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 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: 255.255.255.0 gateway: 192.168.1.1. 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 192.168.1.2, mask: 255.255.255.0 gateway: 192.168. 1.1 and try to enter the browser again 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.

Reassign the burned down WAN port on the LAN, in the DD-WRT firmware

Open the addresshttp://192.168.1.1/Vlan.asp
Mirror the values ​​from the portWan on LAN4
Checkbox"W-1 port" remove and put on "W-0 port" .
Checkbox"Port 4-0" remove and put on "Port 4-1" .
What this page looks like

Attention: the page was "hidden" due to security concerns, as incorrect configuration may result in hard reset and flashing.

The second option, reassigning the WAN port via the console
Open the administrative panel of the router and enter the Code:
nvram set vlan0ports = "1 2 3 5 *"
nvram set vlan1ports = "0 4 5"
nvram commit
reset

Rep: (39)
How to get the maximum WiFi speed on routers with N mode and only (2.4 GHz). On DD-WRT firmware

Wireless Network Mode: N-Only (2.4 GHz) (if some device cannot join NG-Mixed)
Channel Width: never mind, but theoretically the HT40 is better. (But not in a noisy area)
Wireless Channel: Auto or 1 , 6 , 11 I recommend 6 to get maximum transmitter power.
Regulatory Domain: You can use your country, but to remove power limits, use United_States (channels 1-13 are available).
TX Power: You can do it all, but remember, the WiFi module can overheat, and the speed may drop. Use 1-2 less than the maximum, the best is the 6th channel. (If you put 30, and 20 is available, the router will simply use 20) (Also in some routers you can install hacked art)
Antenna Gain: Leave 0
Noise Immunity: Enable
RTS Threshold: It does not matter, but if loss of leakage is noticed, I recommend to enable it.
Short Preamble: Enable (VERY old smartphones, etc. may not support)
Short GI: Enable
DTIM Interval: 1 or 2, I use 1. (I recommend 1 if you are using smart TV)
Beacon Interval: 100-200, if there is a VERY lot of WiFi nearby, then leave 100. (Increasing the value to 200, win a few percent of the bandwidth.)
WMM Support: Enable
Sensitivity Range (ACK Timing): 1000-1500 (Default: 2000 meters) If you not use WiFi on long distances, on the street for example, feel free to put 1000,I do not recommend setting 0, this is either Auto in Atheros, or disables this function altogether, in auto mode, the speed decreases, as it takes time to determine the value.
Security Mode: WPA2 Personal
WPA Algorithms: AES

This is purely my recommendation, I use these parameters on my TP-Link TL-WR841ND v9, and I calmly get 150 Mbps in the local network via WiFi.
But keep in mind though the router over WiFi gives 300 Mbps (theoretical speed), you also need to have a WiFi adapter capable of getting the speed provided by the router.

If I'm wrong in something, correct me.

Rep: (9)
* _Danil_,
Thank you, figured out.

Another question: what you need to tweak to IPTV showed more stable.

I mainly watch the Eden playlist (the provider is a complete miser - pushes IPTV of the so-called "Partner" at a crazy price) on Samsbng SmartTV UE40ES6717U via a cord from a router.
They tortured the constant freezing of the image (especially in the evening, when the load on the server increased), we often had to reboot the router.
Therefore, in principle, I reflashed my TL-WR841N v8 on DD-WRT.
The situation has improved: I didn’t do a reboot in a day’s work, but the picture still hangs on many SD channels.
Maybe you can still somehow improve the situation?

Experts welcome, tell me, is there a wps function on dd-wrt? where does it run?



Rep: (9)
At the sale price ($ 5,955 with a two-year warranty) purchased the NETGEAR R6300-100PES router, which turned out to be the second hardware version of the R6300v2 (BCM4708A0 800 MHz; 2 cores; 256 MB RAM; 128 MB ROM; AC1750; Wi-Fi 2.4GHz and 5GHz, including AC; 4 LAN ports and 1 WAN over 1Gbit; USB 2.0 and 3.0 each). I have not dealt with NETGEAR products for a long time and was quite disappointed with the possibilities of the stock firmware, which was also dubbed last in technical support. In order to avoid depression, I installed DD-WRT and the router opened, began to delight, the possibilities of the press, there is something to learn.

I just can not understand with the updates ... I did everythingbased on the DD-WRT Wiki, put the one-year-old recommended build 26138 (ftp://ftp.dd-wrt.com/b…r6300v2-webflash.bin). But I see that the beta is laid out with enviable periodicity, in particular, under my router. Today 29621 of 10 May. How often are people updated? Is it worth it to update or better to sit on the type-stable version and not twitch?
