Guideposts To Keep In Mind

● “Can't never could”● You CAN master all this WLAN stuff. Keep focused.

Day by day. Week by week. Month by Month.

● “Never give up”● So what if you miss a question? Big deal. You'll get

it sooner or later, because you NEVER GIVE UP!

● “All things are difficult before they are easy”● ISM, UNII, WAP, etc., etc. etc. --- all this stuff is hard

at first. But easy later.
