I've been trying (in vain) to connect a USB Wireless device to be able to use it off my wireless network. I have (2) other laptops and (1) other desktop connecting to the router with no issues. For some reason, this old desktop keeps installing an Ethernet device (probably on the MB) and is automatically Configuring the IP address to that instead of the USB wireless device.I've tried uninstalling the Ethernet device but it comes right back after I do a reboot. Even when I disable it, I still can not connect with my Wireless device.
need to know why I can not connect to the internet after I am done downloading windows Xp on my Desk top. I got an error message from the cmd, saying that computer is unable to contact DHCP server.
I just moved to Auckland, NZ from the USA to go to school at the university here, and am having a problem connecting to the internet in the university residence hall in which I am living.Wifi is not available in the residence halls, so we need to use an Ethernet cable. When I plug in my computer, the network adapter icon says Identifying for a while then settles on Unidentified Network with no internet access, the IP is 169.x.x.x.When I try to release and renew the IP, it says unable to contact your DHCP server, request has timed out".I've tried multiple Ethernet cables, both brand new.I tried connecting to a port in a friend's room in the same building, and even in a classroom on campus, and both had the same result.Naturally after all that I assumed my NIC somehow died overnight while I traveled here, so I went to a computer repair shop expecting to have some hardware replaced, but we plugged it in there and it worked immediately so they weren't sure what to tell me.
I've gone through pages of old threads at this forum and others like it, trying solutions but having no luck.I've power cycled my computer, obviously I can't power cycle the whole network as it's for 200 people, but the IT people here have tried resetting it for me on their end as best they can.

I have a Dell 570 Inspiron desktop running win7 home premium w/ a 64 bit OS. I have Frontier dsl with a Westell 327W modem and a netgear router. Two desktops are connected to the internet...one through the modem and the Dell 570 through the router. I also run laptops through the router w/no problem. This morning the dsl went down, and when it came back up, the Dell 570 would not connect. i tried Diagnosing Connection Problems, and I'm told to turn off the modem/router (which I have done a gazillion times).When I look at Network Connections in the Control Panel, It tells me I have an unidentified network and can't connect. I read through some forums earlier, and found that releasing and renewing ipconfig often corrects the problem, and that's when I got the message that 'An error occurred while nenewing. Local Area Connection unable to contact DHCP server.' This set up has worked for the past year and a half. I looked at the network adapter, and it says it's working properly. I changed the cables going to the machines, and they both work on this computer. The only change made to the computer was to install McAfee security center through AOL yesterday, but the set up worked all yesterday and last night.
Until a couple of days ago I was able to connect to the internet wirelessly on both my laptop as well as my desktop. However, that has changed for the desktop, now I am unable to access the internet on it. It says that it can detect the signal. When I tried to renew the ip it responded with "An error occurred while renewing interface Wireless Network Connection : unable to contact your DHCP server. Request has timed out." [code]
I randomly lost Internet connection, and since have not been able to Renew an IP address! Other people in my household can connect just fine. I've tried numerous things to get my internet back, but continue to be unsuccessful in doing so.

I have reinstalled windows 7 on my Toshiba laptop, I have my wireless set to automatically connect, I have excellent signal strength and have another pc connected to wireless router, but my laptop does not capture IP addresses. I tried renew command but got message unabl to contact your DHCP server, request timmed out.
I've been having problems connecting my laptop to the internet through wireless. When I plug it in with a cable it works fine. I also know my wireless works fine because i have other things attached to it. When I try to connect it says limited or no connectivity, but the signal strength is excellent. I have tried to repair the problem but it then tells me it cannot renew my ip address. I've also tried the ipconfig /release then renew, and thats when it says about my DHCP.
I have a Gateway 818gm desktop pc and the wifi stopped working after I reformated the hard drive. I can not figure out where the wifi card is in this PC.
I can connect directly to the router wirelessly without any problems. When I use my powerline adapter I get the 'unable to contact DHCP Server' error. I've tried unencrypting the router with no success. I've also released/ renewed my IP. [code]

I am running a Dell Inspiron 530 with Windows XP SP 3. My computer is displaying cannot aquire network address, can't contact dhcp. I have already had the modem and ethernet cables tested, they're fine, and I have tried replacing the network card, no luck. I have also run ip config renew and replace as well as ipconfig/all everything was zero. I checked the startup menu and all the appropriate network apps are marked started and automatic.
I have a rather specific and annoying problem with my router. every few days or so the internet will cut out. However, i am still able to use websites that i have been using already, so am able to check emails read articles etc, but am unable to do things like stream videos from youtube or play online games. I run network diagnostics (Windows 7) and receive the error: Your computer appears to be correctly configured, but the device or resource (samsung.msn.com) is not responding. I have already updated all my drivers and have completely reinstalled my router and checked all cables etc. This appears to be only to do with computers that are connected wirelessly, as the pc connected via ethernet seems to be unaffected,
I have both a netbook and a gaming pc connected wirelessly. Netbook: OS Version: Microsoft Windows 7 Starter, Service Pack 1, 32 bit Processor: Intel(R) Atom(TM) CPU N550 @ 1.50GHz, x64 Family 6 Model 28 Stepping 10
I have a Time Warner modem/router. There are a ton of different devices constantly being connected/disconnected to our router - itouches, computers, smartphones etc.
The problem started with my otherwise super reliable HP g42 (i3) laptop. Nothing would solve the issue other than recovering it back a few days to when the issue wasn't happening. But then it would happen again after a few days. All other devices would connect without issue.
Time warner's technical troubleshooting consists of "unplug the router for 10 seconds and then plug it back in. Did that work?"
So now, my son gets his first computer and I bring it home last night. Also an HP (pavillion -i3). Same deal. At first, it connects fine and dandy. Then after about 2 hours it get the ol' "won't connect - diagnose the problem?" After diagnose, it says "DNS server may not be available.
Here's the thing: Both computers connect immediately and without issue to my smartphone wireless tether.
I can connect to the network but doesn't connect to the internet. I have tried a lot of ipconfig cmd's /renew said "unable to connect to dhcp server" and others didnt work all out of ideas.
I have an 871 set up at home with 2 VLANs, both of these vlans present a strange behavior where an user is unable to ping/contact another user on the same subnet, however if users are on different subnet it seems to work [code]
According to the troubleshooting that I have done, the issue seems to be with the broadcast traffic, ARP request/reply do not reach another host on the same subnet (wireless to wireless or wired to wireless) however if the wireless device iniciates the connection to wired, it works fine.
I have tried to enable proxy arp on the different VLANs and BVI and different combinations but no sucess in order to get traffic across 2 wireless devices on the same subnet or a connection that is iniciated for a wired client to a wireless one.
I tried enabling and disabling dot11 arp-cache but no luck.
Running ACS 5.1 appliance, and am seeing slow repsonse on TACACS authentications due to the ACS trying to reach overseas AD servers and failing. Is there any way to configure a /etc/host/ file locally on the ACS in order to force the appliance to use specific AD servers for authentication? As I understand the process currently, the ACS appliance will query the top-level domain and get a list of all the AD servers in DNS. In my case, this would include the AD servers overseas that we do not want to use.
We have 2mbps leased line and have Cisco 1841 which is managed by our ISP. I have hooked up another 1841 (please find basic config below, it will get more complex lateron) Now when I connect my laptop I am able to browse Internet. But when I conect VOIP phone, it is not able to contact it's Hosted Server on Internet.
VOIP phone is Polycom SoundPoint 550 and I get URL call disabed message. If I try netgear Firewall everything seems to work.that the voip provider needs following ports UDP Range 16384 - 32766, TCP 5060 & UDP 5060. But in my config all outbound traffic is allowed. [code]
I am able to obtain IP addresses through the DHCP server for my clients and I am able to browse internet on the server 2k8.Server 2008 - Share Internet through DHCP server
I purchased the EA6500 a few days ago, and when I'm connected to Cisco Connect Cloud I am unable to select Folder Access / FTP Server / Media Server. I click them and nothing happens.Also, the Cisco light on the router keeps blinking.
anyways here is my concern, we have a DHCP server in our company (HOTEL) and the Computer wont turn on, the computer is Compact Proliant Intel Inside Pentium Pro Processor OS Windows Server 2003, this Computer is so old. they been using this for 12 yrs and they didn't upgrade... now its dead.
since this Computer wont turn on, all of the computers cannot access in the internet, so for the meantime this is what I did... from the modem to router, I configure the router as a STATIC IP and I enter the IP address provided by our Internet Service Provider after that all of the computers form the hotel have internet connection.
now I'm planning to build a new PC and set up a DHCP server but I don't know how and where to start
