• txuas rau cable ncaj qha mus rau ib tug computer tsis muaj yuav mus los ntawm ib tug router (router);
• xyuas cov kev ceev;
• kho cov ntaus ntawv configuration rov qab mus rau lub Hoobkas neej ntawd hais nqis;
• Yog hais tias tsim nyog, hloov cov firmware ntawm lub ntaus ntawv, saib xyuas txaus txias.
