In various cases, your Tp-link router doesn’t respond during the Firmware Update process. The common reason is that your router may have loose power during the installation of the firmware. If due to any reason the update process gets corrupted, the firmware update process gets failed. During the failure of an update process, a user can utilize the Firmware recovery option that the Tp-link router provides to avoid the hassle to again perform the update process through the tplinkwifi.net window. If your router doesn’t support the Firmware recovery function, you can contact the Technical support team to help you out in that situation.
