Slow speeds since I switched to fiber with the XR500.


Recommended Posts

I pay for one gig internet speeds, which I was getting at my old apartment with a coax modem provided by the ISP and xr500 setup. I recently moved and still pay for the same service. However, I now have fiber running to the apartment, and an Optical Network Terminal installed, so I no longer have a modem. After the technician installed everything, he sent me a picture of the speed test results showing 1000/1000 on his end.  The max speeds I am getting are 90/90. I've already done a factory reset multiple times, ran the setup wizard speed test, and disabled Qos. Is there something else I'm maybe missing? Attached is the speed test the ISP technician sent me.

All my cables are cat 6. I even replaced them to make sure none were damaged. I was getting gig speeds a few weeks at my old place. The only thing that has changed since then is now I'm on fiber. I'm not sure how to deduce if its a settings issue with my router or botched fiber install.

It's most likely a auto detect issue. For 1000M you need all 4 pairs and 100M uses only 2. So if signal strength is low on one of the strands for whatever reason it negotiates at 100M. This can be a faulty cable, or even a faulty socket or port at your router. Sometimes even a compatibility issue. You can't force a link speed in the router so it's definitely not a settings issue.

 

Some things you can do. If you have a gigabit switch, put it in between the router and the wall socket and see if anything changes. Ie if link speed on your XR500 increases to 1000M but your speedtest still shows 90Mbit the wall socket is likely the issue. Or vice versa, if you can see link speeds in the switch, and the link to XR500 is showing 100M then most likely the port on the XR500 is the issue. Or it all works correctly, in that case it's an issue between specifically the ONT and the XR500.

 

Something else you can do is plug a PC/laptop or whatever in the XR500 WAN port and see what it does in the XR500 menu (access it over wifi if you must) you won't have a valid connection but the menu should show you the link speed when the cable is connected. 

 

It's not clear to me how the tech did his speedtest. Was that done with a router supplied by the ISP? If so. Plug that into the wall socket and connect the XR500 WAN to that and see what you get.

To rule out the cable being at fault, switch the LAN Port 1 ethernet cable with the WAN cable and see if the Link speeds update to reflect this change and then do a speed test via wifi or using the LAN 2/3 port devices.
