I can't get this TV to connect to a wifi network unless the network is unsecured. I can go through the steps of entering a wifi key for a secured network, but it always says "failed to connect", as if I had entered the wrong password (or as if there were some other problem with the network).
I had tried it on two different WiFi devices, a ZTE WiMax modem/router, and a Ruckus wireless access point, and in both cases it will connect when the network is unsecured but not when there is security and a key in place. While typing this I realized there was one more device I could try - my jailbroken iPhone can act as a WiFi hotspot, so I activated that (secured) and entered the key on the Sharp TV, and ... it connected successfully. So I really don't know what's going on.
I've tried various changes, like switching the security/encryption protocols. I haven't looked into upgrading the firmware on the TV.
Thanks for any advice you can provide (even if it's "this is the wrong place to post this ... put it in X forum/thread instead")
EDIT
Weird development one day later: Because I could connect the TV to my iPhone's WiFi, on a lark I tried changing the Wireless-N to WPA2-PSK security and used the exact same password I use on my iPhone's WiFi hotspot ... and it worked.
So now it seems like the Sharp TV is picky about what kind of password it uses??? The passwords that have not worked have been "3407774649" and "crospn156", and the password that has worked is "Beam5Kuge" (changed slightly out of completely irrational paranoia about publishing any password on the internet). So all-numerical, all-lower-case-and-numerical, and a mix of upper&lower plus one digit being the only successful one.
Unfortunately right now I don't have access to the Ruckus WiFi, so I can't change the first two passwords, but I've messed with a few different combinations on the ZTE router to convince myself that it is in fact the format of the password that makes the difference in the Sharp TV's ability to connect over WiFi.
Does that sound even remotely reasonable/plausible/etc? Is it likely that a firmware upgrade would fix it? Very weird.
Separate question (that I can research elsewhere): For streaming NetFlix over WiFi, will it matter whether I use Wireless-N or Wireless-G (with a clear 25' line of sight between TV and router)? Or is Wireless-G plenty fast enough to handle Netflix?
