Modem and router sharing IP address

Hi,  just stumbled upon you in a google search to reach d-link customer service...this is really cool!  hopefully you can help... i've had this problem a couple times before, but forgot how to fix it.  i just got a new computer, so i need to reconfigure my wireless set up so that the modem and router use different IP addresses.  i believe at the moment they are sharing the same, so that the wireless connection is dodgy and breaks after about 20 mins or so.   that said, it may break before i get your advice on how to fix problem.  but i'm hoping for the best. i'm using a MacBook Pro with a dsl speedstream modem and dlink router. thanks!! sarah

You will need to disconnect the modem from the router.

Then you will need to connect your computer to the router using an ethernet cable. (plugging into one of the LAN ports)

Next you need to log into the router control panel and change the IP address there. If your modem is giving out IP addresses like then you will need to change the 3rd octet on the router to an IP address like this:

Ip location

no. An IP address refers to an address that is attached to your network card (or your router). In most cases you will have what is considered a "Private" address (there is a range of addresses reserved for people to use in their private networks so that they don't get confused for things on the internet). So your computer will have a "private" address if you are behind a firewall, router, or internet service provider. You may be looking for your "public" address which would not allow someone to get to your computer from the internet, unless you had "port forwarding" set up in your router. Public addresses usually do not stick to your cable modem or dsl modem, and may change over time. If you need to figure out what your current Public IP address is you will want to go to google and type "what's my ip address" in the search, and it will show you (as well as some links to other web sites that will tell you what your IP address is). If you need to find your private IP address so that other computers on your private network can communicate with you, open the command prompt and type "ipconfg /all" and hit enter. This will give you a list of different adapters that you have on your computer, and what the IP Address is for each (you may have wireless, hard wired, even vpn adapters). The email address that is transmitted in the headers of your email is the public IP address of your mail server (or googles, or yahoos, or whatever your mail provider is).
Hope this helps.

If i turn my Thomson 585v7 modem off and back on it dosent change my ip and im sure i dont have a static ip

Depending on you ISP (Internet Service Provider) it may assign you a DHCP address with a certain amount lease time. in other words when your modem requests an IP to connect to the web your ISP says 'OK here use this one for this long'. When that time limit is reached it will request a new address at which point may then get a new one or it might just re-new the current one you have.

Typically your can log into your modems web interface and find a menu that will show the current status of your modem and somewhere on that page should be a release/renew button that you can click to force the modem to let go of its current IP address and request a new one. Again it might just give you the same address you just released back to you though.

Having the same IP address is not really a bad thing.

Hope that helps clear it up.

Iam having different ips from wan is this mean someone is accessing my network?

You just have Dynamic ip, nothing to worry about.

"Static IP addressing is for one customer on one IP address and Dynamic IP addressing assigns a different IP address each time the ISP customer logs on to their computer, but this is dependent upon the Internet Service Provider (ISP) because some ISP's only change the IP address as they deem it necessary.

If you have Dynamic IP Addressing through your Website Host it means that you are sharing an IP Address with several other customers.

If you are a beginner on the internet, an avid internet user, are entertaining the thought of starting your own website business, are a gamer, use VOIP or VPN there are several things you should know about IP Addressing."

No ip address

Many people need to connect additional computers or game consoles. To do this, most use a home network router, which shares a single IP address across multiple computers. No special configuration of your Shaw service or modem is required.

For information on how to configure a home network, consult the manufacturer's documentation included with the hub or router you have purchased.

  • Access the router configuration page.
  • Set the router to use Cable as Internet connection type.

How can i find my ip address to my arris tm602g modem

I would expect that unless you are a commercial account, your service provider assigns your IP dynamically. What that means is every time you cycle your router, you get a new address - though your "new" address may be the same as the "old" address, that is incidental to DHCP.

If you really want to know what it is at any given time, I recommend you get Network Magic from Cisco. As a matter of fact, you should probably get this software anyway. It is free to eval for 7 days and will assist in security issues, connectivity and sharing as well as many other things like finding out the IP addresses you seek. Read the deal while at the site. To find it, search "Network Magic" using your favorite search engine.

Recently I subscribed ATT DSL Service conflict IP Address

the motorola modem that att is using uses 192.168.1.x subnet. log onto your router and change it to 192.168.b.x where b is any number between 2 and 254 (just not 1). You should also log onto the modem and change the setting that allows it to share the external ip address with the router. You will need to do this if you plan on accessing your network from the internet.

Product 966, D-Link D524 Router.

It happens when you type wrong ip address and it automatically goes to google because google is the default search engine setted in your computer and the Ip address entered is wrong so it search for it and end up with some google search information

I hope you are not sure about your router Ip address - if you know how to find out the real ip address of the dlink router do it
and go to command prompt ping that ip address for reply.

Clarify me about your network structure - mostly default Ip address when you get it new is - Try to reconfigure it

Are you able to get a log page from the router
