Paying for 1.2Gps Xfinity plan only getting 250Mbps
Recently changed internet speed from 1.0Gps to 1.2Gps, but only getting around 250Mbps at the PC. PC is custom built with a 2.5Gps ethernet Intel card/port. New G36 DOCIS 3.1 modem (Xfinity approved) Tp-link 10Gps router with 2.5Gps ports. Just had the Xfinity Tech out here 12-28-2022, tested the line from street - he was getting 930Mbps+ on his little meter device. While he was on-site, we tested side by side from the modems 1Gps ports, and from Xfinity speed test website - he was getting 900+Mbps, while I was getting just 200Mbps. Just doesn't make sense. Every piece of network equipment I own is capable of over 2.5Gps; including CAT6 cables. The runs are less than 50 feet with no other connections. Fun fact, on 12-24-2022, I hit 1.4Gps, but just that one day, 12-25-2022, back to 250Mbps. I prepared a table below to showing my speeds since switching to 1.2Gps

The manual I was looking at for the G36 has a 2.5Gbps port. What's it doing?
■ Green: LED is ON: Indicates a data transfer rate of 2.5 gigabit per second
■ Green: LED is Blinking: Indicates data traffic is in progress
■ Amber: LED is ON: Indicates a data transfer rate of less than 2.5 gigabit
per second
■ Amber: LED is Blinking: Indicates data traffic is in progress
Have you tried just hooking up the PC to it to see what you can get? reboot PC and G36 to get a connection. If that looks legit, the we start troubleshooting the TP link.

Hi Flatlander,
Yes, I have also read the manual. I have a GREEN led indicating a 2.5Gps signal.
I have used my MSI laptop (capable of 2.5Gbps) hooked right into the G36 modems 2.5Gig port, bypassing everything, and STILL 300Mbps, approx. The TP Link is a AX16000 with 2 10gig ports and 2 2.5gig ports. The 2.5 ports are hooked up directly to my desktop and my Xbox. https://www.tp-link.com/us/home-networking/wifi-router/archer-axe300/
The modem has been rest from the Xfinity website and by a tech.

A lot of those cards/adapters need the drivers from the actual manufacturers website not the plug and play ones..

OK, fair enough. But when I look for issues, I start at the 1st connection and remove aux hardware that may have non-optimal, irrelevant or downright conflicting settings. LAGG enabled with non-LAGG hardware isn't helpful as an example.
If you are only getting 300Mbps at the G36, it's not going to get any better at the TP-link. Try any of these?

Specifically, what do the signals look like? Power up/down stream/snr/errors. Any log messages (you'll have to redact MAC addresses or the bot will flag it private). Got splitters to a cable box or an amp? Might need a wrench for a test :)

Personally if I have issues, I boot into Linux, all the same hardware and connection, and see what I get there, if I get the correct speeds I can usually point the finger at windows..

Additionally there might be a setting on your network card that allows power saving, I always uncheck the box, less power = less performance, on my card there is a setting, green Ethernet, power saving, I don’t want any of that so I disable it all, if you screw up, just uninstall the card reboot and your back to default settings, just a thought..

Regedit for TCPIP hardware/software checksum offload, or perhaps that would be in a driver interface -- if the driver package has one or a gui too. It's not helpful sometimes. Try Linux first.
