Bad ping all the sudden?

So about 3 days ago i hop on wow to see my ping no longer says 32-38ms but now it says 80ms and acts as if its closer to 300ms…trace route and winmtr report show where the problem is and everyone can see it but no one can do anything about it. All the service reps beside blizzard just point fingers. Ive done everything their support articles have to offer about 4 times each now and i have freshly reinstalled windows even at this point the only thing i can do on my end is get a new router from my isp. Other than that im at a loss and continuing to play at 300ms-like ping is just something im willing to do =\ unsub may be imminent…hoping maybe someone has an idea? Also tried tunnel bear. Nothing.

were are you located?

Going to be closing this thread. Based on your ISP, the issue is likely going to be related to the Spectrum post here.
