Automatic Assignment of Network Address?

Question

I have broadband internet at home, so everytime I plug the wire in to my computer, it automatically connects.
But yesterday, while I was browsing on the internet, the connection failed, stating I have limited or no connectivity.
I checked different wires - it wasn't the problem. It can't be my service provider because there are other people in my house who share the internet and there's worked fine. So the problem is with my computer.
When trying to repair the connection, it gave the error that my network didn't assign a network address to the computer. Can anyone tell me how this could have occured, and how I can solve this?
Thanks

Answer 1

It means your computer was unable to obtain an IP address - this is done by a router (which is probably located somewhere in your building- ask the manager) If you've scanned your computer to make sure it's not become the victim of a virus or spyware that's screwed up the Internet access, the router's built-in DHCP server has probably crashed. Have them locate the router, unplug it for a few seconds then plug it back in.

It's fairly common for the DHCP server on routers to crash/hang so they stop giving out addresses, but still allow traffic to pass through. When this happens, computers that have been on for awhile and already have IP addresses continue to work normally, but if you reboot them they'll be unable to get an address as well.
So I'll bet your neighbors whose computers work fine now, won't be fine if they had to restart them.

I have to reboot my Linksys router about once every couple of months to correct this same problem. Others have to do it once every few weeks.

I have broadband and wireless, and this occasionally happens. In my case, it means a loose connection, usually the USB port. Are you plugged into the Ethernet connection, or are you using a USB port to plug your computer into the cable connection? Plugging and unplugging your connection can definitely cause this. Can you not leave your computer connected and click on IE when you want to log into the internet? This will solve part of your problem.

Windows network doesn't assign an address, your broadband connection does. You can call your cable/broadband supplier and get a technician to help if this continues. But first, check all connections. Sometimes you have to unplug the router for 10/15 seconds and plug it back in. This often stops it from knocking you off the internet.

I hope this helps!

ok by potential of community handle i'm going to assume you're talking TCP/IP. sure yet no longer in a properly designed community. i'm able to think of of two eventualities from memory that would reason this- a million. a community admin statically assigns an identical IP handle to 2 machines. this breaks arp tables and confuses the hell out of many centers. 2. the DHCP server fails or 2 DHCP servers are on line. it somewhat is extremely consumer-friendly in lots of small business enterprise networks that attempt to configure their first server. regularly your DHCP server would be a community server and be configured from that. Smaller networks purchase routers with DHCP already configured. whilst a shopper boots up it sends a revealed request that the two DHCP servers will answer (except it has an energetic registered hire and the shopper is conscious if it) If the DHCP (Server or router)a million has an identical scope as DHCP 2 you are able to duplicate ip handle. many cases the shopper machines will locate this out and tutor an errors. i'm hoping this facilitates.

Answer 4

Try unplugging your cable modem, wait about 10 seconds, then plug it back in. Sometimes this works for broadband connections.

Answer 5

You probably have a bad cable now. Try swapping out the cable to your computer (network cable) with another one.

Answer 6

Restrart that router thingy.
