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:

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: 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.

Nothing happens by this instruction.

In that manual, IP: of the network card is written. Why is the card here?

Straight to the Advance Setup option itself. And, therefore, everything in Advanced Setup is not active. A check mark is placed, but after saving the settings it is still removed.

* AstraVE,
This tick opens the additional menu, it is similar to the tick that opens the additional wi-fi settings and there it is also not saved, it just opens the additional menu, the most important thing is that the settings are saved in the drop-down menu. I have another), opened the advanced settings (Advanced settings) and turned on all the checkboxes there, saved, switched to another tab, clicked again on Advanced settings and there all the items I turned on are turned on.

Fucking buggy firmware. Only recently the router rebooted, but after loading it did not connect to pppoe. In the end - 3 hours stupidly there was no Internet, until I entered the admin panel with my pens - "Basic Setup" and did not click "Apply settings" at the bottom. How to solve the fucking connection problem?

Rep: (58)
Guys, how can you make the VKONTAKTE website work? I am from Ukraine, there is something in the firmware connected with VPN, there is something to register there, can anyone help if it’s possible, I’m fed up with browsers to use all sorts of nonsense to log in to VC, thanks
