Going to call WOW tomorrow and see about a modem swap, but just posting here to see if anyone's had the same issue...
I've been getting frequent speed drops on my 15/2 WOW service. I don't know how long it's been happening, since I only noticed when trying to play online on my Xbox 360 (I don't play online often). Every ~20 seconds, the game will drop to 1/0 bars and freeze for about 1-2 seconds, then resume normally.
I can see the drops when doing speedtests, took a pic here: »i.imgur.com/XcjYh.png
. Tried connecting my Xbox directly to the modem, brand new CAT-5 cable, tried a different coax cable to the wall, power cycled the modem, same problem. It's not a problem with the 360 either, I took it to a friend's and it was fine over there.
Something that may be related, I have an Arris TM402G/110 modem. We recently got rid of our WOW phone line, but the Telephone 1 light keeps blinking, even after resetting the modem. Shouldn't this be off/disabled? Thoughts?
