Hey guys hoping there is a network tech savvy person to help me , so yesterday I decited to buy my own modem instead of paying extra monthly to the isp , I did my research and decided to go with the arris SB6190 , so I called the isp they got its mac blah blah and it was connected.
I test every website , everything internet connection related and everything works fine Except Connecting to the e+ servers, now before this I had my router setup is been on for about a year is a Netgear Nighthawk X4 R7500v2 , Again before this modem everything was fine so I figured it has nothing to do with the router.

So I called the isp and they just rebooted the modem from their end , and I rebooted the pc and it seemed to work , play a few games then I take a break a few hours later I try to go in again and again is not connecting , the weird thing is from qconnect when is not gonna work it tends to now show all the servers , but it does show mostly all of them but when I connect it stays on awaiting challenge.

So I figured well maybe there is some compatibility issue with the router , and I tried with the modem alone , same thing , now on this modem there is no settings to port forward anything , so again I gave it another shot and I port forward on the router , and it worked , I didn't restart my oc or anything I just set up port forward on the router from 27920-27999 and it worked , that was yesterday I play a few games on beer . Oh and I know is gonna work because when I have tried to test this settings and somehow sometimes it works the qconnect software loads all the servers normally like it did before this new modem .

Now this morning I try to play again so I run my qconnect and same shit again , partial servers show up I try to connect to any of them and awaiting connection stays on forever without connecting .... . WTFFFFF

Any help would be great , some1? thanks 1
