nevjerovatno šta je na kraju bilo ...

• prvo sam uzeo svoj notebook i isključio sc_linksys_1 pa se zakačio wirelesom na router stan_sa - 192.168.45.2

i to bez problema - ping time cca 4-5 ms, a signal 35-40%

onda sam upalio sc_linksys_1 i tu sam dobio ping 12-13000 ms ?!

na kraju sam otišao do LAN router-a koji je poludio od treptanja

isključivanjem kablova jedan po jedan došli smo do utičnice 2, koja je vodila do gb router-a u mojoj kancelariji

pa sam zamjenio ovaj router, pa mjenjao kablove ... ali je opet dolazilo do problema

na kraju je lociran mraka-1 kao problem, zamjenio sam njegov kabl ali i dalje problem

i kada sam njega ugasio mreža radi a ping notebook -> sc_linksys_1 preko wireless-a je cca 1-2 ms

e budaleštine ...

ovo samo kazuje da je nenormalno usporenje hanoramaglas izazvano nekom radnom stanicom ili switchem koji guši saobraćaj radi generisanja kolizije
