You did well to make that move. Well done. A lot of people don't.

Changing ISP is just one event that needs a reset of the router. Your experience suggests that running the wizard achieves the same thing as a reset.

The old service, or an old modem, will create various settings on your router. Change the stuff in front of it, and you need to wipe out those settings and create new ones for the new network.

Glad to hear it worked for you!

Thank you for the suggestion.  I had not enabled before, but when I went back to enable and read the process of doing so in the manual, it occured to me that I never reran the setup wizard after changing data suppliers earlier in the year.  I reran the wizard and at least for the time being the problem seems to be resolved.  After testing I also enabled IPv6 in the auto config mode.  Thanks again

Did you try enabling IPv6?

I have the same problem, upgraded to latest firmware yesterday constantly need to refresh page to eliminate "page cannot be found error."   Using VPN resolves the issue.  Considering going back to previous firmware version, but not sure how to find. 

Thanks for your reactions. At least we know we're not alone with this problem. Also personally I'm now sure this has nothing to do with my setup (double NAT), which works without flaws with the older firmware.

However, reverting firmware is not an ideal solution in the end. From hrabcakm I understand that for the R6400 FW 1.0.1.74 (the latest firmware at the time of writing this) still gives problems. So that is at least half a year of Netgear not doing anything about faulty firmware.

I know this is a user community, but I feel it's a disgrace that Netgear cripples their devices by their sloppy firmware updates. Considering the kind of feedback I had to give Netgear in the past (even when my device was still under warranty), I'm not all impressed by the competence of the developers at Netgear and certainly underwhelmed by customer service. I don't think I will buy another device from them anytime soon, even though the hardware is better than that of some of their competitors.

(For those who are interested in what I mean by sloppy coding -apart from rendering the device useless with the past few pieces of firmware - here is an example with regard to port forwarding, where port numbers had to be unique:

Hi,

Same Here. I have following two routers with exactly same issue, 2 differents ISPs.

R6400 FW 1.0.1.74 - Long term issue, present also in previous versions of Firmware

R8000 FW 1.0.4.76 - Same issue, occurs in last 2 Firmware versions.

Hope fix will come soon.

Regards,

M.

It turns out this is a known issue that is affecting many models. For my router R8000-V1.0.4.68_10.1.75 dated 01/08/2021 is the last known firmware that doesn't have this issue.  Downgrading fixed it for me.

I have R8000.  I recently upgraded firmware that was several years old and have this same issue. I'll reset to factory and try reverting firmware back a few revisions at a time and see if it fixes and which revision started this behavior.
