NAS Samba - problème débit montant en ethernet

Bonjour à tous,

J'ai un petit souci, ne concernant pas directement ubuntu mais son grand frère debian, connaissant la réctivité du forum ubuntu-fr.org, je me permets de vous en faire part.

D'un côté un NAS (Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.32-1 x86_64 GNU/Linux) avec un partage samba (samba 2:3.6.6-3).
[ Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06) ]

De l'autre un client dual-boot Windows 7 et Ubuntu Lucid (backtrack 5r3, avec un kernel 3.4)
[ Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20) ]

Et une passerelle Freebox v6.

Lorsque le post client est connecté en wifi, les débits montant et descendant sont aux alentours de 3-4 Mo/s.
Mais, lorsque le poste client est connecté en ethernet, le débit descendant est de ~60Mo/s et le débit montant de 25 Ko/s !!!

Je suis quelque peu désappointé d'être l'heureux possesseur d'un upload plus faible en LAN qu'en WAN !!!

Pourriez vous m'aider à résoudre ce problème ?

Je vous fais parvenir le résultat de quelques commandes. Et merci d'avance !
