The problems started +with kernel 4.2, which is the first version that had commit d10101a60372 +("rtlwifi: rtl8821ae: Fix problem with regulatory information"). With this +patch, the driver went from setting a default channel plan to using +the value derived from EEPROM. + +Bug reports at https://bugzilla.kernel.org/show_bug.cgi?id=111031 and +https://bugzilla.redhat.com/show_bug.cgi?id=1279653 are examples of this +problem. + +The problem was solved once I learned that the internal country code was +resulting in a regulatory set with only 2.4 GHz channels. With the RTL8821AE +chips available to me, the country code was such that both 2.4 and 5 GHz +channels are allowed. The fix is to allow both bands even when the EEPROM +is incorrectly encoded. + +Fixes: d10101a60372 ("rtlwifi: rtl8821ae: Fix problem with regulatory information") +Signed-off-by: Larry Finger +Cc: littlesmartguy@gmail.com +Cc: gabe@codehaus.org +Cc: Stable [v4.2+] +--- + drivers/net/wireless/realtek/rtlwifi/regd.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/drivers/net/wireless/realtek/rtlwifi/regd.c b/drivers/net/wireless/realtek/rtlwifi/regd.c +index a62bf0a65c32..5be34118e0af 100644 +--- a/drivers/net/wireless/realtek/rtlwifi/regd.c ++++ b/drivers/net/wireless/realtek/rtlwifi/regd.c +@@ -351,7 +351,6 @@ static const struct ieee80211_regdomain *_rtl_regdomain_select( + case COUNTRY_CODE_SPAIN: + case COUNTRY_CODE_FRANCE: + case COUNTRY_CODE_ISRAEL: +- case COUNTRY_CODE_WORLD_WIDE_13: + return &rtl_regdom_12_13; + case COUNTRY_CODE_MKK: + case COUNTRY_CODE_MKK1: +@@ -360,6 +359,7 @@ static const struct ieee80211_regdomain *_rtl_regdomain_select( + return &rtl_regdom_14_60_64; + case COUNTRY_CODE_GLOBAL_DOMAIN: + return &rtl_regdom_14; ++ case COUNTRY_CODE_WORLD_WIDE_13: + case COUNTRY_CODE_WORLD_WIDE_13_5G_ALL: + return &rtl_regdom_12_13_5g_all; + default: +-- +2.5.0 +
