# Ubuntu 16.04: Wireless / WiFi is slow

## post by mpb on Jul 5, 2018

Ubuntu has notoriously buggy Wireless / WiFi drivers. The most typical cause of slow wireless is Ubuntu’s 802.11n driver. Disabling this drive resolves the problem.

**Temporary fix (not preserved between reboots):**

```
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi 11n_disable=1
```

Now, [run speed test](http://www.speedtest.net/). If issue is resolved, do the “Permanent Fix.”

**Permanent fix:**

```
echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
```
