Roku Express not connecting to wifi November 2023
Recently I changed my internet service provider and had high speed fibre optic internet installed (called Telus PureFibre; I'm located in Alberta, Canada). I have no idea if it is 5 or 2.5 GHz or neither or both (?).
My Roku Express worked perfectly for about a month after the switch, then one night, mid-program it stopped connecting to wifi. Since then, despite a LOT of troubleshooting, I'm still without my beloved Roku. Note, it's definitely a Roku thing, all my other devices with wifi connections have no issues.
The other postings I've read here are similar but most quite dated, and resulted in the person being contacted directly. So please, any assistance Roku can provide will be most appreciated. I'd really like to resolve this.
Kind thanks,

Some further things to look into and try...
1. When you made the password change, are you sure you made it to the SSID under the 2.4ghz band? (The Express 3930 cannot see/use the 5ghz band, so making any changes under the 5ghz settings won't help your issue. Need to make sure you are changing/editing the 2.4ghz settings.
Also, make sure to restart both the modem/router and your Roku device after making changes to modem/router settings.
2. Try leaving the password field under the 2.4 ghz SSID empty (creates an open network). See if Roku connects.
3. If still getting 14.40 error with both the changed password and the empty password/open network, perform a Network Connection Reset on the Roku device. (Settings/System/Advanced System Settings/Network Connection Reset/Reset Connection). Then try both #1 and #2 again.
4. Under the Wireless Security Settings for the 2.4ghz band, try looking for something that says WPA2 or AES/PSK. Verify that WPA2 is set and not WPA3. If WPA3 is available, initially change it to WPA2 and then check to see if Roku can connect. If successful, then can be changed to WPA2/WPA3 and see if still able to connect. If set to WPA3-only, Roku devices will not connect. (not sure what kind of router you have, but Telus seems to provide Wifi6 routers so WPA3 likely in use on them).
5. As renojim also indicated, look for your Wireless Mode/Protocol under the 2.4ghz settings and verify that set to a default b/g/n. (this will allow all speed protocols to be used and rule out this known culprit on some cable ISP networks. Reportedly will throw both 14.30 and 14.40 errors).
6. If all the above fail to get you past the 14.40 error and connected, try connecting to a mobile hotspot if available. If you can connect to the hotspot, then your Express 3930 hardware is working and there is a compatibility issue between your new Telus router/setup and the Roku device. (ie. likely conflict in one of the firmwares of either the router or the Roku device handling authentication).
