Il mio set up è abbastanza semplice. 1841 con modulo switch (hwic-4esw) e AP (hwic-ap-g-e)
tutto funziona bene. ma non sono soddisfatto delle performance, inoltre sull'interfaccia dot11radio vedo tantissimi errori in input e output. Ecco la mia config e lo stato dell'interfaccia.

So anche bene che wireless è half duplex e molti degli errori sono dovuti a questi altri AP su canali che si sovrappongono.. ma onestamente il mio piccolo AP netgear (sempre wirless b/g) sembra dare performance nettamente migliori..
idee?
