Question about Linksys Wireless-G WRT54G Router

1 Answer

I have been running a home network for a couple of years with a Linksys Wireless-G Router WRT54G V2, S/N CDF50D617663 and a Linksys Remote Repeater Unit, all with no problems. My internet connection is DSL with a Static IP from Mindspring. I have lost all manuals and installation programs. I will be switching over to a dynamic IP and possibly a new DSL providor. I need to know how to reconfigure my Router.

    I am familiar with how to access the router. What, if any, settings must be changed to switch over from Static to Dynamic IP?

Your router will have an ip address, to find it go to the command prompt (in xp click start, then run, type cmd in the box and clickok) and typye ipconfig then hit return, the default gateway address listed will be the ip address of the router, type that into the address bar of your browser to access the router and the pages that control the router. ------------- Use Internet Explorer, it usually works.
JavaScript must be enabled.
Use a computer that is wired to the router.
In the non-working computer, temporarily turn off your software firewall.

If you are using Zone Alarm, right click on the ZA icon in the system tray (lower right corner of screen) and then click "Shutdown ZoneAlarm", and see if this fixes your problem. If this does not work, try the following with Zone Alarm: Open the ZAISS control center, go to Privacy, then temporarily turn off Ad Blocking and Cookie Control, and see if that fixes your problem.

If you are using Noton Internet Security with the Add-on Pack, be sure to turn off the Pop-up Blocker. Some users have reported that they needed to uninstall the entire Norton Add-on Pack.

If you cannot get anything at then perhaps this is not your router's address. Go to "Start" > All Programs > Accessories > Command Prompt.
A black DOS box will appear. Type in "ipconfig" (with no quotes), then hit the Enter key. Look at the "Default Gateway". Is it ? Point your browser to the "Default Gateway", then login to your router.

If the above fails, disconnect your modem from the router, and try again. If this corrects your problem, then most likely you have a "modem-router" rather than an ordinary modem. Check to see if your "modem-router" is using the same 192.168.1.x address space as your Linksys router. If it is, then report back with this problem, and also state the make and model of your modem-router.

If all of the above fails, power down your entire system, unplug it from the wall, wait one minute, then power up and try again.

If all of the above tips fail, you need to reset the router to factory defaults. Power down the router and disconnect all wires from it. Wait one minute. Power up the router, allow it to fully boot (1-2 minutes), then press and hold the reset button for 30 seconds, then release the button and allow the router to reset and reboot ( 2-3 minutes). Power down router. Wait one minute. Connect one computer, by wire, to a LAN port on the router. Boot up system. You should now be able to view the router's setup pages.
thanks.please do accept the solution.thank you for using fixya.keep updated.

    You can do this two ways. Either assign yourself a static IP in the TCP/IP properties of your network adapter or if you router supports DHCP reservations you can enter your host name or mac address (depending on the router) and the router will assign you the same IP every time.

    With most residential internet connections, the internet IP address is dynamic, and therefore changed by the ISP (Internet Service Provider) at various times as they see necessary. Running a server from home on a dynamic IP means that you need to announce to everyone when your IP address changes because they will no longer see your server if it changed. It can be frustrating at times because you have to monitor this constantly to watch for IP address changes. In many cases, at least here in the U.S., to get a static IP address, you will have to pay more for the service.

    When you install a router with a dynamic internet IP address, you just connect the router and it will get the IP address from your ISP automatically, populating the WAN (wide area network) settings on your router. The ISP will assign an IP for your equipment (your internet or WAN IP) and it will also assign a gateway address, subnet mask, and at least two DNS addresses (all look like IP addresses

    If you had a static IP address with your ISP, you would have to enter all of the settings on the router before connecting the router to the internet. Typically, it is all done for you automatically.... dynamically. Ask your ISP for information on obtaining a static IP.

    Is it necessary to have a Static IP Address (WAN) to run a game server? No, not at all. All you would need to do is monitor the IP, and when it does finally change, you just need to tell others of the new address. A static IP is really nice to have, but not required.

    This shows your current IP address.

    On your internal network (between the router and your computers, or LAN / Local Area Network), the process works very much the same as on the internet or WAN. By default, most routers are set to run with DHCP when you turn them on. The IP addresses are assigned automatically by the router on each computer or item of equipment attached to the router (dynamic IP). For most people on home networks, this is wonderful because you do not need to worry about any of the settings, or even care what an IP address is.

    However, when you are running a machine such as a game server, DHCP can cause headaches because IP addresses change. Since you need to open ports on a router for it to communicate properly with the internet, and the settings are loaded by the machine IP address, each time the IP changes, you need to remember to go back in and fix the port settings. This can happen each time any equipment is reset or powered off and on, and it can be really frustrating.

    To get around this, a server should have a "Static" IP address, an address that doesn't change even after you power down and power up again. You can set this in your local network easily. You can disable DHCP on the router, but I would not recommend this since it would mean that you must setup the network connections on all machines manually. You can leave DHCP enabled, and just set a static IP address on specific machines like a server, and DHCP would continue to function with other machines.

    To set a static IP address on a PC, you will need to go in and change network connections. The following guide will describe how to do this on Windows XP Professional, but other versions of windows and operating systems should be similar.

Unable to print from repeated wireless network

If you have done it properly there is no need to bridge networks because there should only be one. The entire idea of a repeater is to simply pick up the signal from the first router and rebroadcast the signal.If you had included the model of the repeater I could have been more specific but as it is, read this: Linksys Official Support Configuring an Access Point as wireless repeater

Can't connect my Ipod touch to my router?

You must be sure to what router you are trying to connect. I understand you have a ZyXel and a linksys. You must have 2 wireless networks. Your wireless network must be secured, so you just have to use the correct password. I need more details. Try this

WAP54G's as repeaters

Are you trying to setup both access point to repeat the signal of the router?
The correct way to setup the AP's as repeater is to access the setup page of your router go to status and go to the wireless subtab, check what is the MAC address that is what your suppose to configure on the AP's not the LAN MAC address which is on the local networks subtab on status.
Access the setup page of the AP's and go to AP Mode, make sure that you choose the repeater and copy down the Wireless MAC address you obtained from the wireless router. To enable roaming, meaning your wireless computer/device will connect to the AP/router closest to its location, change the wireless channel on all three device for example WRT54G will be on channel 1, 1st AP as repeater on Channel 6 and the last AP to Channel 11 but the other settings must be the same(Wireless name(SSID) and Wireless Security).

Note: Setting up an AP as repeater to repeat or extend the signal of another AP that is set to repeater is not recommended since the signal will deteriorate due to the number of hops the packets will be sent.

Hope this will help you setting up those WAP's which for me is quite useful since you can set it up to act as a repeater, AP client and a bridge to a WRT54G router.

Wireless Repeater

There is no option in the router to act as a client. You could set it up as a second access point and connect them via Ethernet, or I believe there is a Linux distribution you can load on the WRT54G that can act in repeater mode, but I've never installed it, so you would have to research that yourself.

Setting up a WAP54G as a wireless repeater with a WRT54G

Requirements for WAP54G & WRT54G Repeater Mode function: * WRT54G: Firmware 2.02.2 or higher * WAP54G: Firmware 2.06 or higher Go to to download the latest firmware upgrades for both devices. . Accessing the Router?s Setup Page: Open a Web Browser (either Internet Explorer or Netscape). 1. Type the IP Address of the Router into the Address Bar ( is the default IP Address). 2. Click GO or press the [Enter] key. The User Name and Password prompt will appear. 1. Leave the User Name field blank. 2. Type admin in for the Password (the default Password). 3. Click OK or press the Enter key. The Router?s Setup page will open: * Click on the Status Tab. * Click on the Wireless sub tab. Write down the Wireless MAC Address and the Channel number values located on this page. If the Encryption Function is Disabled, go to the WAP54G Repeater Setup section below. If Encryption Function is Enabled: Note: WPA (Wi-Fi Protected Access) is not yet compatible with wireless repeater mode. You must use WEP Encryption if you wish to use security options with this configuration. To gather WEP encryption information, click on the upper Wireless tab, then the Wireless Security sub tab. Write down the Passphrase. WAP54G Repeater Setup Be sure that you have the WAP54G plugged directly into one of the WRT54G?s numbered ports for the duration of the setup. Accessing the WAP54G?s Setup Page: Open a Web Browser (either Internet Explorer or Netscape). 1. Type the IP Address of the WAP54G into the Address Bar ( is the default IP address). 2. Click GO or press the Enter key. 3. The User Name and Password prompt will appear. 4. Leave the User Name blank. 5. Type in admin for the Password (the default password). 6. Click OK or press the [Enter] key. The WAP54G?s Setup page will open. 1. Set the Channel value to the same channel as the WRT54G router that was obtained from earlier steps. 2. If WEP encryption was enabled on the WRT54G: * Select Enable for the Wireless Security option. * Click on the Edit Security Settings button and enter the same Passphrase as the one of the WRT54G router that you recorded. Click Generate to populate the WEP key fields. * Click Save Settings to save your changes and close the encryption window. Click Save Settings to save your changes on the Setup page. 3. Next, click on the AP Mode tab. * Select the Wireless Repeater option. * Enter the WIRELESS Mac Address from the WRT54G that you recorded. (Disregard the fact that the page asks to ?Enter the LAN MAC ADDRESS?). Click Save Settings to save your changes. Close your web browser. You can now place the WAP54G Access Point in another nearby location (with its power adapter plugged in) so that it can repeat the wireless signal that it receives from the WRT54G. Notes: * The ?SSID? of the WAP54G does not have to be the same as the WRT54G. This can be used for initial configuration; using a different SSID will enable testing of network connectivity, and will show that the WRT54G is associated with the WAP54G. * If MAC Filtering is configured on the WRT54G, no extra configuration is needed. Wireless clients will still need to be added the MAC Filter list of the WRT54G, but the WAP54G does not have to on the list.
