Hi. I have a small problem. First of all, my Wi-fi card is an Intel Centrino 130N. When I connect to the Internet directly, the speeds I get are: DL: 11 MB\s and UL: 9 MB\s. (I know the difference between MB and Mbits). Although, when I'm connected through wireless, I get: DL: 3.4 MB\s and UL: 4.7 MB\s.
First question: how do I get my DL speed to be higher than the UL speed in wireless mode ? I read somewhere I have to disable QoS and WMM, but I simply can't find that option in the router's settings. Any ideas ?
Second question: even if I am in the same room as my router, when I check the status of the wireless connection, the maximum speed is 72 mbps. Should that be 130 mbps, as I run it in N mode, not G? Any ideas on how to improve that ?
I have Win 7 and all the latest drivers and everything.
Thanks in advance :).
