I'm having issues with limited speeds with Nighthawk XR500
Hi. I recently bought an XR500 router from Amazon. Before this, I only had a 100 Mbps router. My ISP plan is 300 Mbps. I configured my router with all the default settings. However, I'm having an issu...
- May 17, 2021OK. So, the issue has been resolved. The lineman from the ISP brought in a Gigabit router and tested the main line coming directly from outside from the ISP and it worked. We went back and tested the main line to my router and that also worked. The main line Cat6 cables are perfectly fine. My router is perfectly fine. The internal wiring Cat6 cables of my home are also perfectly fine. The issue was with an RJ45 coupler that was connecting the main line cables with my home cables. He removed the coupler and the two RJ45 ends and directly connected the wires together. Not sure why it was the coupler. I use the same model coupler in a different part of the house and it works fine. Maybe something inside got busted. But now it's back to the desired speeds. Thanks everyone.

I actually don't know what modem is connected to it. There is a junction box installed by the ISP in a nearby house from which they send a cable connection to multiple house. They recently put in a Cat6 cable between that junction box and my house as per my request. That's the line that connects to my router and is spread to all the devices in my house.
Can I still rule out the router being at fault here? The lineman from the ISP keeps insisting the router is the problem and tells me to return it and get a refund. Which I really can't and prefer not to do.

Your caught in a catch22.
It could be the modem, it could be the line, it could be the router.
If you only have access to the router, you're limited in what you can test.
do you have an old gigabit router you could connect and see if it gets a gig connection?
- WDRKKSMay 15, 2021TutorI don't. But the lineman said that he will try to find one to test it. You still think it could be the router? Without knowing for sure, are you able to say what possible causes it could be if it's the router?

Simple cable(+port) test: Connect an unknown cable between two
(known-good?) LAN ports, to see if the cable's good. Both LAN-port
port-status LEDs should indicate a gigabit/s link speed.Simple (cable+)port test: Connect a known-good cable between one of
the router's LAN ports and its WAN/Internet port. Does the LAN port's

Based on what?
- WDRKKSMay 15, 2021TutorBased on nothing. He exhausted his list of solutions so it has to be the variable that's out of his control, according to his logic. In any case, I'm gonna take his words with a grain of salt. Until it's proven with another Gigabit router.
As for the test, currently, in its normal setup, all LEDs are lit up white. I'm guessing this means they are all at Gigabit link speed. Even the WAN port. I can still test and see, though.
