phone issues

OKay I've got an issue with my xperia play phone.
I don't know if aMuir here has a rooted xperia play phone or not. But wait it gets more complicated.. okay I rooted my xperia play cause I needed it to be a Wi-Fi hotspot and the best Wi-Fi program I know of for android is barnical Wi-Fi teacher..


The problem is it's just not spitting out Wi-Fi like it should. I can pull up my host name on my pc n such but it never connects.
I've tried everything. And I don't know what the problem is.. I think my phone is only spitting out an 802.11 n signal. Could that be the problem? Can I make it spit out g or b?

Does anybody know of a better program then barnical ?
Or even what's up???
