- just bought this awesome router
- RT-N66U updated to merlin firmware 220.127.116.11.266.23b
- bought and is using this router in Singapore (APAC)
- default transmit power 80mw
- want to attain max transmit power 500mw
- but max transmit power 200mw:
"Set the capability for transmission power. The maximum value is 200mW and the real transmission power will be dynamically adjusted to meet regional regulations"
- tried to change the timezone of the router, doesn't work.
- doesn't custom firmware bypass all these restrictions? please help!
Update 22 July 2013:
This is just for those who are INTERESTED to test out 500mw transmit power on their RT-N66U, you may enter commands via GUI at 192.168.1.1 > Tools > CMD
or via telnet
### To CHECK your current region, each line entered will result in the answer.
nvram get pci/1/1/ccode
nvram get pci/2/1/ccode
nvram get wl0_country_code
nvram get wl1_country_code
nvram get regulation_domain
nvram get regulation_domain_5G
### To ALTER to a new region such as US(500mw), or GB(200mw), enter or change the last 2 letters accordingly to each line. Its a good idea to CHECK your current region after each command entered.
nvram set pci/1/1/ccode=US
nvram set pci/2/1/ccode=US
nvram set wl0_country_code=US
nvram set wl1_country_code=US
nvram set regulation_domain=US
nvram set regulation_domain_5G=US
### To CHECK your current transmit power, each line entered will result in answer.
nvram get wl_TxPower
nvram get wl0_TxPower
nvram get wl1_TxPower
### To ALTER to a new transmit power such as 500mw(US) or 200mw(GB), enter or change the last 3 digits accordingly to each line. Its a good idea to CHECK your current transmit power after each command entered.
nvram set wl_TxPower=500
nvram set wl0_TxPower=500
nvram set wl1_TxPower=500
After nvram commit command is entered, you may additionally VERIFY values at the GUI > Wireless > Professional > Tx power adjustment. Take note your router temperature MAY rise by about 2 to 3°C and maintain. I have experienced only a 5% average strength increase from 200mw to 500mw. FYI, firmware using is by Merlin 18.104.22.168.372.30_3. Signal strength check using WiFi Explorer 1.5.1.
