Hello all. First post, so be gentle.. ;-) I have just bought a MAG254 and assumed that a TL-WN823N (300Mb mini USB) wireless adapter would work. I know now that I should have read some of the links here, but, I didn't! My problem is configuring the wireless settings on the MAG254. As I understand, I need to configure the MAG254, then plug in the adapter... But I can't get to the wifi config screen - just a dialog telling me "Wifi Adapter not connected". Am I missing something obvious? Any help gratefully received! Thanks...
