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://,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 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 problems not being able to log into the DD-WRT admin panel after the firmware, go to the 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: gateway: If the addresses are different, then the easiest option is to restart the network card (on and off then the network will again request the addresses via dhcp), if this did not help, manually enter, for example, ip, mask: gateway: 192.168. 1.1 and try to enter the browser again at
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.

AT: How to properly flash the router?
  • 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, 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 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.

Q: How to set up a router in repeater mode?
ABOUT: Instruction

Q: How to reassign a burned out WAN port to a LAN?
ABOUT: We read here .

Q: How to get the maximum WiFi speed on routers with N mode
ABOUT: We read here .

Q: It is written on the official website that I lose the warranty when installing DD-WRT. This is true?
ABOUT: Theoretically, yes, but you can flash the stock, and most routers will be out of the box.

Q: I need a built-in OpenVpn, is it in this firmware?
ABOUT: Yes, but only in firmware for routers with more than 4 mb. of memory. (You can find out how much flash memory in your router model, for example, in WikiDevi )

Q: I need the router to automatically turn on and off WIFI on a schedule, DD-WRT can it?
ABOUT: Yes that's instruction

Q: DD-WRT does not allow the provider’s local resources (personal account, etc.), what to do?
ABOUT: You just need to remove one tick. instruction

Q: How to change the TTL value on the router?
ABOUT: Here is instruction

Q: How to enable multicast on DD-WRT?
ABOUT: Instruction

Q: How to make the router work as a switch, but with wifi?
ABOUT: Instruction

Q: How to make the router automatically restart at the right time?
ABOUT: Instruction

Q: If you don’t see the neighboring computers on the router’s local network (for example, on Samba)
ABOUT: Instruction

Q: I switched the language to Russian and in some places (for example, on the tab of the MAC filter of a wireless network) there are cracks.
ABOUT: Yes, this is a bug; it is very easy to overcome - by forcibly switching the page encoding in the browser to UTF-8
(for example for chrome there is an encoding menu plugin)instructionAlso, this bug is missing in the version of r27086 and earlier.

Q: How to activate the firmware on Ubiquiti routers.
ABOUT: No Only buy a license for dd-wrt on the official site. There are no working key generators.

Q: My provider has local sites in the .local zone, having trouble accessing them. How to be ?.
ABOUT: Here is instruction

Q: I need to block a site on my home network, for example, youtube. How to do it?
ABOUT: Here is instruction

Q: I heard that using dd-wrt, you can somehow access Pandora, HBO Now, Spotify, Amazon Video and Netflix outside the US without using vpn. How?
ABOUT: Here is instruction

Q: I need to get internet via wifi and distribute it as usual, that is, connect the router with a "client". Can this be done?

But you need a white ip on the router so that you can log into the router remotely.

Rep: (1)
all this is done the address is static, it cannot enter and everything comes from the locale

Rep: (20)
there is such
turn off the firewall on the router and try without it
if it doesn’t go, it means with IP via nat or something like that, with mobile providers it happens.
How does the router connect to you?
VPN PPPoE or how?

* yurok0908,
Exactly at the router static and white IP? Actually, its "static" is not the main requirement, it should be "white" (public, without a clue how they are also called), and if you specify the port directly during access (see the screen - an example of the router settings just above stp101)?
in the browser, in the address bar, enter something like the following XXX.XXX.XXX.XXX:8081, where XXX.XXX.XXX.XXX is the IP address, and 8081 is the port number (wrote the same as in the screenshot from stp101, in general, it can be anything, but standard for http 80 and 8080, with others - you will probably need to specify the port explicitly as in my example)

Yurok0908 @ 01/03/2017 02:56*

It is necessary to register a static entry arp
arp -i br0 -s FF: FF: FF: FF: FF: FF
So write in the "Run", without changing anything. It helped me.
Then you can use any program for WoL.

In order for DD-WRT to skip the multicast, you need to remove the checkmark from "Multicast stream filtering" in the "Firewall" section

A small instruction on how to do dhcp redirection on DD-WRT (it turns out something like a switch, and the same is done via wifi)
For example, we have a router with the address, and for some reason we need the second router with dd-wrt to work as a switch, for example, we need this router to distribute the wifi signal, but also the computers connected to the first on the same network with our wifi.
This is done very simply, see the screen:
example for
Attached Image

The IP address in the local network is the address at which it will be possible to access this router (you need to set it different from the address of the first router, but on the same subnet)
All, then just set up wifi as usual. With this setting, the cable from the main router can be inserted into any port, not necessarily in the wan port. Computers connected to this router will receive ip addresses from the main router.

Well, this is for the Chinese market, so I doubt that the firmware can be found.
But you can try to build OpenWrt for this router using the openwrt image builder, maybe it will.
It is also possible that the same model for the European market is simply called differently; google tp-link models with wifi ac may be lucky.
