Only for the record/FYI:
- Winbox 4.x is still experimental, if it works it works, but soemtimes it doesn't.
- Webfig (in version 7.2x.y) has been reported as having sometimes issues.
- In ANY case Quickset (particularly from Webfig, but not only) is re-known to create issues, it should NEVER be run (better) or if you really-really want to run it, ONLY run it ONCE and ONLY after a reset to default configuration, as running it on an already partially custom configured router is a perfect recipe for disaster.
