Hello, the past few months I have been having issues with my Nighthawk xr300. Seemingly at random my wifi and ethernet connection speeds will drop from 350mbps to 70-100mbps. Last time I was able to resolve this issue by switching from the first ethernet port on the back of my router to the forth. I have tried searching the internet for answers and have tried a lot of the recommended solutions but none seem to work for my current situation. Any suggestions would be appreciated, thank you.
Things already tried:
- Rebooting router and ISP modem both through software and hard reset
- Updating firmware of Nighthawk xr300
- Factory reset of Nighthawk xr300
- Isolating router as issue (Direct connect to ISP modem gives normal speeds of 350mbps)
- Try all four ports on back of Nighthawk xr300
Firmware: 1.0.3.78_10.3.59
Note: Nighthawk XR300 wouldn't show up for associated products
Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update? Be sure to restart your network in this sequence: Turn off and unplug modem. Turn off router and computers. Plug in and turn on modem. Wait 2 minutes for it to connect. Turn on the router and wait 2 minutes for it to connect. Turn on computers and rest of network.
Has a factory reset and setup from scratch been performed since last FW update? A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch with a wired PC and web browser. Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200. https://kb.netgear.com/24089/How-do-I-specify-the-pool-of-IP-addresses-assigned-by-my-Nighthawk-rout...
Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
The XR300 is connected to my ISP modem Model: TM1602A. My computer is connected through ethernet to the XR300, and both my ethernet connection and wifi running off the XR300 seems to be throttled to 100mbps. If I directly connect my PC to the ISP modem there are no issues.

Thank you, seems like doing everything at once worked. My speeds are back to normal, the only issue is I seem to have developed another problem. When I access sites for the first time I get "This site can't be reached... DNS address could not be found. Diagnosing the problem... DNS_PROBE_POSSIBLE" Read online that this could be due to the router as well. The website loads fine if I reload the page, just wanted to know if this was an issue worth fixing or not. Thanks again.
