I have solved, with openwrt. Now i can set 23dbm, that is the real max power of yhe cpe210.

The real max. power of CPE210 is 27dBm, antenna gain is 9dBi. The CPE510 has maximum real power of 23dBm and its antennas have 13dBi gain.

Both maximum settings (CPE210/CPE510) will give you an EIRP of 36dBm, that is 4,000mW (or to be more precise: 3,981.1mW).

If max. power of the CPE210 is limited to 11dBm in your country, that means that only 20dBm EIRP (11dBm TX power + 9dBi antenna gain = 20dBm EIRP = 100mW) is allowed.

Using 4,000mW in a country where maximum EIRP is limited to only 100mW for very good reasons, this not only could lead to big troubles for yourself, but also the FCC in the US and the regulatory authorities in the EU are reacting by forcing manufacturers to take technical measures which make it impossible to fiddle with TX power at all in the near future.

Even OpenWRT takes such measures to prevent people from abusing TX power settings. See this FAQs:

https://wiki.openwrt.org/doc/faq/faq.wireless#can_i_adjust_the_transmit_power

https://wiki.openwrt.org/doc/faq/faq.wireless#other_transmit_power_issues

and

https://wiki.openwrt.org/doc/faq/faq.wireless#regulation_in_law

So you can set any value in OpenWRT's txpower setting, but wether this will actually work depends on other factors such as the active regdb settings in the kernel used by the CRDA (Central Regulatory Domain Agent) in OpenWRT's firmware.

Same problem with me...is there any way to set more then 11 dbm..?

You have to add the antenna gain to get the total radio emission power. I.e. 11 dBm TX power + 9 dBi antenna gain equals 20 dBm EIRP.

That's what is allowed at maximum by the regulatory provisions for your country.

1. there is no country option on login page at the begining of open web UI
2. There is no country On wireless setting after i open WebUI

It's gone, b/c it is not needed anymore. There are basically only two versions: one for the EU and countries with same regulatory provisions as in the EU and one for the US market and countries with those regulatory provisions.

If you are living in the US and buy gear from the EU or vice versa, you might get the wrong device, yes. Same as with power outlets.

Any news?

Where i can buy this antenna? Can you give me a link?

The news is: it's gone. FCC regulations have been tightened that much, because of the people who didn't care about regulations. Regulation authorities are even discussing to impede access to device parameters for end-users, so that they do not fiddle anymore with settings which can have an impact to the normal operation of other devices sharing the WiFi frequency band.

Look here for the solution:

US region setting actually gives you 16dBm TX power on channels 1 and 11, 20dBm at channels 2 to 10, even if set to maximum displayed in web UI (27dBm):

If set to 27dBm and channel 1 or 11:

[CODE]
# iwlist ath0 txpower
ath0 8 available transmit-powers :
0 dBm (1 mW)
4 dBm (2 mW)
6 dBm (3 mW)
8 dBm (6 mW)
10 dBm (10 mW)
12 dBm (15 mW)
14 dBm (25 mW)
16 dBm (39 mW)
Current Tx-Power=16 dBm (39 mW)
#
[/CODE]

If set to 27dBm and a channel between 2 and 10:

[CODE]# iwlist ath0 txpower
ath0 8 available transmit-powers :
0 dBm (1 mW)
8 dBm (6 mW)
10 dBm (10 mW)
12 dBm (15 mW)
14 dBm (25 mW)
16 dBm (39 mW)
18 dBm (63 mW)
20 dBm (100 mW)
Current Tx-Power=20 dBm (100 mW)
#
[/CODE]

If set to Test mode (HW version 1.0):

[CODE]# iwlist ath0 txpower
ath0 8 available transmit-powers :
0 dBm (1 mW)
9 dBm (7 mW)
12 dBm (15 mW)
15 dBm (31 mW)
18 dBm (63 mW)
21 dBm (125 mW)
24 dBm (251 mW)
27 dBm (501 mW)
Current Tx-Power=27 dBm (501 mW)

[/CODE]
