For the problem that loss internet, did your PC has IP address at that time? If not, maybe you can try to set up static IP address even static ARP, check if can solve the problem. For the web GUI change, maybe you can try to clear browser cache.

 

If the above way has not any help, suggest to ask tp-link support for help.

Thanks for your suggestions. My PC had static IP address and couldn't see any communication to "dead" port. Re-plugging cable to other port which was not dead allowed further communication as usual. However dead port(s) could be brought alive only with the switch reboot.

 

Regarding GUI change, I tried different browsers, clearing cache. IMHO anybody with that switch can test it and will have same results - it is in the firmware.

I can confirm that my switch is still working properly since I've changed its IP.

 

I am suggesting tp-link support to have a look at this "feature", it should be easily reproducible. I will contact them.

Support case is open, support team is great, testing the switch, but the issue cannot be reproduced.

I am also trying to reproduce the issue, however even after resetting to defaults the issue cannot be noticed.

So I am testing and waiting if "dead ports" occur again. If not, then it was some kind of weird behavior that is "fixed" by couple of reboots, resets and IP changes.

Or something specific in my home network that disappeared. I am really confused.

I will come back here if I have some news.

If you can found the cause, you can share here. I am also curious about how can make port dead. But if your network can work normally all the time, it's also a good thing.

@Jan_Kab

issue never came back in another 6 month of usage, assuming no problem with the switch.

I do expiriance the exact same problem now!

 

Can You please specify the steps You took to get rid of the problem? Rebooting (Wie WebGui) did not solve the dead ports. What else to try?

Greetings !
