#20201: TL-wdr4900 max txpower for country BG (Bulgaria)
-------------------------+----------------------------------
Reporter: vlado@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Chaos Calmer (trunk)
Component: base system | Version: Trunk
Keywords: |
-------------------------+----------------------------------
Recently I build CHAOS CALMER (Chaos Calmer, r46494)
uname -a
Linux wdr4900 3.18.19 #2 Sun Jul 26 02:43:17 EEST 2015 ppc GNU/Linux
The problem is max txpower for both radios (2.4/5GHz) when country is set
to BG.
I can't set more than 16 dBm (39 mW) for 5GHz and 18 dBm (63 mW) for
2.4GHz.
If you need more info just ask.
