I am living in the Netherlands where we have cable TV (Ziggo). Because to many Ziggo clients in my neighborehood I changed my Ziggo box from 2.4 GHz to 5GHz. My downloadspeed increased from 15 mbsec to 200 mbsec.

But I tried to connect the TP link router with the 5GHz configuration, but that is not possible. I can connect it to tyhe 2.4 GHz configuration. Can some helps me?

Oh, you are allowed to answer me in Dutch ;)
