My apologies, you've mentioned that already and I neglected to read It.

In terms of a wireless card, @roger_smith has made some great recommendations. With regards to what system (PC), as mentioned, you don't need anything with superior specs. You've posted your budget (1000$ at the max), so just look for one that offers best value for money.

If you need assistance with what's considered as good value for money, just let us know.

Would it be possible to help me right away and just find one as I am not confident that I am good enough to evaluate what's good and bad
