Linksys E2500 v1
The Linksys E2500 was a router released by Linksys around April 2011. It features a Broadcom BCM43236 dual-band wireless chip. It has 4, 10/100 ethernet ports, and a single 10/100 WAN port.
Supported Versions
Hardware Highlights
Installation
OEM easy installation
Login to the default Linksys E2500 Web Interface (Default factory setting is http://192.168.1.1/).
Next, go to Administration, and then click the Firmware Upgrade option in the sub-menu. Click browse, upload the .bin you downloaded from above, click “Start Upgrade”, and wait for the router to reboot.
OEM installation using the TFTP method
Upgrading OpenWrt
LuCI Web Upgrade Process
- 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
Terminal Upgrade Process
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:
sysupgrademtd
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
Debricking
Failsafe mode
Basic configuration
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
Network interfaces
The default network configuration is:
| Interface Name | Description | Default configuration |
|---|---|---|
| eth0.2 | WAN | DHCP Client |
| eth0.1 | LAN ports (1 to 4) | 192.168.1.1/24 |
Buttons
→ hardware.button on howto use and configure the hardware button(s).
The Linksys E2500 has the following buttons:
| BUTTON | Event |

Notes
- Ethernet is tested to work fine. This router would make a great Ethernet only router. Wireless does not work on this device.
