Dear John: Recently I test IBSS WPA-NONE use rtlwifi driver, it can link successfully, but can not ping. And I found that receive packet from other non-mac80211 peer have been decryped by rtlwifi hardware like RTL8188CE, but these packets will be discard by follwing code in ieee80211_rx_h_decrypt: ============================================================== /* * RSNA-protected unicast frames should always be * sent with pairwise or station-to-station keys, * but for WEP we allow using a key index as well. */ if (rx->key && rx->key->conf.cipher != WLAN_CIPHER_SUITE_WEP40 && rx->key->conf.cipher != WLAN_CIPHER_SUITE_WEP104 && !is_multicast_ether_addr(hdr->addr1)) rx->key = NULL; ============================================================== because not only WEP, but IBSS WPA-NONE will also use Group for both receiving and sending unicast and multicast packets. So I want to ask, why we can't receive WPA-NONE packets here ? Will WPA-NONE packets cause other issues ? Thank you for your help.
