Wired BEFW11S4 frequently loses connection to internet. Fix?

Hi.  I use a BEFW11S4 router wired into my home computer.  There is also a wireless network connected to the internet through this router at my home.
I am having a strange and frequent problem of losing connection to the internet on my wired computer.  I'll often be searching through websites or playing a game when the internet connection drops.  I often have to reset my router to reestablish internect connection.
However, the strange thing is that when this happens, the wireless computers stay connected to the internet.  Without resetting the router, I can simply go to a wireless computer in my house and still browse the internet.  To me, this indicates that there is a specific problem going one between my wired computer and the router.
This is also distressing when I am playing games on my computer.  When I play games and connect with more than 2 other users on a game server, I very frequently get disconnected from the internet on the wired computer.  This never happens when I only play with only one other user.
I've tried hard resetting my router, deleting cookies, internet history, etc., and deleting everything in my temp folder.  However, the frequent internet disconnection on the wired computer remains.  Is there anything I could try doing to prevent this?

Well try upgrading the firmware of the router & keep on holding tightly
the reset button in such a way that power light is blinking on the
router & then do a complete network power cycle i.e., unplug the power
cables from the modem & from the router & then plug in the power cable
to the modem first once all the lights are solid green you could plug
in the power cable to the router & check out it will definately work!!

  • PLWK400 loses connection to internet

    Hello:
    I recently purchased and installed the Linksys PLWK400 Powerline AV Wireless Network Extender kit to my home Local Access Network (LAN). To access the internet, I use a Motorola SURFboard cable modem/wi-fi router (model #SBG6580). My Internet service (ISP) through DirecTV.
    The problem I am having is since I've installed the PLWK400 on my LAN, my wireless devices (laptops, smartphones, etc.) lose internet connectivity after a certain amount of time and I have to reboot (power cycle) my router to regain the connectivity. After I manually reboot my router I will regain internet connectivity for sometimes up to a day or so, but then I cannot connect to the internet again and will have to manually reboot the router again...which seems to clear the issue once again. 
    Sometimes, I will only have connectivity to the internet for just a few hours and will have to reboot the router again. This frequent loss of internet access did NOT happen before I installed the PLWK400 kit on my LAN. To rule out other problems, I have uninstalled the PLWK400 kit for up to a week with no internet loss issues on my connected devices. Once I reinstall the PLWK400 kit it starts happening again. It keeps happening no matter how I configure the PLE400 or PLW400 devices. I have tried to setup the PLWK400 kit using the default encryption and SSID it generates right out of the box and I've also tried assigning my own SSID and advanced encryption (where I assign an SSID and encryption type that matches my router's). Either way, my wireless devices ultimately lose connection to the internet. Again, this does NOT happen when the PLWK400 kit is NOT installed on my LAN. I believe the issue may be related to my router being on default DHCP settings and my ISP renewing it's assigned IP to my router (IP lease?) about every 24 hours or so. It seems like when this happens I lose internet connectivity while my PLWK400 is installed on the LAN. The only fiix seems to be a hard reboot of my router. Which again seems to fix the connectivity issue for about a day. 
    Additional information: I have made sure I am using the same assigned network key for both the PLE400 and the PLW400. Also...when I do lose internet connectivity I can still see the PLW400's SSID being broadcast when I perform a network scan. This tells me that the signal is still being sent from my wifi router through the PLE400 to the PLW400 and being emitted, but for some reason I cannot access the internet and am forced to have to reboot my router to gain internet connectivity. 
    Any advice or feedback you may have on what may be causing this problem would be appreciated. Or, any suggestions on how to fix it would be really appreciated. I've also tried assigning a static IP address to the PLW400 through it's online utility and also tried extending the IP lease time-frame to my devices on my router's internal settings. These actions have not worked. I still lose internet connectivity sometimes after a few hourse but mostly after about a day. I really enjoy the additional range of wi-fi in my home that the PLWK400 enables, but having to continually reboot my router to maintain connectivity to the internet is very inconvenient.

    Try giving the PLW400 different SSID's so no two are the same. This will allow for more detailed troubleshooting.
    Please remember to Kudo those that help you.

  • MacBook Air loses connection to internet but not LAN

    Hi, I am using a MacBook Air 11" (mid-2012) running OS X Mavericks (10.9.3). I'm connecting to my home LAN via WiFi connection to a TP-Link 300M Wireless router that is setup as a switch (per instructions here http://www.tp-link.com/en/article/?faqid=417), which in turn is connected via wire (ethernet-over-power) to a Technicolor cable modem/router provided by my ISP (UPC in the Netherlands; I can look up the model number of the router if needed, but it's two floors down right now and doesn't strike me that this is the cause of the problem).
    I have a problem that my MacBook Air intermittently loses connectivity to the internet for extended periods (minutes) even though (a) the MacBook Air maintains full connectivity to my LAN at the same time through WiFi and (b) other computers connected to the cable modem/router maintain their connection to the internet while my MacBook Air has lost its connection.
    My test to see where the breakdown is occurring is to have four terminal windows up and running ping processes:
    1) ping to 192.168.0.1 (my router) - this always stays live, with essentially no lost packets
    2) ping to an external address (I'm using 74.125.136.94, a google.nl address) - this is my main test for access to the internet and where I see ping failures (I'm also testing with pings to other sites when the problem is occurring to ensure it's not something on the remote end).
    3) ping to 192.168.0.13, which is a Synology NAS attached via ethernet cable to my main cable modem/router - this always stays live, with essentially no lost packets.
    4) a login to the Synology NAS, where I am also running a continual ping to 74.125.136.94, and this external ping does NOT fail when the one from my MacBook Air does, it stays live with essentially no lost packets.
    The problem will usually correct itself after 1-3 minutes (though the time is not consistent), and also gets corrected if I turn the MacBook Air's WiFi off and on again.
    Any suggestions for what I can do to stop this problem?
    Thanks

  • MBP C2D + Airport Express + WPA frequently loses connection. but WEP OK

    many people seem to have wireless connectivity problems with their MBP
    -- here is the problem I see with my 2wk old MBP and my wireless setup at home (Airport Express) and at work (Linksys, model# unknown):
    1) MBP C2D + Linksys + WEP = no problems
    2) MBP C2D + Airport Express + WEP = no problems
    3) MBP C2D + Airport Express + WPA = frequent dropped connection, and poor range
    for reference, my previous laptop:
    4) Pismo + Airport Express + WEP = no problems
    5) Pismo + Linksys + WEP = no problems
    with WPA (whether WPA or WPA2) and the MBP, I turn on Airport, signal looks strong, but then suddenly disappears. I have to toggle Airport off and on and then (sometimes) I'll successfully re-establish connection - only to possibly lose it again at some random point in time. Or it may work fine for an hour or more - it's hit or miss. no such problem or inconsistency with WEP enabled instead.
    both laptops are running OS X 10.4.8. Of course only 802.11b on the Pismo, but results don't change on the MBP whether b, mixed b/g or only g.
    The Airport Express is set up as a closed network, it's running firmware v6.3 (though I also reinstalled v6.1 but no change). I've tried many of the various other ideas for fixes - deleted Airport related keychains, etc played with various other Airport config settings - but all evidence points only to WPA as being the differentiating cause.
    does this match anyone else's experience?
    and more importantly, is there some fix?
    thanks in advance for your feedback or suggestions

    Hi!
    Used to have same problems. But not anymore.
    Here's what I did. I have a DLINK 624 router. not the same model but this could help you, I guess
    1) Disable Super G mode into router.
    2) Choose a 62 character key with a $ in front of it. (go https://www.grc.com/passwords.htm) and use wpa2.
    3) Uncheck the Robutesse Interference (sorry, i am french) in the airport menu.
    4) Change the advanced performance settings from auto to 11 (Tx rate) into router.
    5) Whent into keychains and only kept the one for the active wi-fi. Since I tried almost verything, there where a lot!
    Since I did that, no more lost connection for a day now!
    Now I am not saying that this is the ultimate fix....but It worked for me.
    BTW, did not do the SMC and EFI upgrade, still a little scared after what I read in the forums...I bought my mac book pro last week...how come it did not came with all the upgrade done??!! bizarre.
    Good luck!

  • Airport Extreme intermittently loses connection with Internet?

    I have an Airport Extreme connected to a router that is connected to our cable modem. Internet connection is fine, but the Airport Extreme will intermittently lose connection with the Internet and shows a solid amber light. Turning the Airport Extreme off and then on again will resolve the issue, however, this happens about once per week (at different days/times) and would like to ensure a consistent connection even when I'm not at home. (We are thinking of installing a lighting control system that depends upon a consistent wireless connection to work properly, even when we aren't home to restart the Airport Extreme). Please advise on what the trouble might be and how we can get a permanent resolution to the issue.

    Is your Extreme an 802.11g (domed-shape) or 802.11n (squarish) model? Do you have the Extreme connected to the other router by Ethernet? Finally, is the Extreme configured as a bridge, i.e., Connection Sharing = Off (Bridge Mode)?

  • Airport loses connection to Internet under heavy load

    Often, all the computers in my house will lose their Internet connection. However the network stays up just fine. There are both wired and wireless computers. A Netgear 16-port switch handles all the wired machines. The only solution is to pull the power cord from the AEBS and plug it back in. 30 seconds later, everyone's Internet is back up. The AEBS gets its Internet connection via PPoE to our DSL line.
    From recent experimentation, I've discovered that this happens a LOT more frequently (at worst, every few minutes) when there is a lot of Internet traffic - many short connections, like when I run web scraping bots. If we go on vacation for 2 weeks, the connection stays up fine.
    I know this problem has been discussed before but I've never seen a solution. All Macs and AEBS are on the latest software. Any suggestions?
    - Desperate for AEBS love

    I'm experiencing problems with airport connections recently, too. I did a lot of analysing since then.
    My configuration is based on a linux-driven NAS connected to two wireless acesspoints (1x SMC Barricade 2804WBR, 1x Fritzfon with recent firmwareupgrades). Two PowerBooks are connected with cable, two use their inbuild aiport cards.
    Volumes are mounted from teh NAS via NFS.
    Everything worked flawlessly for serveral month until, I assume, to the 10.4.8/10.3.9 update. I'm afraid the net isn't this much loaded that the connection losses were showing up immediately.
    But then there was the need to rebuild the iTunes biliothek on the MacBook Pro which uses WLAN (connected to the SMC). For some time the connection worked but then the connection to the server (NAS using NFS) was lost. I tried it with cable an without (10.3.9 and 10.4.8). The same problem occured.
    I tried to transfer different kind of files and folders an identified some files which seemed to cause the server losses. Always at the exact same point. But I had to learn that theses points differ whether I connect via the SMC or the Fritzfon. I have to say that the connection via the Fritzfon are somewhat more stable.
    Fact is, that if the problem occures the whole network stalls, not only the connection between WLAN accesspoint and the client computer but the connection between cable-connected ones, too.
    It's even possible that the server or the SMC becomes unresponsible via telnet so I have to restart it by pressing the reset-button.
    I think I'll roll the MacBook Pro back to 10.4.7 and do some extensive testing with only this one active in the net.

  • WRT610N Loses Connectivity To Internet Again and Again

    I recently purchased two WRT610N v1.0 wireless routers and connected to two different Teraon cable modems which are each connected to TimeWarner Cable.
    What I am finding on both of the WRT610N is that I am having to either Release & Renew the Internet (WAN) IP address or if that does not work, then reboot the routers. Testing of this involved using the PING and TRACEROUTE utlities on teh router to external IP addresses. After Releasing/Renewing the WAN IP addresses, the routers work for extended periods (e.g. 12-24 hours) and then again the routers stop talking to the cable modems.
    The WRT610N units replaced older D-Link routers which did not have this recurring problem. I have refreshed the v1.0 firmware on both WRT610N units (latest on Linksys web site) which did not seem to make any difference on the two routers' WAN (Internet) interfaces.
    Has anyone else seen this problem on the WRT610N or another router and have any thoughts as to fixing it since I do not like to have to get on the routers' http server as admin to release/renew the WAN (Internet) IP addresses and do not want to show newbies in case they mess with the other settings via the HTML interface.
    If there is a way to script this process (release/renew), that would work as an interim since I could set up an icon on the desktop for the newbies.
    Note that the problem has nothing to do with the wireless setup or the LAN side since I am using the PING and TRACEROUTE utilities from the router.

    I'm having the same exact issue with this model although Linksys is ignoring the fact that this problem exists. I have the WRT160N V2 model. I have 6 PC's on my network, four of them are running Windows XP and two are running Windows 7. All but one is wireless. ONLY the "Windows 7" PC's experience loss of connectivity to the internet but maintain network connectivity. It seems obvious to me that there is a Windows 7 compatibility issue but Linksys is in denial. I lose internet connectivity intermittently and have to reboot the router to get reconnected. Nothing else works. I thought this was an issue with just my router but I see here that I'm not alone. Perhaps Linksys should at least consider the possibility that there may be an issue with their product and try to resolve it instead of ignoring it in the hope that it will go away.
    I receive this message in the Windows event viewer:
    "Name resolution for the name wpad.hsd1.ca.comcast.net timed out after none of the configured DNS servers responded."
    And this message:
    "Name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded."
    IF ANYONE FINDS A SOLUTION, PLEASE POST IT. I"M THIS CLOSE TO TOSSING IT OUT THE WINDOW AND BUYING A BETTER BRAND!
    WAKE UP LINKSYS!

  • Apple TV loses connection to internet and can't reconnect without restart

    When I first purchased my ATV3 it had extremely slow buffering problems and then crashed. I had to do a full factory reset and software update. Then that problem went away. Recently it has a new problem. While renting a movie from itunes with the ATV connected to the internet via wireless (strong signal) from an airport extreme connected to my modem from cox 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.
    From time to time it finds it and when I select it it asked me to log back in with password etc. So I do that, and then it says some error code (sorry didn't write that one down) and says try again later.
    I have not tried hooking up my ethernet cable. Since my other devices all work while the apple tv is kicking me off, I don't believe it is a problem with our wireless network. And there are no buffering issues.
    Anyone heard of this ?
    Should I reset my factory settings? (I don't own the mini usb cable for the apple tv so connecting to a computer is not an immediate option)
    Any suggestions are welcome.
    Oh, and my original apple tv, the older model with the 160gb hard drive in it works fine. Just don't rent on it because of resolution of the older model.

    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.

    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.

  • Why does Airport Extreme frequently lose connection to ISP?

    Today my Airport Extreme purchased in March 2011 has lost connection to the internet 4 times.  I have had to reboot it each time to resume using the internet.  Does this indicate a problem with this new airport exteme.  If so do I return it to an Apple Store for repair or replacement?

    Today my Airport Extreme purchased in March 2011 has lost connection to the internet 4 times.  I have had to reboot it each time to resume using the internet.  Does this indicate a problem with this new airport exteme.
    Possibly, but it may also indicate that the communication between the modem and the AirPort Extreme Base Station (AEBS) is faulty.
    I would recommend that you do the following as a minimum:
    Power-down the modem, AirPort base station, and computer(s).
    While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
    After the base station resets, go ahead and power it back down.
    Power-up the modem; wait at least 10-15 minutes.
    Power-up the base station; wait at least 5-10 minutes.
    Power-up your computer(s).
    In this basic configuration, computers connected to the base station, either by wire or wireless (as appropriate for the base station type), should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

  • BEFW11S4 v4: When connect wirelessly internet drops.

    Ok basicially the laptop is connected via wire to my computer which uses XP.
    Everytime I try to conenct my laptop wireless using windows 7 the internet drops after about 5 seconds when it connects on both devices. Same thing just happened when tried to connect it with Wi.
    Last time I tried this was a during Christmas holidays and I had no problems with it whatsoever, worked like a charm and had multiple connections but know its being stubborn. 
    In addition my dad told me that everytime he connected his laptop on it it gave him trojans.....I doubt this myself but said just incase.
    Any ideas?

    Login to the Router setup page and below change the Wireless settings of your Router.....
    Change the Wireless Channel to 11-2.462GHz...and let the Wireless SSID Broadcast should be Enable and click on Save Settings... 
    Once you are done with the settings then you can try to connect to your wireless network... Once you are done with this settings, then try to connect to your wireless network... 
    If still the same problem then you can try to upgrade the firmware of your Router. 

  • MacBook Pro loses connection to Internet after sleep using Airport Time Capsule

    I recently upgraded to Mavricks and then added a new Airport Time Capsule, and now I my MBP will not connect to the wireless LAN after waking up from sleep mode.  My MBP worked great for over a year with an non-Apple router, so I am thinking that there is a new Apple computer-to-Apple Router issue going on. Any thoughts, suggestions?
    I read all the threads and have followed all the simple advice, such as making sure the Airport is at the top of the network priority list, etc, to no avail.  I end up having to reboot my MBP to get reconnected, which is super frustrating.

  • My MSI K8N Neo4 lose connection to internet

    I have a MSI K8N Neo4 that gives me severe disconnection problems when I use internet. This only seems to happen when I  shut down an p2p-applet (like Steam). I get no error messages, all diods on the modem are on, but I can´t get out on the net. This lasts for about five minutes, and then everything returns to normal.
    I did not have this problem with my other computer.
    I´ve tried to turn off the power saving feature on the network card (or whatever it´s called). After that, I´m out of ideas.
    Any suggestions?
    System: MSI K8N Neo4 Platinum, AMD 64 4000+, 2gb RAM. I use the built-in network card.

    Quote from: Arioch on 30-August-05, 04:09:57
    If you are using the nvidia firewall, uninstall it. It have severe problems with p2p applications, in my experience.
    I use Zone Alarm as my firewall (and I get this problem even if I turn it off) . Does my mobo come with the nvidia firewall as default, and in that case, where do I turn if off?

  • Frequently losing connection

    I use iTunes 12. When I share the iTunes library (on my iMac) I frequently lose connection when my iPhone plays a playlist from the iMac iTunes library. Can you help me find a solution?

    When you are losing your connection does the internet/DSL light go out on the modem?

  • Losing connection to internet

    I have a Mac-mini (Intel) with leopard. I recently connected to Belkin-G-Plus mimo router/ADSL modem, by direct ethernet cable. Sometimes my mac loses connection to internet although its connected to router. on the network panel there is a message saying the "ethernet has a self assigned IP address and may not connect to the internet. after restarting the Mac or swapping to wireless connection I can overcome this. How can I stop losing the IP address ?
    thank you

    You have a "hidden" network on your router most likely and Mac's won't automatically reconnect to them.

  • Wireless Keyboard frequently drops connection after MacBook repair

    Just got my MacBook (1st gen, Core Duo) back from repair from an authorized service provider. They replaced the bottom and top case because of cracks. Since then my Apple Wireless Keyboard (the new one from summer '07) keeps dropping the connection every few minutes. I've never had these problems before (running 10.5.1). The weird thing is that the "connection lost" icons pops up but I can still type. Batteries are at 60% the keyboard is just a few inches away from the MacBook. Can this be related to the new top case?

    Hi Benedikt!
    The Bluetooth module that allows your machine to communicate with the keyboard is located almost right above the opening to your optical drive on the right-hand side of the machine. It's possible that during reassembly the sensor was not reinserted properly or the short, thin, little wire that runs to the logic board was damaged just enough to "work sometimes."
    As you just received it back, I'd recommend contacting the service provider and explain the issue that you're experiencing. The other option, if you have that available to you, is to try connecting another Bluetooth device to your machine and see if it too frequently loses connection. That way you can at least further determine if it's hardware related or peripheral related.
