Late last year new Linksys routers started having severe DNS issues that would cause a computer to redirect to random websites without any control of the user. It most often seems to happen with Facebook redirecting to MySpace, but other sites do the same and lead to often scary websites from different countries. You have no idea what site you could end up on! This could be a security issue, not to mention very frustrating because it can be days, and hours of tinkering, before you're able to finally access a site without being redirected.
Anyway, my parents have a Linksys router, and are among the many who have this problem. I've tried my best to help them out, since they aren't exactly computer literate. I wouldn't call myself an expert either, but I at least do research to learn more about the problem. My mother says it's probably because their new Mac is 4G capable, yet they have 3G internet. Though I can see that causing potential problems, I know that's not what's making YouTube redirect to Yahoo, or Facebook redirecting to MySpace virtually every time they try to get on it. They've been having the issue for months, and it's getting worse. So now I'm turning to you guys for help.
I've found many solutions online, and many sound to be very good from what people have said. The best suggestion I could find was at http://homecommunity.cisco.com/t5/Wireless-Routers/WRT160N-V3-has-serioius-DNS-issues/m-p/295284#M154543
But they're all for Windows PCs, not Macs. So my basic question is-
How do I do this on a Mac?
I'm much more knowledgeable about PCs, so I'm lost when trying to search the system for a way to do this. I'm sure any info will be of help to anyone else who is having this issue and searching for a fix. So thank you in advance for any help you can offer.
