I have a belkin network USB hub, model F5L009, this is in turn connected to an SMC barricade N SMCWBR14S-N2 wireless router. If I try and connect under N it recognises my hard drive but gives me an error when connecting. I have entered firewall and other settings correctly, and am able to connect to the HDD fine when the router is set to use g or n instead of just n. It seems my aluminium MacBook is using g, is there a way to find out? Also any suggestions as to why I am getting an error? Neither belkin or smc documentation or websites offer a solution, and it seems strange for g to connect fine but not n.
