When posting such bug reports, please *always* mention the device and openwrt revision that you're using to provide a proper context.

Also, please check if the issues have been reported already. In this case they have, relevant tickets are #6411, #9654, #11862.

In this case it's also helpful to test a current version. Today I committed something that might help fix some of these issues.
