I played WoW till a few months back, when my connection, for some reason, started giving me 5000+ ping (it can jump to crazy 21,000 in large raid instances like MC, BWL, etc). It wasn't an issue initially, then it started with me being unable to do BWL. Then it slowly got worse over a period of about a month, after which my connection became so terrible even normal playing was impossible (5000-7000 ping sucks big time

).
I was thinking of replaying, but I'm still worried about my connection. My friends told me to get a 215 or 218 IP, but my ZTE modem (the streamyx one) was set by my friend to auto-connect when I turn on my comp, forcing me to turn the modem on and off to reconnect. There may be a better way out there, but at the moment I'm not sure how. Restarting the modem is rather time consuming, and reconnecting like say, 10 times, can take almost one hour.
Any ideas how to help out with my problem? By the way I stay in SS18, if that is any help (maybe SS18 has connection problems or something, not sure....)
Thanks!
