XR500 very slow download speeds only to PC
Hello everyone,
I recently purchased a CM2000 modem and XR500 router. Upon installation I performed a factory reset on both devices as well as verified that they had the most recent firmware. MY ISP speed package is rated for 1 Gbps but for some weird reason I am only getting 30-50 Mbps down and .71 Mbps up via CAT 8 cable.
I tested my PS5 via CAT 5E on each port and I am getting 820-900 Mbps down and 110 Mbps up. I also tested a macbook wired and it was receiving around the same numbers as well. After contacting support about this problem, they asked to check my network connections settings and I verified that my ethernet network speed was showing 1 Gbps.
The first tech told me that my ethernet port on my motherboard was possibly damaged and recommended I should buy an USB to ethernet adapter. I luckily found one and used it but sadly I still am receiving the same numbers. I called them back but they told me I have to contact ASUS before they can further assist me -_-.
The same PC was working fine with the previous router (R7000) and with that equipment I was getting 800 Mbps via CAT 5E. Any insight and advice would be deeply appreciated. Appreciate your time in reading this.

Update: I bought a Netgear AXE3000 WiFi adapter and my speeds went up to 70-90 Mbps down but stayed at .70 Mbps up. So it's confirmed that either wired or wireless my connection is still the same. Which leads me to believe that it's not the PC and rather the router or settings within the router.
First test the PC with the CM modem directly with the PC. Does it get to spec speed there?
Is QoS enabled on the XR router. Speed test with QoS disabled.
Also be sure to speed test with Ooklas installable speed test app on the PC.
What is the brand and model# of the ethernet adapter in the PC?
Be sure the ethernet drivers are up to date from it's Mfr.
Test with different cabling. CAT6 Is recommended between the modem, router and PC.
What FW version is loaded on the XR500?
Hi Furry, thanks for the reply. Is e38 a bimmer reference?
Anyway, I tested the modem directly to the PC and confirmed 1 Gbps
This is what it looks like with the wifi adapter
As for the router everything is set by default except for SSID. I have only been testing on speedtest.net and here are the numbers:
Wired w/QoS: 16.53 Mbps down / 0.26 Mbps up
Wired w/out QoS: 17.70 Mbps down / 0.29 Mbps up
Wireless w/QoS: 56.43 Mbps down / 0.41 up
Wireless w/out QoS: 43.63 Mbps down / 0.29 Mbps up
The brand of the ethernet adapter was Realtek. Although I switched to a Netgear AXE3000 WiFi adapter to rule out certain things. The driver for the AXE3000 was updated to the latest FW as well. I tested with different CAT 5e cables plus the CAT 8 Cable that was used for the results above. When you said CAT 6 is recommended, a CAT 8 wouldn't be better and the best cable for XR500 is CAT 6? Lastly, the FW on XR500 has the latest FW installed.
Yes.
What speed results did you see with the PC ethernet connected directly to the modem?
- Where are you checking the speeds, on the router itself or on Ookla? Have you set the speeds you expect on the router itself? Go to the Device Manager and switch to the table view and check the link speeds of the ports. It sounds to me as though some of the cables may be limiting you.
Hi Fraser,
The speeds I have been posting were from speedtest.net
I set the bandwidth speeds to 1000 Mbps down and 200 Mbps up for recent test results. As for the link speeds on ports its showing 1000Mbits, Full duplex.
- Copy the MAC address of the previous router you were using and set the XR to use that instead, then reboot it and test the speeds again please
