You need to disable the built-in wireless card from your computer under "Network
Adapters" in the Device Manager.
Card does not perform or connection is slow when computer has a built-in
wired Ethernet card.
This condition occurs if your computer has an active Ethernet card while your
Wireless Card is also active. This happens because Windows must now handle
two active network connections. You need to disable the Ethernet card from your
computer under "Network Adapters" in the Device Manager.
What's the difference between 802.11b, 802.11g, 802.11a, and Pre-N?
Currently there are four levels of wireless networking standards, which transmit
data at very different maximum speeds. Each is based on the designation for
certifying network standards. The most common wireless networking standard,
802.11b, transmits information at 11Mbps; 802.11a and 802.11g work at 54Mbps;
and Pre-N works at 108Mbps. Pre-N, the precursor to the upcoming 802.11n
release, promises speeds that exceed 802.11g, and up to twice the wireless
coverage area. See the following chart for more detailed information.
