When you say mesh do you mean you want it to act as a wireless bridge / repeater, because as far as I know,1142s do not have this capability.Also, do you have any output from the console -- "show log -- to see what the 1142 is doing when it resets?he is what sounds like is the key at this point.A current copy of your 1142's config -- minus passwords and other sensitive info -- would be helpful
