Are you able to get to the gui of the router?
If you are able to get inside the routers Gui then that would be a good sign.
Do the following:
1. Go to this site http://www.linksysbycisco.com/US/en/support/WRT54G2/download and select the version. I would suggest you to get the latest.
2. Save it to your desktop. Then extract the file.
3. launch into the router gui
4. Click on Administration then select Upgrade firmware
5. Click on the Browse button and then select desktop then chose the extracted file.
6. Click on the Upgrade button and just follow the on-screen instructions. Normally you just have to select Next.

Hi

The Router configuration is not that much difficult, only few thing you have sure,

Follow the mention bellow instruction to configure and connect to Wifi Router,

  • Plug the network cable ( Mine was Blue ) which comes with the Router Box pack to your computer. The other end goes into any of the Router Ethernet Port ( 1 or 2 or 3 or 4 )
  • Now type in 192.168.1.1 in IE or Firefox or any browser. You will prompted for password which is admin. You must be logged into Linksys Router.
  • Now since your ADSL modem is also having the same IP , we will change the IP address for WRT54G2 Router to 192.168.5.1
  • Under Setup >Basic Setup look for Network Setup and Change Router IP. Change to 192.168.5.1 and Save changes.

After turning the power off for about 1 hour I am unable to connect via my wirless router. I can by pass the router to connect to the internet.


Make sure you update your wireless router firmware..
Use link below to update

http://homesupport.cisco.com/en-ca/wireless/lbc/WRT54G2

Please note:

Linksys is known for alot of problems with there firmwares causing tons for problems ..

I use a linksys wireless router my self & had to unplug the router every 2 to 4 days because it would stop any computers to go on the internet.
I flashed my firmware and put in a 3rd party firmware that has never caused any problems and it gave me tons of features that your linksys firmware did not.

If you are a advanced user you can flash your firmware and put in non-linksys firmware. Not all routers can accept this firmware but you can search up your router model and version to see. Make sure you read all the how to install and all the warnings .. Keep in mind there is a chance no matter if you followed the instructions exactly that it could destroy your router. But the chance is low.

WRT4G2 VI wireless router. I was upating the firmware when the power flashed. I have no access to the router's gui and the router is not broadcasting. I am not getting a dhcp address


do a hard reset for the router by pressing the reset button for 10-20 seconds...
check whether its getting a dhcp address...
if it is still not getting an ip address, then try to assign a static ip address in the range of your router on your computer...

for example...
The default ip address of linksys is 192.168.1.1.............
then assign

IP address 192.168.1.5
Subnet mask 255.255.255.0
Default gateway 192.168.1.1

Also assign a static DNS
Primary DNS : 8.8.8.8
Secondary DNS : 8.8.4.4

Now try to open the GUI of your router...

MY LINKSYS WRT54G2 IS OK BUT CAN'T FIND SERVER.


The Linksys WRT54G2 is Cable/DSL router with 4 port switch. It has many features including a built-in DHCP server. By default, it's IP address is 192.168.1.1, username: blank and password: admin.

Plug in the Modem to the Linksys router's Internet / WAN port then plug your PC's to any of the 4 ports (1,2,3 & 4). The Linksys router once turned ON will automatically provide your PC with IP address starting with 192.168.1.xx (x means number from 100-149).

Make sure that known working ethernet cables are being used. Check your computer's IP adress by going to the command prompt. Start>RUN>type CMD then press Enter. Type IPCONFIG and check the IP address (e.g. 192.168.1.100). Check you PC's network adapter if you don't get an IP address from the Linksys router.

You may opt to reset the router by pressing the reset button at the back for 30 seconds if it fails to give out DHCP.

Cheers!

Upgrade Linksys WRT54G2 firmware failed.


there are 3 variants of the WRT54G2 , v1, v3 and v5 ensure that you choose the right firmware for the variant(its on the bottom of the router)
Go to the US site as this has more uptodate versions of the firmware.
For example v1 in the UK is at 1.0.0.0 dated 2008
v1 from the US site is 1.0.0.4 dated 2009

Power led is blinking after I upgrade firmware


Something went wrong during the upgrade of your firmware. If you were upgrading the firmware from Linksys website you need to call their tech support and have them replace it for you. If you were trying to hack it with a 3rd party firmware you probably need to go buy another one and maybe consider using the firmware it comes with. You cannot restore the device because the flash killed the restore function. Your device is cooked. Put some BBQ sauce on it and serve it for dinner.

I need installation software for a linksys WRT54G2 V1 Router my friend gave me for my birthday but he didn't have the CD


router do not normally need installation software..

you can access their admin software by putting in the ip address into your browser...

if you are running xp go to start > run and type in "cmd"..

when you get the black DOS screen, type in "ipconfig" and look at the results for the ip address of your "Default Gateway"..

go back and type this into your web browser to access the router...

for linksys the default password is admin, leave the username blank

Lost DHCP connection. I changed nothing on my config


Hi,

You may want to press and hold (using a pen or a paper clip) the reset button of the router for 30 seconds and then unplug the power of the router. Turn off the modem, wait for 10 seconds, turn on the modem, and then the router, and make sure that the modem is connected to the internet port of the router and PC to the ethernet port (1, 2, 3 or 4). See if the router will obtain an IP address from the modem. If not, download here http://www.linksysbycisco.com/US/en/support/WRT54G2/download the latest firmware for the router.

Ensure that you download the correct version for the router.
