Brian, when you say that a "lag" is normal ... what sort of lag would you find acceptable?
I sorted out my network access to the area behind the tv, in the living room last Friday night (15/07/2011) ... this took a lot longer than expected (but that's not necessarily a concern here) so I didn't have time to really investigate the Portal ... but I did open it, browse the iPlayer and watch a minute or two of a programme (Torchwood) in SD and then the same programme in HD just to check that the bandwidth of the wi-fi bridge that I'd just installed was up to it all ... I don't remember any particular "lags" from that brief tiral. I then went away for the weekend.
Since arriving back, whenever I push the TV Portal button I get a "Connecting" message on the screen for 10 secs, then it carries on showing TV for around 1.5-2 mins, then the screen goes black (but with tv sound) with the "Connecting" message and rotating circle shown, for another 1.5-2 mins then (slowly, over another minute or so) the TV Portal screen gets built up. These delays make the thing completely unusable!!
I've tried turning off and back on, changing the network settings and re-setting to factory settings and nothing seems to get me back to where it was a few days ago ... I may consider re loading the firmware I got v1.02.20 over OTA last week, but is that likely to resolve this?
Thanks in advance.
