Reconnect
Reconnect is my second Safari Extension. It provides a tool bar button to make your router drop your internet connection and reconnect again. A tool tip shows the current external IP address.
After installing this extension it has to be configured before it works: You have to set the IP address of your router in the Settings panel of this extension (unless you own a Fritz!Box by AVM).
This should work with any router that supports UPnP. Please tell me if it doesn’t work with your router.
