I'm having problems with two laptops. For some weird Both are acquiring the wrong DCHP, DNS and Gateway (server) address when I try to access the net via wireless access. For some reason, this does not happen when I use LAN (cable) connection.i.e. instead of fetching the address: 133.24.56.78 (not actual address), the system fetches/uses 111.22.33.44 (again, not actual address). BTW both systems are configured to fetch obtain IP and DCHP addresses automatically. I've tried to repair the connection in both cases, but it didn't work.What can I do to solve this problem?1 person got this answerI do too

If the wired and wireless pathways both access the same DHCP server (i.e., the same network), then it is wierd. If, however, the wired network is separate from the wireless network, they'll each have their own DHCP servers and so you'll get differnet addresses. This is no different than you connecting your PC at, say, your friend's house, and later, at a hotel. Different networks use different IP settings.Brian Tillman [MVP-Outlook]------------------------------If a reply helps, please vote it as helpful.

Both pathways access the same network/router. Yet I notice that the DCHP address the laptops try to use for the wireless interface is not the same as the one used for wired interface.

The first thing I have to ask is, Are you sure you are connecting to the correct wireless router? The other thing that comes to mind, is that maybe is beca use of 'wireless isolation' is set at the router. Though I can't say that I've seen a router do 'wireless isolation' that way. What are you using for awireless router? -z1p

HiAssuming that you are talking about regular Wireless connection of the 802.11a/b/g/n group, and Not some CellPhone type of Wireless Internet.While Wire connetion can connect diretly to a modem and obatin an external IP regular Wireless connects only to a local Networks.As a result the IP of Wireless computer is the 192.168.x.x type. Disclosing a local IP is not a security issue since it is Not accessible directly from the Internet and there are probably millions of people that use an IP like 192.168.1.1The number that you wrote out of fear, are not local subnets IP, thus there is No way to understand what Topology you are using and provide you with clear help.

I ran ipconfig /all on another laptop two different laptop with wireless and wired internet access. On both computers the address 192.168.1.254 was used as the Default Gateway, DNS server and DCHP server.However, on the computer that's unable to reach the wireless internet, the address 169.254.230.86 is listed as the Default gateway and Auto config IP address -- which is really weird considering that the system is configured to fetch obtain IP and DCHP addresses automatically. Ironically, the computer finds router has excellent signal strength but somehow manages to fetch the wrong Default Gateway address.

HiIt sees the signal but does not fetch anything.169.254.230.8 is the default IP thta Windows assigns when it can not make a real connetion with the Router.On 169.xx.xx.xx Part of a Wireless cable/DSL Router is a DHCP Server.The server assigns IP address to the Network computers that are configured to Auto Obtain IP address.If for some reason the computer cannot connect to the Router, it cannot obtain an IP and Windows assign a default IP 169.xxx.xxxx.xxx. This IP is Not functional IP for regular internet and network purpose.What to look for.There is an inherent Catch22 in trying to repair a Wireless computer through Wireless. Since the Wireless is not connected to the source, there is No interaction between the Wireless source and the Wireless Client, and no frame of reference to find what is working and what is Not working.As a first step, I will move temporarily the computer to a spot near the Wireless Router and connect it with a wire.When it works with a wire, switch Off the Wireless Security in the Router, disconnect the wire, and try to make the Wireless work. This should be done while the computer is still near the Wireless Router to compensate for weak, and or blocked signal that might be part of the problem in the further away working spot.In the computer itself.Most Laptops have a physical switch for the Wireless card. Read the computer's manual and make sure that the Wireless card is On.Check the Device Manager for valid Wireless card entry.http://www.ezlan.net/Win7/net_dm.jpgIf there is No valid entry, delete any Bogus Entry, and re-install the Wireless card's Drivers.Check the Network connections to make sure that you have a Wireless Network Connection Icon/Entry, and that the Properties of the Icon (right click on the Icon) are correctly configured with TCP/IPv4 protocol in the Network Connections Properties.http://www.ezlan.net/Win7/net_connection_tcp.jpgMake sure that if there is a vendor's Wireless Utility the utility is Not Running together with the Windows native Wireless utility.Make sure that No Firewall is preventing/blocking the Wireless components to get to the Network.If everything above is OK and it is not connecting to the Wireless router. Log from any computer that is, or can be connected to Wireless Router with a Wire, disable the Wireless Security, make sure that the Wireless broadcast is On, and try to connect with No Wireless security.When working turn On the Wireless security.Note* People sometimes make mistakes in writing and retyping the security passphrase.Alternative way is to copy it from the Router's menu, and then paste when asked by the Wireless card.-----------------------------------------I did every an I am still Block from connection to the Router.Software Firewall application that is Not configured to allow local traffic (between the computer and the Router is a possible issue too.some 3rd party Software Firewalls keep blocking aspects of Local Traffic even it they are turned Off (disabled). If possible configure the Firewall correctly, or totally uninstall it to allow clean flow of local network traffic. If the 3rd party software is uninstalled or disables, make sure that Windows native Firewall is On.Jack-MVP Windows Networking. WWW.EZLAN.NET

I think the others here have given you some good answers but here is my advice.1. Make sure you are connecting to the right network.2. Check the settings of your router; make sure the wireless is on PS you could also type a static ip address as an alternative configuration. This may enable you to get on the internet but it ignores the problem you are currently having.

I've tried disabling the laptop's firewall and also making the wireless network unsecure but neither worked.I've also tried manual configuration/assigning a static IP to the machine but it didn't work.This really wierd.

Hello, After going through steps you have followed from above suggestions, I would like you to try few steps.Open My Network places, View all network connections. Right click on the Wireless adapter and select properties. Now go to Wireless Networks tab. And now remove all the wireless networks present there. Now disable your Wireless adapter & restart your machine. After logging in to your machine enable Wireless Adapter and search for wireless networks. Let me know whats the result.ThanksDineshRegards Dinesh

OK Just to reiterate1.) You right clicked the wireless icon in the notification area (on the taskbar next to the clock). Then you picked "show available wireless networks".2.) You picked the correct network, then clicked the connect button.3.) It says you are connected but you can't get on the internet You could paste or type the results of ipconfig /all here?

Also, the laptop is able to see the router but cannot connect to it. What happens when you do steps 1 and 2 above. How do you know the laptop can see the router? How many networks do you see? Do you see yours and your neighbors etc?

When DHCP is unable to get an ip address it "gives up" and picks a random ip address starting with 169.254.x.x. I believe that when windows sees that you have an ip address of 169.x.x.x it realizes that DHCP has failed and displays "limited or no connectivity".My first belief is that your router is not giving you an ip address. That is because routers usually have ip addresses of 192.168.x.x with a subnet mask of 255.255.255.0 or something like that.http://www.techspot.com/guides/287-default-router-ip-addresses/If your subnet mask is 255.255.0.0 and the routers subnet mask is 255.255.255.0 then your laptop will not see the router.Also, your IP address should be similar to the routers ip address. So if the routers ip address is 192.168.0.1 then yours should be 192.168.0.2 or similar.Maybe your router is not set up correctly? If could be it is not giving out ip addresses to wireless clients. ----- Here is another "work around":Plug your laptop into the router with a network cable. Make sure you have internet access. Open up google or another website to verify that you can get on the internet.then go to a command prompt and do ipconfig /allWrite down all the settings for the ethernet card "local area connection".Write down ip address, subnet mask, default gateway, dns1 and dns1Open up the properties for your wireless card, select tcp/ip and select properties.Type in the stuff you wrote down.

To take care of you latest problem "unable to find certificate...", seethis other thread .Back to square one -- "limited or no connectivity" :(I'm sorry I didn't have a look at this. The thing that I've posted asked you to do the same.Please follow the steps suggested by RichKM.That gives very clear picture of the scenario. And are you able to ping the router frmo your laptop when its saying limited connectivity?ThanksDineshRegards Dinesh

I have to disagree here. Setting a static IP address on the wireless connection will most likely not be useful. The laptop not getting an IP assigned even though it is seeing the WLAN is likely to be caused by a configuration issue that is preventing the laptop from successfully connecting to WLAN. This issue will most likely still exist even with a static IP.A static IP would fix it, if the dhcp server in the router is turned off. Also, a static IP was tried previously according to this thread.Is it possible that MAC filters are enabled at the router? This would cause this type of issue.

If you run ipconfig release and then ipconfig renewfrom the command line what do you get for errors?

If you run ipconfig release and then ipconfig renew from the command line what do you get for errors?After running ipconfig /renew , I get the error message:No operation can be performed on wireless network /local area connection while it has media disconnected.BTW, someone has just come in with a MAC (we hate those, right ;) ) and she too is unable to connect to the wireless network. Time to call the ISP or change router, I think.

Problem solved.I changed the router encryption changed to WEP (from WPA-PSK).

Awesome!Its hard to troubleshoot security issues sometimes. Good job.If I helped let me know!
