ZyWall freezes. Only a power restart helps

TeddyRipper

Hello. I have a ZyXel ZyWall 110 installed, it has been working for several years without problems. Suddenly it started to freeze, at the moment of freezing the local network, the Internet stops working (sometimes the RDP connection does not break). If I disconnect the network cable, the indication on the port remains (the orange indicator is on without blinking). Only restarting the device by power helps. The problem recurs 2 or 3 times a day with an interval of 5-7 hours.
I checked the local network and PC, this is not the source of the problem.
Firmware Version V4.62(AAAA.0)
Please advise what can be done in this situation.

@TeddyRipper Your device may encounter this

Please upgrade to the latest firmware version v4.73P2 and check if this behavior still exists

from version 4.33 immediately upgrade to 4.73P2?
How to do it (I updated via FTP)? And for what?

Just upgrade directly at once if you don't have complex settings inside. Remember to backup your settings before doing so

Updated. It's been two weeks since the update. Everything works great! Thanks for the help! :)
