VERY POOR ETHERNET CONNECTION

Hoping I can find some guidance here instead of directly for xfinity as I am starting to feel I am being played..I was recently upgrading to the 600mb speed however, I cannot even get 150mbs connected through Ethernet. I have spent days researching all problems with my laptop and nothing. It is not on my end yet, xfinity claims it is. I had the 200mbs plan then everyone got an extra 100 mbs which brings the speed to 300mbs once I upgraded my old modem I discovered I was not even close to getting the speed. I was sent the new xb7 modem (white one) still, no difference in speed and I tried another laptop and the speed is the same a neighbor plugges his laptop into my Ethernet and guess? still slow as [EDIT].  xfinity claimed it was my pc, I switched the Ethernet cable to a cat8, moved the modem closer and higher up and still the Ethernet is slow as [EDIT]. wifi on my iphone and ipad is getting around 450 - 520 mbs which is good, but my pc only has 2 GHz (ordered a new dual band with 5 GHz), but I need the wired speed of 500 or better not wifi. Anyone have any ideas? tech is coming out Friday Dec. 3. Again, nothing is wrong with my laptop, Bios updated, drivers updated, new coaxial cable, new Ethernet cable as well.

You never mentioned the brand, model, or age of your laptop.

If it only handles 2.4 Ghz, it may not handle the speed.

I did not need to mention the brand, name or year, as I stated in my post I am having poor connection via Ethernet. I am aware of the 2.4 GHz, that applies to wifi speed not Ethernet. I also stated in my post I ordered a new wifi card that supports 2.4 and 5.0Ghz dual band, but that should not affect a hard wired (LAN) connection. Do you have any suggestions on LAN not wifi?

Thank you for reaching out over Xfinity Forums @user_9ea840. This certainly sounds like a unique situation. I am sorry you have been experiencing ongoing problems. I appreciate the details you have provided. Those details will truly help everyone narrow down a cause. It is odd you have been getting good WiFi on the phone and iPad but not through the laptop connected via ethernet. That really tells us we are pushing good speed through the line to the modem. Do you use any device between the modem and your connected laptop (router, mesh system, splitter)?


I am glad to hear you have an appointment with a technician. I would be happy to investigate further from my end.

It may have some bearing on ethernet speeds too as usually an older PC with only a 2.4 GHz WiFi doesn't have much ethernet horsepower either. 

That said. Does the laptop's network adapter (NIC) have a 10/100/1000 (gigabit) ethernet capable port ?
