On at least a couple of occasions the Tablet client has been unable to connect, returning an error message advising the Hava unit is unreachable and may be switched off.

The Titanium is connected via CAT5 to my Wireless ADSL Router (SpeedTouch 585). All other devices connect via Wi-Fi.

The first time this occurred I power cycled the Hava and all was good. Second time round I thought I would first check things from the PC which actually connected fine. I tried again from my N810 but received the same error so then performed a remote reboot of the Hava unit via the PC Player but this didn't change things. i.e. Hava unit came back online and PC Player reconnected fine, but N810 still couldn't see it.

At this point I knew all devices had working network connections, e.g. PC <--> Hava, N810 <--> PC. So this time, rather than power cycling the Hava I reconnected it to another Ethernet port and it worked!

Not sure what the issue was, but in the event this happens again I'll try to gather more information before attempting any fixes.
