I added a USB hard drive to the router USB3 port yesterday and setup AIDisk to access it via the internet or my LAN.

I get this message when trying to access my router from my wired connection: "Settings have been updated. Web page will now refresh. Changes have been made to the IP address or port number. You will now be disconnected from RT-AC66U_B1. To access the settings of RT-AC66U_B1, reconnect to the wireless network and use the updated IP address and port number." I don't know what this means. I can't reach my modem config page from the wired connection

I can access the router and modem from my wireless connections but I don't know what to do once I get into the router.

Help! :)

Some updated info. It appears I can access ipv6 connections with my wired computer but not ipv4. When I check ethernet status of my adapter, ipv4 says"no internet" and ipv6 says "internet". When I try ipconfig /release or /renew, I get the following error message: "An error occurred while releasing interface Ethernet 3 : The system cannot find the file specified." The IP address from ipconfig shows: Autoconfiguration IPv4 Address. . : 169.254.205.127(Preferred) but the DNS server is 192.168.50.1.

I decided to try assigning a static IP address to my desktop. That screwed up everything so I deleted that. Finally I just removed the USB portable hard drive from the router USB3 port. I also updated the firmware. Now everything is working fine.
 
What's the size of the disk you connected?
Have you perhaps tried a completely different disk (different size, make, etc.)?
I'm asking because when I had the Asus RT-AC86U, I had great success with two enclosures like such - https://en.sharkoon.com/product//16310. Provided however that I didn't use HDDs larger than 2 TB; if I did, the router would get 100% CPU spikes and I wouldn't be able to log on.
But later, when I switched to the TP-Link C4000, I couldn't use these enclosures at all, no matter the disk size - one of the four cores would go up to 100% CPU usage and stay like that forever.
And here's the kicker - I can use practically any WD drive (tested up to 10 TB capacity!) without any problem whatsoever on the C4000, just not the Sharkoon enclosures.
Hence my questions ...

It was a 750GB WD Elements USB3 portable hard disk. I don't have another one to try and it's not worth the hassle to fool with it any longer. It's easy enough just to plug it into a USB3 port of whichever computer I want to use it with. Thanks for the info.
 
Your decision of course, but I would still try out a different disk.
From my experience, older small-capacity HDDs like the one you mentioned tend to have issues, and not only with routers.
