I have a DVR4575 unit and wish to use a wireless USB adapter with it as it states here that this is possible.
I have purchased this from Amazon however when I navigate to the network menu I do not see a WiFi option.
I have upgraded to the lastest firmware on the DVR4575 but still I do not see a WiFi option under the network menu. Is it only a particular type of USB WiFi adapter that is supported please or does the unit I have not support this function?
