Help me configure my WiFi network correctly please? Speed issues.

Hey guys,

Let me explain the situation first.

I have a Desktop PC and a netbook. They are in the same room and so is my router. My router is a 2Wire from AT&T. All these devices support wireless G.

My file transfer speeds from my desktop to laptop is going at a dismal rate of around 800KB/s. I am connected to my router at 54Mbps with my WiFi cards on both the systems. I am trying to figure out where this bottleneck is and try and speed this up.

-I am in an apartment building. There is least interference on channel 11 so I have set my router to use channel 11.

-The router is set to work at either B or G but I know I'm definitely connected by G on both the computers since I'm connected at 54Mbps.

-I have full WiFi signal on both computers and there is hardly any interference in my apartment that I am aware of. My internet bandwith is perfectly fine.

-Transfer rates between these two computers through a LAN connection is blazing fast. Its connected at 1Gbps and transfer rates are around 100MB/s

-If I connect the desktop and netbook in the Ad Hoc mode, I get a pretty steady 2MB/s

-In the registry, I have set the NetworkThrottlingIndex to FFFFFFFF hex (so throttling is essentially turned off) but that makes no difference.

Does anyone have any ideas that could help me?

Thanks!
