This year one of my own routers was being picky about what devices it would work with.
The big clue it was not my laptop was a note about issues with iPads. On a hunch I installed an older router firmware and the issue vanished.
The good news here is it's at work so your IT staffer should work on it.

Certainly your IT staffer would know both these issues. Let them at it.
In parting, it's a shame the details are not here. If you read
I have a new P500 Lenovo laptop. It works fine on all wifi networks except for my work network (that works totally fine on all other computers and laptops throughout the building). No matter where I work - right next to the router, five feet away, etc - the signal is dropped every few minutes. This doesn't happen to anyone else, any other laptops. or anywhere else. Does anyone have any suggestions on what I can do? It's getting to be quite a pain. Everything I've found has either been suggestions to bump up the router, which works fine, or to update drivers, which I have done.
