My B1300 is using firmware 3.105. I downloaded sqm-scripts and luci-app-sqm and configured it for eth0. However, it doesn’t seem to be working as the test results from bandwidth testing consistently exceed the limit I’ve set.
Looking at the system logs, I noticed the following errors, any thoughts on what it might be? Looks like an installation error, but I’ve reinstalled and rebooted several times already.
