Question about Linksys Wireless-G Broadband Router

1 Answer

Setting Up a Wireless Network

I recently moved into a house that has cable modem internet access. There is a cable coming out of the wall that goes into a small black box, provided by Comcast, and from there a blue cable runs into my desktop computer, its a USB cable. Its called a Motorola Surfboard Model: SB5120.
In my old apartment I had broadband internet access. It was a plug that looked like a phone cord but slightly larger. I was using a Wireless-G Broadband Router by Linksys Model: WRT54GS, to get internet access to my laptop.
I tried hooking this router up with the cable modem by running an ethernet cable from the Surfboard to the router and then into my laptop. When I get a list of wireless networks in range on my laptop the router shows up with Excellent strength but I can not gain access to the internet.

So My Question Is: Is there a way to use my old Broadband Router with cable modem access or would I need to by a Router designed to be used with a cable modem? OR Is there an accessory that would allow me to use my old Router with cable modem?

Thank you for your help!

You can still use your existing Linksys router with your cable modem. In fact the router your have is designed to work with DSL/Cable Broadband connections.

1. Make sure to properly connec the devices in your network. Modem will be connected to the Internet port of the router. Then, laptop will be connected to one of the 4 Ethernet ports of the router. For initial setup of your router with modem, you need to hardwire laptop to the router.
2. Press and hold reset at the back of the router for about 15 seconds.
3. After 15 seconds turn off the router and then turn off the modem. Wait for a minute.
4. Power on modem and wait for the lights to be ready.
5. When modem lights are on, turn on router.
6. There should be 4 lights on. Power should be steady green. Internet, WLAN and Ethernet port.
7. Checked if you have Internet connectivity on your laptop while it is wired to the router.
8. If Internet is working, disconnect laptop from wired connection to the router and check available wireless network that laptop can detect.
9. The default wireless network name that the Linksys router broadcasts is "linksys". Connect to it which is an unsecured wireless network.
10. Once you are successfully connected, check Internet.

Hope this helps!

Installation speed and simplicity Installing a wireless LAN system can be fast and easy and eliminates the need to pull cables through walls and ceilings. Components of a wireless LAN To set up your Wireless network at home you need to have the following:

Access point (router)
Access points (routers) are two-way transceivers that broadcast data into the surrounding environment. Access points act as a mediator between wired and wireless network. Most routers have a built-in DSL modem that will allow you access to a high speed DSL internet connection. The ISP (Internet Service Provider) you have chosen normally supplies a modem/router with the subscription to their services. Read carefully the documentation supplied

Setting a wireless router yourself


Setting up a wireless router is easy and allows you the access to Internet, files, printers, plus much more, from virtually any location in your house or yard. Before you shake your head about setting up a wireless router on your own, trust me, if I can do it, anyone can.

Here are some simple steps for setting up your wireless router.

Select the correct wireless router for your needs.

There are basically (3) wireless networking technologies on the market today; 802.11a, 802.11b, and 801.22g. So what are the differences between these wireless technologies?

802.11a wireless protocol is the oldest version of wireless networking technologies currently available. While you may find 802.11a wireless hardware at discounted prices, I would strongly urge you to avoid them. 802.11a is limited in range and capacity versus 802.11b and 802.11g. So why set up your first wireless network with the oldest technology.

802.11b wireless protocol (11Mbs) is by far the most common wireless technology in use today. If you select this wireless protocol, you will be fine. But why not start with the latest and greatest wireless protocol currently available?

802.11g is the best wireless technology on the market and all new computers with built-in wireless cards utilize this protocol. 802.11b wireless protocol was superceded by backwards compatible 802.11g (54Mbs). What this means is that if you have an 802.11b card on some of your computing devices, you can use an 802.11g wireless router without the need to replace your wireless card. If you have the option, I would strongly recommend purchasing 802.11g cards for your computers as well to get the maximum benefits of this wireless network technology.

Connecting your wireless router

Before starting, be sure you have a paper copy of all instructions or the router manual in front of you. Sounds simple, I know, but you would be surprised how many people neglect this basic step. Ok, let's get started!

The first step will be to power down your DSL or cable modem. This will be accomplished by unplugging the devices from the electrical outlets.

Next, connect the wireless router to your modem. I would recommend keeping the distance between the router and modem as close as possible. I have both modem and wireless router setting side by side on my desk.

Included with the wireless router, you should have a short cable. This is your network cable. Plug the network cable into the wireless router in the port labeled INTERNET, WAN OR WLAN. This designation varies depending on the brand of wireless router you purchased. It does not matter which end of the network cable you connect to the router, since the same type of connector is used on both ends.

Once you have connected the network cable to your wireless router, connect the other end of the cable into your modem. Your modem will only have one port available. You will hear a "click" when a secure connection has been established.

You can now re-insert the cable which provides your Internet access back into your DSL or cable modem.

At this point, you will want to power up your modem. The modem should always be powered up first. Allow a few moments for the Internet connection to synchronize with the modem.

It is now time to configure your wireless router. Temporarily disconnect the network cable from the router and modem. Once you have completed this, connect the network cable to any port on the wireless router not labeled as INTERNET, WAN OR WLAN. You will probably have at least 4 open ports; any one will do. Next, connect the other end of the network cable to your computer. This may seem confusing, however, you need a direct connection between the router and computer to permit configuration.

On your computer, open up an Internet browser and enter the address which corresponds to your specific make of wireless router.

ROUTER ADDRESS USERNAME PASSWORD

3Com 192.168.1.1 admin admin

D-Link 192.168.0.1 admin

Linksys 192.168.1.1 admin admin

Microsoft Broadband 192.168.2.1 admin admin

Netgear 192.168.0.1 admin password

Once you have entered the address into your browser, you will be prompted to enter a username and password. Reference the chart for your respective information. While in the configuration mode, you will have the option to change your password, which I strongly suggest.

Next, you will need to set your network id or SSID. This name does not have to be lengthy, but choose something that is unique and but easy enough for you to remember.

Protecting your network. You will also have the option to either secure your network or leave it "open". By leaving your network "open", anyone within range of your wireless router signal will be able to access your network. If you live in a location in a development or apartment, there is a good chance someone will be riding your network..using your Internet access for free and degrading your access quality. It is a good rule of thumb to secure access to networks and computers whenever possible.

To secure your network, select the WEP tab or option. WEP stands for Wireless Encryption. You will be prompted to enter a password or passphrase. We have already addressed changing your administrator password from the default, so let's move on. Be sure to select Apply or OK after making your selections.

Disconnect the network cable from your computer, and reconnect as before. One end of the network cable goes into the port on the wireless router marked INTERNET, WAN, or WLAN, and the other end connects to your DSL or cable modem.

After a few brief moments, an icon should appear on your desktop alerting you a wireless network has been detected. Right click on the icon and select "View Available Wireless Networks".

If you do not see your network, click on the Refresh button from the menu. Once your network is visible, click on it.

If you have WEP protected your wireless network, you will be prompted to enter your password or passphrase. If you have chosen to leave your network unprotected, you will be cautioned that you are attempting to access an unsecured network. Select your network and press "Connect".

If the walls in your house are made of lathe and plaster or concrete block, then the performance of WiFi through all the walls in your house will be very bad. The signal that you are receiving from your neighbor's modem is probably only going through two walls (the outside wall of their house and the outside wall of your house), while the signal from your modem is probably going through at least 4 or 5 walls.
I suggest that you do not buy a new modem, but buy a wireless access point, a spool of CAT6 cable and two Leviton RJ45 wall jacks. Run the CAT6 cable from the modem to your bedroom, install the Leviton RJ45 jacks on both ends of the cable, and then connect the wireless access point to the the jack in the bedroom and the modem to the jack near to it.
This will expand the wireless coverage in your house and allow you to buy much better wireless device than QWest would ever sell to you.
Here is a suggestion for Wireless Access Point.
You can buy the CAT6 cable and Leviton RJ45 jacks at Home Depot or Lowes.

The ploblem is In need the solution of wire less network to build in the big house.


I presume you need Internet access in this house using a wireless network.
The best place to locate the wireless router is in a spot centrally located where the radio signals can reach the rooms where the computers are located. The DSL or cable modem/connection would also need to be in this area so it can connect to the wireless router.
If the wireless router is in a multi-storey house and the floor slab and walls are concrete and/or brick, then the radio signals will be impeded and the signal strength to some rooms will be weak.
In such circumstances, it maybe better to install network cables from these rooms to the wireless router, or install wireless access point repeaters to increase wireless coverage.
If you are not sure how to setup and install this network, then I suggest you get help from a computer savy friend or from your computer friendly shop.

Wireless router says its working laptop says no its not


Your sister was accessing the wireless access point at school which is connected to the Internet/WEB access via a router and the school's broadband service provider.
For you to access the Internet using your wireless adapter on your laptop, you need your own wireless access point and connect it to a broadband ADSL or cable modem and then connect it to an Internet Service Provider. Some Internet Service Providers (cable and ADSL) can supply a combined modem/router/wireless Access point.
If you already have a broadband modem all you need is a wireless access point/router. You only need to configure the wireless access point and your wireless adapter so they will communicate with each other. Folow the instructions in the manuals.

1) Are you sure you're connecting to YOUR wireless network? From my own house, I can access 5 different wi-fi networks, 3 of them unsecured. I've even logged into two of them, unintentionally.

2) Check all of your cabling connections that they are tight and
secured. This includes the cables from the wall to your modem,
between the router and modem, and from the router
to your PC. Ensure that your LEDs are not lit Red or not at all.

3) Ensure that you are using Ethernet cables and not telephone
cables between the router and PC. Ethernet
cables use a wider RJ-45 style plug using 8 wires where
telephone style plugs use the smaller RJ-11 style plug using 4 to
6 wires.

4) Ensure that your Ethernet adapter is enabled. Check the System
Tray at the bottom right of your display to see an icon that looks
like a monitor. You can click on this to see the status of
your Ethernet adapter. Also in Control Panel > Network and
Dial-Up Connections, you can examine the state of your Ethernet
adapter.

5) Firewalls. Your desktop firewall(s) may be blocking your internet access. Check them.

6) You may not be completely blocked (only web traffic - port 80 - blocked). Go to Start > Run and type CMD. At the DOS prompt, type ping 192.168.1.1 (should be the default IP address of your router). If you get a response, your PC is talking to the router. If you get "timed out", then they are not talking, for some reason. If successful, try pinging an external address, something like ping www.fixya.com, and see what happens.

This is what I would do I would connect the wireless to the internet direct and allow all PC with wireless capabilities to access the net through that wireless irrespective to where I place the wireless router.  Alternative I would link the cable on on the second floor the one you use for the PC to access the net to access the the wireless it should automatic allocate IP addresses as each machine accesses the network.  The speed of that wirless is decreased as each wireless PC comes on line.
