Question by Lyn: Blinking Power Indicating Light on my Linksys WRT54GS Wireless Router?
Recently I noticed that the indicating light of my Linksys WRT54GS Wireless Router started blinking & the said router stops working. What is this trying to tell me? I asked Linksys but since my router is out of warranty there is a fee for tech support but said that it might be that the firmware is corrupted. How can I rectify/update the firmware when the router is not working?
Thanks.

that’s a good question but I honestly don’t know. I know how to update firmware but I’m pretty sure the router needs to be working. Try typing this question in computerforum.com. those guys should be able to help you.

    CM (Houston) –

    Amazon Verified Purchase(What’s this?)

    My house was prewired with CAT5e throughout however the outlet in the office was across the room from the router and I did not want to string wire to reach it. I had seen these network power line adapters before but was hesitant to buy them as some customers have expressed difficulties going across circuit breakers and electrical subpanels. I talked to Linksys prior to purchase (on account of a router problem I also reviewed on this site, the Linksys EA4500). They told me that they do not guarantee the PLEs across circuit breakers and their success ratio with these units is about 90%.

    My PLEK400 kit arrived a few days ago and they are working very well. The adapters could not be easier to install and in less than 5 minutes I had Ethernet throughout my power lines. These units are basically plug-and-play although I recommend downloading the “PLE400 Utility” from the Cisco site as it installs a PC based User Interface to easily setup additional security, name each adapter, check status, update firmware, etc. One adapter plugs to an electrical outlet near the router and is connected to the router by the provided cable (this becomes the base unit although both adapters are identical). At this point you have Ethernet throughout your electrical lines. The second adapter plugs to a different electrical outlet providing a network connection to whatever you hook up into that adapter.

    In my own application, the office, I plugged the 2 adapters into electrical outlets which and are under the same circuit breaker. The second adapter (the downstream unit) is connected to the network outlet by that wall and therefore connects to my prewired CAT5 system throughout the house. To test this setup, I went to the furthest room from the router, the master bedroom, and I was able to stream Netflix at high quality without difficulty. This is an easy application – one adapter connects to the other one through perhaps 25 feet of power line, all in the same room, and my hardwired CAT5 system takes over from that point forward.

    As I mentioned, the setup above places the two PLE400s under the same circuit breaker. In order to further test the units, I took one (the downstream adapter) to the master bedroom and plugged it to an electrical outlet there and then to a Sony BD player. I could again stream Netflix without difficulty. In this setup I am under the same electrical panel but on two different circuit breakers (arc fault interrupters, no less, which can be finicky) and Ethernet is traveling through 200-300 feet of power line (maybe more) from the office to the electrical panel and from the panel to the master bedroom. I then took the adapter to the upstairs media room. The electrical outlets in this room are fed from a subpanel, a panel that cascades downstream form the main one, and to my surprise, the adapters worked there also (same solid Netflix streaming). As far as speeds/throughput I am not able to provide much information other than video streaming at high quality is stable.

    These adapters worked very well across different circuit breakers, across subpanels and at long distances form the router. Perhaps the fact that my house has good wiring and is just 2 years old helps. I highly recommend these units.

    Dan K “DPK” (NY Metro) –

    Amazon Verified Purchase(What’s this?)

    I bought this for my home theater so that I could hook up all the internet-enabled components. I used to think that when a product was Ethernet-enabled that meant that you had to run 100 feet of Ethernet cable from your router, through the walls, and to your components. That sounded messy to me so I always looked for WiFi-enabled products. I initially thought about buying a bridge instead but my understanding is that the Powerline adapters were faster since they are a wired connection. I can’t verify that but that is what I was told so double check.

    I was also told that for the Powerline adapter kit to work, both outlets must be on the same circuit. I don’t know about you but I am not an electrician and I really do not know what this means. So I just crossed my fingers, bought this product, and hoped for the best.

    The product contains two adapters; one that you plug into an outlet by your router and another that plugs into an outlet wherever your other equipment is located. You also get two Cat5e cables which I find to be a little on the shorter side so you may want to buy a six foot or longer cable. There is no instruction manual included just a small diagram. Honestly, you don’t need an instruction manual because the four-step diagram really sums up the installation process.

    Here is what you do:

    1. Plug the single port end into an outlet by your router
    2. Connect it to a port on your router
    3. Plug the other port near the other equipment
    4. Connect this port to the port on the equipment

    That’s it, no settings to change and you will be online (assuming both outlets are on the same circuit.) All I had to do was go into the TV menu and perform the “connect to internet” setup and the TV recognized the signal right away.

    I highly recommend you spend the extra few bucks and get the four port version because you never know when you will need the extra ports.

    Regarding the circuit breaker issue. My understanding is that the kitchen and the bathroom are on different circuits from the bedroom and living room. Apparently my bedroom and the living room are on the same circuit so perhaps that might be the same for a lot of other people.

    I’m glad I found out about this product instead of just buying an overpriced WiFi adapter for my TV or buying a more expensive Blu-Ray player with built in WiFi. A wired connection is best so try that first before wireless.

    This is such a cool product and I think you will agree. I highly recommend it.

    EDIT: 6-month update 1/9/13: I have never had an issue with this unit since I hooked it up. The signal and performance have remained strong!

    4x faster then wifi connection, Great product., February 25, 2012

    Amazon Verified Purchase(What’s this?)

    I bought this network adapter kit for my Sony Blue-Ray player, which was running/streaming @ 45% of the router signal/wireless. They were very easy to set up.when I first tested the adapters,the signal dropped down to 38%, but then I realized I did not change the wifi/connection setting to a wired connection and wow what a huge difference.Now I can stream movies 4x faster then before.I would highly recommend the Linksys Powerline AV 1-Port Network Adapter Kit (PLEK400).

  4. You have no connection to the router at all?

    The reset button is located on the rear and is recessed slighly into the back of the router. With the power ON, using a pin, push and hold the reset button until all the lights start flashing or, lights start flashing other then the current. Then, unplug the router for 30 seconds and power it back up.

    If the light no longer flashes, then your problem will most like have been resolved. Attempt connection from your computers to the router/internet.

    If the light continues to flash, connect a computer to the router using an ethernet cable; you obviously can’t do this wirelessly. Once you are connected with an ethernet cable, click on Start, and then click Run, and in the textfield type cmd and press enter. At the command prompt, type ipconfig and press enter. Your computer will reply with a few lines of information. The line of interest is the one that reads “Default Gateway.” It should read 192.168.1.1 .

    IF IT DOES READ 192.168.1.1 then you will be able to update the firmware. First, you will need to get an updated firmware file. Once obtained, open your web browser, type http://192.168.1.1 and press enter. For both user name and password, enter admin . A webpage will appear. Click Administration and once clicked, right below that click Firmware Upgrade. There, you can select the firmware upgrade from your computer.

    IF IT DOES NOT READ 192.168.1.1 then Control Panel -> Network Connections (XP) or Network and Sharing Center (Vista & 7). Find your network adapter. Right click it and select properties. There will be a small list of which one line will read “Internet Protocol version 4” or “TCP/IP connection IPv4.” DO NOT USE THE IPv6!. Click the line that has version 4/IPv4 and click the properties buttons down and to the right. On the next page will read “acquire an ip address automatically.” Select the option below it, “Use the following IP address”. For IP Address, enter 192.168.1.5; Subnet Mask, 255.255.255.0; Default Gateway: 192.168.1.1; press OK and OK again. Once completed open your web browser and type http://192.168.1.1. If you are prompted for a username and password, use admin for both. You will then see a webpage. At the top, click “Administration.” Once clicked, right below that link click “Firmware Upgrade.” Here you can upload the upgrade saved on your computer to your router.

    If you are unable to make a connection to your router with the instructions above, time for a new router.

    For Firmware Upgrade, go to this page… http://homesupport.cisco.com/en-us/wireless/lbc/WRT54GS?referrer=www.linksysbycisco.com and halfway down the page to the right click “Downloads.” From there you can proceed in obtaining and downloading your Firmware Upgrade.
