Model : TL-PA9025P KIT and TL-WPA4220

Hardware Version : V1 for TL-PA9025P KIT and V1.3 for TL-WPA4220

Firmware Version : Last ones



Hi,


I bought four TL-PA9025P that works correctly all together at around 1 Mbps (whatever place, never succeed to get more, surely because of the distance between CPL devices).
Thanks to the promo available in France I receive a TL-WPA4220.
Pairing between all the TL-PA9025P and TL-WPA4220 is going OK, wifi is working but after few minutes the CPL indicator led of the three TL-PA9025P is getting red and transmission start becoming very bad.
So bad, that I cannot stream or transfer any content correctly anymore.

If I disconnect TL-WPA4220, everything is coming back fine.

Is there a compatibility issue ?
If so why TP-Link have you made a promotion that encourage purchasing TL-PA9025P, knowing people will not be able to use these device with the TL-WPA4220 ?

Thanks for your reply.

Regards
