EA3500 dropping internet connection every 2 minutes

Hello!  I've recently purchased the EA3500 dual band wireless-N router to replace my old and somewhat tired WRT54GS.  The old router worked, I just decided to upgrade to wireless-N since all of my devices are now capable.
My ISP is Comcast and I use a Motorola SB 6120 cable modem.  
After an extremely easy setup of the new router last week, I experienced one full day of glorious speedier network and internet traffic.  However, roughly 24 hours after installation I started experiencing intermittetent internet connectivity issues.  As in - the cable modem is accessible for 2 minutes and then can't be found for 2 minutes, repeat forever.  
After multiple different troubleshooting steps, including rebooting both the modem and the router together, separately, and releasing and renewing the router's IP Address through the router's admin page, I finally ended up resetting the router back to factory defaults and letting Windows 7 guide me through the re-installation rather than using the provided "easy setup" CD from Cisco.
This seemed to have helped, but 2 days later, my "every 2 minutes" issue returned.  
Something important to note here is that all of my devices - both wired and wireless - are able to communicate with each other without issue.  For example - while I have no access to the cable modem, I am able to stream music from a wired desktop through a wireless laptop to a wireless receiver connected to my TV.  I am also able to access the router's admin tools during my connectivity issues.  
Has anyone here got some ideas for additional troubleshooting steps I can take?

There are many reasons why you experience poor signal or connection. Your slow throughput wireless connection has a relation to the kind of setup that you have in your home or office. Is the connection dropping on all wireless-N computers or just one?
Try to do the following steps:
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] Lower the MTU (Maximum Transmission Unit) from 1500 to 1492 or less (usually found on your routers main/ basic setup page)
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the username field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.

  • Loosing internet connection every 15 minutes

    I am "loosing" my internet connection every 15 minutes. The cable box was replaced. Internet sharing is off. The firewall is on and no ports are checked. But, every 15 minutes, I get a message (using Safari) that there is no connection. I select network diagnostics and after I go through a few steps, all the buttons are green and then the connection works. This is very problematic, though, since I am loosing work while working online. Any suggestions?

    Hi otobinchicago,
    The fact is you can delete the .plist (com.apple.networkConfig.plist) and re-enter your setting and you will find out if this is the problem, but as I can assure you I have been through the same process. Reconfiguring the computer, the modem, etc, and it was the hardware.
    You could try taking your computer to a friends house linking it to their modem and testing it that way. As long as the post-computer to ISP link is nothing to do with your hardware, you will see that it could be hardware or software.
    My bet is that it is hardware. It sounds too similar to what I had.

  • AEBS Dropping Internet Connection q 45 minutes

    I have the new airport extreme base station. I bought it January and it has worked flawlessly for the past 6 months. recently, in the past week or so, I began getting a dropped internet connection happening every 45 minutes or so.
    About my set up:
    Cable modem supplying connection to AEBS via ethernet. VOIP box connected to AEBS via ethernet getting internet connection from AEBS. Playstation 3 connected via ethernet to AEBS. Airport Express base station linked to airport extreme base station wirelessly (of course) to share printer connection via USB. iBook G4 1.2ghz running Mac OSX 10.4.9
    Trouble Shooting.
    Originally I would unplug the cable modem for 30 seconds and plug it back in. This would reset the connection and i would have service again for 45 minutes. I decided to test whether or not it was the router or modem that was kicking me so I unplugged the ethernet cable coming from the modem to the AEBS and plugged it directly into my computer and turned off my airport connection, essentially hardwiring the ibook directly to the modem. I got kicked off again. At this point i drew the conclusion that it was the modem and contacted my cable company. After a bunch phone conversations that essentially accomplished nothing, they sent a tech out to my house. He replaced my old (3 years) cable with a brand new one to test out. I left my computer wired directly via ethernet to the new modem and this time DID NOT receive any drops in connection over a period of 4 hours. I reconnected the ethernet cable from the modem to the AEBS and reset my connection and decided to test out wireless. It dropped me again in 45 minutes. I left the cable modem connected to the AEBS via ethernet and unplugged the ethernet cable coming out of the AEBS that gos to my VOIP box and plugged my computer into the AEBS via ethernet and disconnected from airport on my computer. I was again dropped in 45 minutes. I reset my modem and unplugged the ethernet cable coming out of AEBS that gos to my Playstation 3. Again I was dropped within 45 minutes. After that, I reconnected both the PS3 and VOIP box ethernet cables and unplugged my computers ethernet cable from the AEBS and have just been using the wireless connection and resetting the modem every 45 minutes when it drops. Oh yeah and I forgot to mention that I plugged the Playstation 3 directly into the cable modem via ethernet and played online for 4 hours without interruption/disconnect. Anyways, I am back to square one. I believe based on the evidence above that the problem lies within the Airport Extreme base station router some how, but I have no idea what the problem is.
    What happens when my connection is dropped:
    I can be doing anything from using an instant messaging service to trying to load a web page using firefox or safari. Basically the page fails to load, i get a message saying it can't find the server. Usually at this point I will open up network utility and try to ping yahoo.com. It doesn't ping and says it can't find the server. I go to the modem and unplug the power for 30 seconds and replug it back in. As soon as everything back up I have my connection back.
    What the cable company did:
    They looked at their connections, including the fiber optic node for the area. They did not find any outages or problems within their system. They plugged my coxial cable into a modem/tester box (not sure exactly what it was) to evaluate signal received via coxial cable which they said was working properly. they checked my cable connection from house to street and didn't find any compromises in the wire/cable.
    I have downloaded and installed the latest firmware for my AEBS. I am out of ideas. Can anyone help?
    ibook G4 Mac OS X (10.4.3)
    ibook G4   Mac OS X (10.4.3)  

    I had the same problem earlier this year with my cable carrier. At first I thought it was the modem so I replaced the Dlink with an Apple Extreme and it still kept happening. After some research on MacInTouch I found that using an earlier version of the base station software made the problem go away. So I never updated and all was well with the world. Till last week and now like you I am dropping connections every hour or so no matter what application I am running or what site I am on the internet.
    A friendly tech admitted to me that there was a problem with the way the modem communicates with the provider and that they were aware of the problem but that there was nothing he could do to help me.
    That is when I cured the problem temporarily by using the base station software from 2004. If I find an answer to the return of the problem I will post it. Please let me know if you find a solution.

  • Apple TV dropping WiFi connection every two minutes

    Hey there,
    So I bought an Apple TV a couple days ago. Product looks great and looks absolutely gorgeous on the TV I have. My only problem (and its a HUGE problem) is that the device drops my WiFi every two minutes. Specifically when watching videos.
    So in effect I cant stream any video - be it from YouTube, iTunes, NFL, Vimeo or even over AirPlay - because every time I do the signal drops and I'm thrown back to the main screen.
    My WiFi pretty good. I have an iPhone, an iPad, two PC laptops and a Samsung smart phone that use the same network without any issues.
    Please help me with this problem. I really really like the product but its practically useless with this issue.

    Other devices working doesn't rule out a network issue.
    Try connecting Apple TV via ethernet
    Go to istumbler, netstumbler or similar to get a network report. Look for signal strength, noise, and nearby networks.

  • HT1595 Apple TV loses complete internet connection every 5 minutes.  Tried restarting.  Tried unplugging the router, unplugging the modem, and unplugging Apple TV and it still does't work.  Get error message 22 saying it can't connect when I put in my pas

    It only connects for minutes at a time.  I have not changed my router, modem, or placement of my apple tv, modem, or router.  It just suddenly stopped working.  Any suggestions?

    Mine is doing the exact same problem!
    Ever since I rented a movie from itunes with the ATV connected to the internet via wireless (strong signal) from an airport extreme connected to my modem from charter communications (with about 30Mbps speed) it will suddenly stop and by stop I mean it leaves the movie completely and says YOUR APPLE TV IS NOT CONNECTED TO THE INTERNET.
    So if I go to my network in the apple tv menu, sure enough my wireless network is missing. But the ipad is finding it, and the imac on wireless is finding it, and it is working. So we hit restart on the apple tv. When it comes back all is good. Then maybe the movie runs ten minutes and it does it again.
    In some cases the wireless network reappears but if I select it it still says I'm not connected to the internet.
    I have to restart everytime or it will not properly reconnect to the internet or find my wireless net work and actually work and connect.
    It has been connected in the same place for a year and never had an issue.
    Nothing has changed..... I have not added a wall to cause interference....
    My iPad and iPhone show FULL strength.
    Please help!

  • BT Homehub 2 dropping connection every few minutes

    Hi, my homehubs been working perfectly until today when it started dropping the connection every few minutes (ranging from 3 minutes up to 13). The broadband and phone lights go out then orange and then back to blue after about a minute.
    Having browsed the forums etc Ive changed the location of the hub, changed channels, checked cabling and changed the microfilter.
    Im now at a bit of a loss. The firmware is Version 8.1.H.J (Type A) and i notice that the firmware updated on todays date.
    Im hoping someone has some ideas as im all out now.

    I have the same problem friday afternoon at 4.30 to 11.30 at night the router reset itself every five minutes ....the prob first started in nov 2010 i have had 3 home engineer visits and finally we might be getting somwhere it looks like its caused by interferance on the line the phones fine its the broadband ,looking at the engineers meter it was running fine then all of a sudden it spikes erros 21,000 of them the router reboots and steadys again .......somthings causing line interferance it could be anything a pir on a security light ,a street lamp with a faulty timer ,there has even been a case where a car tyre garage has had its broadband removed by sombodys faulty tv .......
             the engineer fitted a resistor box under the wall socket and ran the wires through it to the socket ...this is disigned to filter out certain frequencies of line pollution but not all ......it seems to be working its only shut down twice tonight and that could be the exchange mucking about as they are continuing to monitor the problem ......HOPING ....... oh he also removed the front of the wall socket and fitted me a dsl one with a separate phone socket hence doing away with the dsl filter ......................

  • Anyone having trouble with IMac dropping internet connections? inter

    My IMac is dropping my internet connection?
    Any ideas or suggestions on what is causing this?
    george

    I too have this problem but I've had it for about 2 years.  We used to think it was because I was on wi-fi and I was getting interference.  I moved the modem closer and that didn't help.  Then my ISP kept telling me it was my Dlink modem so I chucked that modem out and went with my ISP's modem.  That didn't solve the problem but at least my ISP couldn't blame it on other equipment.   I then moved the modem right beside my iMac and I was still loosing the connection  while on wi-fi.  I got so fed up that I have hard wired my iMac right into the modem and it's still happening.  Ive had my cable company out here a zillion times trying to trouble shoot this.  They changed all of my cabling from the road to my house and from my house to the computer.  They gave me a new modem and then they gave me another new modem but a different brand.  I'm still dropping my internet connection every few minutes. 
    The one thing that I discovered with my provider is that I'm not actually loosing connection to the internet as they don't see my internet dropping at all.  It's as if the signal comes and goes on this iMac and when it goes, I'm left with my curser doing the whirley-bird until it reconnects to the net.  Usually takes 5 minutes or so but it eventually comes back.  My wi-fi is fine with my iPad and my iPhone but it wasn't with this iMac.  I've been on Leopard, Snow Leopard and Lion and I've had the same problem with all three OS's on this iMac. 
    I'm totally at a loss as to why this is happening.  It's very frustraging and makes it near impossible to use online banking or booking flights etc because I can't keep a connection long enough.
    Anybody have any brilliant suggestions to try?

  • I just bought a new pc and My laptop can connect to it but my airport utility won't recognize it. Even though it does connect to the internet about every 15 minutes the internet shuts off.

    I just bought a new pc and for our internet connection we have an airport express. My laptop can connect to it but my airport utility won't recognize it. Even though it does connect to the internet about every 15 minutes the internet shuts off. What should I do?

    If you've not yet tried, unpower the AppleTV for a minute or so and restart - this occasionally corrects issues.
    If not and the software update seems to have caused an issue, go to the Settings menu and choose to Restore it (this will erase all settings) to reapply current firmware.
    Alternatively try to do so via iTunes:

  • Extreme Base Station suddenly dropping internet connection

    I have an Extreme Base Station (802.11n Fast Ethernet) which has been providing wireless internet and printing to two imacs pretty flawlessly for several years. It seems to be a fairly simple network. DSL modem (to WAN port) and USB printer cable plugged into back of Base Station.
    Several days ago, the Base Station began dropping connection to the internet every few minutes. If I connect the modem directly into the computer, I have no problems with losing connection. So, I began looking for solutions online and have been trying everything I could find to do. I've scoured the forums here, and everywhere and read a bazillion posts.
    I've done a hard reset of the Base Station, I've tried different channels, I've unplugged, waited ten minutes, and replugged in a myriad of sequences, including unplugging both the modem (Zhone/Paradyne 6381-A3) and Base Station overnight. The only thing I haven't done is roll back the firmware (currently 7.4.2 I believe). I'm still experiencing the same problems and am at my wits end. I've spent hours now trying to fix it and need to do other things like shop for groceries and vacuum! So, I'm posting, in hopes someone might be able to point me in a more productive direction.
    Is it possible the Base Station hardware is failing? What are the signs and symptoms? I hate to spend another $179 and still have the same problems.
    Thank you.
    Most kindly,

    Dear Bluenova - ( +or other interested readers+ )
    I know that this reply is two months since this topic was initially posted.
    This is a longstanding Airport Extreme ( AEBS ) problem that's been noted since 2006-2007.
    It has been an ongoing issue for me -AND- I continue to experience it even after recently upgrading my AEBS.
    I finally called AppleCare in mid-Sept. and opened a formal problem case report.
    As of today (Oct 15, 2010) I still have an open & unresolved case with AppleCare.
    The problem has been escalated twice -and- is now referred to Engineering Dept for research & resolution.
    I was curious what steps or actions you have taken -and/or- if you still experience the problem.
    _Readers Please Note_
    Many users have posted messages regarding problems with Airport Extreme *+DROPPING CONNECTIONS+* .
    However, with careful reading, it becomes obvious that many forum posters are not sufficiently clear
    -and- often confuse or do NOT make the distinction between ..... DIFFERENT TYPES OF CONNECTION PROBLEMS.

  • Problem with Dropped Internet Connections on AE/Macbook

    I have a dual band Airport Extreme connected to Comcast Cable. I use a first generation Macbook to access the airport. The problem is that I keep on getting dropped Internet connections. The signal strength is shown at the top rhs of the screen as being full strength (4 bars).
    If I swap out the router for a Linksys WRT54G, running DD-WRT, the combination works perfectly without any dropped Internet connections. Also, If I connect the Linksys to the AE with the Linksys acting as a wireless client repeating the signal, then I can connect the Macbook to the Linksys again without any dropped internet connections.
    There is something about the Macbook connecting directly to the AE. It happens intemittantly but probably multiple times a day and is very inconvenient. The only way to get it back is to reboot the router or stop/start the aiport on the Macbook.
    I have tried just about every possible setup on the AE including splitting the 2.4 and 5Ghz radios into two separate ssid's and changing the channels. I am using the latest AE firmware. I have also taken the AE back to the Apple store and they have swapped it for a new one.
    I dont get the same issues with my windows clients or my ipad (although i have experienced issues while steaming video - but I think that may be a different issue).
    Any suggestions/advice would be greatly appreciated.

    Use the advice in this thread to investigate the signal and noise levels that the Mac sees:
    http://discussions.apple.com/thread.jspa?threadID=2347845&start=1
    What you may see if an increase in noise when the connection drops.
    If that doesn't show anything useful, it might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
    1) Use the AirPort menu bar item to turn AirPort off, then on again.
    2) Try to select your Wi-Fi network from the AirPort menu.
    3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
    4) In the same panel as (3), define a new location and see if you can make that work.
    5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease".  Note that the fix this step implements may be temporary.
    6) In the folder /Library/Preferences ( _not_ <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
    These steps may not help, but they'll only take a couple of minutes to try.  Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them.  If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

  • WRVS4400N Drops Internet Connectivity with PORT SCAN

    I just installed a WRVS440N router and it appears that every time a PORT SCAN happens, the router just shuts down and drops Internet Connectivity for about a minute or two, then once the PORT SCAN is done everything seems back to nomal?
    I have heard many complaints about this router and wonder does anyone else have this issue?
    I also have very erratic Internet connections speeds and I turened off the IPS feature and that seems to help. I am running version 2.0.8 Firmware.
    If anybody has any tips or tricks to improve this router would like to hear. I can only say I regret buying this thing.

    I suggest you to play around with the wireless settings on the router, Like changing the wireless name , channel and the type of wireless security.
    This link will guide you;http://www6.nohold.net/Cisco2/ukp.aspx?pid=80&vw=1&articleid=3698 
    Also, you check the firmware of the router by going to the status tab on  the interface.
    Website you can check to download it.

  • My ipad mini loses Internet connection every time it automatically locks.

    My ipad mini loses Internet connection every time it automatically locks. I have to re-establish the connection but sometimes it would take too long for the Internet to be connected. I'm using a wireless connection

    just browsing around I found this question. Also on my mini retina I fight with this problem. After a lot of searching I found that the only solution is to switch to
    Airplane Mode, wait few seconds and switch again.
    Or, if you are lucky, to find a Genius who replaces your unit. Cheers
