From: Glen Lee Date: Thu, 4 Feb 2016 09:15:28 +0000 (+0900) Subject: staging: wilc1000: fix WEP security bug X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ec4504832655e8ebc246d3f96efba4b1ea82ecbe;p=openwrt%2Fstaging%2Fblogic.git staging: wilc1000: fix WEP security bug Station cannot connect to soft AP mode wilc when it is configured for WEP security. This patch fixes it by setting the key index within the key value and change the last else condition with DEFAULTKEY action case, and also do not use WILC_WFI_wep_default index to set wep key id.
