# Slow internet. Dropped calls. Find out what’s wrong.

Start with the symptom. Test the connection, keep the evidence, and know what to ask your provider. These guides work without Kilobat, on any device.

[Find your problem](https://kilobat.app/internet-problems#symptoms) [Prepare a complaint with Pro](https://kilobat.app/internet-complaint)

## Find the weak link before changing your plan.

1. **One device?**Compare another device on the same connection.
2. **Only Wi-Fi?**Compare beside the router and over Ethernet.
3. **Only at night?**Repeat the same test at quiet and busy times.
4. **Still unresolved?**Send comparable results and a specific request.

## What is your connection doing?

- [Internet slower than advertised? Test it before you complain](https://kilobat.app/guides/internet-slower-than-advertised): A low speed test is a starting point.
- [Wi-Fi slow but Ethernet fast? Find the wireless bottleneck](https://kilobat.app/guides/wifi-slow-ethernet-fast): If the same device is consistently faster on Ethernet, investigate the wireless path first.
- [Why is my internet slow at night but fast in the morning?](https://kilobat.app/guides/internet-slow-at-night): An evening pattern is useful evidence, but it does not identify the cause by itself.
- [Speed test fast but internet slow? Check latency, DNS and the service](https://kilobat.app/guides/speed-test-fast-internet-slow): A speed test measures transfers to one test service.
- [How to test packet loss when calls freeze or games lag](https://kilobat.app/guides/internet-packet-loss-test): Missing replies can help investigate intermittent problems.
- [Slow internet complaint letter: a template with the evidence to attach](https://kilobat.app/guides/broadband-complaint-letter): A useful complaint says what happened, how you tested it and what you want the provider to do next.
- [Average, advertised and minimum broadband speed: which should you compare?](https://kilobat.app/guides/broadband-average-vs-minimum-speed): The word “speed” can describe a plan, a radio link, a download or a population average.
- [Broadband consumer-rights changes: complaint deadlines and speed evidence](https://kilobat.app/guides/internet-customer-rights-updates): Check the effective date and service type before using a new rule.

Your contract and location determine the process. Start with the relevant local guide.
