WLAN Test Leads to Adapter Agita
Analysis: eWEEK Labs hits some snags while testing the interoperability of wireless LAN gear based on the draft 802.11n spec.Im deep in the process of testing the interoperability of wireless LAN gear based on the draft 802.11n spec. Ive been performing tests using a pair of brand-new Lenovo ThinkPad T60 laptops, each featuring the latest Centrino wireless adapterthe Intel Pro/Wireless 3945ABG. I had intended to use the Centrino adapters as 802.11g clients in my test matrix, but Ive encountered a few problems that may require me to look elsewhere. While preparing the laptops for my tests, by loading up the latest Windows patches and drivers, I noticed that the Centrino adapters consistently crashed my new home network access point, a Netgear RangeMax 240 based on Airgo Networks True MIMO Gen3.
A little research uncovered that this is a known problemthe Netgear router reboots frequently when it receives null QOS (quality-of-service) frames emitted by the 3945ABG. As a temporary workaround, I disabled the clients QOS support to keep the router functional.
