Error after R7960P Firmware Upgraded to 1.4.2.84_1.3.42

While I'm grateful for you drawing engineering attention to this issue/thread, for 4 CONTINUOUS MONTHS your customers have been on these forums - for lack of any other place to report - that you have broken DNS on MULTIPLE Netgear router models (mine is an R8000, numerous threads for that one too).  We get errors like the one below endlessly.  I have just ordered a replacement router (obvious not Netgear, and never again) because I'm left with a choice of rolling back several releases and reverting a number of critical bug fixes or having constant errors like:

DNS error, fittingly on Netgear Community site

My short story....Please pass this on to Tech support even tho it concerns R8000P AC4000....Thanks !

*Purchased R8000P AC4000 Dec 2020 Firmware 1.4.1.50

--Router worked satisfactorily  and chose to attempt to update firmware in Feb.....unsuccesful as manyyyyy are aware !

--revisited updating months later since router was still working satisfactorily and VIA these support forums discovered the problem with

Firmware 1.4.1.50

--On 11/29/21 after re-reading many new threads concerning the flaw, chose to re-try the 4 steps I ran across earlier in year

1* updating thru router menu

2* manual download of newer firmware chk file

3 *attempted thru Netgear app

4 *by following How to upload firmware to a NETGEAR router using TFTP client? | Answer | NETGEAR Support

Gave in this past tues 11/30 and called Customer service...

* Dealt with first agent, very cordial/helpful....tranferred to next tech

* Informed 2nd tech(Ashish) of issue, also vey cordial/helpful...was informed I would be contacted in 24/48 hrs to further my case

* 12/2 rcvd email approving free replacement with refurbished unit....RMA # 3683766 Case ID 45391292. I personally chose $17 shipment whereby they send unit when available.

* 12/3 Rcvd unit

* 12/4 placed refurbished unit into service and for next few days dealt with DNS and page loading slowness issues. Checked issues on my end, changed DNS servers to google servers....8.8.8.8/8.8.4.4 with no sucess

* 12/6 ran across this thread and others threads concerning V1.4.2.84_1.3.42 DNS issues

* Today 12/7, reverted back to V1.4.1.68_1.3.28 and so far have had no DNS issues and page loading is back to as it should be.

Personal lesson learned....will not up date firmware until I check these support forums for satisfactory firmware update !

Thanks,
