model=RT-AC56U na model=RT-AC68U

odmpid=RT-AC56U na odmpid=RT-AC68U

ATEMODE=0 - upewnic sie czy to jest 0 - jak nie to zmienc na 0

zmiana clkfreq=800,666 na clkfreq=800,533 - zalecam to gdyz jak trafily sie was slabe RAMu to router moze nie wstac

w 3 miejscach MAC adress tutaj troche zamieszania bo AC68U ma ina kolejnosc

et0macaddr= XXX(AC56U) wpisujemy w miejsce et0macaddr=

3 na samym dolu w waszym CFE AC56U 0:macaddr= XXX(AC56U) wpisujemy jako 2gi na liscie od gory CFE AC68U 0:macaddr

2 na liscie od gory AC56U 1:macaddr= XXX(AC56U) wpisujecie na 3 na liscie AC68U 1:macaddr=

jest na poczatku roznica 1:macaddr= albo 0:macaddr= - tego nie pomylcie gdyz wtecy pomieszaja sie MAC (0:mac to LAN i wi-fi 2.4Ghz, a 1:mac to wi-fi 5GHz_ - jak pomylicie nie wiem czy wstanie router albo czy radia beda dzialac. tak to rozpisalem zeby ktos przypadkowo po kolei nie wklejal MAC swoich

dodatkowo tak powinny wygladac te parametry 

model=RT-AC68U

ATEMODE=0 - Asus wypuscil czec routerkow z 1 (albo takie CFE mozecie znalesc w necie) - to ma byc 0, inaczej raportuja uzytkownicy nawet w AC68U rozlaczanie wi-fi

odmpid=RT-AC68U
