ER605 v2 Router Constant 100% CPU USAGE
Our office router ER605 suddenly became unresponsive due to high cpu usage thus affecting our internet. even with little to no internet activity the problem still persist. I've tried restarting and completely turning it off for a few minutes but the problem still persists. I hope you can help me resolve this problem as soon as possible to avoid very long downtime. Thank you

In case the problem is caused by some function on the router, try resetting the router and testing it again.
You can also upgrade the firmware of the router to the latest one ER605(UN)_V2_2.0.1 Build 20220223 to test.

@Virgo I have a feeling that it is L2TP is the root cause of this issue.Prior this constant high cpu usage, I have already encountered intermittent 100% cpu usage every few seconds whenever L2TP is enabled, but when i try to disable it and restart the router the issue seems to disappear.
