I just switched Internet Service Providers from one that offered 300Mbps fiber to another, and I'm facing an issue. With my old ISP, I consistently got around 300Mbps on both Ethernet and Wi-Fi. Now, after switching, my Wi-Fi is still clocking in at about 300Mbps, but my Ethernet connection is stuck at just 100Mbps.
I'm using the same laptop and the same Cat6 cable that previously worked fine for 300Mbps. My modem is a ZLTG3000A, which is a Wi-Fi 6 modem. According to the specs, its Ethernet ports should support speeds of 10/100/1000 Mbps, so it seems like it should be capable of gigabit speeds.
Anyone have a clue why my wired connection is limited to 100Mbps while my wireless connection is running smoothly?

Have you tried a different Ethernet cable? Even though you’re using a Cat6 cable that worked before, it’s worth checking since sometimes cables can get damaged. Just a thought, but that could be the issue!
You might want to check if all the Ethernet ports on your modem actually support gigabit speeds. Some modems only offer one 1G port for backhaul while the others are limited to 100Mbps. Just because the modem specs say it supports gigabit, doesn’t necessarily mean all the ports do. Also, make sure everything you’re plugged into can handle 1G as well!
Thanks for the tip! I’ll take a closer look at the port capabilities.
That’s a good point! Double-checking the ports is a smart move. Sometimes the documentation can be misleading.
