How to view the logs of the tp link tl-wr740n router if you forgot your username and password?

Question

Iron

Hello. Subject: TL-WR740N 192.168.0.2
In short, the router is not mine.
But I installed the latest firmware for 2016 (I don’t remember what problems there were)
Hardware version 4.2
The network scheme is as follows: the provider gives ethernet> The one is connected to the router without wifi (dhcp server)> Lantolan is connected with a cable (dhcp off, plays the role of a wifi antenna or whatever it is) to our router, wireless devices are already connected to it.
Complained that it falls off several times a day.
You need to go to see the logs, but the login and password have long been forgotten.
There is no time to do a reset and reconfigure, then waiting until it starts to fall off is also not an option. He can work half a day. It can fall off 3 times in 2 hours. Internet speed in / out 3Mbit / sec (900 rubles, where is it more?)
What's the matter: 1 devices are connected, but there is no Internet, win 10 diagnostics indicate that there is no access to dns. Although it is (Google is always available). Infa 100k. On the wire, all the rules (receivers, tvboxes)
2 point disappears from the list of networks nafig, restarting saves. On the wire again - all the rules. With a wired network, there are no problems at all, on devices, too, Google dns, as in router 1
Firewall, all sorts of protection algorithms are all disabled on our friend. WiFi 802.11n wpa2. Well, maybe someone needs the characteristics, here.
Not enough devices connected at the same time. Max by air 2 laptops 2 bodies at the same time.
Now the question is: how to enter? There are backdoors, master passwords, brute (but there is protection), mb somehow you can see the logs in ridonly mode.
And another topic for thought: mb is it heating up? The power supply seems to be a little warm. But I read about the fact that they row, so they fall off. That's just why it should, if its protection is disabled (everything is enabled in router 1), computers do not spam into the channel (that is, there are no viruses), there is nothing to transmit via LAN.
Or mb firmware is so stupid? Let's think together
. Sorry for the mnogabukaf, but just so that there are fewer questions (ask if anything)

Neither one nor the other I
checked the percentage for a finger, a little warm
Well, okay, I still found the time and did a reset

4th day, so far without relapses
Upd: Installed DD-WRT, t .k in stock over time starts to hang again over time. Now it works like clockwork
