My A7 (also running FW 1.1.4, build 20211022 rel. 58866 (5553)) started dropping the internet this morning after many months of being stable. Strange that this started out of the blue.

 

Rebooting the router resolved the problem for a couple hours and then it dropped again. After the third drop, I checked and found that there was a newer FW release in March 2022:

The release note doesn't describe my problem, but I updated anyway. Hopefully this will stabilize my connection. 

I have a similar issue. 1.2.0 Build 20211210 rel.56314(5553) Ever since I upgraded to this issue, every few days I have to reset the router. Various symptoms. - wireless won't connect - ethernet won't connect Since those are the main issues I don't know whether it's connected to the internet or not. I guess I will try this March update even though it doesn't show up as "update available". Thanks!

 

Oh, well I guess this IS the latest update, referred to by the previous poster.

 

Maybe it's time to look for a new router.

I got onto support chat with TP-Link. Checked my DNS settings, I had them "set from ISP" and they were 75.75.75.75. I was asked to set these to 8.8.8.8 and 8.8.4.4. My symptoms don't match their expected "can't connect to internet" scenario which is what the tech seemed to be trying to match. To be honest, when the problem happens I can't tell you whether the router is connected to the internet or not because I cannot even connect to the LAN. This morning at least when I checked, the internet LED was not orange. One LAN port was dark, but perhaps something was unplugged (power goes off relatively frequently and when it happens I shut the UPS supplying some other devices down).
