I have been having a lot of trouble getting my computer to connect to the internetIt is only one computer on the network that consistently has problems. It was working ok recently, except that I would have to turn the router off and back on fairly often, because the computer would say that the DNS lookup failed. Today it stopped working, and now says that the adapter does not have a valid ip configuration. I do not know what to do.
I am having this problem on my acer intel core i3 laptop I think my Network adapter is corrupt I cannot connect to my Netgear(home) router anymore... I use to be able to troubleshoot/diagnose and fix the error but now it doesn't fix it anymore.Wireless works though...the problem only occurs when I plug a network cable into the NIC... I have tried other network cables and the router at work but it gives me the same error.things I have tried to fix NIC that did not work
cmd- iprelease/renew changing things in the registry changing mac address updating netgear firmware updating NIC driver uninstalling the bonjour service
I have tried putting the ip address...dns in manually?i am running on windows 7?
I can sign on with all tools (i.e. phone, PC, etc.), but for whatever reason, I am having issues connecting my laptop. I'm running Windows 7 on a newer laptop. I tried changing the password and it worked for a minute, but now that's not doing the trick. It keeps telling me it doesn't have a valid IP address.
I had just restarted my computer last night, and may have ended a process on the task manager that might have caused my internet to cease working and this error message to appear. Ive tried resetting the modem/router, resetting winsock and tcp ip whatnot in the command prompt?
i m not about to convinced what above are mentioned coz. i am having same problem (tried already above given tricks but noway to geting intenet access) is anbody there to reply from this tech center or simply this i called tech center without tech people..
So i got a new dell inspiron 5520 laptop running windows 7 home premium edition, and i set it up and began using it with no problems. however, recently when i have tried to use it i have been unable to connect to the internet, and my novice troubleshooting attempts produce an error message saying 'wireless network connection doesn't have a valid ip'.
Got randomly dc'd from my router today, tried reconnecting say that its an unidentified network and there's no internet connection; here's the IP config file

I'm studying for a Cisco certification and I'm trying to wrap my head around the routing. I understand how routers work for the most part and how the get updates about networks and how many hops away they are, but I don't get what happens when a router doesn't know the path to a network.
I have a desktop PC using Windows 7 Pro. and a Airlink N 150 Mini USB wireless adapter. My 2Wire modem/router from AT&T was failing to stay connected and was replaced today with a Netgear 7550 modem/router from AT&T. I installed the Netgear 7550 and am able to access the internet with my Asus Laptop, my LG Thrill phone, and my Samsung Galaxy 2 tablet with no problems. However, my Desktop cannot connect to the internet and the Window Network diagnostics returned the following message: Network Connection doesn't have a valid IP configuration. How do I go about connecting my desktop to the Netgear modem/router so that I have access to the internet? By the way I am able to connect to the internet using an ethernet cable and a LAN connection.

I have a new Windows 7 laptop which cannot connect to internet through my WRK54G Linksys router. Other laptops can connect through the same router, and the same laptop has connected through other routers. The laptop has it's TCP/IPv6 and TCP/IPv4 internet protocols set to get addresses automaticaly.
ipconfig shows that the IPv6 autoconfiguration address is 169.254.28.183 instead of 192.168.1.XXX. I tried the ipconfig/release and ipconfig/renew commands, as recommended by the knowledge base, but got the following error message: No operation can be performed on wireless network connection 2 while it has its media disconnected.
I have a Latitude D810. recently unable to get connection on wireless or wired. Lights are on on port plug.I can see the network, when I run troubleshooter on the Proset/Wireless Wifi Connection utility It says the wireless adaptor failed to get IP address and could be due to authentication failure with the network, incorrect wireless security passwords or because of DHCP server malfunction.I did the passwords, checked the router, all is ok there. My new computer works fine on this wireless network as well as my wired desktop. I suspect this happened as a result of a security change that windows XP or whatever security soft ware that's in there did, but cannot figure out how to undo or reset this.
error: "local area network doesn't have a valid ip configuration" Problem on another machine: aCER aSPIRE w/ windows 7 Had internet previously; no changes made to machine EXCEPT swapped hardware internet connection from Links router to a temp set up on a laptop.Couldn't get laptop to connect via hardware - went wireless instead Upon return of cable to ASPIRE, got above error message. Running connection Wizard doesn't do it!
I am using hp pressario C7000 with window 7 32 bits. Can not access the internet. The reports 'local area network doesn't have a valid ip configuration'.
partition the departmental IP network address block to create a staff and a student subnet. Each of these will be identified by its own network address and netmask. It is university policy that you must be economical with the IP addresses. That is, the subnets must be as small as possible, but they must be large enough to accommodate the maximum number of hosts you were given. Also, it is university policy that the respective gateway router to the outside world should always be given the highest possible host IP address in the subnet. The student subnet should have a higher IP network address than the staff subnet. The network must be able to support up to 60 machines on the staff subnet (not counting the router) and up to 120 machines on the student subnet (also not counting the router).
IP address/netmask University network address127.158.128.0 University network mask255.255.192.0 University internet gateway IP address127.158.191.254 Department network mask255.255.254.0 Department router address127.158.129.254
Suppose that the network address of the departmental network is 127.158.128.0 (calculated by AND between Dep network mask and Dep router address)I know that 60 machines would use 6 bits for the staff subnet.the netmask of staff would be 255.255.255.192.how can I figure out the the IP network address of the staff subnet.I have worked out the range for the staff subnetwork.
I have recently bought a Asus Eee PC with Windows 7 starter.It will connect ok to public Wifi (i.e. at the Qantas lounge) but will not connect to my home Wifi network - Netcomm N150 Router. The two other computer at home (running full versions of Windows 7) work fine over this network.When I look at the Station list in the Router's interface the MAC address for the new laptop appears but it has no IP address. [code] Have tried the obvious things like power cycling.
I have been facing the same problem with my wireless connection. I can connect to all the wireless connection except one, and it shows yellow exclamation mark in its icon.
A month ago my ISP was routing half my subnet (129-254) over DSL. I just moved and routing no longer works without NAT. The issue is probably with the new DSL 'modem,' a zhone 1611-A1, but I am not sure how it should be configured.The 1611 is connected to a WRT610N, which works in NAT mode with the following settings:[code] With the previous settings, networking doesn't work from a workstation, though I can traceroute from the 610. I would like all workstations on the "LAN" to have fully addressable internet addresses like the previous configuration.There is an admin interface on the 1611, but the cursory settings I've tried don't work and I'm not a routing expert. The ISP is kindly routing my network, but they don't provide much support.
I have 2 3560 switches that are running 12.2(25)SEE2. Port security is enabled on some of the ports. Whenever there is a power failure, when power is restored, 1 port on each switch goes to err-disabled. The mac address that causes this is a valid address for that port. Below is the configuration on one of the ports.
I have a dell laptop. It will pick up and connect to the neighbors wifi. But when trying to connect to mine it will not acquire a network address. It continuously searches but says 0.0.0... it says the signal is excellent but will just not acquire the ip address. By the way, cell phones with Wifi connect to this network with no problems.
So I want to watch some videos on justin.tv, but for some reason I have been IP blocked. I actually went on their support forums and the guy basically said "I picked up a bad IP address", so I didn't do anything wrong, I just got unlucky.
Keep a log of my own (Wan) IP-adress. It should look up my own IP-address and write it away to a log, so that I can look up a few weeks or months later what my IP-adress was on a certain day. I am using a router at home.
The last few days I had been getting the error that: "Local Area Connection doesn't have a valid IP configuration" whenever I reboot my computer. I have to power cycle the router before I can get back the internet connection. Checked on the web and tried various solutions which did not work. So I tried using various firmwares for the WRT160N V2 like V2.03 Build 7 and Build 9. Still did not work. Finally reverted back to my old and trusted FW2.02 Build 8. And this seemed to improve the situation. However, the error will still appear from time to time though not as frequently.
I am setting up a new E4200 modem, and have not been able to use the wired connection. The Windows 7 diagnositic on all three computers tells me "Local Area Connection, doesn't have a valid IP configuration."Model: E4200v1..I am using a new E4200 router, along with a new SE1500 5-port switch and a new SE2800 8-port switch.I am using a wired network that consists of two desktop computers, a laptop computer, a network printer, three Direct TV recorders, two Roku streaming video players, a BluRay player, and an XBox gaming console.Here is what I have done so far.
1- I can bypass the router to establish a direct wired connection to the cable modem. This works to access the internet. It establishes a new wired connection called Network 2. 2- I can access the internet using the wireless connection to the router. It shows a valid IPv4 address. 3- With all cables in place, all the lights are flashing on the router and on the computers. 4- I had changed cables and swapped cable ends. 5- Using the wireless connection, I can access the router home page (192.168.1.1). It shows valid IP addresses.
The problem is that my old Linksys BEFSR81 stopped working, with the same eror message for the LAN connection, "Local Area Connection, doesn't have a valid IP configuration."How often does the WAN port go bad? On both a five-year old BEFSR81, and a brand new E4200?
I'm working on a CCTV DVR which has network viewing function. The front controls on the DVR won't work at all so i am unable to access any menus or burn off the footage i need. I was hoping to connect to the unit via the network viewer software or web browser but i have no idea what the ip address is. Is there any way of finding out the ip address of the unit if i connect a pc to it via a cross over cable or through a switch or am i stuck because i dont know the ip range it is in?
How can know the Broadcast address before subnetting? I know how to calculate the broadcast address , but don't understand 'Broadcast address before subnetting'?
Is there any way to get an ip address through it's physical location? I was asked this by a friend and it's a good question. We know how to get the physical address by it's by coordinates, but is it possible to reverse it, getting the ip assigned to the physical address?
Am having an issue with my cisco 1841. I recently brought some IP Publics. Now that i need them i just can't use them, I don't know much about routers but till now have successfully manage to do some stuffs with the router after googling ,OK we already have some other ip publics and when i look at the config file i can see something like this:
i got a d-link router comming off modum and then a lynksys switch . well when i run the lorex program it (the switch) shows up as a router with a ip address ? i have tried a different swith but still the same thing happens .
