We are seeing what we perceive to be, less than optimal data throughput rates between the 1142 and the Intel 5300AGN.
Configured as follows:
WiSM w/ 6.0.182.0 code
1142AGN
WPA2-PSK AES
802.11b radio OFF
20MHz channels
WMM Enabled
Dell Latitude E5400
INTEL 5300AGN w/ 13.0.0.107 driver (also tried 12.4.0.21 and 12.4.3.9)
Wireless Zero configuration
RESULTS:
upload = 53Mbps download = 66Mbps
Same TEST with BROADCOM 1505 card:
upload = 73Mbps download = 84Mbps
