I know this has been discussed before but I have not found any solution that works. I am trying to update 4.3.3 to 4.3.5. It should be about a 43 min download on my, admittedly, slow bband connection in rural France. I once got within 8 secs of finishing the dload before it timed out,aaargh! So this is not an issue about failure to install but one where the download fails entirely after usually about 20 mins and of course you have to start again from scratch. I have no other probs with connectivity with downloads with this or any other devices. Yes I have disabled a/v, firewall etc. Grateful for any help!
