Slow download speed, fast upload speed? Mixing a TL-WPA7510 Kit with a TL-WPA8630P powerline adapter
Hi
My system of powerline adapters is composed of a TL-WPA7510 Kit, to which I have added a TL-WPA8630P. I have a fiber optic connection that can reach up to 280 Mbps in ideal conditions.
My problem is that, while the TL-WPA8630P works really well both in download and upload, reaching up to 100 Mbps in both directions regardless of where I plug it in the house, the TL-WPA7510 wifi adapter seems to struggle, only getting download speeds of around 3-4 Mbps and upload speeds of 40-50 Mbps - regardless of where I plug it in the house.
What is even more puzzling is that the TL-WPA7510 wifi adapter will sometimes work fine for 10-15 minutes when I unplug it and plug it somewhere else in the house, reaching download speeds of 60-70 Mbps and equivalent upload speeds, but then will revert back to its usual slow rates after that.
Using the TP-Link utility, I can see that the rates between the three adapters are completely fine, between 250 Mbps and 350 Mbps.
The fact that the TL-WPA8630P seems to work really well everywhere in the house seems to suggest that this is not a problem of wiring, but maybe of compatibility between these two powerline adapters?
Thank you in advance
