It is also necessary to update your router's firmware.

Update your router's firmware

Newer versions of your router's firmware may contain a fix for this issue. Routers do not typically run updates automatically, so you need to manually download and install any available updates.

Consult the documentation for your router model for instructions on how to download and install firmware updates. If updated firmware is not available, contact the manufacturer of your router to request that they provide a firmware update as soon as possible.

If you are unable to install a firmware update, we recommend replacing your router.
