I would recommend comparing the internet speeds on the two OSes at a place like speedtest.net. This will help determine the internet speeds with actual metrics as opposed to how it feels. As for performance, linux should, if anything, be significantly faster than windows. There may be a few specific tasks in which windows may be more efficient, but I assume you would have mentioned if you were using wine or some other special case. As for the internet, perhaps the WPA2 login method has some additional steps that you haven't completed. You might want to talk to the network administrator about connecting, or if this is your wifi network, make sure you haven't forgotten anything.

You could try deactivating the IPV6 protocol if you're not using it. To do so, go in System settings > Network > Options > IPV6 settings and click on Ignore.

Otherwise, you could try using Namebench by following this tutorial.
