Internet+napake

Sam sem malo gledal nastavitve modema in sem videl da imam še kar veliko število CRC in HEC napak. Sem prebrskal in vem kaj pomenijo, nikjer pa nisem videl da bi pisalo, koliko napak je sprejemljivo. Pa še to, ali je še kaj takega, kar ne spada pod "normalno"?

Potem dobro. Samo zanimalo me je, ker se je veliko napak pojavilo v 4 urah.

Zdaj pa je napak veliko več, je pa tudi res, da je 8 ur. Je to res normalno?
