I have noticed that my laptops wireless speed is literally rubbish. My roommate uses a Macbook Pro and his download speeds reached 330kb/s while mine were barely hitting 6kb/s. These wide spans in connection speeds have been going since I bought my laptop about 5 months ago.
My values are normal and as follow:
802.11b Preamble - Long and Short
AdHoc 11n - Disabled
Network Address - Not Present
Receive Buffers - 256
Scan Valid Interval - 60
Transmit Buffers - 512
Wep TKIP11n - Enabled
Wireless Mode Selection - Auto
IPv4 Connectivity : Internet
IPv6 Connectivity : No Internet Access
My driver is 8.0.0316
