I'm using the lastest version of the i62HD firmware and noticed there is a problem with connecting to WiFi networks that don't broadcast the network SSID. There use to be a similar problem with the M92, which was fixed in the last release (Onyx Europe) of their firmware. For some reason this fix was not replicated to the Onyx i62HD firmware build.
Please advise if anyone else is able to replicate this problem.
