Estou tendo problemas para conectar um telefone celular NOkia à minha rede wifi doméstica.
A rede wifi é fornecida por uma placa sem fio em uma máquina executando o Debian Testing e o kernel 2.6.26-2-686. Os carros são D-Link O DWL-G520 está funcionando no modo ap e possui criptografia WPA ativada.
A rede sem fio é fornecida pelo hostapd usando o driver madwifi. As máquinas Windows e Mac funcionam corretamente com essa rede Wi-Fi.
Quando tento conectar o telefone Nokia à rede Wi-Fi, recebo essas linhas no meu dnsmasq log (para ver linhas sem quebra automática, aqui está o link pastebin por conveniência - link ):

Alguém sabe que o problema pode ser?
Se eu desativar o log de consultas do dnsmasq dhcp, ou seja, se eu diminuir a verbosidade do log, tudo que vejo são duas linhas de DHCPDISCOVER (ath0) e DHCPOFFER (ath0) repetidamente no log sem aceitação pela célula telefone.
Parece que o telefone não está aceitando a oferta do dhcp.
No entanto, se eu der ao telefone um endereço IP estático em sua configuração, funciona corretamente na rede wifi. Então parece que o problema é relacionado ao dhcp.
Dicas? Sugestões?
Material instalado:
$> dpkg -l dnsmasq hostap* | grep ^i
ii dnsmasq 2.50-1 A small caching DNS proxy and DHCP/TFTP server
ii dnsmasq-base 2.50-1 A small caching DNS proxy and DHCP/TFTP server
ii hostapd 1:0.6.9-3 user space IEEE 802.11 AP and IEEE 802.1X/WPA/
Obrigado. PS: Aqui está o dump tcp do DHCP para mais informações (com os endereços mac alterados):

Seu telefone está solicitando a opção 120 (sip-server), entre outros. Os outros valores estão sendo retornados, mas esse não é.
Até onde eu sei, essas solicitações são opcionais, mas é possível que a Nokia não consiga lidar com a falta de valor para essa opção.
