So, my brand new dual-band Airport Extreme has been working great for the last 2 weeks since I bought it. Today I connected an external hard drive (WD Passport 500Gb) via a USB hub, and it was working great for a few Gb of file transfers. About an hour later, I transferred another file, and the Airport ceased to work halfway through; I went to check and the Airport was completely dead. No lights, hard reset does nothing. Any ideas as to whether it's co-incidental that the Airport broke just hours after I connected an external HDD, at the time data was being transferred?
