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)

  • 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.

  • 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.
    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 (No specific reason for 52, that 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. (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.

  • I need to Renew DHCP License every 90 seconds or internet freezes.

    I need to Renew DHCP License every 90 seconds or internet freezes. Do I need a new network interface card?

    IF using WiFi, hold the Option key and click on the WiFi Icon in the MenuBar to get a display like this one:
    What value for PHY mode?
    What Channel?
    What RSSI?
    What transmit Rate?
    How many other networks do you see?

  • 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.

  • 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?

  • 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.

    Urgent help. I have upgraded my phone but every few hours the apple appears and stays for 15 min an hour or more?

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.
    If the issue persists, take the device to Apple for evaluation.
