Only few channels work in 5Ghz band in Openwrt[Solved]

Only 36,40,44,48 are working in 5Ghz band. When i try for other channels router hang for some time and go back to 36. Same thing happens when i try for bonding in 40Mhz channel. Any help would be appreciated.

These are the only channels guaranteed to work (according to international standards).

Other channels are either limited by DFS (aka radar detection) or limited power.

The following link lists the channel allocations and their use, by country/region and is pretty much up to date.

For example if you want 40MHz bandwidth, choosing channels 38 or 46 will generally work if you comply with regional transmit power restrictions (TPC). eg in Europe a max power of 200mW is allowed. Other 40MHz channels will be subject to either/both DFS and TPC
