32 or 64 bit advice

[firenice03]

I'd stick to the 64-bit as you wont have to go with Chromium...

Nevermind the updates - you're going to have failures on both "bits"
32 = Chrome needs removed
64 = Chrome needs updated

Thus far it looks like you're only in the live environment and haven't installed??

The wifi on the 3.19 kernel should work although "maybe buggy" from some of the posts I posted - where the newer kernel resolved..
Buggy could be, stability or drops... but 3.19 should get you installed and connected..

You are running on USB so it will be slower than when installed.

If everything is checking out for the most part and to your liking, you're probably good to go...
