I just got fiber optic internet and now my Roku Express won't recognize the network login. I am sure the password is correct. My smart TV is connected just fine. My internet service provider says that Roku must update the VLAN tagging 201 under the WAN. My limited experience with that says AN is area network, W is wide but from there I am lost. Furthermore there is a black hole when trying to contact Roku about this. Can anyone help me?
I believe CenturyLink uses VLAN id 201. This is normally handled by the CenturyLink router (it communicates with the fiber ONT). If you are using your own router (or your own switch), you will need to verify that your router supports "IP tagging/IP Internet Tagging" These settings are normally under Advanced Settings or LAN settings. This is where you set the port for IP Tagging to 201.
At first glance, kind of doubt this is your issue though since this should have been performed when you received your fiber and setup by your ISP. These issues with tagging normally arise when people swap out their routers or network equipment for their own preferred devices or have an issue with their service.
I think the first thing I would look at is to verify the 2.4ghz band is enabled and working. Then try changing your password to a new simple password for testing. (No special characters, just numbers or letters). Then restart both the router and Roku and see if you can connect.
