I signed up for 25 USD a month with 300 Mbps . Speedtest reported only 80 Mbps

I signed up for 300 Mbps package last week. Since connected and activated, the speedtest reach only 80 Mbps maximum. This has been test by hardwire, isolated all other devices, using my mobile, using my laptop , using my colleague laptop. 

Online support system kept taking me through infinite loop to troubleshooting the devices. There is no issue with the devices .

I am using an Arris Modem SBG8300 3.1 which support up to 2000 Mbps , it is only reach 80 Mbps which i believe limited by Xfinity.  

Anyone know how to resolve this issue?

TPham6886 Hello there. Thanks for reaching out to Xfinity Forums! You have come to the right place to get your internet speed concerns answered. When testing speeds, we always ask our customers to test their device using an Ethernet connection. This gives a dedicated line of speed directly to the device. Testing internet speeds via WiFi can make your speed flucuate due to a number of different factors.

Yes, early day I worked for Cox Communication and Time Warner Cable , and well aware to do that. "This has been test by hardwire", meaning only test with Ethernet cable. The speed is the same. At the same time, infinity system should be able to see the modem upload and download connectivity health.

TPham6886 I appreciate you clarifying that for me! Have you attempted to use the self-troubleshooting option located in the Xfinity app? If not you can find those instructions here https://www.xfinity.com/support/articles/internet-connectivity-troubleshooting.

Hi Brian, Thanks for the troubleshooting steps. I have followed it and nothing changes ? if the speed is this bad in the neighborhood and nothing Xfinity can do , are you suggesting I should cancel Xfinity and goes with other supplier ?
