May I know when did you purchase this Archer C7? Does the issue happen when you installed it? It's suggested to reset the router to factory defaults, then reconfigure it from scratch to confirm if the issue persists. Here is the guide to reset it: https://www.tp-link.com/support/faq/140/.

 

When it hangs, are all the LEDs on the router steady on? It will not recover until you power it off then on?

 

There is a NAT and NAT boost feature on the Archer C7 web interface page, I think you are talking about the NAT Boost, you may check if you can disable it to confirm if the issue is related.

Hello Kevin, I bought it roughly 2 weeks ago but out of box it had old firmware from 2019 I patched it to latest possible immediately so I don't know if this issue was also present with 2019 firmware, yes it happens from the very beginning since I installed it.

 

I can and tried disabling NAT Boost but issue happens as well. no matter if NAT Boost is on or off.

I am not 100% sure I will check when next hang occurs but I think all LEDs are same as usual so Power LED is green, 2.4GHZ wifi indicator is green, WAN goes from green to orange and 2 LANs are green, issue won't go away until I power it off and on again I can't even access web-admin 192.168.0.1 when it happens.

 

Yesterday I disabled Mesh mode since I don't have any additional AP or additional router and so far it didn't hang but it's too soon to tell 100%.

If this issue happens again I will try as you suggested and reset router to factory settings.

 

Thank you for your help so far.

Good try, you may disable the Onemesh feature on it to verify if the hang relates. Do try my previous suggestions first if the issue happens again.

 

Good day.

Well, today it happened again, it looks like disabling Mesh mode helped so crashes and not daily but weekly. But they are still occuring. Tomorrow I'll put router back to factory settings but my current settings are 99% default settings anyway.
