Generally speaking, the 5 GHz band has substantially greater capacity due to more non-overlapping radio channels and less radio interference as compared to the 2.4 GHz band.

## <a name="docker"></a>What breaks RaspAP when Docker is installed on the same system and how I can fix it?
Installing RaspAP after installing Docker often results in connected clients not having internet access from the AP. The reason for this is Docker manipulates `iptables` rules to provide network isolation. Docker installs two custom iptables chains named `DOCKER-USER` and `DOCKER`, and it ensures that incoming packets are always checked by these two chains first. Docker also sets the policy for the `FORWARD` chain to `DROP`. When RaspAP is started in its default router mode, this will result in the AP not forwarding any traffic anymore. If you want RaspAP to continue functioning as a router, you can add explicit `ACCEPT` rules to the `DOCKER-USER` chain to allow it:
`sudo iptables -I DOCKER-USER -i src_if -o dst_if -j ACCEPT`
Additional info [here](https://docs.docker.com/network/iptables/).

We have provided an uninstall script to remove RaspAP cleanly, and also restore any backups of your configuration that were created before RaspAP was installed. The uninstall script is located in `installers/uninstall.sh`. To start the uninstaller, simply run the following from the project root folder (default location is `/var/www/html`): We have provided an uninstall script to remove RaspAP cleanly, and also restore any backups of your configuration that were created before RaspAP was installed.
