I would like to enhance the TX power of my TomatoUSB/Shibby access point (running on Asus RT-N66U) within 5 GHz band.
In Germany/Europe we are allowed to set TX rates at up to 1 watt under specific circumstances (see german wikipedia article for IEEE_802.11h as I can't paste the link here).
As one can see if you use channels 100-140 (5,470…5,725 GHz) transmit power can be blown up to 1000 mW (30 dbm EIRP) if you use DFS and TPC. That way one could have comparable distance reach similar to 2.4 GHz usage (but without a lot of interferences in metropolitan areas).
How exactly do I configure this in TomatoUSB?
My current 5 GHz settings:
Wireless Mode: Access Point Wireless Network Mode: N Only Channel: Automatic Channel width: 40 MHz Control sideband: upper Security: WPA2 Personal Encryption: AES Afterburner: Disable AP Isolation: Disable Basic Rate: All Beacon Interval: 100 CTS Protection Mode: Disable Regulatory Mode: Off Country /Region: EUROPEAN UNION Bluetooth Coexistance: Disable Distance / ACK Timing: 0 DTIM Interval: 1 Fragmentation Threshold: 2346 Frame Burst: Disable Maximum Clients: 128 Multicast Rate: Auto Preamble: Long 802.11n Preamble: Auto Overlapping BSS Coexistance: Off RTS Threshold: 2347 Receive Antenna: Auto Transmit Antenna: Auto Transmit Power: 400 Transmission Rate: Auto Interference Mitigation: WLAN Auto with Noise Reduction WMM: Enable WMM No ACK: Disable WMM APSD Mode: Enable Wireless Multicast Forwarding: Enable
I played with settings Channel and Country/Region combinations but basically Auto Channel does not end within 100-140 range (with DFS and TPC enabled) but channel 36 or 40. If I set Country to Norway (as most less restrictive country in Europe I read somewhere) I can manually choose channels 104/112/120/128/136 and my Mac shows DFS activated in advanced WLAN settings (but no TPC) which is a bit strange because I understood automatic channel selection should end up with active DFS settings, right?
How about Regulatory Mode, do I need to turn this on to have expected behavior with 1 Watt maximum transmit power?
Thanks anybody for helping me out :-)
