@PowerlineFW  the tplink support web site lists two routers a tl-7010 and a tl-7010(p). For the first one there is no firmware upgrade but for the second with the p suffix there is an upgrade. With that information I chose not to upgrade the home plug as I would not wish to risk putting the wrong firmware in and making the plug completely useless.  As far as the original problem is concerned I have somehow, I changed a lot of settings on various devices back to factory settings and reset the whole network including making the printer able to act as an access point ( which is unused ) . Once completed it works which was the object of the exercise. 
 

thank you for your answer it gave insight. 
 

@PowerlineFW 

I have a TL-WPA7510 KIT that is running slow so I am trying to update the firmware. I have updated the TL-WPA7510 extender using the tpPLC utility with the latest firmware from the TP-LINK download center (3.2.4_75102_181126_901). The tpPLC utility used a bin file format for the extender. I would also like to update the TL-PA7010 adapter but the tpPLC utility requires a GGL file for the adapter update. No GGL file is available from the TP-Link download center. I have downloaded the GGL file from this post but the update fails when using the tpPLC utility to install the firmware. The current firmware version of the TL-PA7010 adapter is (3.2.4_7010003_180102_901).

Any help with this issue would be greatly appreciated.

@zip031 Did you try the D-Link PLC utility? For the TL-WPA7510 with the bin file the WLAN part was updated, the powerline part not.

@PowerlineFW - I just purchased two of the TL-PA7017 kits and would like to upgrade the firmware if it available. Where could I download the latest version? I have looked at the support site for the kits but the latest firware showing is not fro 2021.

@PowerlineFW - I did, it failed on the two that I tried. Not a big deal, I can wait for the official release for these adapters.

Thanks everyone for the information you shared! It really helped me out!

I know this is an old post. But can anyone confirm if the version I see available for TL-PA7027: "TL-PA7027P KIT(EU)_V1.0_200113" with the file "BCM60350_v1.0.0d_20200113_EU_PA7027Pv1.0.ggl" also works for TL-PA7010 and TL-PA7017 models?

The chip model (BCM60350) is the same for all models as well, as far as I can see in each specific firmware file. The versions for each equipment, however, are different: PA7010 is V2 and PA7017 is V4.

Thanks

Thank you PowerlineFW - it worked for me not just on TP-Link HW but also for Tenda. I've just tried this on a Tenda PH3 AV1000 which was made in 2017. It also works for this.

BCM960355 based PCBs are all probably just rebrands/repackaged Broadcom reference designs. If you open the ".ggl" file in 7-zip and look at the contents of hw_version.txt, as long as hw_version, fw_version and fw_features matches with the latest firmware for your current product's support page - it will flash and it will work (these parameters matched what was on the Tenda PH3, and I've also checked in 7-zip, the 7017V4). What does change however, are the CFGs/paramconfigs.

It breathed new life into my Tenda PH3 by boosting the link rate of the PHY by 50Mbps. Previously it would be around 250Mbps. Now it is consistently above 300-350Mbps - with bursty behavior by peaking up to 400Mbps.

I used the firmware linked in the original post for the PH3:

"BCM60350_v1.0.0d_20200113_EU_PA7027Pv1.0.ggl"

EDIT: I flashed the TP-Link FW with Tenda's PLC utility.
