Internet keeps disconnecting every few minutes
Regular drops have three common causes: a marginal fibre/optical link, a router overheating in a cabinet, or a device roaming between two access points. The pattern tells you which - a drop every 5 minutes looks like line flapping, while a drop when you walk upstairs is roaming.

Do this, in order
- Note the time between drops; if it is consistent, it is almost always line-level, not your laptop.
- Touch the router: hot units throttle and drop. Add airflow or move it out of the cupboard.
- Check for an old firmware banner in the router admin page (192.168.1.1 for most du units).
- If you have two SSIDs from one router or an extender, name them apart and pin the important device to the router itself.
- Ask for an optical power reading on the fault ticket - dBm out of range means a splice or patch problem, not a settings problem.
