network.download stalls in 4G/LTE networks?

Hi,

Has anyone encountered issues with asynchronous download function “network.download()”? My app is  downloading a zipped file about 7MB in size and the app just tends to stall midway through the download. But on a 3G the download process seems to be stable. 

Any help/comment in this issue will be greatly appreciated.

Regards,
