Can't connect to the Internet

I spoke to someone at Cox Cable and I was told to contact Motorola and tell them that Cox is a dhcp protocol. I was told by Cox Cable that Motorla need to reset my router. I was told to call 1-800-221-4380, however I am never able to get through or speak to someone becuse there is a recording saying to call back later everytime.

I also have Vonage phone service. If I unhook the router I loose my phone service.

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 to connect my Linksys router with my wi tribe modem?? my laptop pick up the wireless signal and can connect,,it says "connected" but when you open a page it says either "invalid server...

The Linksys Wireless router is fine, but your latop is not configured for DHCP (Dynamic Host Configuration Protocol). The computer is connected to the router at layer 2, whereas HTTP (Hypertext Transfer Protocol), sits
atop the TCP/IP (Transmission Control Protocol/Internet Protocol) layer, and seems to be trying to
query the ISP's (Internet Service Provider) network for a nameserver (via DNS (Dynamic Name Service) protocol) that doesn't exist on the ISP's network. Configuring the laptop for DHCP and specifying no nameserver will fix this (the ISP's network will dynamically assign a DNS).

Its also possible (though a remote possibility) that your Linksys wifi router may be configured to disallow TCP/IP virtual circuits to/from your computer's IP address - but this is a really advanced
capability of your Linksys wifi router - few know this capability even exists.

Connecting multiple wifi devices to the Linksys router should be no problem, just configure them all to interact with the router using DHCP.

If cox says it won't work on their system, there's nothing you can do to legally make that unit work. There may even be no physical way to make it work if it's simply using different frequencies or protocols than COX uses.
If you want cable internet from COX, you will have to call them and have them install it. Chances are they won't even charge you for the cable box, or it will be a very small monthly fee - and your internet usage will be on top of that.

Plz tell me if a laptop can connect to the internet using it's wireless connection if settings for the internet are used.and if it is poossible to use it,pliz tell me how! i'll be very greatfull. thanks

To connect a laptop to a wireless network for accessing have two ways

  1. DHCP (Dynamic Host Control Protocol)
  2. Manual entry of settings in wireless adapter properties.
In DHCP method you dont have to enter any settings on the wireless adapter. The wireless network which you are connecting will automatically assign an IP Address to you. But to use DHCP it must be supported by your wireless network.

2. Manual entry of settings in wireless adapter properties.

This method is mostly used over wireless Connection in small networks connecting 2-200 computers. In this method you have to obtain the following information from your connection provider.
  • IP address (Its format is "")
  • Default gateway address (very important)
  • Primary and secondary DNS (If not given then you can use "" as primary DNS and "" as Secondary DNS...thats free DNS service from google and its very fast)
  • Subnet Mask (not needed mostly...automatically generated)
To enter these settings you have to rightclick the Wireless Adapter>> and select properties>>Then double click the Internet Protocol version 4(TCP/IPv4) and enter these settings. In many cases when you are using proxy server then you have yo use proxy settings also in your browser..
Hope this will help....Cheers..:)

Cant connect my router to my new internet

Did the old internet come with the router? It may have static settings in it. If so, you will need to configure it with the new static settings, or at least put it on DHCP.

Make sure that your router and computer are set to get their IP addresses via DHCP.
Either the router is not setup as DHCP server or your computer has a static IP address assigned which conflicts with the router settings.
Do you have cable or DSL service (in which case the router should be set to PPPoE)?
If you have cable service, just reset the router to factory default by pressing the reset button on the back for about 30 seconds.

Then go to your computer and
  1. Go to Control Panel -> Network Connections.
  2. Right-click your Local Area Connection and choose Properties.
  3. Scroll down and double click on Internet Protocol (TCP/IP).
  4. Make sure that all settings are set to Obtain ...automatically.
Click OK two times (the second time takes a little bit longer, because the settings are applied.

If you have any more questions or need help with the settings, just come back here and leave a comment - I'm happy to help.

How do I set a new address in the 850 motorola router

First, you ned to login into your router (check the manuals for this, Netgear has this printed behind the router near Serial no. etc).
Enable DHCP settings, allocate IP-address range say to (enough for 5 computers connecting via this router). Next, configure each computer to accept new IP-address from router by enabling DHCP.
The settings on a Windows XP Professional Desktop:
Need administrator access to your desktop, right-click on Network icon, Internet Protocol TCP/IP Properties, click on Properties button, then select Advanced properties, you can set DHCP from here.
