TP-Link WR841N - unreasonable disconnections?

Question

Computer networks

TP-Link WR841N has a designated device about 5 years old. It worked without complaints for more than one year, then rare random disconnections with the Internet via Wifi began to appear - when I went to the webmodra, I rebooted the device and everything went well. There were no problems with the wire.

Over the course of a couple of years, the breaks became more and more frequent, the webmord stopped loading, and it was possible to reach out only via Ethernet.
Recently, the cliffs began to occur once a day, and sometimes several times! 192.168.0.1 is no longer available at all, you have to reboot manually. The connection has become very unstable, constant freezes of a strange nature - when checking, both ping and speed are on top, but sometimes entire sites are not loaded.

I reflashed, updated the firmware, restored the backup and set it up again - nothing has changed.
The floating nature of the problem is especially confusing.
What could it be?

There are enough messages on the forums about similar problems, but no one finds an answer
Buying a new router just like that is no desire, although there is not enough usb port

Answer 1

I would first check for hardware problems: checking the parameters of electrolytic capacitors in the router itself and in its power supply. Since the device is not new, the electrolytes could dry out or swell and cause such failures. I would also check the stability of the voltage and current from the power supply.
Then we move on to software problems: I would solve them with openwrt firmware . Once I flashed it, set it up and forgot it for many years. No freezes, crashes, etc.

Answer 2

I join Konstantin ™ and d-sem - most likely, hardware problems, and most likely, the matter is in electrolytes. If you can open the network adapter and router with your own hands and replace the electrolytes - a soldering iron in your hands, and go! You can't - try replacing at least the network adapter with another one. You won’t find 9V - try 12V, I think the router from 12 Volts will not burn out. The main thing is not to confuse the polarity - "Plus" in the middle. And it will burn - and ... with it, it's still buggy, throw it away with a clear conscience.

Answer 3

I have been using TP-LINK TL-WR740N 150Mbps Wireless Router 802.11 b / g / n for several years. The same symptoms appear with wifi. On ehternet, the connection is normal until you connect via wifi and use it for a couple of minutes. Resetting to factory settings helped a little, but not for long. I will change

TP-Link is Chinese technology, the quality of the element base in it is mediocre, and sometimes used parts are used, plus firmware from TP-Link is extremely bad, they violate international RFC standards, most likely your router has a dead nand memory or swollen capacitors
