You have set up WiFi on a TV, right?
Up, up, up, Enter; left, left, left, left, left, left, Enter; down, down down down, Enter.... 15 minutes later - Incorrect password.
I don't think my Synology has built in WiFi either.
Yes, i have. It's a one time thing, and change once a year or so. Meh.
Synology can sit beside the Telus hub with a short cable. Easy enough.
Mind you I do have some Cat6 i ran in my place, but mainly to setup the main AP where I really want it. 12 devices or so, 4 are on Ethernet, only 1 really needs to be (Ethernet is a little more stable, but not noticably so, and you typically won't saturate the bandwidth for wifi anymore so speed is not a real issue).
