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 issue where I'm getting only up to 100 Mbps speeds with my connection (realistically around 92-94 Mbps).

I browsed around the forums for different solutions and one suggested looking at the Device Manager to look at link speeds. I have attached a screenshot of my link speeds. I have a desktop connected on port 3 and the link speed is 1000 Mbits. I'm assuming this means the cable between my desktop and the router is capable of upto 1000 Mbps speed. In the INTERNET port, it says only 100 Mbits. I'm guessing that I'm only getting upto 100 Mbps through the cable from the ISP. All cables are Cat6.

As far as I understand, I can tell that this could be the reason why my internet speed is being limited to 100 Mbps. But I just want clarification whether this is an issue with the router itself or an issue on my ISP side. If it's an issue with the router, please let me know what I can do to fix it. Otherwise, if I can eliminate the router as a possible cause, then I'll take up the issue with my ISP. Please let me know. Thanks.

    OK. 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.

    What actual modem is connected to it? 

    Have you checked the cable from modem--->router? A sketchy cat 5e can cause a lower connection.Try replacing it with a high quality cat 6 cable.

      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?
