Purchased one-time BOINGO wifi access at the Regan National Airport in Washington DC. First, it makes you download and install their software in order to connect to the internet. In the description they state it’s not necessary to do so, but HIGHLY encouraged. I tried using Boingo without installing their software – no luck. But $$ paid, so I give in and install it. Next, it kicks you our hourly – you have to re-login in every hour. I worked for 3hours and exactly after each hour it kicks you our. Which normally wouldn’t be an issue (even though it’s quite annouying), but I was using VPN connection to my work and every time they’d kick me out I had to go through a lot of troubles restoring VPN connection and re-logging everywhere… Bottom line – stay away, stick to T-mobile and AT&T wireless.
