dokupoval som wifi aby som mohol hodit server do kumbalu. problem je ze sa dost casto z nicoho nic odpaja tak na 10-15 sekund kym sa znovu pripoji.
system je Ubuntu server 10.04. teraz bezim na jadre 2.6.35. originalne tam je 2.6.32. skusal som taktize 2.6.38.
zda sa mi ze s tym 2.6.35 sa to odpaja najmenej. s 2.6.38 som ale napriklad aj na 2 metre dosahoval prenos len 1MiB/s kym s 2.6.35 az 3MiB/s. taktiez sa odpaja hlavne ak sa prenasa vela dat napriklad cez NFS alebo vela spojeni cez torrent. ak je aktivna len SSH tak je to stabilnejsie. karta je TP-LINK TL-WN350GD
