Question about Belkin (F5D72304F5D7000) Router

1 Answer

No Lan/WAN connection

I suddenly lost internet connection on my home network, when I discovered that none of the 5 ports on the back are working. I can still access the router config through a wireless connection, but it appears that all 5 ports have been disabled. The odd thing is that all of the port lights are on even though there aren't any cables connected. Any thoughts on what might have happened and is there anything I can do? I'm assuming I'm going to need to get a new router, but am hoping there may be a way to fix it.

Thanks in advance for your help!

Re: No Lan/WAN connection

Unplug the router, wait 2 min, and plug it back in. If that work, on the back is a small hole, marked RESET. Using a pencil, or straightne out a large paperclip, press that the button inside gently. Hold it for 30 sec. Release and unplug the unit. Shut down the whole network. "Starting from the wall", power up the modem, wait 2 min, power up the router, and power up your machine. Your router should be at default now. Remember to reset you security, change the password, etc.
I have had to do this several times, sometimes unplugging the power, and plugging it back while holding the button. (Got 3 hand?)
Have you had a storm, or lightning issues lately? Sounds like it got a spike. Living the Florida, where lightning is very common, I have finally put my routers on a small UPS.
Good luck!

How can I extend my home internet network?

Yes you can connect the LAN ports with a network cable from your 3G router to one of your old router LAN ports
Before connecting the 2nd router:
Check it does not have a conflicting IP.
Check it is in the same subnet
ie if 3G router is
Set old router to
subnet mask
gateway is

Set DHCP off on 2nd router.
Set WIFI to Same SSID, same password and authentication
ensure it is on a different channel though.(not automatic on either)

Finally just to make sure remove any WAN settings from your router, any old ADSL config etc so that it doesnt think it is a gateway.

How to configure router & switch

You shouldn't have to configure anything except the PC's should have IP and gateway set to auto.

Here is how it works:

A router connects two separate networks and manage the traffic between them.

In most home network applications the router connects your local group of computers and devices known as the LAN with the Internet, commonly called the WAN or Wide Area Network.

The router usually assigns unique Local IP addresses to all of the devices connected to it via a service known as DHCP. The addresses assigned by your router are private addresses and are not routable across the Internet.

Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks. Computers that are connected to IP networks must be configured before they can communicate with other computers on the network. DHCP allows a computer to be configured automatically, eliminating the need for intervention by a network administrator. It also provides a central database for keeping track of computers that have been connected to the network. This prevents two computers from accidentally being configured with the same IP address.

Your cable or DSL modem will get a Public WAN IP address from your ISP's DHCP service. These public IP addresses are leased in blocks by your ISP and are Internet routeble. The modem is connected to the WAN port on your router. The router will manage the traffic between the devices on the LAN and the Internet.

If your 5 port switch is connected to one of the router's LAN ports and router's DHCP is on then it will configure the clients attached to It automatically.

How do i hook up my router?

There are several ways to do this, depending on how your network is configured.

Generally, if you have only one router - you connect the network jack of your cable modem or DSL modem to the WAN ("wide area network" or "internet") jack of the router with a CAT 5 network cable or jumper. Each computer's network jack would be connected to one of the router's (4) LAN ("local area network" or "home network") jacks labeled 1, 2, 3, & 4.

In the picture above, the left most jack (WAN) of the router connects to the cable or DSL modem. The "LAN" jacks labeled "1, 2, 3 & 4" connect to each computer's network jack in your home.

The above would change if you are simply adding this router to extend an existing network. You'd likely be using this router as a switch, and leaving the routing duties to the main router. Over simplified, all the CAT 5 network cables would be connected to the 4 LAN jacks. There would be no connection to the router's WAN jack because the output of the first router provides only private IP addresses used in YOUR location. The internet IP address from your ISP is used only at the first router so that your entire home has the single IP address. The WAN jack is for internet addresses only - and the LAN jacks are for local / private addresses in your home only.

Have a look at the LinkSys web site for help configuring your particular model router, or reply with the model and version here.

I hope this helps & good luck. Please rate my reply - thanks!

Wanting to make my laptop wireless connection


Connect the MODEM (device you received from your Internet Serivce Provider that gets the Internet signal) to the router via the WAN port. WAN stands for Wide Area Network and this gets you out to the Modem and then to the Internet.

Ports 1 and higher are for computers and network printers that you can directly connect to your LAN - Local Area Network.

To secure your connection, you will need to configure your router and you will need to connect your laptop to the router (either wireless or via one of the numbered ports on the back of the router), open a web browser and enter the IP address of the router.

Since you did not put the model of the router, I cannot give you specifics on how to secure the connection. You can go to the D-Link web site, find your router, download the manual and it will walk you thru the settings.

Basically, you will be entering a WEP key (a set of letters and numbers that you know) to allow only wireless computers that have this key.

If the wireless internet works, the desktop doesn't

Check that the cable-modem (or the DSL-modem) is connected to the 'WAN' port on the router -- there is only one 'WAN' port.

Check that one of the 4 (or 5?) 'LAN' ports on the router is connected to the network-adapter on your computer.

Turn the router off.
Turn the router on.
Restart your computer, and it should regain Internet access, for both "wired" and "wireless" devices.

Trying to hook up router. What is the wan for and the 4 inputs

The WAN port is the physical interface that provides input and output to and from the device that provides Wide Area Networking capability .. i.e. the modem that connects to your Internet Service Provider. The usual choices are a DSL modem, a cable modem or a Wired router or a wired switch.
The 4 other inputs are wired inputs and outputs for wired Local Area Network connections.
The WAN port normally connects to the Internet. It is not necessary to connect anything to the WAN port to have a network. But without one of the usual devices, you will not have access to the Internet.
The LAN ports connect to the network interface port on the individual computers that are part of the local network. One port connects to one computer.
A large system will have routers connected through the LAN ports to the WAN ports on sub routers and so forth.

I had a home network. Now, although the router recognizes an internet signal, the computer doesn't from the router. I still have internet, if I just use the modem. Can you help me get my home network back?...

Plug the ethernet cable from the modem into the Lan port on the router. Your modem and router are trying to use the same gateway ip address. If you know how to do it change the Lan IP address of the router and plug the modem back into the wan port and it should work..

Can I use 2WIRE 2701HG-B router in COX internet connection

No. A router has 2 main interface types WAN (for the internet connection side, and LAN (for the home network side) the 'LAN' side often has up to 4 ports and wireless connectivity for the home network.

The most common routers available at electronics retail use a CAT-5 connection for the WAN ports and the LAN ports. Your DSL modem/router uses a phone line input for it's WAN port, which uses a signal type that is incompatible with the cable modem output.

If COX doesn't offer a router with the cable modem package, you can go and purchase and common brand of home networking router, and attach it to the output of the cable modem.

The wan port is what you hook your modem to. Wan stands for Wide Area Network, which in your case is the internet. Your house with your 2 pc's and networking equipment would be considered a Lan, local area network.

The 4 ports on the router are switch ports, when you hook the modem up to the switch instead of the wan port the modem will only allow traffic from one physical, (MAC) address to pass through, this is why only one of your pc's can access the internet. The wan port on the router has its own MAC address, so the modem will associate with the wan port and trust all traffic that comes from that port.

Finally, after you have connected the modem to the wan port, pull the power cord on the modem then plug it back in to reset it, this will force the modem to orient with the wan port.
