Comprei esta placa PCI: Intel Centrino WiMAX 6250 .
Problema:
A placa wifi é detectada pelo sistema, carrega o módulo, etc, mas não cria a interface.

02:00.0 Network controller: Intel Corporation Centrino Advanced-N + WiMAX 6250 [Kilmer Peak] (rev 5e)
Originalmente, o cartão 6250 carregou o módulo RTL818X_PCI , eu o segui substituindo-o pelo módulo iwldvm que obtive para o wlwifi-6050-ucode , isso pode aparentemente ser usado para a placa 6250.
Com relação à questão do hardware na lista negra, falei com um técnico do fornecedor (Mecer) e parafraseando o que ele disse - se eu conseguir encaixar, deve funcionar - referindo-se ao cartão pci wifi
Aqui você pode ver a placa wifi instalada:

Eu vi este post , não é relevante, pois não consigo nem digitalizar
Além disso, observe. Eu tenho um switch de hardware, usando Fn + F11 , que liga e desliga meu wifi. Quando o wifi do laptop está ligado, um led deve estar em verde sólido, mas com este cartão wifi, nenhuma luz aparece para o wifi.
Isso implica algum tipo de hardware / incompatibilidade na lista negra?
Obrigado
