R8500 with latest V1.0.2.54_1.0.56 intermittently loses DNS
I replaced my R7000 very recently with a R8500 and am very pleased with the faster 5G speeds. I'm running the latest R8500 firmware, V1.0.2.54_1.0.56, but notice that my DNS disappears intermittentl...
Mikey94025 How's the connection after reset? I'm unable to replicate the problem you're having. The router is working perfectly with the connection.
Perhaps, it's a faulty unit.
Unfortunately my DNS outage happened twice again tonight (it was ~7pm, +/- 15 min). I was able to spend some time diagnosing and narrowed it to only DNS functionality through the R8500 itself:
- I can ssh to external hosts if I use an IP address. I can also make web requests via IP address.
- If I change my Windows adapter DNS from the router IP (192.168.1.1) to Google DNS (8.8.8.8) then the DNS and web browsing works again on my laptop.
- The R8500 Basic and Advanced tabs both reported that the Internet status was GOOD.
- The first time it failed I changing the R8500 DNS from "Get Automatically from ISP" to a static IP (8.8.8.8 and 75.75.75.75 - The Comcast DNS) but it did not restore the DNS. I changed it again to (8.8.8.8 and 8.8.4.4) and DNS came back. I've seen the issue with static DNS before so I don't think it matters and restarting the router just often restores the DNS.
- I was turning off random functions and DNS went away after I turned off UPNP (and so the router had to restart).
This doesn't seem like a hardware issue since it's so specific to DNS. I can always return the router if I have to, but I'd first want to try hard reset or downgrade the firmware.

I did a reset of my router and then restored from a backup (I previously unboxed my new router with v1.0.0.something firmware, entered my settings, then did the firmware upgrade to V1.0.2.54 using the web tool and without a reset). I have not seen the DNS loss in the past few days, but it's not been that long yet and it would only be caught if I happen to notice it during my evening web use.
I tried installing the Netgear Genie on my Windows desktop PC (that I keep on all the time) to try and report if any DNS errors occur, but it doesn't seem to log if it happens and only shows a temporary taskbar error popup when it occurs. So I can't use it to tell me if DNS goes away intermittently. But I setup a script to ping a DNS name every 5 sec and log the results. I should now be able to see if DNS ever goes away during the next few days. If DNS stays working for 72 hours then we can assume that the reset cleared the issue.
Feel free to give us an update.
I'm happy to report that no DNS interruptions were discovered during my continuous monitoring for the past 72 hours, so it appears that the hard reset made the problem go away. I confirmed that my script would catch DNS interruptions when I explicitly disabled my network interface and also when I set the R8500 DNS static IPs to invalid addresses, so I'm confident of the results
The above was all with 1.0.2.54. I am also upgrading to the latest 1.0.2.64 firmware now and will also run the DNS-monitoring script over the next week just to make sure. After the upgrade, I again did a hard reset of my modem and then restored my settings from backup.
