I keep having to replace , my & wife's 'tablets ' & ' laptops ' due solely to " WiFi " being g out dated .
They are still usable with a long " cord " to our modem .

PS. : who is going to make a transmitter box , plugged into the " Ethernet port " on the nbn , to adapt the old wireless ' receiver ", ( in our tablets ) to the new frequency, we could dispense with the " Wifi router " .
plug in the " new transmitter " .
And
be happy again .
