Does the Aero have a web browser?
Yes. The Manhattan Aero has a simple web browser. Press and hold Home to open All Apps, then open the www app. Press up to bring up the on-screen keyboard, type a web address, then select Go.
You can use it to run a speed test on your connection: see Network troubleshooting steps.
The browser needs an internet connection to open, so it can’t be used to sign in to hotel or public Wi-Fi login pages. See Why won’t the Aero connect to hotel or public Wi-Fi? for how to get the Aero online in those places.
