All of the country-specific regulatory constraints are burned into EEPROM on the device. Intel makes several different geographic SKUs. MOW(Most of the World) SKU supports channel 1-11. Only Japan and Korean SKU support 1-13.
Both uCode and driver should be looking at that data to scan the right channels. Looks like currently the iwk driver is not looking at that information. When that feature is incorporated into the driver, it should be able to scan the legal channels in the geographic SKU that it is meant for. -Geeta >-----Original Message----- >From: laptop-discuss-bounces at opensolaris.org [mailto:laptop-discuss- >bounces at opensolaris.org] On Behalf Of Michael Li >Sent: Tuesday, July 01, 2008 2:03 AM >To: Matthew Gardiner >Cc: laptop-discuss at opensolaris.org >Subject: Re: [laptop-discuss] Wireless Channels > > >Matthew Gardiner ??: >> 2008/7/1 Michael Li <Mikore.Li at sun.com <mailto:Mikore.Li at sun.com>>: >> >> Zhonghui, >> >> Additionally, I just found Intel4965 could scan out the AP set to >> channel 13 under WinXP. >> >> >> Same thing can be done with the WPN311 card as well on Windows XP - >> infact, IIRC, it is the same chipset as the previous generation >> MacBook uses which I used to connect to my Airport extreme at channel >> 13 to avoid collision with the neighbours. >> >> All these devices can do it - I doubt they would make a special >> 'japanese chip' and 'chinese chip' and 'european chip' - it would be >> hugely expensive and pointless when all this could be set using a >> combination of driver and firmware. >Under Windows platform, WiFi adapter's working channels are region >related, you can find different channel sets for different region in >driver INF file(such as bcmwl5.inf).
