<br>
Sono stati flashati con OpenWRT e non si riusciva ad uscire su Internet.<br>
Pingando gli IP della WLAN non dava alcun problema.<br>
Pingando gli IP della LAN o ad es. <a href="http://ninux.org" target="_blank">ninux.org</a> o qualsiasi altro dominio perdeva tra il 50% ed il 75% dei pacchetti.<br>
<br>
Cambiando il canale wireless da 11 a 8 (dopo aver verificato su entrambi i nodi quelli meno impegnati da altre reti e su quest'ultimi quelli che avevano canali adiacenti meno impegnati) il problema sembrava risolto, tutto funzionava perfettamente.<br>
<br>
Adesso lo stesso problema si presenta anche sul canale 8, in certi momenti funziona in altri no.<br>
Si sono provati altri canali ma la situazione non cambia.<br>
<br>
La distanza tra i 2 nodi e' di 200 - 300 metri.<br>
