fedora 17 - wifi - dhcp request timeout

[Boris Brinza]

Ahoj, mam problem s pripojenim na domacu wifinu (nejaky obskurny dlink 
di-524).
Este uviediem, ze 2 dalsie notebooky s win7 + 2 telefony problem nemaju 
(aspon co sa tyka spojenia, ten router je inak tragicky)

Z logov vidiet, ze na wifi sa masina pripoji, ale potom zlyha pridelenie 
ip z dhcp a netusim preco. Ked 3-4 vypnem/zapnem wifi adapter, nakoniec 
sa fedora pripoji, ale obtazuje to.
Podla logov sa snazi o dusu. ale potom pride DHCPv4 request timed out a 
je po zabave.
