Need to renew dhcp lease often

to use the internet (wireless network) i must renew the dhcp lease every time i click a link or open a window. ive reset internet preferences and removed filesharing software. any ideas?

I also have the same problem and it started off small and it took me much trial and error to discover that only by renewing the DHCP lease every time I wanted to open a page could I still surf the net. My internet service provider first suggested that I try rebooting everything and I did -that worked for 5 minutes...then it was back to square one...I spoke with apple they were surprised that it was happening and gave me the option of paying for an over the phone trouble shooting diagnostic explaining that it could be the network card. For some reason last night everything worked perfectly without having to renew the lease.. and then this morning I am once again having to renew with every page. I did try an IP program called IPNETMonitorX but was quickly confused/overwhelmed with tech babble...
Has anyone solved similar issues?

  • Needing to Renew DHCP Lease every five minutes to stay online

    I experienced ALL the networking and DNS problems since my Leopard install, but adding OpenDNS servers to my router cured the problem. For two months, anyway. Now, in the last week, I've got problems again, and now the only thing that cures the suddenly dead network connection is to simply Renew DHCP Lease. Instantly my connection works again. But I'm needing to do this LITERALLY every five or ten minutes. Once I do this, it returns me the same IP address (as my router is set to do so), and all works again. Monitoring outbound network activity, I can see continuous failed requests to resolver1.openDNS.com and resolver2.openDNS.com. Barring waiting until 10.5.2, which we all hope resolves these problems (hur hur), any ideas?

    I have had wireless problems intermittently for a year, and seriously for 6 weeks. Apple denied the issue and was no help in spite of many tens of thousands of people on their own discussions complaining. I found a post suggesting a couple of things which fixed the problem. I don't know if both are necessary, but the first by itself does not solve the problem.
    Lock the channel of your router to channel 1, apparently Apple and 802.11n don't play well together on higher channels. When this becomes a standard this will be resolved I hope.
    Open your network preferences, select 'airport' and advanced. Delete unused networks. Select your network.
    Open TCP/IP and write down all the settings, configure iPv4 manually. Enter the settings manually. Turn off IpV6.
    Open DNS and write down your DNS server. Delete it and re-enter it manually.
    This has worked on 2 macbooks and an iMac for the last 3 weeks with no network drops.

  • Continually have to renew DHCP lease

    Occasionally my MBP will loose wireless connection. It often happens when my phone accesses the wireless Linksys router.
    Every time it happens, I open network preferences, go to Advanced and "Renew DHCP Lease" and it fixes it.
    Almost looks like I could use a script or something to make it renew DHCP lease when wireless disconnects.
    Any ideas?

    Usually not a problem with your Mac.

    I really appreciate you being one of the few trying to help. My negative comments come from my frustration at Apple.

  • Self-assigned IP after trying to renew DHCP lease for former network

    Hi all,
    MacBook Pro 15" purchased in Februrary 2008, currently running 10.5.5, up-to-date with patches as of yesterday, 10/20/2008.
    For a few weeks now, I've been consistently unable to connect to wireless networks (secured or unsecured, public or private) after changing networks (i.e. going from home to a coffee shop).
    I have control over my home network router, and its logs show that upon connecting to the network, OS X tries to renew a DHCP lease for the previous network it was on. Upon receiving the "bad network" DHCP reply, instead of releasing the lease and obtaining a new one, the AirPort interface is immediately assigned an IPV4LL address (from 169.254.0.0/16) and no combination of changing network settings, changing AirPort settings, or rebooting will eliminate the old DHCP lease.
    The end result is that my MBP is entirely nonfunctional on some wireless networks that other clients (both Windows and Mac) seem to have no trouble accessing. The problem is quite annoying because I can't connect to access points that (previously) worked fine and whose configurations haven't changed.
    In any case where this problem occurs, an old DHCP lease for a different network (10.0.0.0/8 when trying to get on 192.168.0.0/24 or vice versa) is present, so I strongly suspect a DHCP problem. In all cases, I have perfect connectivity to the access point itself, so problems with the wireless connection parameters (including encryption), or those troublesome problems with 802.11b/g/n interoperation seem highly unlikely.
    One of two things would help me:
    1) Please tell me how to clear the DHCP lease cache. Deleting files from /var/db/dhcpclient/leases does nothing (they appear again upon reboot, identical save for timestamps even after changing network environments, so the cache must be read at boot time and written at shutdown). Selecting "Renew DHCP lease" from the "TCP/IP" tab in the advanced network settings merely attempts to renew the existing lease (for an invalid IP address); it does not appear to release invalid leases.
    2) If this is really how the DHCP client is behaving, change the DHCP client so that upon receiving the "Bad network" response, it releases (or simply abandons) the lease and obtains a new one, rather than immediately assigning an IPV4LL address to the AirPort interface.
    Additionally, is there any documentation on the Apple DHCP client? Under Linux, I could alter dhcpcd parameters to diagnose things like this. I could find no documentation about the Apple DHCP client outside of Mac Help, which wasn't really any help in this case.
    Finally, I do not suspect that this is an instance of the problem discussed in http://discussions.apple.com/thread.jspa?threadID=1352518&tstart=0 as my connection is rock-solid if it can get an IP address when it connects. I've never even seen it hiccup.
    Thanks,
    Matt Z.

  • Can not connect with dhcp - renew dhcp lease will switch directly to manuel

    If have the following problem
    I us apple Airport extreme to connect to internet.
    I have 5 Macs, all connecting with airport . They work fine with DHCP. Since 2 weeks I have a problem that one computer – a mac book pro with 10.5.6 will not connect.
    When I switch to dhcp and select renew dhcp lease it switch directly back to manuell. I have no chance to connect with dhcp.
    Has anyone a suggestion?
    Thanks

    Wonder why Apple hasn't chimed in on this one...
    Whenever you have an issue like this where it's fine, then DHCP stops working for any reason.... Reset the PRAM.
    How to:
    Apple Logo -> Restart.
    After the screen goes black -> Hold down all 4 keys until you hear the third Bong.
    "Option"+[Apple Logo OR key to the left of the space bar]"P""R"
    After the third BONG or Apple Chime whatever you want to call it. The system's Parameter Ram or to the PC Crowd the CMOS has been reset. This resets your clock, brightness, volume, etc.... So things will get reset along the way but it also resets the IRQ and DMA stats on the logic board. Ala, reseting your Airport's Connection to the logic board, Controllers, etc.

  • I have to renew DHCP lease every few seconds to stay online

    I'm having trouble staying online. I can surf 2-3 pages, then it will not load the next page. I hit renew DHCP lease and the page will load but I am doing this every every 20 seconds. I spoke to my ISP (Time Warner) for almost an hour and could not solve it. They said everything was fine on their end and it sounds like a computer problem. I've used this computer and internet connection for over a year without ever renewing DHCP lease now I do it all the time. Any advice would help.

    I'm having the exact same problem. Sometime the pages will work for a while. Then the internet will start dropping out for a few days at time.
    I've reset and restarted everything, tried everything that I can think of. The only thing that seems to help is to renew the DHCP lease whenever it starts to happen. It will load one, maybe two, websites, and then the browser just says "connecting to (insert website here)"
    Please help, Next step is calling up AppleCare, which I would rather not do if I could. I'm a college student and i use my laptop to take notes during classes. (I type much faster than I can write)

  • Windows 7 does not wake from sleep to renew DHCP Lease

    I am having trouble with DHCP and sleeping Windows 7 systems.  My Windows 7 systems go to sleep after an hour or so.  The Intel and Broadcom NICs we have use ARP offloading so they continue to respond to ARP while the machine is sleeping. 
    The problem is that after the DHCP lease expires, the NIC continues to respond to the ARP requests and that causes IP conflicts on the network because the computer is responding to ARP requests for an IP address the computer has lost its lease on.  Any
    time a computer is asleep for longer than the DHCP lease time then when a new computer gets the IP from the lost lease, an IP conflict is reported because the new leasee does an ARP to see if the IP is in use and the sleeping computers NIC responds to the
    ARP and this results in an IP conflict for the new leasee.
    I opened a ticket with the Hardware Vendor, which is Dell in this case, and they opened an engineering case with Intel - the NIC OEM.  The outcome of this case what that this is Windows fault.  Windows is supposed to wake up from sleep and renew
    its DHCP lease at the lease half life and then go back to sleep.  My computers are not doing this.  They let the lease expire while they are sleeping.
    Is there a problem with Windows 7 that prevents it from waking up and renewing its lease periodically?  It is supposed to maintain the lease according to Dell and Intel, but in my case it it not. 

    Extending the lease time is a bandage on the problem, and it is what we have done while I attempt to resolve the issue.
    The network group would like the lease time set to 4 hours.
    Extending the lease time doesn't resolve the issue because it only makes the problem occur less freqently.  With a 2 week lease, a machine needs to be asleep for 2 weeks before it causes a problem.  Machines are not likely to be asleep for 2 weeks
    very often.
    The resolution would be to figure out why a sleeping Windows OS is not maintaining its IP address.  If it is not going to renew the DHCP lease while it is asleep, it is still responsible for updating the TCP stack (and the NIC) to let it know that it
    no longer has a lease to that IP address.  The OS has offloaded ARP to the NIC, which continues to respond to ARP while the computer is asleep.  If the OS lets the lease expire, then it needs to notify the NIC to stop responding to ARP requests for
    that address.

  • How do I fix that I constantly having to renew dhcp lease?

    I am constantly having to renew my dhcp lease.  Can anyone help resolve this issue?

    I was having this problem the other night after I finished doing a massive upgrade to our Home Network (New Router, Modem, Cabling, Etc)
    I  had to reset my DHCP lease every few minutes, in the end I found it was  the IP Address kept setting itself to other items on the Network, I  have some items coming through on wired (ethernet) and some were checking in on WiFi (Airport Extreme) the Mac Mini would grab an IP address that it thought was available and then we would have a clash.
    I was watching the items on my Routers Attached devices screen, The Mac  Mini would show up on the page with its new address (after hitting the  DHCP Renewal button) then something elese would check in with that  exisiting IP Address, clash and the Mac Mini would need the DHCP lease renewed again.
    I'll  be the first to admit my Networking knowledge is limited (and I'm learning more all the Time) but I simply went into the preferences panel and set the IP address manually.
    1. I went into preferences and selected Network
    2. Set Configure IPV4 to: using DHCP with manual address
    Now it helped I had my NetGear Routers "Attached devices" Page open here so I could see the address of everything else on my network (I went and  switched everything on that was web connected so it would be logged in  and running on the network) I looked at the last digit or 2 of every  item on my network and then set my new IP address.
    3.  To ensure I wouldn't have any more clashes I set my new IP address far away from the the others* your only changing the last digit or 2 of the  IP address, so in the case of my Mac Mini it went from xxx.xxx.02 to xxx.xxx.0.52 (note the x's are normally your IP address numbers)
    *I originally set it to xxx.xxx.09 but I since found the TV had that IP address (The one thing I forgot to check the previous night) so I this is when I decided to set it far away from the rest of the bunch by setting it to .52 (Note: 52 was just the 1st number to pop into my head)
    Now that was over a week ago and since then I have had no more issues on my  Network, so far everything is running smooth and fast.
    This is probably not the ideal way to fix this issue, but so far it is  working, hopefully someone with quality networking experience can chime  in with a more permanent solution.

  • I need to renew DHCP Licence every 20 minutes or so.  Any ideas?

    About once every few months, there is a span of a few days that I need to renew the DHCP Licence every 20 minutes or so to get onto the internet.  Then, everything works, but the DHCP error moves to another computer.  There are 5 computers at my work.  From the router, the signal goes into a gigabit switch, where it is piped into three different rooms.  In the room where we have the most problems, or we seem to as it's the main work room, the signal goes into another gigabit switch, which connects two computers and the Airport Extreme.  The DHCP error happens on the wired computers, a PowerMac G5 and a G4, and the Mac Book, connected to the Airport.  All the computers are running 10.4.11.
    Any ideas on how we can avoid this procedure every few months?  Thanks.

    Someone correct me if I'm wrong, it's been a while since I read about it, when a device connects using DHCP to a DHCP server it first asks if it can use the IP address it used previously and the DHCP server will reply yes or no (and supply a new Ip address).
    There are a number of areas where confusion can occur, if the device ignores the new IP address from the DHCP server, or if the server (incorrectly/ says yes when it should have said no, perhaps for the wrong reasons, ie. the IP address requested is outside the range set aside for DHCP allocation. A flaky DHCP server may do this.
    Has the configuration recently been altered ? New firmware for any of the routing devices, not just the AirPort. Or the configuration altered ?
    Or are there 2 DHCP servers, or 2 servers offering DHCP services ? This doesn't have to be an issue if the ranges do not overlap, but if they do you may see what you are experiencing.
    I changed my DHCP range allocation a few months ago to accomodate some new servers in the reserved range at the bottom end, so the servers could have static IP addresses (I'd only reserved 10 initially). What a nightmare with some of the DHCP Macs, most were fine that were up and running at the switch, but others that booted afterwards and those that booted into multiple OS's sometimes refused to initially pick up a new IP address from the correct range. A quick pull of the cable, to get a self-assigned IP and the put it back in seemed to work. AirPort attached devices were the hardest, my router STILL thinks my PBG4 is attached on two IP addresses (it's connected ONLY by AirPort, no Ethernet, etc), 192.168.0.12 and 192.168.0.24. 24 is the correct one but apparently there's a device called PowerBookG4.local on the .12 address. Everything works so I'll sort it at the next power-down of the networking kit in March.

  • MacBook Pro, Netcomm NB7Plus4W and Renewing DHCP Lease + Airport Express

    Problem 1 - Internet Connection Problem
    I am in a locatation with:
    2 x Late 2011 Macbook Pros 0sX 10.7.3
    1 X Mid 2010 Macbook Pro Osx 10.6.x
    3 x iPhone 4 iOs5.x
    1 x PC Windows XP
    ADSL2 internet connection
    Wireless Netcomm NB7Plus4W
    The 2 x Macbook Pro's 0sX 10.7.3 have difficuly connecting to the internet after wake from sleep, restart etc. They connect to the wireless network okay however they are very slow to get online, usually about 3-5 minutes minimum. Usually what is required is openening System Prefs / Network / and renewing the DHCP lease, which reduces the Internet connection time by a couple of minutes.
    Other devices connect okay.
    Problem 2 - Airport Express extending wirelss network
    I would like to add an airport express to the wireless network so music can be played through iTunes to a coneected sound system, however the instructions in Airport Express Help do not seem to work.
    Thanks for your replies in advance
    Christo

    I don't think it can be a Leopard-specific issue, or even a MacBook or Airport one, 'cause I've been having the exact same problem for several weeks on my old G4 tower running 10.4.11 & connected by ethernet to a NetGear router. :\ In all user accounts it opens a few web pages then loses connection until I renew the DHCP lease - strangely, this seems to happen quicker while using Safari than Firefox, but that could be coincidental. When the G4 has lost its connection, both my 3G iPhone and my boyfriend's POS Dell laptop have no trouble connecting wirelessly.
    I plan to try BDAqua's hardware test suggestion as soon as I have time to hunt for my Tiger install disks. Any other suggestions would be appreciated.

  • Renewing DHCP lease on a frequent basis....why?

    for some reason I keep losing my internet connection and I have to renew the DHCP lease in the network system preferences pane. why would I have to keep renewing this lease? I have no clue as to what this lease is but everytime I lose my internet connection I press this button and I have a connection again.
    I dont know what is going on to make me lose connection like this on an everdyday basis, several times a day in fact. any ideas? should I have time-warner swap out my modem?

    my apologies, I should have been more straightforward with the info.....
    once I move the desk/mac/modem is when I started having problems with outages. I noticed the problem, opened the network prefernces pane and tried the renew button. connection came right back for a while. went out again and again.....there is no consistent time limit on how long a connection stays up.. hit the button and its back....before I moved everything I never had this problem....

  • Does anyone else have to renew their DHCP Lease every 30 seconds when using the internet?

    Everytime I want to use the internet for surfing the web or browsing iTunes etc I have to go into System Preferences and navigate through to a button that says "Renew DHCP Lease". If watching catch-up TV online I have to click this button every 30 seconds or so because the programme freezes, and if I'm surfing the web or browsing iTunes I have to click it every time I want to update the content of the page. Does anybody know what my problem might be?

    This Fix has got things working for me.
    I have reprinted this response from another thread I have made (Repost) A number of people were asking me about my fix, so I have expanded my response to hopefully offer a little more clarity.
    I was having this problem the other night after I finished doing a massive upgrade to our Home Network (New Router, Modem, Cabling, Etc)
    I had to reset my DHCP lease every few minutes, in the end I found Mac Mini's IP Address kept setting itself to other items on the Network, I have some items connected on wired (ethernet) and some were connected on WiFi (Airport Extreme) after clicking the DHCP Lease Renew the Mac Mini would grab an IP address that it thought was available but then another item on my network would "check in" then we would have a clash, The Mac Mini was grabbing what it thought was an available IP address, the DHCP Renew button was not setting the Mac Mini's IP number far enough away to stop the clash.
    I was watching the items on my Routers Attached devices screen, The Mac Mini would show up on the page with its new address (after hitting the DHCP Renewal button) then something else would check in with that exisiting IP Address, clash and the Mac Mini would need it's DHCP lease renewed again.
    My Network consists of:
    - Mac Mini (Wired)
    - Acer Laptop (Wired)
    - PS3 (1) (wired)
    - Apple TV (wired)
    - Airport Extreme (wired and looking ater WiFi duties throughout the house)
    - PS3 (2) (WiFi)
    - TV (WiFi)
    - iPad (WiFi)
    - Nexus 7 (WiFi)
    - Printer (WiFi)
    I'll be the first to admit my Networking knowledge is limited (and I'm learning more all the Time) but I simply went into the preferences panel and set the IP address manually.

    Now that was over a week ago and since then I have had no more issues on my Network, so far everything is running smooth and fast. (It has now been over 3 weeks since I posted this, and everything is still working perfectly, I suggested this solution to 2 friends having the same issue and it also fixed there problems as well)
    I'm not saying this is the be all and end all to the problem, there must be a more permanent solution out there, but this is working for me so far.
