Wireless issues with T61 4965AG and 4965AGN

2008-05-08, 21:58 PM
Isssue: certain areas of 2nd floor three story building might as well be dead zones for this adapter. British Telecom and Cisco have been there to address any environmental concerns. Both have made their adjustments to no avail. The adapter dies in this area and will not find AP eventhough I'm directly underneath. I have tried all adjustments (power management, roaming agressiveness, b and g only, g only etc., radio transmit power) nothing works. I use custom build or IBM Preload with Access Conn with newest drivers but still get same results. Netstumbler logs sent out and response was 4965 detects twice as many APs as 3945ABG and therefore more sensitive to signals.
 
Issue has been escalated to Intel/Lenovo/IBM but in the meantime the solution is to switch to the 3945ABG (works like a charm compared to 4965 series)
 
Anyone else in the universe have any similar experiences???

What did they find in terms of environmental concerns, and what adjustments did they make?
 
Also what wireless access point are you using?
 
Cheers,

For environmental concerns we looked at air cond, what type of building materials used in walls and any other type of generators or electronic equipment that could cause interference. We checked conf rooms, break rooms and conf rooms used as PC labs. Netstumbler picked up peer-to-peer and public WiFi APs but we couldn't find obvious interference. Since the 3945ABG performed well we are believing the 4965AG/AGN needs work.
 
Cisco/BT adjusted AP radio signal power to lowest level to balance the sensitivity of the adapter.
