So my Roku express no longer connects to my primary wifi. It sees the network, it just won't connect. Weird thing is I am able to connect to the wifi extender in the basement running on the same wifi. I'm on the second floor so connecting to the basement isn't the desired option. And yes, I'm sure the password is correct and I'm able to connect other devices to the primary network just fine. I've had the same network id and password for 4 years and just yesterday Roku just decided to stop connecting to it.
Try the Network Connection Reset: Settings/System/Advanced system settings/Network connection reset
Sometimes rebooting both the router and the Roku is necessary when experiencing a connection or wireless SSID handshake issue. Possible that the automatic router reboot after your firmware update resolved your issue and reestablished the connection.
Software (and its configuration/settings) is the key component in connectivity - and in connectivity problems. Its crucial to keep firmware/software/drivers as updated as possible for all networked devices, so make sure to check for updates from time to time (even for devices that auto-update).
Something to put in your bag of tricks should your Roku lose its network connection again in the future:
Here's what has worked for me to re-establish my net connection. I usually have to do this on my most used Roku, a Streaming Stick+, several times a month.
If that doesn't fix it, try disconnecting the power to your Roku for a few seconds. When it comes back up, see if you then can set up the network connection.
