Linksys Router Troubleshooting Tips
Linksys WRT54G, WRT54GS & WRT54GL Antenna setup: When
using the Super Cantenna with Linksys routers, you must set
your Antenna Selection option within the router settings
to use either the left or right antenna.
The antenna selection option is located within the Advanced
Wireless Settings tab in most versions of Linksys routers.
However, if your particular Linksys router does not include
this option, you can upgrade your router's firmware to enable
antenna selection by following these steps:
Step 1: Determine the current Model and Version of your Linksys
router. The Model number is located on the front and bottom
of the router (eg: WRT54GS). The Version number is located
on the bottom of the router above the serial number (eg:
Step 2: Download the correct firmware upgrade depending on
your Model and Version #. Click on correct link below and
Save to your desktop. Unzip the file.

Step 3: Go to http://192.168.1.1 and
enter your username and password (default is admin/admin).
Go to Administration—>Firmware Upgrade, browse to
the .bin file on your desktop and flash it.
DO NOT interrupt the flashing process and patiently wait
until the router has rebooted.
Step 4: Go
Set both the TX (transmit) and RX (receive) pull down menus
to the left or right antenna.
*LINKSYS WRT54G & WRT54GS (version
5.0 to 7.0) - The firmware on version 5.0 to 7.0 is not upgradeable
at this time. In order to use
your Super Cantenna with these versions, you must REMOVE BOTH
ANTENNAS AND CONNECT THE CANTENNA TO THE RIGHT CONNECTOR WHEN
AT THE REAR OF THE ROUTER.
- Avoid upgrading over a wireless
connection since they can drop out.
- If you're using DHCP on your computer,
renew the lease early or reboot your computer to make sure
it doesn't try to renew
(and possibly unbind) in the middle of the upgrade.
In Windows, you can renew the lease by running "ipconfig /renew".
- Do not hit stop, or navigate away from the upgrade page. Do
not reboot, or unplug the router. Do not do
anything to interrupt the upgrade or
you may end up with a dead brick.
- It will take a few minutes for the firmware to upload. Upload
progress bars are based on time, not the amount of
data uploaded so don't worry if it goes past 100% and loops back again,
or if it doesn't reach 100% at all.
Once the upgrade is finished, you will see a page indicating
the result and then router will reboot on its own.
If the page appears broken or empty, wait for one minute, make sure the
router doesn't have a flashing diag or power light,
then load http://192.168.1.1/ manually.
- If you upgraded from a different
firmware, erase any left over settings and restore the
defaults by going to Administration:Factory Defaults and
choosing Clear NVRAM. Manually re-enter
the settings, do not use the Restore feature.
- If for any reason a firmware upgrade fails, you have to reboot
the router before trying again.
