Thank you so much @Netduma Fraser for your help here and in every forum. it's the best customer support i have ever seen. But honestly, I was so excited after seeing the features but i got disappointed.
And Yes. This is what i did. i followed your instructions. And seems after any changes of these I've to Hard reset the router and re-do everything again. I became a setup expert 😂.
it seems unstable with different readings of speed (Using speed test . net ) and still can't ping any server, so i will be back to my XR500. The only reason i upgraded because i wanted to have the Steady Ping feature, which does much (Yet) with random numbers being added. And sadly, i can't see it in action since i still can't see how's the ping performance is during the gameplay.
Not sure what i should do next.. Tired of hard reset.
