NETGEAR WNDR4500 v3

Under Construction!
This page is currently under construction. You can edit the article to help completing it.

Write a short, relevant description of the device. Include a technical overview, but avoid marketing buzzwords/useless stuff. Two to four sentences is about right. A picture is good, too. Edit the page to see how to add pictures.

FIXME Any text with a light background (like this one) provides instructions for creating the Details Page. When you have filled in correct/useful information (instead of any template that's there) remove the instructions, as well as the <WRAP> that encloses it.

Generic Router

FIXME

  1. This is an empty template that suggests the information that should be present on a well-constructed Device Page. This means, that you have to fill it with life and information.
  2. There are several “fixme” tags with text on a light background (like this text) throughout this template. As you fill in the page, remove those tags so that people can judge its completeness.
  3. When there are no more “fixme” tags left, delete this one too, along with the <WRAP> that encloses it.
  • Please include only model specific information, omit bla,bla and put everything generic into separate articles
  • If you have no time to write certain stuff, link to docs
  • base-system should lead the way, do not explain this again
  • DO NOT provide a complete howto here! Instead groom the general documentation.

FIXME

  1. The tables below are automatically generated, once the correct filters for Brand and Model are set.
  2. If the tables below show information for NETGEAR WNDR4500 v3, everything is OK and you can delete this text and the <WRAP> that encloses it.
  3. If the tables below contain “Nothing found”, it means that either
    1. the dataentry page for NETGEAR WNDR4500 v3 is missing. Please create a new dataentry page first, then reload this page. The tables should then contain $something. If they do, delete this text and the <WRAP> that encloses it.
    2. filters are not set correctly. Most common reason for “Nothing found”: The dataentry does not contain a Version, but we are filtering here for version → Please edit this section and adjust the filters with the proper Brand, Model and Version. In case the dataentry does not contain a version, delete the line filter : Versions~. Just try, it's easy. The tables should then contain $something. If they do, delete this text and the <WRAP> that encloses it.
  4. If the tables still contain “Nothing found”: Don't panic, calm down, take a deep breath and contact a wiki admin (tmomas) for help.

None at this time.

Install OpenWrt (generic explanation)

It has been reported that flashing factory image to WNDR4500v3 using Netgear UI causes router to be bricked when OpenWrt router is subsequently powered down.

Unbrick & install instructions

Summarised instructions to apply both the factory and sysupgrade images is as follows:

  1. Use the Netgear UI and flash the squashfs-factory.img to the router. The router will automatically restart when the install is complete.
  2. Next, SSH into the router at 192.168.1.1 and execute the following commands to install the 21.02.1 squashfs-sysupgrade image release in this example:
          cd /tmp
          
          wget https://downloads.openwrt.org/releases/21.02.1/targets/ath79/nand/openwrt-21.02.1-ath79-nand-netgear_wndr4500-v3-squashfs-sysupgrade.bin
          
          sysupgrade -v /tmp/openwrt-21.02.1-ath79-nand-netgear_wndr4500-v3-squashfs-sysupgrade.bin
  1. You will be disconnected. The router will eventually restart and OpenWrt is ready for use. The router should no longer brick itself when powered off.

FIXME Find out flash layout, then add the flash layout table here (copy, paste, modify the example).

Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout.

FIXME The instructions below are for Broadcom devices and only serve as an example.
Remove / modify them if they do not apply to this particular device!

This section deals with

  • How you install OpenWrt from a device freshly opened
  • The steps required such as reset to factory defaults if the device has already been configured

Note: Reset router to factory defaults if it has been previously configured.

  • Browse to http://192.168.1.1/Upgrade.asp
  • Upload .bin file to router
  • Wait for it to reboot
  • Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1 if LuCI is installed.

Specific values needed for tftp

FIXME Enter values for “FILL-IN” below

Bootloader tftp server IPv4 address FILL-IN
Bootloader MAC address (special) FILL-IN
Firmware tftp image Latest OpenWrt release (NOTE: Name must contain “tftp”)
TFTP transfer window FILL-IN seconds
TFTP window start approximately FILL-IN seconds after power on
TFTP client required IP address FILL-IN

generic.sysupgrade

FIXME These are generic instructions. Update with your router's specifics.

  • Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
  • Upload image file for sysupgrade to LuCI
  • Wait for reboot

If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:

  • sysupgrade
  • mtd

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

sysupgrade

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

mtd

If sysupgrade does not support this router, use mtd.

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

generic.debrick

From Link to Owrt forum

  1. Get “nmrpflash” via github. This is THE tool for repairing corrupted netgear routers (worked better than netcups original support advices).
  2. You need to install npcap-1.31 with winpcp legacy for the program to get the need libraries.
  3. Download the original firmware which is e.g. “WNDR4500v3-V1.0.0.58.img”.
  4. Rightclick with pressed shift in your folder in which you have all the tools stored and click on powershell.
  5. do .\nmrpflash.exe -L
  6. poweroff your router with powerclickbutton (you should be connected with lancable)
  7. do .\nmrpflash.exe -i net12 -f .\WNDR4500v3-V1.0.0.58.img BUT changed net12 accordingly to what you saw in the last command with -L. After that turn on power on router again and let it work. When command prompt says it power of and power on the router again.
  8. Now you can get to your normal router software.

Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

FIXME Please fill in real values for this device, then remove the EXAMPLEs

The default network configuration is:

Interface Name Description Default configuration
br-lan EXAMPLE LAN & WiFi EXAMPLE 192.168.1.1/24
vlan0 (eth0.0) EXAMPLE LAN ports (1 to 4) EXAMPLE None
vlan1 (eth0.1) EXAMPLE WAN port EXAMPLE DHCP
wl0 EXAMPLE WiFi EXAMPLE Disabled

FIXME Please fill in real values for this device, then remove the EXAMPLEs

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.

Port Switch port
Internet (WAN) EXAMPLE 4
LAN 1 EXAMPLE 3
LAN 2 EXAMPLE 2
LAN 3 EXAMPLE 1
LAN 4 EXAMPLE 0

FIXME

  1. This table is automatically generated, once the correct filters for Brand and Model are set.
  2. If you see “Nothing.” instead of a table, please edit this section and adjust the filters with the proper Brand and Model. Just try, it's easy.
  3. If you still don't see a table here, or a table filled with '¿': Is there already a Techdata page available for NETGEAR WNDR4500 v3? If not: Create one.
  4. If you see a table with the desired device data, everything is OK and you can delete this text and the <WRAP> that encloses it.
  5. If it still doesn't work: Don't panic, calm down, take a deep breath and contact a wiki admin (tmomas) for help.
