Hi Dave
Firstly, if you're not sure what you're doing do not change BIOS settings. You can do more harm than good.
If you are using a wireless connection and you say it's dropping out "a few" times a day then I don't think you have a problem. Rather than paying for something you don't need check that your drivers are up to date . .

and also check to see if your laptop has a battery saving setting. Here is mine
make sure your laptop doesn't turn it off itself. It makes little sense paying for an external wireless card unless you have range issues.
Any questions feel free to ask.
Cheers!
Rich
