Unable to get the specific AP info via "iwlist wlan0 scanning"

nakoruru
Hi, i have a router with wireless on,and i want to get the ap information via "iwlist wlan0 scanning".
BTW,i stop the ubuntu Network-manager service in order to connect to the ap manually, but seems the scan result does't contain the ap info i want. meanwhile, the cellphone can get the router ap info.
i start Network-manager service again,and the Network-manager doesn't find the ap info of the router too.
the kernel of ubuntu is 6.30 and the madwifi driver is madwifi-trunk-r4132-20100620.

Does anyone encounter same questions? could you give some advice? i try to reboot the PC or router, but it doesn't work.

i got some new informations. but also got some new questions.

1.when the ap is in the 13 frequency band, i can't get the ap info via iwlist scanning. which is very weird.

2.Given that the i get the ap info of my router which is in frequency band 1, then i change the router to frequency band 13, but when i execute "iwlist wlan0 scanning" , i still find that the ap is in frequency 1. i guess the wifi doesn't "really" scan the ap around but instead,it just get the result from cache, if it's true, how to clean the cache and make the wifi do a "real" scanning.
