Unable To Contact DHCP Server Wirelessly - Request Timed Out
Jul 3, 2011
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'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.

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 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]

Basically my friend has a game server with a particular IP. But lately I don't seem to be able to even 'see' that server. Pinging the IP gets a timeout. I did a tracert on the IP and from the first hop onwards it gives me 3 stars followed by a 'Request Timed Out' until the 30'th hop.

I first noticed it in games, and decided to ping my router in CMD. I see the occasional "request timed out", and not sure how to fix it.My other computers connected to the network are working fine, and I've tried USB Wireless adapters in my laptop which work fine, which implies the problem lies with the inbuilt adapter itself.I've tried reformatting, and updating drivers, but to no avail.I thought maybe the adapter might just be faulty, but then I decided to test it on Linux. I pinged the router in the terminal and... it seemed to work fine. I thought maybe some background process in Windows might be doing something to cause the problem, so I started in safe mode (with networking)... still the problem remained.

I have a strange issue where the first ping always times out, but the following goes through fine.I have Cisco877 and connection to the internet is fine. I connect a PC to one of the Fast Ether ports and I am able to ping the router without any issues. However, the moment I ping an external website [URL], the first ping request fails. after that the following request come through quickly.

I have a Cisco 1801 Router, but whenever there is anything plugged into the integrated 8 port switch for example two computers, I cannot get them to ping each other. All of the ports are on the same vLAN.
I am a Cisco newbie, so sorry if this question/query is really basic. Is there anyway I can test the integrated switch to see if it is faulty.

i am having a very wierd problem with my current internet connection , Its wired and while accessing websites seems just fine .. Accessing ANY program on the PC that requires internet does not work .. Examples of those can be steam/origin/any messenger/skype/teamviewer/teamspeak and the list goes on.. They all act like i dont even have an internet connection. I tried pinging in CMD by using Ping Google and i always get a request timed out .. I have also tried tracert Google and after the three * * * Its always a request timed out as well.. I have no idea whats causing and its pretty annoying as i mainly use the internet for skype and steam, Also on a side not this is not a problem with my laptop as i tried connecting to some random unprotected network that was near me and it worked fine

I have a E2000 router/access point. I am able to connect 3 laptops, 1 smartphone and 1 printer wirelessly to the access point. All computers and smartphone can access the Internet. The problem is that none of the devices can connect with each other and thus cannot print. I can ping the router, no problem. Get "request timed out" message when trying to ping from one device to the other. Router firmware is 1.04

Can your wireless router do a ping test to 66.161.11.90 [URL] or any other [URL] for that matter?Mine can't, either with my wireless PB G4 running OS X 10.4 or wired Dell running Windows XP. I tried it with a wrt54g v5 & wrt54g v6 both tests got a 'request timed out' with 100% packet loss. v5 had the latest firmware, v6 is still at 1.00.9

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 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.

I have an ASA 5505 with software version 8.2(1). It is making DHCP requests for IPSec clients that connect to the ASA. The DHCP requests packets the ASA makes have an extra '00' appended to the hostname field, and the length field is the size of the hostname + 1. The DHCP server is Microsoft Server 2003 and this causes the hostname to be registered with an unknown character which appears as []hostname. Then when server 2003 tries to update the DNS record, it fails because of the invalid character in the hostname. Is there anyway to have the ASA have the correct length for the hostname field in the DHCP packet, or a workaround that will solve this problem?

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.
