While using the Netduma R1 I can not get into any games on Call of Duty. Whether I have the Geo-Filter on or off it will not work.
I have ensured the router is on the latest firmware update (v.3.0.207) and I have factory reset it multiple times.
Before making any changes to settings or adding devices the game will not allow me to connect to any lobby.
When the Geo-filter is running I can see potential servers.
Not sure what is going on, my only thought is maybe the R1 is just old hardware now and might struggle.
