After booting an Ubuntu 14.04 Live from USB I connect to the internet everything works great for a few seconds, then the internet stops working. It doesn't say it's disconnected or anything like that, but webpages won't load,
sudo apt-get update can't connect.
My internet access is fine, I am able to stream music on my tablet while using the Live USB. The installed OS on my laptop is Windows 10 and I have no problem accessing the internet from there.
I tried this with both Live Ubuntu and Linux Mint ISO images loaded from an USB stick.
For the initial couple seconds that the internet works after connecting to my WiFi, pages load quickly. If I connect to a second network, it works again for a few seconds, but then stops as before.
EDIT: I've tried pinging my router's IP from the command line immediately after connecting, and the packages are received as expected for a short while, but then suddenly stop.
