Question

I networked my home computers through a Broadband router & DSL modem after a few days we loose network?

Answer 1

Okay, I've seen a lot of good posts except the"repinging the router??!" I've never heard of that.



Anyways, if the PCs are getting an IP ADDRESS (not 169.), open command prompt and type "ping yahoo.com" if you get four replies, great! If you get something else, like host unknown, that's a DNS issue and ensure you're passing the right DNS information from the router. Routers like to use their internal address, which doesn't work well sometimes. If you get reply timed out, then the issue is between your router and the ISP. So I would look at the router's external interface (wan, or whatever) and see if it has an ip address.



I am curious to know if its the PCs that are having the issue (dns or what not) or the router (losing the ip lease, etc)

Answer 2

one simple method.. to click run type cmd...( imean once u confirm all settings are correct but keeps droppin connections) on all coms and once a black screen appears, type ipconfig..



u can check the connections, the ip add and the subnetmask matches wat was on the router...



den if all matches, u could try to ping the router by typing "ping (ur ip add). all send and receive, den should be a pro..



or u could simply reset the ip address on the computers

IP addresses are unique numbers asssigned to every device on a network. They are automatially provided to your computers and devices by the HomePortal or OfficePortal using a network service known by the acronym DHCP. "Releasing" an IP address instructs the DHCP server that you are finished with the address and that it can be made available for other devices on the network. "Renewing" your IP address instructs the DHCP to either extend the time you are allowed to use your assigned address or to provide you an address if you don't already have one.



Normally, the process of releasing and renewing IP addresses is complely automated. However, in some instances, you may wish to refresh your IP address to troubleshoot a networking problem.



To release and renew your IP address on Windows 2000 and Windows XP:



Click on Start and select Run.

Type cmd and click OK.



When the black command screen opens (i.e. C:\>), type ipconfig /release. This will release your IP address. Once your address is released, you will temorarily lose network connectivity.



Once the adapter has released the IP address, type ipconfig /renew. This will request a new IP address. Within one minute your new IP address should appear. After renewing the IP address you should see an IP address of 172.16.x.x, 192.168.x.x, or 10.0.x.x. ("x" will be replaced by a number between 0 and 255.) If it shows an IP of 169.x.x.x then it is possible you are not physicially connected to the network. In this case, be sure that your computer's adapter is securely connected and any cables are securely connected.

Answer 3

if your networking workgroup is still set as MSHOME. then try changing it to something else

Answer 4

Repinging the router often helps. this allows the Router to reconnect to the proper DNS that your ISP gave you. Disabling or Unbinding Shares might help also.

Those arent porn sites, its Steve Gibson Research.

Its a little dated now, but it gives the basics of any network useing Windows.

It may just be the NetBEUI, but sounds like packet hopping, wich can also be NetBEUI related, microsoft will learn one day, but heck, they use Linux.

Answer 5

OK so you have the following.



Router

Modem



I am assuming that you are using your unit to share out the internet to your childrens computers.



"bought a US Robotics broadband router and networked my boys computers and mine to share the DSL connection"



Did you get a hub?



It would be better to use a hub in sharing your internet. Each unit is independent from each other. File sharing is where the problem starts.



Another thing you have to check is that your XP firewall protection might have just engaged. Cause sometimes it happens, its a flaw.

Answer 6

This problem may due to virus, kindly scan for virus if not found infected then try using the ping -t command from start > run and check the response.

Answer 7

did you run both wizzards at the same time and was evertying connected at the time and on?

Answer 8

restart

Answer 9

OK, since you have a router the individual computers shouldn't be going through any processes involving wizards or disks. The Windows XP Internet connection sharing is designed to try and share a broadband connection WITHOUT a router (and that type of connection often does conk out after a couple of days- it attempts to have other machines connect to the Internet through your computer, instead of connecting directly to the router)



All machines should have their TCP/IP settings as "obtain an IP address automatically" and "obtain DNS server automatically" - that's all. Your router will be the gateway but you don't need to specify that manually.



Anything else is probably creating more problems for you. I recommend deleting the existing network connection on the kids machine and let Windows XP create a default "Local area network" connection for you.



Did you previously have just one machine connected via the DSL modem, before you added a router? When the connection drops now, is your machine affected too, or just the kid's?



SBC/AT&T has recently been shipping some Speedstream DSL modems that work fine when connected directly to a computer but eventually drop the connection when routers are involved- what brand/model is your DSL modem?
