Latest update bug: R6400 Firmware DNS issue (V1.0.1.74_1.0.48)
This latest update broke DNS resolving, so it randomly cuts out and doesn't resolve anything. Random web pages will just error out. Connection to generic services won't work at all. More can be s...
It's apparent that since the DNS problem arose, subsequent and unrelated updates have made the router(s) even worse. In fact, I think Netgear is imploding as we speak.
“Way to go Disney! I have disabled automatic updates because the last update from Netgear slowed my router down so much. I had to downgrade to a much older version that did not include the armour guard application to get my full isp speed back. I am afraid that this new patch will come with the same application that I had to get rid of that slowed down my router. Maybe it is time for a new wifi 6 router from a different company.”
“the same issue with the 6400v2 downgraded the firmware which helped get more speed but ultimately bought a new router the Rax50 to keep up with the speeds much happier now.”

I do however have a solution to my issue; I bought a non-Netgear branded router. Are you looking for a router with stability, performance and industry standard updates that don't break the the product altogether? Look no further.

- Guaranteed DNS functionality

Buy anything but Netgear today. Special thanks to olympos1625 for logging in the forum every day and ignoring everyone while having the time to respond to new threads. I hope everyone else gets a working router sometime soon because this is verging on class action territory when the product isn't end of life. Oh, how the mighty fall.
I am experiencing the same issues discussed in this thread on multiple devices with my R6400 after installing the latest firmware (V1.0.1.74_1.0.48.) Please fix this firmware issue. This is wildly annoying.
I had the same issue. The problem is with Firmware version 1.0.1.74_1.0.0.48. This can be found all over Reddit and this community forum, but it looks like NetGear is not accepting responsibility. They're instead telling people it's a problem with their firewall or with thier internet server providers DNS resolution. I've been using this router for 5 years without any issues until this update.
There are also documented cases of running wireshark to track the dns errors. Many are detected on resolving DNS inside the network (like the router's own IP address), so the Firewall and ISP DNS resolution aren't even in play.
I didn't want to do a factory reset because I have way to many advanced configurations set up in my router to go through setting up again.
I ended up rolling back to a previous version and then ran these commands in an elevated command prompt and it looks like it might have fixed the problems.
ipconfig /release
ipconfig /flushdns
ipconfig /renew
Just make sure to downgrade to V1.0.1.68_1.0.43. The issue is completely resolved by that version. The broken version isn't even available for updating through the firmware anymore, so they know there's an issue with it. Hopefully the next update will fix it, but if it doesn't have V1.0.1.68_1.0.43 handy so you can downgrade again if necessary.
