I'm having a problem with the internet connection in my HP Omni 220( this has better specs and is brand new). It is slow unlike when I use the net in my Lenovo laptop. I tested both in speedtest (same location, same server) and my laptop's internet speed is dramatically bigger. My Lenovo laptop's wireless adapter is Atheros AR9285 while my HP desktop is Broadcom 802.11n. What should I do? Should I buy another wireless adapter? If I will, what can you recommend? Thanks.
