It could be a problem with the card or port itself, but it could also be a problem with the drivers. Check to see if the proper drivers are loaded for your network card - for example, if there was a recent network driver update download from Microsoft, uninstall it.

If this is not the case, try unistalling the drivers entirely, and then reinstall them from a fresh copy either from the original CD or downloaded from the vendors web site.

If that does not help, it could be a problem with Windows - I'm guess it's Windows XP? If something has messed up the TCP stack, Dial-A-Fix would be able to rebuild the stack for you.

If none of these help, then a physical failure is probably the problem. You could then replace the NIC (network interface card), or if onboard (that is, part of your motherboard and can not be removed), disable it in the BIOS, and add a PCI NIC card to the machine.

No internet or lan lights on? Tried reset, hard reset. All other lights, power, wireless, router are on and green. No lights on internet and lan connection. I have tried another wireless router and have no...


Hi there,
The LAN lights will only turn on once you have an Ethernet cable connected to it and the other end of the cable is connected to a working computer.
If you already have a computer connected to the Ethernet port of the router via an Ethernet cable and the lights are still off. Check if the computer you have connected recognizes a network via LAN.
If the lights on the router are still off and the computer doesn't recognize a network then that means that the port for the ethernet of your Router is bad and sadly there's no way of getting that fixed but to have the router replaced.
Otherwise if the lights are off and the computer recognizes the Network and lets you connect to the internet or other computers on the same network then its just the LED of the LAN light that's broken and I think you can live with that.
Hope this helps!

How Can One Cable Modem Work With Two Wireless Routers? By Terry Stockdale Leave a Comment In How to Fry a Wireless Router or Two, I wrote about my brother's experience frying a pair of wireless modems in a lightning storm. Last week, I talked about what had happened, why it happened, and what he could do to prevent the problem in the future (this was the third set of routers, plus he lost a computer motherboard in that storm).
This week, we'll look at his network layout, and why he could not get the network to set up properly.
To summarize the situation, he has an office an a shop, with computers on his network in both locations. Some connect via wired connections (Ethernet), while others use wireless connections. His Internet cable comes into the office first.
In the past, he first used Linksys wireless routers. Then DLinks. This time, he chose Belkin wireless routers.
The incoming cable (standard cable-company RG6 coaxial cable) connects to the cable modem.
Then, the cable modem connects to the WAN (wide area network "Internet") connection on the router.
The local wired ports on the router provide connections for two wired computers. Notebooks connect via wireless connections. Finally, one wired connection on the router is used to connect an Ethernet cable that runs 250 feed to the office from the shop.
That cable was the lightning problem, as it runs outside in a conduit just a little bit underground. Effectively, he's got a 250 foot antenna looking for the electromagnetic pulse from a lightning strike. Most of us don't worry about that because our equipment is so well grounded in the house, plus the Ethernet cables we use are much shorter lines. Even if we have underground cable company lines running from their switch boxes to our houses, those lines are usually only exposed about 40 to 50 feet before they enter the dwellings.
Back to the situation. When he hooked up his replacement routers, the router at the shop immediately worked. Not so, on the router in the office. The Ethernet light and the Activity light just poounded away, blinking and blinking rapidly. But, nothing connecting to the router could get to the Internet.
If they connected a computer directly to the Ethernet cable in the office, without running it into the router first, it worked just fine. But, with the router in place, it didn't work.
The problem was the way he connected the two routers. The problem is that there is no Out Of The Box connection that will work reliably. At least one thing, usually two, has/have to be tweaked one way or another.
As one might guess, the easiest way to connect would be to connect one router's WAN connector to the cable modem, using Ethernet cable, and then use Ethernet cable to connect one of the Local Area Network (LAN) connectors on that router ot the WAN router on the other computer.
There is a problem with this setup, but it's easily solved. First, if you're using identical wireless routers, as he was, the wireless routers are both trying to use the same IP Address range and subnet mask for their local area networks.
That works fine for the first router, which is connected to cable modem. On the cable modem side, it gets an IP address on the Internet Service Provider's network - often an actual Internet address and not just a private network address. On the local area network, it assigns the IP address range specified in its setup menu. This often varies by manufacturer. In the case of Linksys, this is 192.168.1.x. In the case of the Belkin routers he bought, it was 192.168.2.x.
The problem occurs at the second router. On it's WAN side, it sees a 192.168.2.x network - but it's default setting tells it to give 192.168.2.x addresses on it's local area network side, too. In other words - it's confused. It doesn't know where to find the Internet because both networks are assigned the same addresses.
The solution was to disconnect the second router's WAN/Internet cable, connect to it via a wired computer, and tell the second router to use a different IP address range. We chose 192.168.3.x.
We hooked up the Ethernet cable to the Internet/WAN side of the router again. The router started working fine, normal light blinks for activity, no more confusion. The computers could get to the Internet just fine.
Problem solved.
That solved the Internet connection problem. However, no computers in the office would be able to share files or printers with the shop, nor would computers in the shop be able to share with the office. That was both acceptable and intended, in this case.
It could be done; however, that would require a different configuration on the routers and connections.

My linksys w/2phone ports cannot hook up with the ethernet


Most Cable Internet Service Providers (ISPs) use Media Access Control (MAC) Address authentication to establish Internet connection for end-users. MAC address is a unique identifier assigned to the network adapter/s of the computer.
To set up your Linksys router to work with a Cable ISP, you have to enable the MAC Clone feature of the router. MAC Cloning is a procedure which enables a router to copy the MAC address of the computer registered with the ISP.
To set up a Linksys router with Cable connection, you need to perform four steps using the computer that's been registered with the ISP:
i. Verifying Internet Connection
ii. Connecting the Devices Together
iii. Checking the Router's LEDs
iv. Setting Up a Linksys Router for Cable Internet Connection

Verifying Internet Connection
Connect the computer to the Broadband modem using an Ethernet cable without the router installed. If you cannot get online, contact your ISP. If it's online, use the computer to set up the router.
NOTE: Some cable modems use the USB port. If the physical connection is via USB port, you may not be able to go online via Ethernet connection. Contact your ISP to have the Ethernet port of the modem configured.

kb17251-001_en.png NOTE: The image may vary depending on the computer and modem you're using.
Connecting the Devices Together
After confirming the Internet connection through the modem, connect the modem to the Internet port of the router; connect the computer to any of the four Ethernet ports at the back of the router. For instructions, click here.
Checking the Router's LEDs
After connecting the devices together, check the lights on the front panel of the router. Ensure that the Internet light, as well as numbered light corresponding to the Ethernet port where the computer is connected, is lit. For further instructions, click here.
Setting Up a Linksys Router for Cable Internet Connection

Step 1:
Access the router's web-based setup page. For instructions, click here.

NOTE: If you are using a Mac computer to access the router's web-based setup page, click here.

Step 2:
On the Setup tab, click the MAC Address Clone sub-tab.

kb17251-002_en.png

Step 3:
Select Enabled then click Clone My PC's MAC.

kb17251-003_en.png

Step 4:
Click Save Settings.

Step 5:
Click the Status tab.

kb17251-004_en.png

Step 6:
Check the Internet IP Address. If the Internet IP Address has numbers, this means the router has been properly configured. You should now be able to access the Internet. If you're still unable to access the Internet, powercycle the modem, the router and then restart the computer.

kb17251-005_en.png

NOTE: If the IP address is still 0.0.0.0, click IP Address Release then, click IP Address Renew. If this does not change the IP Address, powercycle the modem, the router and then restart the computer.

Wireless router to modem problems


Since it says network cable unplugged on the computer when wired to the router, you need to check these first:

â Make sure that the Ethernet cable is connected from the modem to the router’s Internet (WAN) port and the computer to the numbered port of the router. The computer should used to be connecting to the Ethernet port of the modem, if not; you should contact your ISP first.
â Make sure that the Ethernet adapter/LAN card on your computer is working properly. You can check that on the device manager of your computer.
â If those are all working fine that would mean the router is not yet configured for Internet access or we can say that the settings for the provider are not synchronized with the router.

To configure the router, you can do these general steps:

1. Connect the computer to the numbered port of the router and the modem to the router’s Internet (WAN) port.
2. Turn off the computer, router and modem.
3. Turn on the modem first, wait for the lights to stabilize then turn on the router. As soon as the lights are stabilized, you can turn on the computer and check for internet connection.

However, if the Internet connection still does not work. That means there are additional settings needed to be done. You can message me about the name of your ISP and I will provide you the specific steps you need.

Enthernet connection


Ethernet connection is a LAN or a CAT cable
One end of that cable will connect at the back of ur router box that u will have with u or u will get it from ur ISP .
and the other end of that cable goes to the back of ur pc in the jack which says LAN or try to plug it in any socket which fits properly.
u will a light that will start flashing at the back of ur back when u plug that cable in
to check whether u system supports ethernet connection or not
1. right click on my computer
2. goto properties
3. goto hardware
4. goto device manager
5. u will find network adapters there
click on the plus sign on the left side of network adapters
plus sign will change to minus
under network adapters look for an ethernet adapter or network controller
or 10/100 or 10/1000 fast ethernet NIC ( network interface card )
if u have one , then ur pc supports ethernet connection
U just have to connect the ethernet cabel to ur router box and at the back of ur pc and u just have to open internet explorer and ur internet would start working...
if u dont have ethernet cable with u or ur system does not have an ether net socket in ur system , u can goto any computer shop and get an ethernet cable and a socket for ur system
If u dont want to do that , u can go for a USB cable connection with ur pc or a wireless connection....
reply back if u face any further problems
