I just upgraded my wireless router from a humble 802.11g 54Mbps Belkin to a shiny new Netgear WNR2000.
After a little issue with the connection speed on my laptop being stuck at 54Mbps, i'm now sailing at very nice 130Mbps.
The issue related to the security settings and my Intel Wireless Wifi Link 4965AGN card. This is from intel:
"Operating in 802.11n Mode
Intel recommends using security with your wireless network. The Intel(R) Wireless WiFi Link 4965AGN adapter can only achieve transfer rates greater than 54 Mbps on 802.11n connections when using AES security, or no security. You should only use no security when setting up or troubleshooting the network."
So how do you get faster than 54 Mbps? either don't use security OR make sure you are using AES Security mode.
