Disconnect on New DHCP Lease Allocation (Ethernet)

So this issue has been going on for literally since I bought this router, 8 months ago. Every single time my router needs to allocate a new DHCP lease, which for some reason is every 24 hours because you can't change it, my internet disconnects.

This is a GAMING router. It is absolutely ridiculous that it disconnects every single night every 24 hours because, I assume, it can't do what every other router does and renew the lease ahead of time before it needs it. The disconnect is milliseconds long, but for whatever reason I am always consistently forced to literally restart any internet-connected game after the lease renewal.

I have already tried several things to fix this issue. I have updated to the most recent firmware, 2.3.2.32; the firmware update that CLAIMED to fix a "disconnect issue," which I can only assume is this exact issue because so many other people have complained about it. Didn't work. I've tried disabling Smart Connect in Wireless Setup, and that also didn't work. I tried using Static IP allocation, and instead of just a quick disconnect and reconnect after the lease expiry I just couldn't use the internet at all anymore. I read that you can disable MIMO or something like that, but I don't even know what that is ("[something] In, [something] Out?") so I can't try it. My MTU size is already optimal based on the ping test so changing that won't do anything.

You can probably tell by my incredibly passive aggressive tone how frustrating this problem is, and I'd like to know if there are any solutions in the works or if there's something I'm not doing that works to fix it. This is pretty unacceptable for a router called a "pro gaming router."

EDIT: I tried a factory reset. I've been disconnecting predictably at the same time every day but I won't be around tomorrow night during the normal time so I guess I'll report back in 2 days to see if it worked.
