Idézet a firmware-hez tartozó leírásból:
There are two ways to upgrade your router, but before you upgrade it there is something you should know.
1)Write down all the current settings as you have to enter them manually after upgrade.
2)Choose the firmware which has the same hardware version as yours.
3)Do NOT upgrade firmware from a computer with a wireless connection. Use a computer that you can connect to the router with an Ethernet cable. You may damage the router due to the increased packet loss with a wireless connection.
4)Do NOT turn off the power during upgrading.
