I'm sorry but I may not have been clear: I already tried splitting the SSID so that only 2.4GHz was valid. I also made sure that the channel was valid (was on 11).
Neither of these solutions worked...
The channels 1, 6 and 11 are the best choices on 2.4GHz. But since you aren't even seeing the SSID when you're on channel 6 or 11, I suspect a hardware failure of some type. If your network is working correctly with other devices, most likely there's an issue with the Roku itself. The Roku Express has an internal WiFi antenna, so it's not anything that could be damaged from handling.
The 3930 is approaching 5 years old now, and while that is certainly well within an expected lifetime, it may have simply failed. Unfortunately that can happen with electronic devices at any age. I'm not a fan of the basic Express for multiple reasons, but lack of 5 GHz WiFi is a big one for me. If the Express 4K+ is available in Europe, I strongly suggest it as a replacement. There's no comparison between one of those and the model you have.
