So there's an optimum wifi hotspot near me and my phone connects just fine, as does my macbook, but when I try to connect on my pc it just kind of connects but won't have any internet access. I'm using a wifi adapter that's only for 2.4ghz 802.11n, could it be that the hotspot is 5ghz or maybe a/b/g? I've tried to google details about the hotspots but I can't find any information. Any ideas? Thanks.
