Speed. This is my problem. i have next combination - router Dlink 635, pci card DWA-547, USB adaptor DWA-140. Qos, wish off on router. Firmware of router 2.32. tested with windos 7 and xp.
tranfer speed in LAN - 10-20 mb, on wireless up tu 10 MB. Why so small?

. It is a solution to boost the speed transfer?. Before i turn off the Qos and wish the speed was 3-4 mb or so.
This speed is too small. what can i do to improve that speed. Thanks
