Xa ukwenza utshintsho manual isihlangu kwesinye iikhompyutha kwi-network, kusenokwenzeka kweli xesha lifutshane kangangoko ukudlulisela izicwangciso esele zenziwe ezinye iiyunithi womnatha. Ngaphezu koko, nongqamaniso yokusebenza kuqinisekiswa kwanokuba unodibaniso wireless. Ukubeka i parameters efunekayo yokusebenza yodonga lomlilo lo kuthatha ixesha elithile, kodwa ukuba ubaphathe ngokugculelayo, izithintelo zokhuseleko zinokuyithintela ezinye eyimfuneko inkonzo.

iimpawu ezongezelelweyo of network amacebo
