Is the C7800 broadcasting 2.4ghz signal?
Have you rebooted or reset the router?
Any other devices having issues connecting to the router?
running both 2.4 and 5ghz, using WPA2-psk[AES] with no other issues at all for any other devices. just the extenders.
the extenders can see it, but can't connect to it. same passphrase, i've quadruple checked it, during the many factory resets. and access control is disabled, so it's not a blocked MAC address or anything like that.. in fact, there are no devices blocked in the router.

alright, I was 100% skeptical and didn't want to do it, but setting the 2.4Ghz to "up to 433Mbps" did in fact work at getting the "router" led lit up again on the extenders...
just set it back to 1000Mbps and they seem to be staying lit for now..
Thank you all!
Glad to hear it worked! if you mark it as solved it can potentially help the next person with this issue
