Thanks for your suggestion Paul. Yes the Antivirus the same, Firewall same and used same internet connection for testing...
Turns out that the laptop is also now experiencing the same problems but is able to handle about twice the amount of upload data ... we really aren't talking about large upload files here... I would love it if I could upload more at least 5MB at a time but no so. (Most people complaining of the same issue are trying to upload files over 10M😎
So.,.. laptop will handle upto around 3mb of file transfer and desktop absolutely refuses any file size over 1mb.
Soooooo where shall I go now... thank you again.
