Error using Windows Update while connected to a WIFI

Hi to All,

When i try to update my operating system using windows updated while connected to a wifi, it always give me an error below.

Error Encountered

There were some problems installing updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80240439)

when i try to connect my device on Lan it won't have this specific issue and it will update properly.

"My question is that why couldn't i update my OS thru windows update if connected to a WIFI, while if connected to a LAN connection i could. "

Thank you for your kind answers....

Wi-Fi can have drop-outs [lose connection] at various times, no way to know just when. It can happen with the adapter in the computer or the Router. It can happen from radio-type interference from known or unknown sources/devices. An example I experience with one of my Notebooks is from running the microwave oven but only lasts for about 10 seconds after the oven stops. I watch the Internet icon in the Notification Area to note when it happens.

May i ask, is there a way to fix this issue? for me to update my OS via Wifi?
