And yes, if you have already installed the 8192cu driver, then you dont have to do step. This entry was posted in Memo on Novemby henry. Yes, you can skip part (2) - it is only needed for raspberry pi. I do not find any wrong using the old rtlwifi driver so far, but if you wanna recover to the original driver, just comment the blacklist in the nf. Then you can compile the kernel, after that, you have to add the 8192cu to blacklist avoiding the supplied driver. Of course you can change it to any value reasonable. So the value I changed will make them to use all 14 channels available worldwide and to use a maximum dBm of 33 (what is about 2000 mW). I presume therefore that the chip is RTL8812BU. REG_RULE(min_freq, max_freq, kHz, max_dbm_with_antenna, max_dbm, flags) The drivers on the mini-CD are for RTL8812BU and RTL8811CU. The REG_RULE function is defined as follow: Take advantage of the Raspberry Pi and Beagle Bones USB port to add a low cost, but high-reliability wireless link. The easiest way is to modified the world standard definition in the driver.

Cause of that the card will only have channels 1 to 11 and runs at maximum 20 dBm. The rtlwifi driver ignores the regulatory set by the CRDA service. #source “drivers/net/wireless/rtlwifi/Kconfig” Fixing the regulatory domain (CRDA) ![]() Uncomment this line in drivers/net/wireless/MakefileĪlso uncomment this line in drivers/net/wireless/Kconfig ![]() The only way to solve it is to build your own kernel… (T▽T)įollow the raspberry manual to build kernel, notice you should change some files before compiling. ![]() SET failed on device wlan0 Invalid argument. The result is you can not use monitor mode any more.Įrror for wireless request "Set Mode" (8B06) : Is added and rtlwifi is disabled for stabilization. The rtlwifi(for Wifi chips such as those based on Realtek’s 8192cu) is the upstream driver and rtl8192cu is the out-of-stream driver, and the rtlwifi driver seems to be rather unstable on the Raspberry PI (It works fine on x86 machines), so it doesn’t generally get included in most distributions, in the commit 6d4d3a978afbc332af02e548bd0e8ced16dff296 non-mainline source for rtl8192cu wireless driver
