1

...

Unable to connect WiFi clients

...

RDKBACCL-1685

...

• This is caused by continuous hostapd restart due to a driver-level crash triggered by the MAC-ACL patch. After excluding this patch for WifiAgent builds, clients were able to connect successfully on every boot.
• Fix: https://github.com/rdkcentral/meta-cmf-bananapi/pull/453

...

2

...

LAN clients are not working after device reboot in Bridge mode

...

RDKBACCL-1755

...

• In bridge mode, LAN clients were not getting IP after reboot because erouter0 was not added to brlan0 as EthAgent started late. After the workaround fix, erouter0 was renamed successfully within 1 minute. But working on the actual root cause for this and those changes will be updated in the next release.
• Workaround Fix: https://github.com/rdkcentral/meta-cmf-bananapi/pull/457/changes
