Update software or firmware may be needed in several cases. For example, you are configuring new router, therefore, before setting it up, it makes sense to look at the manufacturer's official website and if there is a software version there that is newer than the one you have installed, then it is recommended to install it. This will reduce the likelihood of any problems in the further operation of the device, because the manufacturer is constantly improving programs for its equipment, taking into account the errors and shortcomings of previous versions.
From time to time, you should update the firmware of the device in order to avoid problems in its operation.
And if your TP-LINK TL-WR740N router is already configured and working, but you observe periodic disconnections with the provider, loss of wireless network or other failures, then one of the solutions to the problem is to flash the device again.
The order of the firmware
To update the firmware on the TP-LINK TL-WR740N router, follow these steps:
- Look at the sticker for the hardware version of your device - this is important for selecting the correct firmware version.
- Go to the official website of the manufacturer, in the "Downloads" section, find the model of your router and the latest version of the available software for it. The latest version will be the first on the list of available downloads.
- Download the firmware file, save it to your hard disk.
- Connect the router with one of the LAN ports to the computer's network card.
- Go to the web interface of the router at 192.168.0.1.
- Go to the "System Tools" section, then to the "Firmware Update" tab.
- Use the "Browse" button to find the folder where the firmware is saved.
- Click "Update".
Important points when updating software
If you need to flash tP-LINK router TL-WR740N, then remember some precautions associated with this process:
- The software update is performed only via a wired connection and only via the LAN port. Do not use Wi-Fi for this, as the wireless network may have a momentary interruption that will unpredictably affect the firmware installation.
- It is also recommended to disconnect from it all other devices: wired and wireless.
- While the update is in progress, do not turn off the router, do not restart it or reset the settings. Be sure to wait until the end of the process - it usually takes no more than 5 minutes. After the update is complete, the device will reboot and again request authorization on the web interface.
- If your TP-LINK TL-WR740N has already been configured, then after the firmware the configuration will have to be done again.
Consider the general scheme tp-Link connections WR740N / Tp-Link WR741ND, as you noticed in this article, we will consider setting up two routers at once, since they differ from each other only in antennas (the 741ND has a removable antenna, and the 740N has a non-removable antenna).
As you can see, everything is quite simple, connect the router to a 220 V power supply, then connect the computer / laptop with the supplied network cable, insert the provider's cable into the WAN port, to turn on it remains to press the Power button.

And all this despite the fact that the configuration of the custom router model is described. The interface difference is the most easily noticeable a sign of a different firmware, but far from the most important.
Router firmware its firmware is called, which is responsible for the interaction of all hardware components, as well as for transmitting, receiving and processing data. Often, devices are released with raw firmware, and errors occur during their operation. Developers receive bug reports as well as user comments and fix issues and optimize performance. When there are many such fixes, then a new version software for the router. Some of them can download and update software themselves, but not all. This article will describe how to flash TP-Link TL-WR740N.
Where to find and how to download the firmware

Otherwise, a breakdown will occur, and it will not be possible to restore the device to work on its own. It should also be borne in mind that the firmware is installed only for specific model router.
Video instructions for updating the firmware
Currently, the situation is such that quality software is not always completed simultaneously with the release of the device. And manufacturers have to release firmware updates after the router goes to market. Improving at the same time bugs and shortcomings suddenly discovered by users.
Any router is supplied by softwarethat perform the operations of transporting encryption, data, transmission, sending packets, creating, connecting, and so on. Standards have an unpleasant tendency to be reworked and a router with old firmware may not work in new standards. Do not throw away a properly functioning device just because it is incompatible with the latest software standards?
IN similar cases rescues flashing the TL-WR740N router, which is nothing more than replacing the old router software with fresh ones. But, unlike updating a simple program, updating the firmware carries a certain amount of risk and can, sometimes, lead to an absolute loss of the router's performance. In order to avoid such a misunderstanding, follow the tips on this page before and during flashing of the TP-Link TL-WR740N router to reduce the likelihood of device failure to nothing.
How to update the firmware of TL-WR740N router?
Therefore, before flashing, ensure the computer that boots from new firmware for a TL-WR740N router with an uninterruptible power supply, for example, by connecting to a device like UPS. No one is insured against a power outage, and if the power is turned off during a microcode update, there is a 95% chance that the TP-Link TL-WR740N router will have to be carefully packed in a box and taken to the service.
Before starting the flashing, pull out all the connecting cords from the router, leaving only the cable from the PC through which the firmware will be done. It is very undesirable that signals for signal transmission are sent to the router at the update stage. Not all routers properly respond to such packets during the flashing process. To prevent this from happening, update by booting into safe mode mode with network support. Thus, you will know that no program will go online for an update or for any other reason.
Reset the router settings, as a rule, this can be done by pressing the "Reset" button located at the back of the router case. The fact is that after flashing the software, in 50% of cases, the router has to be configured first in order to avoid incompatibility with the configuration file made by old firmware versions.
