Sometimes I type nytimes.com and my browser takes me to usatoday.com. Sometimes google.com takes me to Bing.com. Sometimes I enter online.wsj.com (Wall street Journal), but I'm taken to online.wsj.com/dr, a sub-directory that doesn't exist, and fails to display any web page.
The problem occurs sporadically and lasts a few minutes before things become normal. I have both Windows and Linux installed, but both display this problem. Very curiously, I never have this problem when I use my laptops at other places. However, when I use it at home (with Wifi) I have this strange problem.
I've checked for virus like DnsChanger, but haven't found anything. I suspect either my ISP is doing something strange, or the Wifi router at home is flawed. What do you think?
