If using shell, then the only modified file is `/etc/config/wireless` (see below), next run `wifi` to bring wireless up.\r\n\r\n0) No wireless clients.\r\n1) Do: client A - connect to 2.4 GHz\r\n2) Do: client B - connect to 2.4 GHz\r\n3) Do: client A - disconnect from 2.4 GHz\r\nResult: client B - goes offline\r\n\r\nOffline means client is associated, wireless connected, but no ping to router. No new lines in `syslog`, `iwinfo wlan0 assoclist` shows client normally, ping to router doesn't bring connection up.\r\n\r\nIf you wait for 10 minutes here, connection of client B is recovered (WPA rekeying GTK). See all logs below.\r\n\r\nTest can be continued:\r\n4) Do: client A - connect to 2.4 GHz\r\nResult: client B - back online.\r\n\r\nSame can be done with 5 GHz on both clients with same result. Encryption is required for this issue. If encryption is disabled, then no issue. How can I fix this?\r\n\r\nContents of the only modified file `/etc/config/wireless`:\r\n```\r\nconfig wifi-device 'radio0'\r\n        option type 'mac80211'\r\n        option channel '11'\r\n        option hwmode '11g'\r\n        option path 'soc/soc:pcie-controller/pci0000:00/0000:00:02.0/0000:02:00.0'\r\n        option htmode 'HT20'\r\n        option country 'DE'\r\n\r\nconfig wifi-iface\r\n        option device 'radio0'\r\n        option network 'lan'\r\n        option mode 'ap'\r\n        option encryption 'psk2+ccmp'\r\n        option key 'password'\r\n        option ssid '24GHz'      \r\n                              \r\nconfig wifi-device 'radio1'   \r\n        option type 'mac80211'                                                    \r\n        option channel '36'                                                       \r\n        option hwmode '11a'                                                       \r\n        option path 'soc/soc:pcie-controller/pci0000:00/0000:00:03.0/0000:03:00.0'\r\n        option htmode 'VHT80'\r\n        option country 'DE'   \r\n                              \r\nconfig wifi-iface             \r\n        option device 'radio1'\r\n        option network 'lan'    \r\n        option mode 'ap'        \r\n        option encryption 'psk2+ccmp'\r\n        option key 'password'\r\n        option ssid '5GHz'\r\n```\r\nCross-post: https://forum.openwrt.org/viewtopic.php?pid=276764#p276764"},"comment":{"url":"https://api.github.com/repos/kaloz/mwlwifi/issues/comments/125354091","html_url":"https://github.com/kaloz/mwlwifi/issues/20#issuecomment-125354091","issue_url":"https://api.github.com/repos/kaloz/mwlwifi/issues/20","id":125354091,"user":{"login":"DavidMcWRT","id":9170151,"avatar_url":"https://avatars.githubusercontent.com/u/9170151?v=3","gravatar_id":"","url":"https://api.github.com/users/DavidMcWRT","html_url":"https://github.com/DavidMcWRT","followers_url":"https://api.github.com/users/DavidMcWRT/followers","following_url":"https://api.github.com/users/DavidMcWRT/following{/other_user}","gists_url":"https://api.github.com/users/DavidMcWRT/gists{/gist_id}","starred_url":"https://api.github.com/users/DavidMcWRT/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/DavidMcWRT/subscriptions","organizations_url":"https://api.github.com/users/DavidMcWRT/orgs","repos_url":"https://api.github.com/users/DavidMcWRT/repos","events_url":"https://api.github.com/users/DavidMcWRT/events{/privacy}","received_events_url":"https://api.github.com/users/DavidMcWRT/received_events","type":"User","site_admin":false},"created_at":"2015-07-27T21:58:29Z","updated_at":"2015-07-27T21:58:29Z","body":"@yuhhaurlin\r\n\r\nUpdate F/W to version 7.2.8.6. …\r\n\r\nFix issue #20.\r\n\r\nA quick test seems to indicate this fixes the problem on WRT1900AC v1 for me, at least on 2.4GHz.
