Thanks for the update info.

1) "Instant Guard" still does not work. I updated the certificate and restored the factory settings.
2) After several hours, disconnects the connection with the dropbox.

As I had the software Version 3.0.0.4.386.42643 everything worked

Let us know your network setup?
Is your router connected to a Gateway or a Modem?

Hi.
- Router connected to the modem (wired network)
- a disk connected to the router
- I use AiCloud 2.0 and Cloud Disk

I know you said that it worked before, however, there could be other things lurking in the background waiting to show their true selves. That being said, your Fiber modem has two functionalities:

It can act as a router with NAT
It can act as a Bridge with no NAT

Can you find out what mode your modem is in (router mode or bridge mode)? Do this by logging into the modem's web interface. BTW, your modem is basically a gateway device.

I cannot log into the modem - I got a modem from the cable Internet provider.
I also have my own permanent WAN IP address.

The router is in NAT mode

Do you have any idea to solve the problem
I would like to add that the speed test built into the router does not work either.
Speed Test works via a web browser.

Different issue, same firmware.
I am getting disconnected every 15-20 minutes. The connection simply goes away then a couple minutes later the WAN light goes red, then white and connectivity resumes.
My home has extremely high data volumes (40+Gb /day), mostly Twitch inbound and youtube. There's also a lot of Teams time on weekdays. Add a lot of IOT gadgets, phones, a couple of TV's, consoles. Usually 25+,sometimes 35-36 devices.Will b more when family visits. Doing DMZ, forwarding, QOS.
ISP equipment is Arris gateway, not bridged, 1Gb service. It indicates service uptime 45 days. Router has static IP reserved on gateway
The March 17 update ending 46092 had a similar problem, but much worse so I had rolled back to 42643 until 48377 came out.
Worked rock solid reliable on 42643. Can't roll back because of the security issue (can't recall name)
Please help
