Intel Centrino Advanced-N 6205 wireless

Intel PROSet/Wireless

version 2012/06/05, Lenovo Thinkpad T430s (intel has 15.1.1 2012/05/03 already for IT administrator

no documentation for v15 (or v14)?, only for v13?

Connection Utility


Cisco Linksys WRT610N v1 2009/07/28 Ver. firmware


TRENDnet TEW-692G (now N900) 2011/08/01 1.0.01 firmware ( 2012/05/18 now available)

shows connect using 802.11n band, software shows 802.11a with only up to 54Mbps data rate

even AP said connect at 270Mbps

and it achieves 19MBps (resource monitor) and 61% utilization (taskmgr) with 300Mbps connection over SMB using LAN GigE port to NAS

Help said software can show 802.11n and 300Mbps (and 450 for tri band)

Even turn off 802.11a in Linksys or Trendnet, Wireless-N only for 5GHz (or force 40MHz channel width, manaual wide channel)

connect screen still shows 802.11a and 802.11n

changing security from open to WPA2 AES makes no difference (other security only allows 54Mbps)


Transmit/Receive has no high throughput (online document said that happens when it think it is connected to legacy instead of 802.11n AP)

6205 in T420s (software version ) has an extra section

Advanced Statistics sometimes shows only 25.0mW instead of 32 mW?


turn on Ad-hoc QoS WMM and enable QoS on router makes no difference

turn off power manager makes no difference

Power Manager

turn on maximum performance in Lenovo power manger makes no difference
