Difference DD-WRT firmware from factory
First, it is worth noting that DD-WRT firmware is an operating system based on the Linux kernel. Even with the default settings it has a very wide functionality, much wider than in the factory firmware. Built-in components such as FTP server, Samba, WOL and more. Through the Web interface, detailed statistics and load on the channels of the local, wireless network and the Internet are available, as well as the load on the processor and the memory of the router.

If you configure the router to install additional packages, you can turn your router into a home media server. A connected hard drive with a torrent client installed, broadcasting ITPV via HTTP, for viewing via wi-fi. If you have a TV with DLNA standard support, you can connect the TV to the router and watch IPTV, as well as watch movies from your hard drive.

How to flash (install) DD-WRT

factory-to-ddwrt.bin - file for installing DD-WRT from under the router's native firmware.

webflash.bin - file for updating from already installed DD-WRT.

For some models, only one file is available for all operations.

Forthe originalDD-WRT installations:

In the address bar of the browser we typehttp://192.168.1.1orhttp://192.168.0.1,depends on the router, enter the data for authorization and update the filefactory-to-ddwrt.bin through the standard update menu in your router.
After some time, the router will reboot, after which you will see the updated interface (DD-WRT's address is 192.168.1.1 by default). On the main page when you first start you need to specify the username and password for administration.
Firmware dd-wrt installed, you can proceed to configure. (It is also recommended to do a reset to the factory settings after the firmware and before the setting)

If you have any problems in the impossibility of entering the DD-WRT admin panel after the firmware, go to network connections on your computer and make sure that the IP addresses are issued correctly: IP: 192.168.1.xxx (the last digit may vary) Mask: 255.255.255.0 Gateway: 192.168.1.1. If addresses are different, then the easiest option to restart the network card (on and off. Then the network will again request the addresses by DHCP), if it does not help, enter manually, for example IP 192.168.1.2, mask: 255.255.255.0 Gateway: 192.168. 1.1 and try again to enter the browser at 192.168.1.1.
Going to the web interface of the router, the tab "Settings" - "Basic Settings" - find this item:
Attached Image
Must be "DHCP server", if not, put.
The fact is that if there is a "redirection" your router will redirect the provider's IP address to your computer, that is, it will work as a switch.

ForupdatesDD-WRT already installed:

In the DD-WRT menu, select “Administration” - in the submenu, select the “Firmware upgrade” item. Click on the button “select file” and specify the firmwarewebflash.bin which was downloaded earlier. Click on the “Upgrade” button, the software update process will begin.

Options for rolling back to stock (native) firmware
Important!If you do not know how to return the stock on your router or do it for the first time, before performing any operations with the router, it is better to ask in this topic or topic visited by your router.Not all methods are universal., each router needs its own approach.
FAQ

AT: How to properly flash the router?
ABOUT:
  • Do not flash the router via WiFi; connect it to your computer with a network cable;
  • Before and after the firmware, make a hardware reset of the router (for example, "30/30/30");
  • Disable firewalls, antiviruses and ad blockers on your computer;
AT: What is "Reset 30/30/30"?
ABOUT: Press the reset button and hold it. After 30 seconds, turn off the power without releasing the Reset button. After another 30 seconds, release the Reset, turn on the power, wait until any other light on the router lights up except for the power supply, or the PC does not see the router, again we hold the Reset. Wait another 30 seconds and release the reset.

AT: How to view the system log?
ABOUT: You must first enable the syslogd service in the Services tab. (The field with the server name can be left blank.) And follow the link http://192.168.1.1/Syslog.asp, The page can be accessed only through the address bar.
If you don’t open the System Log page, then you have an old firmware version, and the log messages are written to the file / var / log / messages, which can be viewed with the commands cat, tail, more, less, etc.

AT: How to connect telnet to the router with DD-WRT?
ABOUT: Open a session in telnet client with the address of the router (by default 192.168.1.1) and the standard port (23). When prompted for a username (login), enter the standard root name - even if you changed the username to log in to the web interface. And when prompted for a password, enter the password you set for the web interface.

AT: How to load into the router not one script, but two?
ABOUT: Put the & sign at the end of the first script and load the second one. If you later need to load the third one, put the & sign at the end of the second script, etc.

AT: The Russian language does not work. Why?
ABOUT: Most likely the problem is in the firmware, the Russian works again in all releases of 2016. Also in the old stable versions.

Q: "retracker.local" stopped working, what to do?
ABOUT: It is necessary to turn off "No DNS Rebind" in the section "Services" - "Services" - "DNSMasq".

Q: Can I enable HTTPS?
ABOUT: You can, but to use it you need a special browser. Also, if you uncheck HTTP and leave only HTTPS, then you will most likely have to do a reset, since you will not access the Web GUI through a regular browser. (If you uncheck both checkboxes, you won’t go to the web interface at all)

Q: Does Universal Plug and Play (UPnP) work?
ABOUT: Yes, but you need to enable it manually, in the section "NAT / QoS" - "UPnP"

Q: I climbed in the settings and now I have a low rate of return or reception, why?
ABOUT: Most likely you have enabled "QoS", check if it is, then disable it.

Q: I set the TX Power to 20, but shows 16 dBm, why? I know for sure that the router can work on this power!
ABOUT: Perhaps the power is limited, because of the region you selected in the WiFi settings.Change to another, for example "US".

Q: TX Power has set 20 (or 21), the region is needed, but the router shows 19 dBm, why?
ABOUT: Maximum power can be obtained only on channel 6.

The first one that WAN. Just enter the old there, click Apply, you may need to restart the router.
P.S. Something tells me that you have on your native firmware, i.e. The poppy, and DD-WRT after installing it on the router, respectively, returned the native poppy router :) And maybe I am mistaken, it's just reflections.

Something tells me what will happen as well as with the last one.

Based on file extensions in this instruction * .ko, it seems just lacking some kind of kernel modules for the modem operation, so it is not defined.

Good day to you. Such a question: stands at home Dir-300 from the DD-VD. I want to make a white list in Maku, but in the settings found a Mac filter on Wi-Fay. How to make a list of the white list of addresses for 2 connections (Wi-Fi and Wire) in one. Found in 2 places a restriction: Vi-Fig-Mac filter and access restriction. In Vi-Fi, everything is normally blocking, a poppy blocking does not occur in the access restriction. I'm more concerned about the lock on the cable than on Vi-Fi



Rep: (579)
Console and MTD Firmware
Brief about how it is done
Login by SSH or Telnet.
Go to a temporary folder
cd / tmp /

Swing VGU firmware
Wget http: // file address.bin
(The Internet must be configured on the router, so that it can download the firmware and the server from which the download should work on the usual HTTP, not on HTTPS, for example from under Linux it is very convenient to use the QWeborf program, simply by pointing it a catalog where the firmware is lying)
You can still throw a file via SFTP or SCP (Google WinSCP if that)
Well, stitched
MTD Write file name.bin Linux
(orMtD Write File Name.Bin Firmware If the first option does not roll)
at the end
reboot

is ready.
It should look like this

Attention!Here, too, there are nuances, in the case of returning to your native firmware, this method may need a firmware file without a BOOT block, so it is better to read about a specific model before performing data of manipulations.
There are files without boot for TP-LINK
If at the end you are issuedErasing mtd failed: linux Then do not reboot your router otherwise it will no longer boot, as there will be nothing to ship
In this case, it will help the fill with the same method of the initial Factory-to-DDWRT file (what has already stood) and it is advisable not to pull with it, otherwise the router can simply hang, and after rebooting we already know what happens. So before the firmware operation is also recommended to download the DD-WRT firmware files for your model, which you have already been installed.

And what is the way the method connects to the selected point, the client and client-bridge? Router Tplink 841 (8) connects to the point as a regular client and distributes no wafer. And Tplink 740 (4) (with the same version of the firmware, as well as on 841, old stable for 2015.) Does not want to connect as a client (in the sense is connected, the fio distributes, but there is no Internet itself, only if I choose the connection method as client-bridge?

Client Bridge

Client Mode
As I understood the essence of the same and the same, but in the Client mode you can pick up WiFi as WAN, and in the Client BridgeD (Routed) mode, the WAN port is not at all, and it turns out something like WiFi Sweat. That's how it seems like.

ATP for the expansion. Topics, in a nutshell, a client, better than Clertebridge. I can subnet to change on my own, and not to adapt, under the primariroter. But questions, we still remain, why the same version of the prosta, so differently behaves Different routers? A.V. These different connections, I am all the same on my routers (both secondary), leave HCDP automatic (for some reason, only so, there is a distribution of Neta). And here is the moment! One router (841) is connected to a point with IP 192.168.1.1, in the client mode, the output is registered IP 192.168.10.22 (so as not to be confused what is two-haired), the second router (740), managed to connect to another FAY, only in customer mode, but! So that there is a network type, 192.168.10.x (Emphasis on 10, I will write below why). So, I had to go inside the second main neighboring router, and there to change its Standavatic IP, also 192.168.1.1 at 192.168.1.1 ( And in its secondary (740), set IP 192
168.11.11 (such as a one-alone router). That would come to the moment, for which I need the same subnet, on two different routers. I mean, depending on different conditions, then to one of my router, then to another (where there are There is current moment), so, and all my devices inside are connected by LAN through the sambo, and there I need static IP.The android and linux, it is easily prescribed to the static (such as one device, despite which router, will have address 192.168.10.101 , second, respectively, 192.168.10.2, etc., but not everything, so riddling, in this well-established, configured mechanism, well, does not want to fit Windows. Made that the static is prescribed there, only an adapter (in the sense Where it would not connect, IP will always be, one and the same, in my case 192.168.10.3 (and if the router is not, in the subnet of H.H.x.10.x, there is no need, and speech, can not be! ). Delated, adjusted, I for the sake of Windows, both of my router in IP192.168.10.22 and 192.167.10.11 for the sake of Windows 192.168.10.3.
So she (Windows), infection, seeers, does not want to take it out of two routers (not at the same time, but in turn naturally). With one way or yes, there is no, reconnecting on the second router, then immediately in the tray with the antenna fay, Exclamation mark in yellow triangle- "No access to no!". You have to go back to the settings of the wireless adapter parameters in Windows, and incl. Automatic, incllated).
All the cheese, it is for the statics. There is a way to adequately forcing Windows to work out of static. However, with forced, reconnects between two routers?
While he wrote, she shouted in his head, another thought, let us appoint both routers with my same IP, it could be so, the infection will work normally. If anyone else has ideas, I will be happy to listen, smart people (the very idea is on the outcome! ).
Thank.
