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)

Esli you are having problems it is impossible to go to the admin panel DD-WRT firmware after, go to the network connections on your computer and make sure that the ip addresses are given correctly: ip: 192.168.1.xxx (last digit may vary) Mask: gateway: If the addresses are different, then the easiest option to restart the network card (.. On and off again when the network asks for dhcp addresses), if this does not work, enter manually, for example ip, mask: Gateway: 192.168. 1.1 and try again to enter the browser to the address
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: You just need to remove one tick. instruction

Q: How to change the TTL value on the router?

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.

* ash_grey,
Now there is nothing, earlier it was possible to generate a key. Right now we've changed the activator, and you can’t do this anymore, at least with the old generator it no longer works. Although there are craftsmen who assemble the dd-wrt firmware manually, and, moreover, already activated.

I use these parameters on my TP-Link TL-WR841ND v9, and I quietly receive 150 Mbps in the local network via WiFi
I have right nowTP-Link TL-WR841N v8 - but when installing the latest stable firmware from the header (as well as the test latest and other versions of assemblies ...) I can’t configure Wifi
What is the difficulty? Network devices see. But they can’t connect to it ... Encryption is disabled. I chose different operating modes and channels - the effect is the same (((
Here's what for example on the phone

The same story is on the rest ... And on the stock firmware everything works and all devices are connected ...Which way to look?
And yes, how to configure on this assembly to turn off Wi-Fi on a schedule during the day? There is a possibility? Or just have the ability to reboot the router only? I didn’t find the settings just ... Or maybe this is done with scripts and / or plugins?
There are no answers in the branch on the device, as in FAK ... Maybe someone came across a similar one?

Yesterday, DD-WRT delivered the same model and revision. The network has risen. See the settings carefully. I can share screenshots, if that, but also individual settings depend on the operator.
Did you change the IP of the router?

No, everything is defaulted ... Only with the channel settings was played - the name of the access point and protocols. Share screenshots pliz. Maybe there will need to be changed there ... Flash memory was not increased, was it native to 4 MB?

1. IP address of the router (for some operators it is important that it is, TP-Link usually has
2. The MAC address of the router (if the operator has a binding, but earlier it was cloned, then after the flashing, clone)

OK, I'll try in the evening) Question - why do you have 2 virtual networks via Wi-Fi? It turns out that you need to create at least one campaign? Or is it enough to turn on Wi-Fi and set up one? I don’t need to create multiple wireless networks ...

Rep: (574)
And yes, how to configure on this assembly to turn off Wi-Fi on a schedule during the day?

Or maybe this is done with scripts and / or plugins?

Of course you can, it's Linux. The command to disable and enable the wifi network interface looks like this: ifconfig ath0 down and ifconfig ath0 up (ath0 or something else you may have, take a look in the admin section at wifi, there the name of the interface lights up)
If we want schedules, then create a cron task, for example, this: 53 6 * * 2 ifconfig ath0 down - disable at 6.53 every Tuesday.
We edit it like this 53 - minutes, 6 hours, the first * is the day from 1 to 31, the second * is the month from 1-12, then the day of the week starts from Sunday, it is 0.
And we throw the commands in "Administration" - "System" - "Additional tasks Cron": 53 6 * * 2root ifconfig ath0 down (will not execute without root)
P.S. For all this to work, you must first set the ntp server address and time zone.
Accordingly, you can turn on and off not only wifi, but for example a wan port or lan ports, substituting the desired interface instead of ath0.

In the new versions, all this is right in the interface.

Hello! I have "happiness" in the form of a router Buffalo WZR-1750 DHP, freewheeling him firmware DD-WRT and got problems. can not configure simultaneous operation of USB modem and DHCP (WAN) network, periodically freezes when you switch the setting from the network to the modem and vice versa. On the "local" forum found as they do with other routers on the factory firmware, tried to drive on their method - it does not work. On the US site I have found the same router, only in his name added to the last letter of D, since the factory-installed firmware DD-WRT, it is different from the version of my last; What if it try to roll? Do not will die if my device?

judging by the wiki, the WZR-1750 DHPD is identical, the only difference is dd-wrt out of the box.

About buffalo, I don’t know what is there and how, but on my routers I use r27086 --- 05/27/2015 everything works stably (is in the header) and it is also in beta, as it looks like it was not selected from the beta version of dd-wrt: D But there are quite suitable releases.

Guys, do not throw slippers, such a question: there is an old Cisco wrt 310. I am completely satisfied with the work, but began to strain the abundance around networks on the same channels ... Native firmware (for states) allows using only up to the 11th channel. And dd-wrt changes the MAC. How can I flash so that the MAC does not crash?

up to the 11th channel.

This is a regional restriction in the USA.
And dd-wrt changes the MAC

In the sense of? Mac becomes zeros or just another?
