R7000 DNS Hiccups

Hello,

 

I recently setup a R7000 for home use and have been encountering episodes where I believe the DNS service on the router just fails/freezes. My internet on all my devices stops working, I am unable to ping any sites such as google.com. I can still login to my router and my wireless connection remains established, but internet access just stops working until it eventually corrects itself ~2 minutes after the hiccup.

 

I have already verified I am on the latest firmware V1.0.7.2_1.1.93, and have switched to use Googles DNS servers but no luck, so I believe something on device itself is hiccuping. Any suggestions/ideas?

Model: R7000|Nighthawk AC1900 Dual Band WiFi Router

Re: R7000 DNS Hiccups

It hasn't occured since I posted, I wondered if it was overheating and doing a soft reset as it was carpet. It is now on a hard surface.

 

I didn't want ot factory reset as it was a brand new router with new firmware and I hadn't made any changes. It is also not possible for me to directly connect my PC to my modem, they live in different areas of the house.

Forgot to add I am on a Windows 10 64bit computer using Google Chrome. No proxy is setup. Below is the Windows log entry corresponding with when DNS stopped working.

Hi Trippster36,

 

Reset the router to factory default and manually reconfigure. If still the same, try connecting a computer to your modem to test if the connection is stable from ISP. If connection is unstable from the modem, contact ISP. If stable, try changing the MTU size of the router or try to revert to previous firmware.
