How to reboot WAG54G2 from Web Management
You can do the backup/restore trick:
Go to the Backup & Restore page under Administration:
Backup your configuration.
Restore with the backup you just saved.
This makes your router restart but changes nothing in the configuration!
you're out of luck, no restart from the HTML interface of the WAG54G2.
power off/on is the only way.
