The older Turris routers (versions 1.0 and 1.1) still have some of the most powerful hardware available today. The only thing they lack in is modern Wi-Fi hardware. They do not permit a 2,4 and 5GHz bandwidth simultaneously, because they only support 802.11 a/b/g/n standards. To bring also our older models up to date, we have prepared the Wi-Fi Upgrade Pack for our Turris 1.x users. The package has a price of 1600CZK and will bring you up to the 802.11ac standard, that is the fastest available wireless connection.
You can have a look at the precise contents of the WiFi Upgrade Pack and buy it at the Discomp webshop.
The Wi-Fi Upgrade pack is for Turris 1.x routers and not for Turris Omnia. Turris Omnia has 802.11ac Wi-Fi from the factory.
