Is this a specific limitation of Tapo C500 or it's the same of other Tapo cameras?

@Hank21 i tried several servers and also the built in Speedtest, the results are always asymmetric

I have two Tp-Link Pharos CPE210 at distance of 100m, LOS, no big noise on them, this is the status on the server antenna: This is the status on the client antenna: These are the speedtest executed...
