Slow ethernet problems

[Pjanoo]

Hello all, this is my first time posting here so I apologize in advance if I violate a rule. My problem is: I have a Ethernet cable from my router to my computer and its slower than the wireless. I also have a wireless extender in my bedroom and when i plug my Ethernet cable into my main router the name of the network is the name of the wifi booster. I tested my router using my phone and 5G wireless and got around 125 Mb/s. When I use the Ethernet cable its around 10 Mb/s. Im not sure what's happening here but I know that the wired connection should be faster. Notes: ( The Ethernet cable is 100ft cat 6 cable.)

Get a new cable and use it -- does the problem persist?

Also: Is your cable near anything that might cause interference like lights, generators, etc.?

Can you show us how everything is connected in your room? Any cheesy drawing will do as long as it is accurate.

It's weird that you get the network name of the wifi booster. Go thru and double check you router settings.

Thanks. I went into the router settings and my main router was only set as a router and not as an ap connection so it would use ethernet and wireless. The ethernet speeds are around 200 mb/s now.
