Cannot renew IP address on some PCs, each day it's a different PC in my house. This started happening a couple weeks ago.

flush and renew your ip address via this commands:
*click the start menu*select "run"*type "cmd"*press enter*you will have a black screen*type ipconfig/release*then it will release your current ip address*type ipconfig/renew to renew the ip address then you're good to go.

The easiest way to release and renew your IP with a router that doesn't have that feature is to unplug the modem (not the router) for a few minutes - overnight while your sleeping to be sure.

Two possibilities:

1. the router is configured to hand-out IP-addresses in a limited range, e.g., 192.168.1.100 to 192.168.1.110, namely 11 different IP-addresses. When the 12th computer asks for an IP-address, there is none available. Remedy: configure the router to use a larger range of IP-addresses.

2. when an IP-address is handed-out, attached is a 'TTL' ("time to live") value, indicating how long the IP-address remains valid, e.g., 10 minutes or 100 minutes or 1 day or 1 week. If the TTL is too large, then each computer "hogs" the IP-address (even after being shut-off in mid-afternoon).
Remedy: configure the router to use a shorter TTL. Don't worry: when a TTL value drops to 50% of its original value, on a specific computer, the computer will "renew" the lease.

Did you try direct wiring the other pcs to see if they will connect separately? If they won't then check the network settings on each pc that won't connect. Make sure that the gateway address is the same ip address as the router is.

Did it work before the outage, all of them at once? If so go to the Command Prompt (RUN, type in cmd, enter and a small window will pop up), and where the cursor is blinking type in - ipconfig - (some win versions use winipcfg) , hit ENTER. That will tell you what address are set to. It should say 192.168.xxx.xxx.
Type in - ipconfig /release - ENTER. That will reset the addresses which should now all be zeros.
Now type in - ipconfig /renew - (make sure you have the blank space between the g and the /). This should give you the 192.168.xxx.xxx address for IP if your network settings are set correctly under Network Connections- Properties-TCP/IP

Sometimes under outages you need to reset both the modem, the router and the pcs to acquire the new addresses.

1. Release and renew your IP address
2. Click the Start menu button on the Windows taskbar.
   
   
3. Click Run... on this menu.
   
   
4. If the computer is holding a current IP address, type 'cmd' (without the quotes) in the text box that appears. A command prompt window appears on the screen.
   
   
5. Type 'ipconfig' (without the quotes) to view the status of the computer's IP address(es).
   
   
6. If the computer is holding a current IP address, type 'ipconfig /release' to let go of the address.
   
   
7. Type 'ipconfig /renew' to obtain a new IP address (whether or not the computer is holding a current address).

Tips:

1. If it is not necessary to view the current IP addresses on a computer, simply type 'ipconfig /release' or 'ipconfig /renew' (without the quotes) in the text box that appears in Step 3.
   
   
2. To bring a computer back onto the network after moving it to a different location, or experiencing an unexpected outage, first release, then renew the IP address. Computers on DHCP networks often (but not always) re-establish network connectivity automatically.

Also, make sure you are typing in the correct encryption key.

Your new isp probably has different dns addresses. Configure your dhcp to assign the new dns addresses. you can refresh the pcs by typing "ipconfig /renew" at the command prompt and your PCs will have the new dns addresses.
Hope that helps...

Here's what you can do Sometimes you can simply right-click the computer icon in the task bar near the clock of your XP desktop (If this icon is present). This will go through a process of resetting your IP address.
But if you do not have this option, you can go to START>RUN and type cmd. At the command line type ipconfig /release (or winipcfg /release in earlier versions of Windows). Then hit ENTER. Next, type ipconfig /renew and you should get a new IP address from the router.
If this doesn't work, renew the IP address. You will have to nullify the IP address on the PC, then shut the computer down. Next, unplug the cable modem for a couple of minutes, then plug it back in again. Once all of the modem lights are green, power up the PC again. It should automatically renew its IP at boot.
Unplug the router, then plug it back in AFTER you plug in the modem, but before you power up the PC. The router will need to supply the PC with a new IP address. Good luck, hope this helps or gives you something to try.

internet provider address. ring your provider and they will sort it

press F11 when turning on your PC

just right click on your local connection on the desktop by the clock and click on "repair". this should clear the cache and renew the IP addy and DNS for yur connection. OR
