Cannot connect to some websites
Hello, I just bought a new TP-Link Archer AX53 router. I replaced an old TP-Link Archer C6 router that worked well, but I wanted to upgrade to better WiFi and WPA3 support. Today I connected the AX53 to my home network, followed the quick setup steps, and the internet started working. Right after I finished the setup, I mentioned that all "http://" web pages stopped working. I thought it was a security protection on the router side, but after that I found that I couldn't load some "https://" pages. For example: https://www.gigabyte.com. I can't even ping this site.
I also noticed that my computer periodically loses connection to WiFi and it recovers after a few seconds.
I can confirm that I didn't have such problems with my old Archer C6 router, it worked for me for many years and always worked stably.
Is there a solution to this problem? If not, I will be forced to return the router back to the store, since it does not work stably.
