Thank you for your answer,
Unfortunately it is not the answer I wanted. A MAC filter is a basic feature in any mid-high quality router in the market. You offered me a service that has nothing to do about what I requested, and that I already have with another company.
So, if none of the models offered by Swisscom has a MAC filter for the WLAN, can I replace the routher, that Swisscom sent me, for another by choice?
Thank you.
