Ethernet much slower than the wifi
We have been dealing with this problem for a while. We are on the 1000mbps plan and we are getting 400mbps on wifi and only 90mbps on ethernet. The pc that is hooked up to the router we have taken to the shop recently and everything worked fine and connected to the ethernet just fine. We have also replaced the ethernet cord and updated our router to the newest one and tried all the ethernet ports. Is there something that we are missing?

Do you have a combination modem/router (e.g., an Xfinity XB7 or XB8 cable modem & router) or a separate modem and router (e.g., an Arris Surfboard SB33 cable modem and Netgear Orbi router)? What is the rating of the Ethernet cables from the combo modem/router (or from the modem to the router and then from the router to the PC)? All cables should be rated CAT 6 or better. CAT 5e cables may work if they are of good quality (and the cable is not too long). CAT 5 is not likely to work. The rating should be physically stamped or imprinted on the cable itself.
How long are the cables running from the router to the PC? The limit for CAT 6 is technically 100m (~328 ft.), but I personally won't go more than 50 feet without using a switch in the path. Is there anything that might be electrically noisy along the path (e.g., electric heater, fan, refrigerator)?

Missed something? Maybe. Looks like the bot ate a post for @NoGoodNamesLeft4Me , so I apologize if it was suggested, but for the Ethernet connected PC:
Are you using an anti-virus VPN or other type of anti-virus WebShield/Proxy? Perhaps switch it off temporarily just for the speed test. (encryption overhead, more hops to the anti-virus gateway network, load balancing, DNS lookup lag at the anti-virus provider...etc).

I was having the exact same problem. I was getting approx. 60-70 Mbps wired and 600+ Mbps wireless. I have the 1.2 Gbps plan. For the sake of brevity, I'll skip all of the unsuccessful steps I took to troubleshoot the problem (including an Xfinity tech coming to my house and working on the issue for a few hours).
Bottom line: I switched from a Cat 6 cable to a Cat 8 cable, and my speed jumped to 900+ Mbps. Yes, you read that right. From 60-70 to 900+ just by switching the stupid cable! Some will think a Cat 8 cable is overkill but I've been reading bad things about Cat 7 cables. I went with a 3 ft. Ugreen cable from Amazon.
I always overlook the simple fixes since they are usually a waste of time but, in this case, for me anyway, it worked.
