Question about Linksys Wireless-G WRT54GS Router (e125894)

1 Answer

WRT54GS works fine on LAN cables but the wireless signal comes and goes. Will be working fine and suddenly you will be without wireless. Just as randomly comes back on and works until the next time it decides to go away. Might be 20 minutes or 3 hours. Never any rhyme to it. Can this be a driver problem or an inherent problem which has come up with this unit? Can the transmitter chip be replaced? I don't see any dust or anything inside the unit so I don't think it is overheating.

I don't know how old your unit is. Generally, issues that will cause intermittent connection are (1) RFI (radio frequency interference); (2) poor antenna connection; and (3) circuit degradation caused by overheating.

RFI can be caused by certain older cordless telephones (which operate in the 2.4 ghz band), or other similar wireless devices in close proximity to the router. Putting distance between them is the only viable solution (other than shutting down the offending device).

The antennas can be removed, the contacts sprayed with an electronic contact cleaner (QD Brand is available at most major hardware outlets) and reassembled which in some cases may help.

The last, and unfortunately most likely, situation is that the machine is overheating. Unfortunately (at least in my experience over the past few years) this particular router has shown a tendency to run hot and fail, although they usually last beyond warranty period. Dust doesn't have much to do with it. No, the transmitter circuitry cannot be replaced...and even if it could, it would cost you more than a new router.

It is NOT a driver problem, so don't go trying to update/reinstall drivers.

And, lastly, how far the receiving device (ie., computer) is from the router...and what is in between...can have a huge effect on the signal strength on the receiving end. Has anything changed in the environment in that respect?

Hope that is helpful.

Need passphrase---it doesn't work

When you connect a LAN cable from your computer to the Linksys then open a browser and enter the configuration URL
Login = admin
PW = admin
Then go to the wireless setup
The WPA or WPA2 encryption can be setup using a passphrase.
This can be any combination of words and numbers. Eg My computer1 is mad. - This passphrase is used to generate a hexadecimal encryption number. It is easier to remember a phrase than Hex numbers.
You will also need to configure the LAN card in your computer with this passphrase so it can connect to the wireless router. Once the router configuration is complete the LAN cable can removed, it is not needed for wireless connection.

Wireless Router suddenly stopped working.

Try resetting the Linksys back to the factory defaults and configure it again.
Power up the router and press the pinhole RESET button on the back of the router for 30 sec
Connect a LAN cable to the wireless router and open a browser and enter to router's configuration IP address and configure the wireless settings, remove the LAN cable when configuration is completed.
You need to configure then wireless card in the computer/laptop with the router's wireless settings.

How do i connect and get signal?

This is a common problem with Linksys wireless routers and primarily the WRT54G and WRT54GS. For some odd reason they all of a sudden go stupid and forgetful.

The easiest method to revive these routers is to go to the Linksys web site and get the automatic configuration download for your specific model of wireless router.

Hope this helps you

Linksys WRT54GS not working

  1. First you may need to check if the WLAN or Wireless light on the router is on.
  2. Try connecting your ITouch to a different wireless network.
  3. If you can borrow a wireless ready laptop from a friend, then borrow one.
  4. Check if the laptop will be able to detect a wireless signal from router.
Please update me about this matter.
