To force your Vodafone router onto 2.4GHz, you split the two frequency bands into separate Wi-Fi networks (SSIDs) so your devices can connect to whichever band you choose. The whole process takes about five minutes inside the router admin page.
Smart home devices are the main reason. ESP-based gadgets, Tapo plugs, and most budget IoT hardware only support 2.4GHz. When your router broadcasts a single combined network, those devices sometimes latch onto 5GHz and then fail to connect. Separating the bands removes that guesswork entirely.
The trade-off is speed. 2.4GHz has longer range but lower throughput. For a smart plug or a sensor, that is fine. For a laptop streaming 4K, stick to 5GHz.
Make sure you are connected to your Vodafone Home Broadband network, then type http://192.168.1.1/ into your browser's address bar. If the page does not load, check you are on Wi-Fi or ethernet from the Vodafone router rather than a mobile connection.
The default password is vodafone (all lowercase). If you have changed it and forgotten it, a factory reset will restore the default, though that will wipe your custom Wi-Fi name and password too. The username field, where present, is usually left blank or set to "admin".
Go to the Wi-Fi tab, then select General Wi-Fi settings. You will see an option to split the two bands. As Vodafone's own support document puts it: "If you don't want a device to automatically select which band to connect to, you can split the 2.4GHz and 5GHz bands into two separate SSIDs."
On the Vodafone Power Hub specifically, splitting the network creates two visible networks: your original SSID stays as the 2.4GHz network, and a new SSID with a _5ghz suffix appears for the faster band. Give the 2.4GHz network a name you will recognise, such as "HomeNetwork_2.4G", so you can point your smart home devices to it without confusion.
For this you need Expert mode. Inside the Wi-Fi tab, enter Expert mode and go to Settings. Here you can change the Wi-Fi mode, channel width, and channel number for each frequency independently.
For 2.4GHz, channels 1, 6, and 11 are the non-overlapping options. Picking one of those, rather than leaving it on "auto", reduces interference from neighbours' routers. Channel width of 20MHz on 2.4GHz is more stable for IoT devices than 40MHz.
Save your changes, then reboot the router. Now connect your smart home devices to the 2.4GHz SSID only.
One thing to be aware of: some users on SNBForums report that ESP devices on a secondary 2.4GHz SSID can take hours to reconnect after a router reboot. If you have four or more of these devices, check each one manually after the router comes back up rather than assuming they have all rejoined automatically.
Run through this short checklist before calling Vodafone support:
SNBForums users who made the switch generally found ISP routers handle 2.4GHz devices well. One user ran ESP devices reliably on a Vodafone router for 18 months after having done the same on a Sky router for two years previously, with no meaningful difference in stability once the bands were properly separated.

Log in with the default password 'vodafone' (all lowercase). If the page won't load, check you're connected via Wi-Fi or ethernet from the Vodafone router, not a mobile connection. ### can I split 2.4GHz and 5GHz on Vodafone router Yes, you can split the bands into two separate SSIDs in the Wi-Fi settings. According to Vodafone's official support, this prevents devices from automatically selecting the wrong band. On the Vodafone Power Hub, splitting creates your original SSID on 2.4GHz and a new SSID with a '_5ghz' suffix for 5GHz devices. ### why won't my smart home devices connect to Vodafone router Most budget smart home devices like ESP-based gadgets and Tapo plugs only support 2.4GHz. When your router broadcasts both bands together, these devices sometimes connect to 5GHz instead and fail to work. Splitting the bands into separate networks solves this by letting you force smart devices onto 2.4GHz only. ### what's the default password for Vodafone router admin The default password is 'vodafone' in all lowercase. The username field is usually left blank or set to 'admin'. If you've changed the password and forgotten it, a factory reset will restore the default, though this will also wipe your custom Wi-Fi name and password. ### how long does it take to change Vodafone router to 2.4GHz The entire process takes about 5 minutes. You access the admin page at http://192.168.1.1/, log in, navigate to the Wi-Fi settings, and split the bands into separate SSIDs. No restart is usually required, though you may need to reconnect your devices to the new 2.4GHz network. ## Sources 1.
