I'm on a home wireless network on my Laptop running Windows 8.1. There are 2 wireless networks in the house for coverage reasons and I swap between the two fairly regularly.
The issues is my DNS queries intermittently fail. e.g. Browsing internet and get "DNS probe failed". This is unrelated to changing wireless networks, e.g. I may not move the laptop all day and still experience the problem.
I run "ipconfig /flushdns" and it fixes the problem for a while, though I'm a bit sick of having to do it multiple times throughout the day and it usually fails when I don't want it to like when I want to post a comment here!
So I'm wondering if someone can shed some light on it or help me with the troubleshooting steps.
I have tested this and get similar issues on my tablet, ipad and phone. I'm not sure, but I did test all day yesterday being directly connected with a network cable and can't remember getting the issue but I don't want to assume just yet that it's the wireless.
Happy to provide more info as needed.
