That's not even the half of it. The official driver that Dell has for this card through their site is horrible, it constantly drops the connection (there are many that complain of this aspect). The solution was a driver that Microsoft put out via windows update for the very same card, and ever since I switched, I've been quite happy.
However this problem arose when I tried listening to music, and throughout all my searching I wasn't able to find a solution anywhere; closest I got was power & bios settings. I was very glad that you were able to help me pinpoint the problem, but was distressed (a few min ago) being unable to disable the A band via the current driver.. so it seemed as if I was presented with two choices: go with the Dell driver and fix the jittering, or stay with the Microsoft driver and keep a stable connection.
Luckily for me, on a whim I right-clicked the card in device manager, and selected Update Driver Software (through windows update), and there was an updated driver that I installed just a few moments ago, which fixed the jittering instantly.
I'm very happy and thank you sir for your help C:

Indeed, I would never expect such a ridiculous flaw in a Dell laptop... I think you should contact their tech support.
Well, glad I helped pointing you in the right direction at least.
