I've just moved into a new house and originally had all my devices directly connected to the modem with great speeds—in the range of 500-600 Mbps. However, I noticed my new home has Ethernet wall ports in all the rooms, so I switched and plugged everything into those instead. Now, I'm only seeing speeds around 80-90 Mbps. What could be causing this drop in performance?

It’s possible that the wall jacks are only utilizing two pairs of wires instead of all four, which would cap your speed to around 100 Mbps. If you can, open up the wall plates and take a look at how everything is wired. It might be worth getting a cable tester to check if all connections are correct.
Make sure all four pairs of your Ethernet cables are terminated properly; if even one wire isn't connected right, it could knock your speeds down significantly. If you have pictures of the wiring setup, that could help diagnose the issue.
If you're seeing those speeds, check the patch panel and the switches you're using. Old equipment can be the bottleneck, even with new cables. Running Cat5 can limit you to 100 Mbps, so if you've got a mix of old and new equipment, that might be causing the slowdown.
The issue might be how those wall outlets are set up. If they lead to an old switch or hub, that could limit your speeds to 100 Mbps instead of the full potential. Check if the outlets connect directly to your modem's patch panel or if there's something outdated in between.
