Why the router can not work stably?

Good day,

Already a month has a problem and it is completely illogical and not understandable.

In General, there is router TP-LINK, worked perfectly, but as a month via LAN began to disappear, the network periodically 2-3 times per hour. And then began the same problem with wifi.

The router was about 2-3 years. Replaced TP-LINK archer c2. Absolutely the same problem, but only with wifi. Through 2 walls already does not catch. The rate cut is very strong. 1 wall at 80MB/s.

Thought the problem was in the channels and so on. But no.. I Found a very old dlink dir-320 and ... It works just perfectly, catches all gorgeous, Internet stable, 3 wall cut into 60 MB/s.

Put TP-LINK in repeater mode (WPS), so he also started to catch chic, but the Internet again has become unstable (like dlink 320 can not withstand the load) and start to fall even through LAN.

The situation is very strange, has anyone encountered such? Or similar? Which in theory could this be?

Scan for Wi-Fi for networking neighbors. To identify busy channels. To find a free channel. Switch to a free channel.
Already did, didn't help - maximo.Erns commented on March 12th 20 at 08:01
@maximo.Erns, Well then take a normal router. Keenetic or Mikrotik - isadore.Willms commented on March 12th 20 at 08:04
Oh, thanks, mikrotik. It would be extremely strange if even he would have problems. - maximo.Erns commented on March 12th 20 at 08:07

I had a similar situation on the ASUS router. Found out that overheats the chip inside the router, stuck it nope the radiator support. What that marriage must have been. But then switched to mikrotik. 5 years flight normal. Covered in dust but works wonderfully.
Thanks, looked at mikrotik. Awesome, already ordered. - maximo.Erns commented on March 12th 20 at 08:03

Do not forget to interference with household and industrial equipment used in adjacent rooms, which is often the cause of failures in the Wi-Fi networks
all of these factors affect the performance of Wi-Fi, often leading to unexpected situations, when you have a signal, and the network is practically not working.

spend radioablation ( there is a simple free program )

check the General settings
