Well apparently there is some mention you have to use wireless to first access the ds exploit when first running the card on a >4.5 system. There is no mention of this anywhere in any documents not that there are any. it may be self explanatory, there should however still be documents of some kind.
Since the tech team is so busy finishing the New 3DS team they have not themselves produced any guides.
But I am working with the GW team, and some of authors of these guides linked above to soon produce a professional guide to be included in the final release which is due currently by next week or so.
Alot of times with BETA releases there is not much info, as things are changing and being improved, and their might be little bug 'workarounds' needed so it is best to read those two threads fully first before attempting to do things if you not sure about anything.
Take Care, and if you have any questions, its better to ask before trying something you might not uinderstand.
