Wireless performance with IEEE* draft 802.11n is based on a variety of factors. The most important factors to take into account when trying to connect at higher speeds with the Intel® Wireless WiFi Link 4965AGN are as follows:

1. MIMO (Multiple-In Multiple-Out)
2. Channel bonding
3. Frequency (2.4GHz or 5GHz)
4. Wireless Router

MIMO allows the use of multiple spatial channels for data transmission and reception increasing the data throughput in direct correlation to the number of antennas used. The Intel® Wireless WiFi Link 4965AGN has 2 transmitters and 3 receivers to support MIMO.

Channel bonding must be supported on both the client and wireless router. Using two channels increases the amount of information that can be sent over the wireless connection. For example a two lane highway can accommodate more cars than a one lane highway.

Intel recommends 5GHz channel bonding. Your wireless router should support 5GHz (802.11a) to implement channel bonding as recommended. 

Router manufacturers support different versions of draft 802.11n. The current draft 2.0 version includes support for features such as short guard interval and frame aggregation. Lack of support for these features can reduce the maximum rate and reduce performance of the Intel® Wireless WiFi Link 4965AGN. The Connect with Intel® Centrino® program tests and verifies routers.
