Wifi no network interface after updating firmware to 6.2.4
Hello,
A few days ago I updated my prusa mk4 from firmware 6.1.3 to 6.2.4. The firmware flashing was okay. When it finished it started flashing the ESP and the progress completed. Then started another process about the ESP, something about restoring something with a progress bar that started over when finished (didn't take a photo).
At some point the printer restarted and it was working fine, except for the wifi. When using the network setup option it says "No Network Interface" (see attached photo). On the network status menu it says that wifi status is "gone".
Before the update the wifi was working kind of okay, a bit unreliable. Sometimes it stopped working for no apparent reason but after restarting the printer it usually was fine again.
I tried re-flashing the 6.2.4 firmware but there was no ESP stage this second time, like its not even there, so I'm not sure what to do with it, may it be broken?
When turning the printer on the blue led on the ESP flashes blue once.
I didn't find any related post, got any idea?
Thanks.

I have the same problem after I updated my Mk4 from 6.2.4 to 6.2.6 via Prusa Connect - did you find a solution for this problem?
RE: Wifi no network interface after updating firmware to 6.2.4
For anyone having the same problem:
I got wifi connection back, both on 6.2.4. and 6.2.6:
First I downgraded to 6.2.4 (this was a first - hint: double tap the knob to force the downgrade, the prusa instruction page is wrong in that part).
There I got the same problem at first. I then switched off the printer completely for 30 seconds. After that the wifi was back on 6.2.4.
Then I did the same for 6.2.6.
Here the connection did not come back, instead I got a "no AP" connection status, while my network info seemed to be intact.
But at least "No interface" error was gone. I then reconfigured the network. This also did not help. But an addtional un- and replug of the power did.
I am not entirely sure what the problem is or what exactly fixed it.
My guess would be that the ESP to MK4 communication is in an invalid state after the update and needs to be reset.
Maybe I was not patient enough with the 6.2.6 firmware and the reconfiguration was unnecessary.
