Porting Problem

I suddenly have an issue to where I get ported back about 20 feet to where I came from. It's hard to explain, but I'm basically running/riding or gathering something and suddenly I'm where I was - and when it happens during gathering it will say that I'm too far to collect.

I was recommended to delete some wod models and patch files, I did this with, but all no change. I then deleted and re-installed wrath with no addons and it did not work either.

In 15 years of WoW this hasn't happened to me before. I don't know that to do. I did buy a new monitor, but I don't know what the problem could be with that. I am now using a hdmi in my nvidia video card, instead of vga.

All help is appreciated.
Thank you.

I had same issue with my old internet, after i changed comppany problem went away. So might be your internet?

Oh good point! I'm using my landlord's wifi and it cuts out often. I will turn off the automatic connect option and see if it still happens or just dc's me. Thank you! :)
