I recently set up my Naim gear after a 3 month hiatus due to a house move. When we eventually got connected to the internet I set up the router with a long password with * in. When it came to getting my 272 on the network I tried and tried but could not find it on the remote handset. In the end I just changed the router password. Once I’d done that I then of course realised that I would have to re-input it on every connected device in the house! Very annoying!
~ If you can just type it in another program or look for the character via Google (like I just did) and copy and paste it into the appropriate place ~ sorry just realised that you are using a remote?
