guids and n.s. are giving good advice.

I will add to what n.s. said though. Your bank, brokerage firm, reputable e-commerce sites, Gmail, etc, are all using encryption (you'll see a padlock in your browser) when you are handing off a password to them.

However many other sites where you use a password, including 2+2, are not encrypted when you hand off the password.

Therefore if you use the same password everywhere then wireless might be very dangerous for you.

I suggest not using the same password everywhere, and certainly not using the same password for unencrypted sites that you use for encrypted sites with information you really want to protect.
