Yes you can go ahead and click update on the router and allow it to upgrade to the latest for you.
Do this:
Quit the application/game/client completely
Remove device from the Geo-Filter
Give PC PlayStation Device Type in the Device Manager
Resync from the Geo-Filter Map menu
Re-add the device to the Geo-Filter
Set up the Geo-Filter how you like
Wait 2 minutes
Boot up application/game/client
You should be able to see the server/ping it on the Geo-Filter then. You may want to disable the filtering for the device if you have issues getting games and just use it to determine where you're playing and the connection quality.
How have you setup Congestion Control/SmartBOOST?
