Hello,
I have a "Intel(R) Centrino(R) 1030 BGN" card. tx_power_device_lmt is 15
and I was wondering if the card could do more than that.
the card should not and will not do more than what required by
regulatory
I'm allowed to do 20dBm here and was wondering if I could make the card do
that.
the tx power in Intel WiFi device is regulated by uCode to make sure we
are within regulatory limits. What country you are in?
Thanks
Wey
I am also having the same issue with my Intel PRO/Wireless 5100 AGN.
Here in Germany I'm allowed to use 20 dBm (in the 2.4 GHz band), but the
card is limited to 15 dBm. So in some situations other cards are working
fine (as they use 20 dBm) and the Intel can't establish a connection.
We do not have different SKUs for different regions of the world. Now I
understand your problem. Thank you very much for reporting. I will raise
the issue and see how we should fix it.
Sorry, I don't have a solution for you today. But it is very important
for us and we need to result it.
Thanks
Wey
Is there any news?
Hi, I talk to the marketing and since we are providing single SKU
solution, the maximum allowed tx power is programmed in EEPROM, so
currently there is no method to allow use the higher limitation.
Thanks
Wey
According to [1] there are no countries that forbid tx power values
lower than 20dBm in the 2.4 GHz band. The lowest value for the 5 GHz
band listed is 17 dBm. So why are the Intel cards limited to 15dBm then
for both bands? This value absolutely makes no sense in my view.
