In one room, I now wanted to additionally have WIFI.
This did not succeed, because the existing TP-Link Network does not recognize the (own) additional wireless adapter. The English description was kept simple and saw such a situation not before.
Even network Lore could not help me.
Too bad ...
The reversal / repayment was accustomed professionally.
Overall, I can not give only 1 star pale because I am of the opinion that such a configuration is nothing special and should also be possible.
