FS#3913 - On WAC124, the frrequency database is no read correctly

[openwrt-bot]

mzn:

Apologies for not reporting this sooner - it has been true for the last
several months of beta's and for rc3.

When choosing a frequency for 5ghz for the Netgear WAC124:
[1] an incomplete list is given (nothing above channel 144)
[2] changing the width (20/40/80) does not affect choices
[3] NO choice will work except ch 36. Any other choice will be
accepted but the radio will be disabled - in GUI and in reality.
[4] Ch 36 does work fine

This has been true whether access the device from Mac/Linux or Windows,
Firefox or Chrome, so suspect base package issue (as opposed to GUI), but
not sure.

In case this helps any:
Netgear GUI allows any non-DFS channel (as appropriate for bw) up to 165
dd-wrt gui allows all (dfs/non-dfs) (as appropriate for bw) up to 165

Note that the WAC124 is limited to 100mw (great for AP, as often < $55).

I've 3 of them, so can test as desired.
I've saved the partitions (eg: factory) in case that is useful for anyone.
