D-Link DIR-655, Intel WiFi Link 4965a/g/n, Vista and 802.11n

[Guest]

Our home network consists of the subject line , a Windows Pro XP laptop,
Windows XP home desktop (both of these are wired to the router); no problems
there. Then I have the new gaming laptop (VISTA Home Premium) with the Intel
WiFi Link 4965a/g/n. This is the wireless setup: WPA2-P, AES, 802.11 Mode is
Mixed n,g &b, Enable Auto Channel Scan, Transm rate Best (automatic), Channel
Width Auto 20/40 MHz, Group Key 3600 seconds. I have very little network
experience.

The gaming laptop connects to our wireless home network and is using 802.11n
but the data speed only gets up to 130Mbps. When I connect the gaming laptop
to the router with a cable it gets 1000Mbps. I thought wireless n would get
up to speeds around 350Mbps. Is there some setting I can change to get more
Mbps? Does the TCP have anything to do with it? (I know nothing about TCP).
It doesn't matter if I am gaming or just surfing the internet the Mbps is
around 130. Any words of wisdom to get this going faster.

Will all wireless PC have to use 802.11n to use my Home network? Perhaps,
any new wireless PC's will have to have their wireless card using WPA2-P &
AES to work on my Home network.

Also, a friend came over with his wireless laptop 802.11g card & use WinXP.
It would not recognize our home network. Does all wireless pc's have to be
802.11n (like my laptop) to use my home network? I was thinking that his
driver for the wireless card was old and if he would get the latest driver
could he change his cards settings to WPA2-P & AES with 802.11g and be able
to connect to the home network. Is that true?

I'm new at networking. Any info will be appreciated. Thanks.

those "350" type speeds are marketing speak. You definitely should
see fast speeds and better range than G. If you don't have any B
devices, change to G/N mode which will improve speed for you.

wired will always be better by far over wireless, even N.

if a computer cannot connect it's probably because it doesn't
support the WPA option you specified. Try WPA-PSK TKIP if you can't
get any of the WPA2 or WPA-PSK AES options to work.

The fastest N speeds for the DIR 655 are with the 1.01 firmware
which allowed a 40MHz channel only. The WiFi Draft 2.0 N certified
firmware revs (1.02 and 1.03) are a little slower due to the changes
in how the 20/40 MHz ruling came down (being a good neighbor).
