XR500 Limiting 100MB to Ethernet Ports

[CMXR5001K]

Hello,

For some reason, my XR500 is limiting my download speeds to 100mb on my ethernet ports, and my wifi. 

It was not doing this a few days ago, this just started out of no where.

I have a comcast CM1000 modem, with 1gb internet download speeds.

When plugged directly into the modem, I'm receiving 800+/- on the download, and 30+ on the upload.

I have tried disabling QoS, still no change.

Any help is apprecaited, thanks.

Sounds like you may need to change your cables, if you try a new one does the link speed change back to 1000Mbps?

[CMXR5001K]

No, changing the cables does nothing. I’ve tried multiple, brand new cat 7 cables.

This is also a new issue, it was fine a few days ago, nothing has changed.

It's also not just the ethernet, it's limiting the WIFI as well to 100mb

Did you replace the ethernet connecting the router to the modem? As that is the one that would also have an affect on the wireless speeds.

Have you tried going in manually to set the qos for gigabit speeds? 

A tried a simple factory reset on the router? 

what firmware is currently on the router?

[CMXR5001K]

Yes.

[CMXR5001K]

I've tried changing it manually to 1000/1000 Yes, nothing changed, and I've disabled it all together, nothing has changed.

I've factory reset the router twice so far, no changes.

It's currently on V2.3.2.66

Do a factory reset and setup from scratch and see if it works properly then.

[CMXR5001K]

I've done that, three times now.

Reinstall the firmware via TFTP and then do a reset, that will bypass the boot process and any issues there and give you the freshest install possible https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP
