Debian 8.2 Jessie - WiFi lento

Pessoal, há um tempo atrás eu postei aqui no fórum uma dúvida sobre lentidão no WiFi do Debian 8.2:

http://www.vivaolinux.com.br/topico/Debian-para-iniciantes/Debian-82-Wifi-caindo

Recentemente, isso começou a me incomodar mais ainda. Reparei que no Windows 10 que eu tenho no dual boot, nunca fica lento. Lá no Windows, esses são os detalhes do dispositivo:

Manufacturer: Intel Corporation
Description: Intel(R) Centrino(R) Wireless-N 1000
Driver version: 15.4.1.1
Physical address: 74-E5-0B-07-94-40

O interessante, é que tudo indica que estou com esse mesmo driver no Debian. No post inicial que eu fiz, me responderam que provavelmente era realcionado ao chipset da placa. Não consegui encontrar essa informação, e mesmo que encontrasse, eu não saberia como identificar o chipset correto...

Tentei os passos daqui, mas também não tive êxito...

Alguém tem alguma dica?

Obrigado...!

Encontrei a forma de fazer o update do chipset da placa wifi, mas já estava atualizado.

http://www.cyberciti.biz/faq/linux-find-wireless-driver-chipset/

Fiz um teste de velocidades através desse site

http://www.minhaconexao.com.br/

Nele, testando com o cabo de rede conectado, a velocidade de download está compatível com o plano que tenho, deu 12Mb e upload de 1Mb. Fiz o teste sem o cabo de rede, no WiFi, e deu praticamente a mesma coisa.

É isso que acho estranho... tenho certeza que daqui a pouco volta a ficar lento do nada...

Alguém tem alguma sugestão?
