Hello, I was noticing increased ping & packet loss (lag spurts) while playing world of warcraft (only online game I play atm) & started searching for an answer. I had just upgraded my optimum online package to get Voip & the tech had replaced my old Motorolla surfboard (no voip port) with the SB5120. I did not play WoW for a couple days after I got the new SB5120 & figured the lag was something game/server related. After talking to a friend in the area who also has optimum online & plays on the same server as me, was not experiencing these problems I than started to think what it could be & only thing that has changed on my network/cpu is the SB5120. After doing some searching I found a post "I would go with the SB5100 because the SB5120 gives high pings, packet loss, and if you play on line games it gives you lag. Smile " & wanted to ask what others experience with the SB5120 was. I tried finding other users/ forum post with similar issues but had no luck. Thanks for your time/help in attempt to return to normal gaming
