LAN Ports have different speeds but should all be the same?
Upgraded Internet speed with Spectrum ISP to 400mbps. 2 LAN Ports show amber light (100mbps) and 2 show green light (400mbps?). Two identical desktop PCs connected. One has a speed of 390mbps (green port) and the other 97mbps (amber port). Same NIC in each desktop capable of 1G speed. Laptop connected to the other port displaying amber light and gets 98 mbps. Spectrum confirmed I should be getting 400mbps. The LED lights stay with the cabeling when CAT5 cable switched from one port to another. Laptop on wireless 5G gets 180mbps. I cannot figure out why my one laptop and desktop only get <100mbps. Any suggestions would be appreciated.
- Yes, being able to post problems to a community board also helps me work through possible solutions. Now nice to know that in the case of internet speed an older switch can screw up the speed if it is only capable of 100mbps. I forgot all about the switch since I installed it to split the Cat5 wire between a network printer & PC then hid the switch. Now know for others.

You said led lights stay with the cabling?
you mean when you switch cables from 1 port to the other, that port changes?
have you tried replacing the cables?
- Cables are built in wall. Will run 1 cable to the desktop PC when I can get out to buy a 50ft cable & run directly to PC. Just appeared to be a too much of a coincidence that two cables have the same issue (laptop & desktop) when the 2nd identical desktop operates at 400mbps with similar in wall cabling. Trying to check out other possibilities first. Thanks for your advice.

If you've got a 6ft cable around, you could move the computers to test it with.
