Netgear nighthawk r7000p Internet speed low compared to a different router on the same line

Thanks for taking time to respond to me.

I finally was able to fix the issue, i did had to logout from my ISP account and update the router to latest firmware again and reset to factory settings and log back to ISP account for it to work. Not exactly sure though was the log out and login of ISP worked or update and reset of router worked or combo of it worked, but its back to the ISP speed of 150Mbps now (it was running at 20 Mbps during the issue).
