Who knows what the problem may be? Or are there ways to find her?

Change the wi-fi channel of the router and the width of the stream

In theory, yes ...
The purpose of the firmware update or change the official to third-party?
The firmware process is simple, first the firmware file is uploaded to the router, and only then the router is flashing itself.

I want to update: rolleyes: Since the purchase, it has not been updated since May 2013. And if you replace the antenna from 5dBi to 8dBi the signal quality will improve? or just a radius?

Special arrival should not wait when replacing the antenna.
And the firmware is better to change to third-party.

I used WR741ND v4 for about 10 months without the slightest criticism of it ... but nothing lasts forever. About two weeks ago, the beginning of persistently disappearing the Internet connection via WiFi channel while the PC connected via the LAN quietly sees the Internet. WiFi is only connected to the lenovo s650 smartphone (at first it was all about it).
WiFi can simply be disconnected for a while that my network is not visible, there may be no internet when the network is visible and it is impossible to enter the router menu from the phone. Turning the WiFi on / off on the phone either leads to the fact that the router is invisible, the router is visible, but it does not receive ip from it, well, for a change, there is a connection. At the same time, the phone easily connects to a barely glowing signal (-90 bd), sometimes visible open network. Besides, he noticed that the signal power from the router became less and the connection even near the router rarely exceeds 11 mbps.
The manual registration of the ip of the phone, gateway and dns in the phone partially helped against the Internet dump, but it became less likely to disconnect the router’s signal strength.
The router has the latest Russian official firmware, dhcp is configured to issue three ip by Macs, the WiFi connection class is the author, the width of the channels is also static channel (changing channels did not affect the problem).
If koto knows how to solve such a problem or write down its reason, I will be very grateful.

* Boyarinc,
Try to replace the power supply of the router, as well as disassemble the router and see if there are any swollen capacitors on the PCB.

Good day to all!!! Sori for offtopic! But I rummaged through the Internet (maybe I dug badly of course))) and I can’t solve my problem, I have a tp-link wr741nd device, my wan port has been burned, changed to openwrt, I assigned a port, I set it up, but I can't bring it to mind if the PC is connected to the router via a cable, I cannot connect to the router on the tablet, the phone, if you connect via wi-fi first and then turn on the PC, then the PC remains without the Internet, the router does not want to work on more than one consumer, if Who faced - I ask for help! What am I doing wrong? Thank you in advance!!!

Difficult to say remotely.
Lay out at least logs for clarity and a link to the instructions on which the port reassigned.

If anyone came across - I ask for help! What am I doing wrong? Thank you in advance!!!
Most likely the plug is here / etc / config / network
And just do it, countryman, the network is full of information. Some native TP-Link firmware have the function of a bridge between the LAN and WAN with the help of it can be solved.
On openwrt seehereandhere
By the wayHEREThe person solved the problem on the native TL-WR741ND firmware.
ButHEREDescribes the option of obtaining the Internet through the LAN ports on the OpenWRT firmware TP-Link TL-WR741ND through commands.

Thanks for the advice, but unfortunately the change of power supply did not help, the problem remained, but didn’t disassemble it because the warranty period had not expired.
But the decision is still found: I stitched a third-party firmwareDD-WRT 04-18-2014-r23919and now 2 days no WiFi connection failure between the router and the smartphone.
Initially, I installed the latest version 12-22-2014-r25697, but it blocked ping between LAN ports, and it was impossible to use a cable connection between a PC and a TV.
P.S. Oh, there are not enough messages on the forum to put a plus sign.

* Boyarinc,
It is necessary to look at the settings, it does not block anything.

* -SunLion-,
I read several pages on various forums dedicated to this topic - they say everywhere that in DD-WRT 05-23-2014-r24118 there is an error in the operation of LAN ports, they do not see each other in general, but in the direction of WiFi-LAN everything is in order, IP respond without problems. Apparently, this error passed to all subsequent versions of DD-WRT, or at least the last two versions of 2014, which I first tried.
Of course I would like to deliver the latest version but I did not find a solution to the problem.
However, I didn’t notice the difference between the latest versions of DD-WRT and 04-18-2014-r23919, except for the working LANs and a slightly different translation, the load on the router's processor, the quality of WiFi and the packet delay is the same.

PutDD-WRT 02-04-2015-r26138On your WR741ND V4.22, the problem immediately arose again, the LANs do not see each other ... you can see that the programmer did not take into account something in the scripts.
After a brief search on the DD-WRT forum, I found a solution. The problem was that there was no VLAn between LAN 1-4.

Global attributes:
enable_vlan: 0


solution (can someone come in handy so as not to look for yourself):
In the menu of the router: Administration / Commands
enter the code:

swconfig dev eth1 set enable_vlan 1
swconfig dev eth1 set apply


(eth1 - LAN interface)

Click Save Startup Parameters and reload the router.
After restarting there is ping between LAN ports, packets are passing))

* Boyarinc,
As an option, you can go to the hidden web page of the router settings interface
192.168.1.1/Vlan.asp
and do the same through a graphical interface.
(192.168.1.1 - address of the router)

I went to /Vlan.asp, even before the console commands nashol, only it is not clear how to configure.
LAN 1-4 ports are ticked in VLAN 0, the destination over the bridge is NO. Earlier, I changed my assignment on - LAN, so nothing came of it.

Greetings.

How on this router to prohibit by poppy address or ip (with ip connection by poppy) to connect the computer to the network? Suppose there is filtering in the wifa, and if the villain has a wire stuck in the lan port? How to be?

Well, if someone has physical access to the router ...
As an option - limit the number of ip addresses issued by the router and bind each to a specific device by MAC.
