Super slow download and upload speeds on my XB8 modem

[aa2738]

Purchased a new plan,2.5GBPS download and upload speed. I set up the internet and run a speed test near the router i get 500-600 mbps download and 80-90 mbps upstairs. now i installed the wifi pods and connected to ethernet to my pc and i only got up to 100 mbps download, which is really bad, i contacted support and i tried all their steps and still didn’t work,

@aa2738  What results do you get when you perform a speed test using the Xfinity app?  For information on how to do this, go to: https://www.rogers.com/support/internet/speedtest

And ..... is your XB8 connected via RG-6 coax cable or via ethernet to a Nokia Optical Network Terminal which is used in Fibre to the Home installations.  The Nokia ONT has to be connected to the XB8's port #4 (lower right hand port), which is the only 2.5 Gb/s port on the modem.  That connection to port 4 is also required as its the only autosensing WAN / LAN port which is firewalled.  That firewall is required in FTTH installations where the WAN port on the modem is thru port 4 instead of the cable port.

In the case of FTTH installations, with the 2.5 Gb/s port occupied, that leaves ports 1 to 3, which are 1 Gb/s ports.  So, in this configuration, you can't get 2.5 Gb/s thru the modem to a downstream device, via ethernet.  Comcast is coming out with a modem which has 10 Gb/s ports, (don't remember if any of the LAN ports are 10 Gb/s), so, one can assume maybe summer 2025 to make an appearance in Rogers networks ??  Or possibly 2026.  Rogers has already been testing a high speed modem in Calgary, but, there hasn't been any news out as to its success, or not....

Hi, My XB8 is connected ethernet to a Nokia Optical Network Terminal with the fibre

Ok, are you also running the Ignite TV service, or just running the internet service?

Note that you can replace the modem with a router, preferably a router with multi-gig WAN and LAN ports so that you can run 2.5 Gb/s out to a device or a multi-gig switch and then out to your devices.  Ignite TV adds a wrinkle to this due to the services provided to the set top boxes via hidden wifi network.  Without Ignite TV running, replacing the modem with a multi-gig capable router should be easy to do.  That would also give you control over your wifi network, instead of Rogers backend systems running your wifi network.  

Right click on the network symbol in the lower right hand taskbar and select Open Network and Internet Settings.  Select Properties for the network that you're connected to.  That brings up the network page.  Have a look at the Link Speed (Receive / Transmit).  That will show the raw connection rate, either ethernet or wifi if you happen to using a laptop.  If you're using a laptop, take a walk around your house, stop in place where its appropriate and let the Receive / Transmit numbers settle out.  Those numbers are dynamic, and will change with the distance to the modem, which changes the received signal levels and signal to noise ratios.  Those two numbers will determine the received data rate at any given location.  By taking a walk around the house, you might be able to observe where the modem kicks the device from the faster 5 Ghz network to the slower 2.4 Ghz network and vice versa.
