Wireless connection drops after 10-20 seconds on Acer Aspire V3-572-56T3 running Windows 8.1

Boarster

I'm having major problems with connecting to the wireless network in the office. It sees the network, allows me to enter the security credentials, then connects (with confimed internet connectivity) but drops out after 10-20 seconds. I have tried the wireless network at a friend's house which worked ok without any interruptions, so it is definitely nothing wrong with the hardware. I'm using a brand new Acer Aspire V3-572-56T3 on Windows 8.1, with all the latest drivers/patches loaded and have tried fiddling with many of the advanced settings for the network adapter to no avail. I logged on to the router to ensure all settings, encryption standards, channels etc. were matching but the problem keeps persisting. This has been ongoing for two days now and is driving me insane as I really need to have wi-fi working in the office. Plugging an ethernet cable straight into the router works fine but it's not the ideal solution (and is posing an OH&S hazard as it is laying on the floor). Can somebody pleeeease help!!?

 

FYI I have run diagnostics several times & the one thing that stood out was this:

If your laptop wireless worked good at another location it's probably not the Laptop wireless that is the problem. Try shutting down the laptop, rebooting the office router and then start the laptop.
