The <RESET> button on this router is not recognized by DD-WRT firmware. Therefore, in place of the so-called "30/30/30 Reset" which requires a fully functioning <RESET> button, other steps will be taken.
This document is written assuming your USR5461 router is running OEM/USR firmware, and your PC is running a version of Microsoft Windows.
Please, read and understand all instructions in this section and whichever flashing method you will use before starting the entire procedure.
1. Disable Media Sensing feature for TCP/IP in Windows – read and implement Microsoft article #239924 "How to disable the Media Sensing feature for TCT/IP in Windows" – http://support.microsoft.com/kb/239924 .
2. Create a new folder on your computer Desktop and name it usr5461. Download/save the selected DD-WRT firmware image file to Desktop\usr5461.
In our example this is "dd-wrt.v24_micro_generic.bin".
3. Connect your PC to a LAN port of the router with an Ethernet cable.
DISCONNECT ALL OTHER ROUTER CLIENTS (WIRELESS AND/OR WIRED).
Do not flash the router over a wireless connection!
4. Reset your USR5461 router to factory (USR) default settings:
- Press and hold the <RESET> button on the router for 10 seconds; release the button.
- Wait until router control lights stabilize.
5. USR5461 default LAN IP address is 192.168.2.1
Your PC LAN interface/adapter will need a static IP address on the same LAN (192.168.2.x) to reliably transfer DD-WRT firmware image onto the router.
Windows XP: Start - Control Panel - Network Connections; double-click on Local Area Connection icon:
In Local Area Connection Properties window, double-click on Internet Protocol (TCP/IP), and set the following static IP address for your PC:
IP Address: 192.168.2.101
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1
Click < OK > button.
6. Start your Web Browser and enter "http://192.168.2.1" in its location/address line to access USR5461 Web UI. USR Setup Wizard will start - it is an introductory configuration procedure you must complete in order to make the router functional:
- Accept the default settings Setup Wizard will display on three successive Web pages.
- Change/Enter the following settings:
- In Setup 2 page, Security section: -Method: "None";
- In Setup 3 page, Router Login section: -User Name: "root"; -Password: "admin".
After you complete USR Setup Wizard, close your Web Browser.
1. Power off the router (unplug the power supply connector from the router).
2. Open a Command-Line window ('Start – Run... – type in "cmd" and press <OK> button):
- Resize the window to cover the right half of your PC display;
- ENTER the following commands:
The dir command will list the contents of usr5461 folder. Check the presence of DD-WRT firmware image file and its size: 1,769,472 dd-wrt.v24_micro_generic.bin
3. Type in the following command but DO NOT PRESS <ENTER> key on your PC keyboard:
>tftp –i 192.168.2.1 put dd-wrt.v24_micro_generic.bin
4. Open a second Command-Line window:
- Resize it to cover the left half of your PC display;
- Type in the following command and press <ENTER> key on your PC keyboard - you should see continuous error messages:
>ping –t –w 60 192.168.2.1
Destination host unreachable.
5. Click on the right Command-Line window to make it active;
- Plug the power supply connector back into the router;
- Observe the left Command-Line window – as soon as you see the first successful ping replay from the router, press for one second <ENTER> key on your PC keyboard:
>ping –t –w 50 192.168.2.1
Destination host unreachable.
Destination host unreachable.
Replay from 192.168.2.1: bites=32 time=3ms TTL=100
This should start tftp file transfer to the router; there will be 7-9 more ping replays like the first one (during this time the file transfer to router RAM completes. At the end, tftp will report in the right Command-Line window:
"Transfer successful: 1769472 bytes in 8 seconds, 221184 bytes/s"
Close both Command-Line windows.
7. Wait 5 minutes after tftp have reported a successful file transfer. During this time the router is flashing the new firmware image into NVRAM, and then reboots, all on its own.
8. Proceed to "After the Flash" below.
Method 2: the factory firmware's web User InterfaceEdit
It is possible to install a generic version of DD-WRT firmware onto an original USR5461 router using the <Upgrade Router> option in USR firmware's Web GUI. The trick is to make DD-WRT firmware image file look like an USR firmware image file, such that the original USR firmware on USR5461 would accept it as an upgrade source. You have to create a custom "USR-like" firmware image file by:
- Adding a special, 28-byte header "USR0…" to DD-WRT firmware image file;
The copy-command performs a BINARY ("/b") copy of the USR header AND ("+") the DD-WRT firmware image file to make a single "USR-like" firmware image file.
Bellow the last dir-command, double-check that the new file is exactly 28 bytes longer than the original DD-WRT firmware image file. In our example:
3. Start your Web Browser, and enter "http://192.168.2.1" in its location/address line to access USR5461 Web UI:
- Click on <Device>: in Upgrade Router section, click on <Browse> button; find and select the new file created in Step 2 (usr5461-13525_micro_generic.bin);
- Click on <Upgrade> button and WAIT until a message appears: "The router has been upgraded" (it takes about three minutes);
- WAIT for a second message to appear: "Wait until router reboots";
- Wait until router control lights stabilize, and then close your Web Browser.
1. Check the current LAN IP address of the router with the ping command in a Command-Line window. Try first USR default LAN IP address: ">ping 192.168.2.1". If you get four successful replays, this is the current LAN IP address of the router. Proceed to Point 4 bellow.
2. If you get four error messages, try DD-WRT default LAN IP address – 192.168.1.1 . Your PC LAN interface\adapter will need a static IP address on the same LAN (192.168.1.x) in order to TCP/IP connect to the router. You have to:
- Change the static IP address of your PC LAN interface/adapter: <IP Address: 192.168.1.101>;
- Change the IP address of <Default Gateway: 192.168.1.1>.
Note: Consult "Preparing to Flash" section, Point 5.
3. In the Command-Line window you enter: ">ping 192.168.1.1". If you get four successful replays, this is the current LAN IP address of the router.
4. Start your Web Browser:
- In its location/address line, enter the current LAN IP address of the router – "http://192.168.x.1";
- The DD-WRT firmware Web UI should open - complete the router configuration as you want it.
1. Download the latest final USR firmware for USR5461 router from USR Web page: http://www.usr.com/support/product-template.asp?prod=5461 .
Currently this is: "USR5461-v.188.8.131.52.8.usr - 1.8 MB - 10-25-06"
Download/save the file to Desktop\USR5461 folder. This file has too many dots in its name – Windows tftp cannot open such a file.
RENAME the file to: USR5461-v3_93_35_08.usr
2. Use the current LAN IP address of the router and the renamed USR firmware image file in the steps above.
