I have a bredbånd connection via TDC HomeDuo Box. The declared speed are 20 Mb/s download and 2 Mb/s upload. Everything works as expected when it is WIRED connection. When I perform speed test using wired connection it shows me 18 Mb/s download and 1.7 Mb/s upload as expected.
However, when I use WiFi connection via TDC Homebox the download speed drops down to 12-13 Mb/s and upload speed stay around 1.5-1.6 Mb/s, which is not acceptable.
I have my old NETGEAR router which I connected to the homebox as a simple switch to test the wireless connection. When I am connected to NETGEAR I am able to get the same download/upload rate as via wired connection (18 Mb/s and 1.7 Mb/s).
That mean there is a problem with TDC's Sagem box WiFi. I have tried different settings, including channels numbers and 802.11n mode. Nothing helps.
Does anybody know why the problem exist and how to overcome it?
TDC's Sagem model is: F@st 35XX
TDC's Sagem FW version is: Fast3DK04_5AK042
