This article is for users of Turris Omnia only
Basic Wi-Fi settings can be done in the Foris user interface. If you want to set up Guest Wi-Fi, see our manual on how to do that under Guest Wi-Fi.
The Turris Omnia router has two Wi-Fi cards. One of them is for Wi-Fi networks in the 2.4GHz bandwidth and the second can send out 2.4GHz as well as 5GHz bandwidth, it is however recommended to mainly use it for 5GHz. If you use both cards for 2.4GHz, it will cause interference, because they share antennas. So, in case you want to use the switchable dual band card for 2.4GHz, you will need to connect it to the right point on the diplexer. We however don‘t recommend this hack for everyday use.
Enable one of the Wi-Fi cards to open its specific settings. The picture below shows the settings for the 5GHz card. You can tell, which card you are doing the settings for, simply from the Wi-Fi mode
item – the 2.4GHz only card doesn‘t have this option.
802.11n - 40MHz wide channel
. If you are doing settings for the 5GHz Wi-Fi, try the 802.11ac - 80MHz wide channel
.If you enable the second card, you can also set it up. However, you can also just enable one of the cards. Don‘t forget to save your settings.
If the Wi-Fi speed doesn‘t reach expected results, try to check, if the pigtails to the Wi-Fi cards are connected correctly. The following picture shows how the components were originally connected from the factory.
It is necessary to pay special attention to how the pigtails are connected to the diplexers. The blue connector has to be linked up to the small 2.4GHz card, the connector that is circled red should be linked up to the bigger 5GHz card.
