# My broadband is slower than I pay for

Wifi almost always gives a lower speed than the line, so measure with a cable before you look for faults. Start with the cause at the top, it is the most common.

## Common causes

### 1. You’re measuring over wifi or through the router

**Check:** Is the computer you measure with connected over wifi or through the router?

**What to do:** Connect a computer with a cable directly to the fibre box, without a router and without wifi. Measure with [Bredbandskollen](https://bredbandskollen.se) and save a screenshot of the result.

### 2. The speed stops at about 100 Mbit/s

**Check:** Do you measure around 100 Mbit/s although you pay for more, even with a cable? It can happen after a power cut.

**What to do:** Use a Cat5e or Cat6 cable and a computer whose network card handles gigabit. Then restart the fibre box.

A cable, network card or router that only handles 100 Mbit/s locks the speed there.

### 3. You recently changed to a higher speed

**Check:** Have you restarted the fibre box and the router since the change?

**What to do:** Restart the fibre box and the router. The new speed only applies after a restart.

### 4. It’s slow even with a cable directly in the fibre box

**Check:** Does the test with a cable directly in the fibre box show less than half the speed you pay for?

**What to do:** Then it may be a fault in the network. Report a fault and include the screenshot from the test.

## Good to know

- If it’s fast with a cable directly in the fibre box but slow through the router, the router or wifi is the limit.
- Wifi on 5 GHz is faster than 2.4 GHz. Distance, obstacles and interference lower the speed.
