I did a clean install of windows 7 last night and the first thing I did was install 17.0.3.2. So I know that there is no other version of the drivers on the computer. And today at my College campus it still read only 54Mbps. Before 17.0.3.2 it would always connect at 300Mbps. There is something wrong with this drivers now that I have installed these drivers it will not connect at 300Mbps. if I could get that speed with 17.0.2.5 then that tells me that it is something with the drivers. I have even tried at a public library that was an open network no WiFi security setting and still only go 54Mbps. I know that my card is dual band because at the library I could see there 5Ghz network and connect to it.
I will say this again My college Campus uses WPA2-Enterprise and the public library used no Security settings.
I also do not know how to force to use 802.11A as I said above that I could see and connect to the 5Ghz and with my College campus's network if it sees you have A capability it automatically give you 300Mbps.
This come from my college talking about the network.
Securewireless uses 802.11i technology, commonly known as WPA2. WPA2 along with 802.1x, relies on the wireless client’s ability to authenticate onto a network with a username and password and then encrypts the data with the Advanced Encryption Standard (AES). UCIT enabled WPA2 wireless security on access points in January, 2008, and has included WPA2 security on all access points installed since then.
After a wireless user performs the initial setup for Securewireless on their wireless device, they then need to user their Central Login Credentials (CLS) to gain access to the wireless network. There are two WPA2 standards available, WPA2-Personal and WPA2-Enterprise; WPA2-Personal is designed for home use. UCIT recommends that all new wireless devices support the WPA2-Enterprise standard.
Users wishing to implement WPA2 must have a supplicant on their wireless device that supports 802.1x. Windows XP SP3, Vista, 7 and 8 natively support 802.1x authentication, as well as MAC OS X 10.3 and above. Versions of 802.1x are readily available for download for Linux devices. Users will need to follow the detailed directions posted on the UCIT web page to configure their 802.1x supplicant for access to the wireless network.
All new external, internal and USB wireless cards must have WPA2 Enterprise certification. It is also recommended that all new wireless cards support a/g/n. Wireless cards designated b/g/n will only connect at g speeds on the UC wireless network due to the physical limitations of the b/g band.
