Have a look at https://community.tp-link.com/us/home/forum/topic/204234 Upgrade the firmware (PLC part), but do this incrementally for each adapter: TL-PA8010 and TL-WPA8630 V2. This improves the connection stability (less dropouts, maybe completely gone) and much higher transfer rates. This is not difficult and read the thread on how to update the firmware on both devices. Some posts are quite detailled on how to do this. Read the first few posts and after that start reading at the last post and work your way back.

OK thanks for the reply. That's a loong thread with some 79 messages and masses of part numbers & firmware references over 8 pages so some reading to do...

It's not especially clear how this system hangs together. I have a TL-PA8010(UK) and a TL-WPA8630(UK) both v2.0. The 8010 takes a NVM or PIB file and the 8630 takes a BIN file to upgrade.

From one of the messages in that thread "The WPA8630P is actually two devices in one. Its a PLC device with an AP attached to it, everything in the same package. As such, there are two parts that can be upgraded, the PLC part and the AP part." which makes sense, but my 8630 only accepts a BIN file (which I think is for the AP)?

Can you let me know which file types do what? I really don't want to brick my adapters

@BillyWhizzz Just read the thread again. WPA8630(P): the tpPLC app only shows the firmware version of the WIFI component. To check firmware version of the PLC component install FRITZ!Powerline v01.03.00.

TL-PA8010(UK) V2: can be updates with the tpPLC app (nvm and pib)

TL-WPA8630(UK): can be updated with the old tp link app (nvm and pib) (post #26)

Extract your own pib from your devices (pib is device specific; however you can use a generic TL-WPA8630(UK) V2 and  TL-WPA8010(UK) V2 from the firmware package). Update incrementally, If your PLC firmware is 2.0.x update with 2.2.x first, 2.4,x next, ect.)

Still trying to work out, what exactly is a PIB file?

I uninstalled the tpPLC and reinstalled the "old" version from 2018 which displays nothing except for the screenshot below.

So, I need to install a competitor's utility to find out my version (2.2.2.0), replace the utility with some old software and load multiple versions of a 3rd party firmware just to get a stable working product?? Thanks TPLINK, I don't think I'll be buying any more of your products soon. Not that you care.

Just to be clear I'm not having a go at anyone from the community - in fact quite the opposite you guys should be applauded for your work - but jeez this is frustrating!!

Never mind, I found the answer to this one... I need to reset the date of my PC before 12 Jan to make it work!
