legacy drivers and wireless test drivers QUESTIONS

When you start MT installation you can check option: wireless legacy and wireless test… what is better?

Does this legacy option supports SR5 and CM9 cards?

Can you connect system which use wireless legacy with system which use wireless test version?

Is there incompatibility between 2.9.27 MT version and SR5 card? I heard that 2.9.27 cannot recognise SR5 or maybe it is pesonal experience?

don’t ever use legacy unless you have a really big specific reason to do so

legacy driver cannot detect newer card afaik
