I recently upgraded to fiber internet and now my Raspberry Pi won’t connect. I have tried legacy mode temporarily allowing 2.4 GHz and connecting my machine directly to the router which has not helped either. Any suggestions. I really dislike the USB shuffle to work with. ---

The ssid is case sensitive if I recall… Double check that it is exactly the same. Also if they replaced the router it may require deleting and re setting up the wifi connection in the controller. ---

We use a range extender that requires 2.4 and our network provider set up the modem so that it has both a 2.4 channel and a 5 gig channel. ---

Thank you for the help. The issue is that Raspberry Pi only runs on 2.4GHZ and my new internet is 5GHz. It is not the SSID or gig issue. ---

Hey Travis, I don’t know if this helps you but the [Raspberry Pi 3B](https://www.raspberrypi.com/products/raspberry-pi-3-model-b/) (not plus) inside the Onefinity Controller does not support 5 GHz. ---

Why not try a 2.4ghz adapter. This one supports a variety of Linux derivatives. BrosTrend AX300 WiFi 6 Linux Compatible WiFi Adapter, 2.4GHz Only, Nano Linux WiFi Adapter for PC, Raspberry Pi 2+, for Ubuntu, Mint, Debian, Kubuntu, Mate, Zorin, PureOS etc, USB WiFi Dongle 286Mbps [https://a.co/d/60W9FWV](https://a.co/d/60W9FWV) Amazon has a bunch of variations that have some serious external antennas in case you want to make sure you can hit it with your network wifi. ---

Provide a make/model on the fiber modem? if it doesn’t support 2.4G ??? I would be highly surprised if your I-net provider doesn’t have a model with both 2.4G and 5 ---

Took our modem into our local providers office and the nice man programmed the modem to have two channels the 2.4 one called (name) CNC and one called (name)5G ---

i ended up pulling a wired ethernet port to mine, the wifi is too crowded.
