This is correct. That appears to be a Zyxel GS-108S gigabit switch. The ports are QoS enabled: the green have highest traffic priority, yellow have medium, and gray low priority. This lets you arrange your network devices to ensure things like media streamers take priority over general web browsing, for instance.
A little more digging turned up this option:

Probably better fit for your needs. Aimed more at home users than the other one, has multiple 2.5Gbps ports, and has wifi built in. Overall would be much easier to work with for you I think.
It’s overkill for what it sounds like you need, but something like the TP-Link ER707-M2 would give you the speeds your asking for, for a not unreasonable price.

2.5Gbps WAN, 2.5Gbps LAN, plus additional gigabit LAN. You’d need to add a wireless access point for your wifi devices, but those can be had cheap. Hook your modem up to the 2.5Gbps WAN port, and your computer to the 2.5Gbps LAN port, and you’ll get max speeds. And you should be able to limit the wifi bandwidth either on the router or the AP, minimizing impact on your wired speeds.
Personally, if I needed 2.5Gbps, I’d invest in a Firewalla Gold Plus, but I just really like my Firewalla Gold.
All that said, I don’t think you mentioned what your provider speed is. Unless you’re getting more than 1Gbps from your internet provider, you don’t need this. Also, of course, your computer would need a 2.5Gbps network adapter, but I assume you have one already (or a plan to get one).
It definitely sounds like a backlight issue, but check the display connector again. I had some weird video problems with my AMD main board when I upgraded, some of which sound a bit like yours. It ended up being a speck of dust or something in the connector. Once I blew that out with some canned air and reseated the connector, everything worked properly. Worth a shot at least.
I went with 11 for the aforementioned issues. Originally wasn’t planning on it, but when I saw that 10 wasn’t supported, and that there were performance concerns with it, I bit the bullet and installed 11. Have been pleasantly surprised by it. Followed the FW guide for upgrading the main board (from my 11th gen), and it went pretty smoothly. No online account needed either (use Rufus to make the boot media and remove that requirement). I may even change my desktop machine over to it.
Incidentally, Stacksocial has Win 11 Pro right now for $25. Cheapest you’ll find it anywhere.
This. If you’re not trying to use the wifi on the 2nd router, and it’s already wired to the 1st one, just replace it with a switch with the needed number of ports. Having a second router can definitely cause problems if the routing functions are still active.
