Re: ip address conflicts

Make sure that you are not connected both wirelessly and wired to one of the pc's, dissable the wired ethernet cards on all of the pc's as this may be the problem, and check in the DHCP client list in your router, refresh the list if you are able and see if there are two references to one pc with the same ip address. 


assuming you have DHCP enabled on the router this should not happen as long as your wireless adapters are set to obtain an ip address automatically.

I am trying to connect my Dlink DKT-401 router to my Linksys cable gateway router. I am not getting internet access when connecting to the Dlink network

1. Connect as local device or bridge - If connecting the second router via Ethernet cable, plug it into one of the LAN ports on the first router. If connecting the second router wirelessly, ensure the second router is set for client mode. Note that some home wireless routers do not support client mode; these must be connected by cable. Check your router documentation for details on its client mode configuration support.

2. Check / change IP address - Most home network routers use a default IP address setting. Often, these default IP addresses will not work in a two router environment. Check the second router's IP address value and reset it if necessary to work within the valid address range of the first router (and to not conflict with any other device on the network).

3. Disable DHCP - To avoid IP address conflicts between all of the devices on the home network, only one of your two routers should assign addresses via DHCP. All mainstream routers provide an option to disable DHCP as part of the router's configuration screens.

Instead of adding a second wired router to an existing network, consider adding a network switch instead. A switch accomplishes the same goal of extending the size of a network, but it does not require any IP address or DHCP configuration, greatly simplifying configuration.

My IP address on my wireless router does not match the one displayed on my wireless device (iPhone). The phone connects to the wifi network, but does not perform at the expected wifi speed.

The IP addresses should be different from each other, otherwise you would experience an IP conflict. Each device on your network (including the router) should have its own IP address.

We have a Linksys G Router. It works fine on my son's (Host) computer. My work laptop will recognize the wireless network but will not connect. My home desktop will not recognize the network. What are we...

There are wireless networking capabilities of the gateway that will prevent or allow specific MAC Addresses from connecting to the network. Go into the wireless settings and adjust the settings to accept the MAC address from your work computer. To find the MAC address from your computers network adapter go into a command prompt by typing cmd in the run box and typing "IPconfig /all" in the window. The MAC address is there it may be called Physical Address. It is always a 16 set of number and letter combinations divided by ":" between every 2 sets of number / letters. On your home desktop this same window will help you diagnose the problem. Your son's computer will help you with this, do this on his as well and compare the IP address with your home computer the address could be something like "192.168.1.?" the last number is going to be unique if the first three numbers match. If the IP address on your home computer doesn't match the first three octets "192.168.1" it will not get out through the gateway. If they don't match you can force it to be on the same network by setting up a static IP address by opening up the Control Panel / Networking icon and finding the icon for the network adapter that you are using and opening it up and clicking on "Properties" and clicking on IPv4 and clicking properties and clicking on Specify IP address and typing the first three octets of your son's computer and adding a fourth number that isn't "0" or "255". You can use any number between those two numbers except those numbers, and isn't the same as your son's IP Address or the Default Gateway which is the Linksys. The "Subnet Mask" will auto install but will be "". The default gateway and DNS server will be the IP address of the Linksys which most likely will be "". Click "Ok" on all the open dialog boxes and the computer should be able to get on the internet.

Identify the peripheral conflicting with the router and change the network address on one of the two. Their setup programs should give you the possibility to do so. The address should look like: 192.168.2.x
x ranging from 0 to 9

You may have an IP conflict. Renew the IP on both the Sonys
At a command prompt,
ipconfig /release
it will come back with all zeros

ipconfig /renew
It should pick up a new IP address.

Intermittent Connectivity:
NOTE: Before following the steps in this article, check if your wireless computers have stable connection when connected to other wireless networks (hotspots).
This article assumes that all wireless computers are experiencing intermittent wireless connection with the router.
Frequent wireless disconnection can be caused by different factors such as:
  1. Wireless interference within the network.
  2. Wireless settings of the router are still set to default.
  3. Firmware is corrupted.
Reducing Wireless Interference
If you are experiencing frequent disconnection from the wireless network, it helps if you check the following factors, all of which can greatly affect your wireless signals:
your cordless telephone system (or even your neighbors’), or other nearby equipment. Try to change your router’s channel to 1 or 11 (the default channel is 6) and restart the wireless computers.
Physical obstructions: Your router or wireless computers may be losing connectivity because of physical obstacles such as walls and floors. Try to move the equipment to different locations to find a better link.

  • Placement of the router: place your router as high off the ground as possible. When placing the router in a high location, leave a distance of two feet between the router antenna tips, ceiling, and wall. If your signal passes through multiple floors, place the router on the upper-most floor, and high up in the room.
  • Surroundings: Keep the router away from large metal objects, bodies of water (fish tanks, bathrooms), and any electrical equipment including television sets, microwaves, radios, etc.
Customizing Wireless Settings of the Router
Having default wireless settings on the router may cause conflict with other routers within your network range. Recommend changing the SSID (network name) and the Wireless Channel of your router. Also, if it is possible, enable the Wireless Security of your router.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Can only connect 1 computer to router

You might need to check if your laptop is able to get a valid IP address when connected wirelessly to the router. You can go to the Control Panel then click on network connections and look for wireless network connection. Right click the wireless network connection then click properties. Click the support tab and there you will see the IP address. You should not be getting 169.254.x.x. Where X represents numbers.

An IP address is very important. Make sure you're getting a correct IP address and it should be the IP address provided by your router. Without a valid IP address, you won't be able to get onlinwe. Your wireless connection can tell you that its connected eventhough its not getting a valid IP address.

Loosing connection frequently

Your computer has an IP addy and your router has its own IP addy. Try uninstalling the router and its software, reboot, and reinstall everything, this may clear up the conflict. If not you will have to go into the router(via the internet) and reconfigure the router.
