Can't access internet-unable to contact DHCP server?

Help! i'm a total computer flunkie so please not too much computer jargon-my husband accidentally cut our phone line which cut out our DSL and when he respliced it the internet started working on our builtin wireless laptop but not on our desktop that is using the WRT54G wireless router and compact Wireless G USB adapter.  None of our computers are near our phone line.  I tried to renew IPconfig through CMD screen but it gives me this error: uable to contact your DHCP server. Request has timed out.  I tried reinstalling the adapter but that didn't work.  Do I need to change something on the router by connecting our laptop to it? Please help!! This is driving me crazy Thanks!

Go to your device manager (Right click My Computer, then click Properties, then device manager should be under hardware tab), check and make sure your wireless adapter driver is installed well.
Then access to your router's web management page, ensure that the DHCP setting is set correctly. Might try to reboot your router after that. Finally try to acquire the IP address from your desktop computer again.
You can also try to assign the IP, netmask, gateway, DNS manually on the desktop computer if still failing to get the IP from DHCP server.
Hope helps..

  • X3000 Router - Unable to contact DHCP Server

    I have been experiencing this problem for about a week or two...
    Every couple of hours all of my computers and devices on the network lose their network connectivity and no matter what you do on the pc, nothing works...
    But as soon as you restart the router... everything works fine again...
    I have reset the router configuration, re-loaded the firmware and even changed the dhcp settings and the problem persists...
    Anyone have a solution?

    I would like to ask few questions, before I suggest you for any troubleshooting steps. Like- does it happen in both wired and wireless network? You can try the following combination of settings:-
    A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
              1] Open the software and go to the option which says "Router Settings"
              2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
             3] Then go to the Wireless tab, keep network mode as mixed, and make Channel Width to 20 MHz only and Channel to 6, 9, 11..
             4] Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page)
    B] If you haven't installed Cisco Connect then you can log on to the router's user interface using its default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the user name field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.
    Then check the connectivity status…

  • New Ipod Touch 5g can't access Internet in home network (using Linksys E4200 router). But, OK with other Wifi.

    Just bought new Ipod Touch 5g. I found out it can't access Internet in home network. not really cannot access, but very slow to open any web page, App Store failed to access, etc. But, OK with other Wifi (office & starbucks). Others existing iOS devices (Iphone4 & Ipad2) have no problem like this. I'm using Linksys E4200 router at home. anyone has any idea why?

    Try:
    - Reset the iPod. Nothing will be lost
    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on the router
    - Reset network settings: Settings>GeneralReset>Reset Network Settings

    - Restore from backup
    - Restore to factory settings/new iPod.

  • IPhone 5s can connect to wireless WIFI router but can not access internet.

    iPhone 5s can connect to wireless WIFI router but can not access internet at work. The admin says the router lets my iPhone connect to LAN, but the iPhone does not have server IP to access the internet. I entered the server IP and port number in the HTTP PROXY fields but I still can not access the web. Any ideas?
    TIA
    Rich

    You IT person should be able to sort this out.  But, they seems to be too busy or disinterested to do this.  Suggest you provide the it person with an iPhone to get interested.
    Any could be lots of things.
    The best you can do is to get access to the admin setup for networking on a pc?  The internet settings are all the same.  Only what names the manufactures change from OS to OS. Check and compare parameters.
    Phone works to internet at home, I assume?

  • Dropped connectivity - Unable to contact DHCP

    I have been dropping connectivity every hour or so. When I try to repair, it fails to reset IP because it is unable to contact DHCP. If I unplug the router for a minute, then it reconnects. I have three computers that connect to the router. 2 wireless, 1 ethernet. It seems to affect them all at the same time. It seems to be getting progressively worse, that is meant time to failure is getting shorter and shorter.
    The router is about 4 years old.
    Any suggestions?

    Forgot to say my router is a BEFW11S4 V2
    Thanks

  • I installed a new airport express and made it part of my existing home network...  now the PCs can't access internet through the airport extreme or the cisco access points

    Everything works perfect with Macs, iPhone, iPads but I have 2 pcs that now can't access internet. The PCs connect to the airport and my other access points but no internet- The PCs sent an error of DNS

    Yes, as we already said, it will do all of this if you have a good wireless signal reaching the bedroom.
    Remember that an extender or repeater or whatever you want to call it can only extend the quality of signal that it receives.
    The Ethernet signal that the Express delivers will only be as good as the quality of the wireless connection between the AirPort Extreme and AirPort Express.
    If you have doubts, make sure that you understand the store's return policy before you buy.

  • Weblogic 8.1 managed server unable to contact Admin server

    I have a strange issue here.
    I have admin server on Linux Machine A
    Managed server on Linux Machine B.
    When i try to start managed server on Machine B, i get the following error.
    The WebLogic Server did not start up properly.
    Exception raised: 'weblogic.management.configuration.ConfigurationException: [Configuration Management:150001]An error occurred while connecting to the admin server to bootstrap through URL: http://MachineA:7100/wl_management_internal2/Bootstrap, user: system
    java.io.EOFException
    at java.io.ObjectInputStream$BlockDataInputStream.readFully(ObjectInputStream.java:2571)
    at java.io.ObjectInputStream$GetFieldImpl.readFields(ObjectInputStream.java:1990)
    The error suggests that managed server on machine B, is unable to contact Admin server on Machine A.
    But i know for sure that Admin server is running on that port 7100 for sure.
    It has been for the last 3 years.
    To see if Machine B and Machine A have network issues, i did telnet.
    From Machine B: i typed the following
    telnet MachineA 7100
    Connected to MachineA.
    Escape character is '^]'
    The above telnet command tells us that no network issues exist.
    After a few tries, the managed server contacts to admin server and comes up.
    This is not a one time thing.
    I saw this behavior many times.
    How should i resolve this?
    Edited by: gvamsius on Feb 12, 2009 1:23 PM

    Every thing is configured fine.
    Nothing wrong with Configuration.
    This domain has been running for the past 3 years.
    Recently, i found something interesting in admin server logs, when i try to start the managed servers.
    I realized there will be some amount of hand shake that happens during managed server startup, when it tries to communicate with admin server.
    Here is the log snippet when managed server A contacts Admin server and starts up successfully.
    ####<Mar 10, 2009 12:11:42 PM EDT> <Info> <Configuration Management> <Admin Host> <admin-server> <ExecuteThread: '13' for queue: 'weblogic.kernel.Default'> <<WLS Kernel>> <> <BEA-150023> <Bootstrap servlet invoked with action isrunning from managed server Managed Server A.>

    Here is the log snippet when managed server B contacts Admin server and does not start.
    ####<Mar 10, 2009 12:07:07 PM EDT> <Info> <Configuration Management> <Admin Host> <admin-server> <ExecuteThread: '14' for queue: 'weblogic.kernel.Default'> <<WLS Kernel>> <> <BEA-150023> <Bootstrap servlet invoked with action isrunning from managed server Managed Server B.>
    ####<Mar 10, 2009 12:07:07 PM EDT> <Info> <Configuration Management> <Admin Host> <admin-server> <ExecuteThread: '14' for queue: 'weblogic.kernel.Default'> <<WLS Kernel>> <> <BEA-150030> <The bootstrap servlet has acknowledged that the admin server is running to the booting managed server Managed Server B.>
    ####<Mar 10, 2009 12:07:08 PM EDT> <Info> <Configuration Management> <Admin Host> <admin-server> <ExecuteThread: '14' for queue: 'weblogic.kernel.Default'> <<WLS Kernel>> <> <BEA-150023> <Bootstrap servlet invoked with action bootstrap from managed server Managed Server B.>
    The difference as you can see here is that managed server starts up only when Admin Server does the following
    <*The bootstrap servlet has finished sending the configuration to Managed Server A*.>
    Does any one knows why Admin server would not send the above bootstrap configuation all the times for the managed servers?

  • CUOM UNABLE TO CONTACT MAIL SERVER

    Hi everyone,
    I'm facing a problem when I declare SMTP server in CUOM "2.png"
    and if i try to send a mail I get a message "Unable to contact mail server" "1.png"
    Thanks

    I am having the same problem, only I am trying to update from 4.0.1 to 4.1
    It downloads fine, until the extracting of the file. That is where everything goes wrong. It can contact the server from Apple, but says it can not anymore when extracting the software. I cannot download the file solely and update the phone later. I really am expecting Apple to fix this as soon as possible. I paid over 600 euros for an official phone from Apple instead of conning them and buying a jailbreaked-one and now it does not work at all.

  • How do I fix "Unable to contact iMessage server. Try again." message?

    I am getting an "Unable to contact iMessage server. Try again." message on my iPad.  Anyone else?  Is there a fix or is the server just swamped.

    Is anyone at apple reading this. This has been happening since I updated my useless ipad to IOS 6 about a month ago. Apple breaks iMessage, FaceTime, safari and just about anything that has to do with sending pictures and all they do is remain silent. What kind of customer service is this? I loved my ipad until I updated to IOS 6. IOS has turned it into a piece of junk that just continues to frustrate me and obviously a lot of other people that just keep trying to get the apple applications to work when the problems are all on the apple server end. I will never spend another penny on an apple product after being treated like this. If this keeps up it won't take too long before the most valuable company in the world sees a crash in their stock price, and rightfully so. We need to talk to apple by selling our stock because once this gets out their stock will be worth about as much as my useless ipad.

  • IMessage "Verifying" then "Unable to Contact iMessage server"

    Just received the security patch ios 6.1.6 and installed. Now iMessage and Facetime are acting like I have never justed them.  iMessage wants me to log in, which I do. Then I click Next and it starts "verifying." After a long wait it states "Unable to contact iMessage server. Try again." Same thing happens with Facetime.  Why and how do I fix it?
