Just because battieries aren't old doesn't mean they're any good. Replace the hub batteries with a fresh set. For me, unusual behaviour creeping in is usually a sign of batteries going. A fresh set does the trick normally.rayhuang said:I replaced the computer battery and the batteries in the hub arent very old. Is this a hub battery issue?
Otherwise, talk to Saris, if you've done all the diagnostics you can, then you may just be unlucky and have an older hub with some problems. They will fix it/replace and return quickly - they have been excellent in that regard, even to me here in Australia.
