i need to manual change channel from #1 to another one but i can't do that. when i go to Basic network -> Wireless i can chose from auto to manual but when i go to Status -> Wireless section i see that use #1 channel only and always.
did you click save after making your channel selection?
Change the mode to "access point" and save. Then change the channel and save. When you switch back to the client mode you are using the channel change will be effected. I think it might be a bug.
surely i press save button. after some research i think that channel number is dependent of WLAN mode (B/G/N) coz in some mode channel is change and in other is not. think that this is some dependence between mode and range of channel.
