@PowerlineFW Hi, I'm a newcomer to TP-Link Powerline adapters. Where can I download the required PIB file to enable me to install FW-QCA7420-1.5.0.0026-02-CS-20200114.nvm? Thanks in advance.

@PowerlineFW Never mind, I read the PIB from my TP-Link Powerline adapters using open-plc-tools in (https://github.com/qca/open-plc-utils) Linux:
$ sudo plctool -i eno1 -p TL-PA4010P.pib <MAC address printed on the adapter>
$ sudo plctool -i eno1 -p TL-PA4010_TV.pib <MAC address printed on the adapter>
$ sudo plctool -i eno1 -p TL-PA4010_HOME-HUB.pib <MAC address printed on the adapter>
$ sudo plctool -i eno1 -p TL-PA4020P.pib <MAC address printed on the adapter>
I downloaded FW-QCA7420-1.5.0.0026-02-CS-20200114.nvm from the URL you gave, and installed it with the applicable PIB file using the tpPLC utility for Windows running in a Windows 10 VM (virtual machine) in my Linux installation. I could have used the plctool command in Linux instead to update the firmware, but it was easier for me just to use the TP-Link utility in a Windows VM.
Anyway, no more drop-outs. What a difference. Thanks.
Just to reiterate, the firmware you posted does work with the following TP-Link Powerline AV600 adapters I have, as they all use the QCA7420 chipset:
TL-PA4010
TL-PA4010P
TL-PA4020P

@PowerlineFW I've been trying to fix my TL-PA4010(UK) V3 but so far have had no luck flashing the new firmware. I tried through the TP-Link app after downloading my PIB files, but that bricked my adapters. I have tried flashing through plcboot/plctool but can't get the adapters to write the firmware (due to no softloader being present). The TP-Link app fails the firmware update immediately. Do I need a separate softloader file to get the firmware to flash onto my adapters? If so, where can I find that?

@typhoon_2099 I flashed my TL-PA4010 V1 by this firmware and I have no problem.

@2MEX2 What exact commands did you use? Whenever I try to flash I get an error (no NVM softloader present in flash memory, 0x71). I can run the new firmware without flashing but the device is bricked, so doesn't do anything without using plcboot.

@2MEX2 Oh. When I used the TP-Link utility it updated for a while then failed, which also bricked my V3 adapters. My V1.2 adapters updated fine, and all 4 were upgraded using their PIBs downloaded from the devices.

@PowerlineFW Where can I find a softloader? I can't get my adapters to save the NVM/PIB to flash without it.
