I plugged the device in wired, and that didn't help. Here is the text from the page I see:
Meteobridge Landing Page (FW 1.1)
You got here, because Meteobridge application stack you wanted to access could not be loaded from the Internet. Most common reason for that is a bad network configuration of the Meteobridge device, that keeps the unit in endless fast blinking LED mode. From here you can do one of the following:
Wait: May be Meteobridge is still in the process of loading application stack from the Internet and it just needs a bit more time. You can give it a second try by this link
Cloud Simulator: You can setup a new network configuration for your device via this configurator in the cloud. You find details how to use this servive in the Meteobridge wiki, here.
Back to Defaults: When you have your Meteobridge in a cabled LAN environent with a DHCP server (mostly the router) up and running, you might be able to solve your networking issue by bringing your device back to standard network setup, by pressing the button until LED lights up for the first time. Unit will reboot in standard LAN DHCP client mode.
OpenWrt: As OpenWrt is fully operational in your device's flash storage and does not need to load an application stack from the Internet, you can start OpenWrt operation by this link. As OpenWrt is a very complex router setup, this is only recommended for experts, who are familar with OpenWrt and might be able to solve networking issues on that level.
To give you insight what your current networking setup is, you'll find some more networking details below. If you are not that deep into networking, just ignore.
