... aneb jak Vas Node vidi nase AP ...

Z tzv. MAC adresy (tj. MAC vaseho Ovise nebo Asuse atp. nalepena typicky na stitku zarizeni) vidite z bezp. duvodu jen posledni 2 bajty, dle nich muzete snadno detekovat sve zarizeni. Pozor, MAC adresa neni vetsinou shodna s adresou vaseho sitoveho LAN adapteru, kterou vam na WinNT/2000/XP vypise prikazem: ipconfig /all

Hodnota rssi (Receive Signal Strength Indication tj. cesky intenzita signalu) by mela byt od -80dB (horsi) do -50dB (lepsi), pokud je jeste nizsi jak -80dB (pozor, zaporne cislo), muzete se setkat s vypadky signalu (casty vyskyt spatnych packetu), naopak vyrazne lepsi hodnota muze zrusit ostati klienty s horsim signalem! V takovem pripade si musite nastavit na vasem zarizeni nizsi vysilaci vykon (zbytecne velky vykon muze zpusobit take znacne zaruseni (Noise) samotne vasi anteny).
