Should you need the configuration information from the previous saved configuration file, capture, copy or write down all required information from the configuration file loaded on the router BEFORE applying the newer firmware update. After the router has reset and come back to ready, reload the saved configuration file or reconfigure the router from scratch and walk thru the set up wizard.
Due to the large variety of router models and different methods for upgrading the device, it is highly recommended that you read and, above all, understand the installation steps before you apply the new firmware, even if you are a power user. Basically, you must upload the new firmware to the router through its administration page and allow it to upgrade. If you install a new version, you can expect increased security levels, different vulnerability issues to be resolved, improved overall performance and transfer speeds, enhanced compatibility with other devices, added support for newly developed technologies, as well as several other changes.
It is highly recommended to always use the most recent driver version available. Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver.
Problems can arise when your hardware device is too old or not supported any longer. Note: Some firmware upgrades reset the configuration options to the factory defaults.
To upgrade the firmware, your PC must have a wired connection to the router. Enter the name of the firmware upgrade file, and click on the Upload button. Firmware updates are released periodically to improve the functionality of your router and to add features. If you run into a problem with a specific feature of the router, check if updated firmware is available for your router. Fixes Apple Compatibility issue. Failure of the device may result. Use only hard-wired LAN network connections.
Save the current routers configuration to file. Note that reloading this onto new major version of firmware can cause problems and thus is recommended to configure the router from scratch.
Do not load the old configuration file from the old major version. If you're upgrading from minor to minor version, reloading of the configuration file shouldn't cause a problem.
In these cases, please do not upload the previous older configuration file, rather set up the router from scratch.
