Hi Aditya I think by changing PLL control register setting u sud b able to achieve your goal.(also u will require som sw changes) look in reg.h of ath5k /* * PHY PLL (Phase Locked Loop) control register */ #define AR5K_PHY_PLL0x987c #define AR5K_PHY_PLL_20MHZ

Hi, Thanks for your prompt responses. Another member posted some time back that the 'iw' command can set the bandwidth to be 40 MHz in addition to the default 20. So I guess user-level API support is already built in for this kind of change. Don't we just need to extend it's implementation to
