I've found that I can only get to the configuration page of my router if I close Ad-Muncher. Simply disabling the filtering doesn't help.
I've tried this in IE8, IE9, Chrome and Firefox. All of them display the login page correctly. If you enter the wrong details they all display the correct error message. If you enter details correctly they all 'stall' after changing the title bar from 'Thompson Gateway - Login' to 'Thompson Gateway - Home'. IE8 also clears the browser window but the others just sit there showing the spinner.
If filtering is active the log shows the following:
Aborted filtering of connection due to unrecognised content encoding [http://192.168.1.254/util.js]

Any thoughts?
