Guys, I know this sounds stupid, but try disabling NTP & set date to few months ago. I'm testing something...

Hi @swuggmaister. No I don't have phillips hue. There seem to be multiple posts on this site and other searches with similar sounding problems around this time with the C9 but saying that, also seems to be numerous other models over time with people describing such issues.

With multiple reports on the C9 over these last couple of weeks, is this coincidence or possibly something common a lot of our routers are using/configured with. I was wandering if it had something weird to do with times - as we went into Daylight savings a couple of week ago so my router time was one hour slow but I have added the Daylight Savings hours but still have a few reboots a day. I'm using the default NTP servers: time.nist.gov & time-nw.nist.gov.

@Mendo  It is the same for me... I think you are on to something here. My router was also one hour behind and I changed this, added the NTP server from google and adjusted it for daylight/winter. Still an issue though...

Well i guess i am in the same pool with you guys. It just happened out of the blue after 1.5 years of use. Guess the devices got faulty. Not very optimistic about a soft fix - might need replacement and as it seems TP Link support does not help. I am definetly going with another brand 

They send me "beta" firmware - same version, different rel number and date from 04.2020. And what? Nothing has changed. Router restarted wifi few times and at the end of the day whole router crashed/restarted. I'm tired and exhausted. Probably need another rooter because I can't relay with my calls, cloud services and everything else on this crap.

And believe me or not, but this must be software related. It's almost impossible, that so many routers are doing this in same moment.

@dmk 

Could you please upload the firmware somewhere ?

@Tudorct 

It's not working - tested. Same behavior, same version.
