This problem is generalized. I have the latest U5 and X5-128 : same issue (even with the latest firmware update). Impossible to keep Wi-FI connected more than two days (some time connected but w/o internet). I tried all network settings, no change, in two different big cities. Reboot my Bell 3000 router, not change at both locations. I have other streaming boxes (Formuler GTV, Skystream, Sony TV with no such issue).
I am very disappointed because the box is the fastest on the market (I have three X5 and two U5 special edition). But unforunatelly, my family is not expert enough to handle this issue when I am out. So I am the only one using BuzzTV now.
Do you have any plan to fix this issue?
