Wireless losing connection?

Hey guys,
Had Infinity for a day and a half now, and sometimes my laptop (and wireless PC) drop connection.  It's for a couple of seconds, but it's enough to cancel any downloads, stop any browsing etc.
I've tried changing the channels (as well as looking at inssider), but still no luck.  Looking at the event log, it seems that it issues DHCPs a lot - is this the cause, or a result, of the connection drops?   I've changed the refresh time to 21 days.
Last time I had an issue with wireless, it was with Sky, and they sent me a new router - it was fine after that.

as you are now trying to conenct to a new HH3 I would check to make sure the drivers for my wireless cards are up to date.  I would check the manufacturer's website for updates and not rely on windows update

  • Wireless losing connection to wired network and lan

    I have a customer that has an 871W ISR. They are using WEP encryption and a mix of b and g cards. Recently they have started losing connection to all of their wired network resources and the wan, but they don't lose association with the 871W itself. They show excellent signal strangth and keep their IPs. A reboot of the router immediately fixes the problem. There seems to be no pattern or common event that triggers any of this. Anyone else seen this problem before? It started happening after I did a sh tech and the router locked up halfway through it, so I had to reboot. I've reloaded the image thinking that may fix the problem and it has not.

    You can clear the interface statistics on the Detailed Status tab, and let traffic run for a time, then refresh the statistics. The ratio of errors to good packets sent and received should be better than it was prior to the test.

  • Been losing connection for magic mouse and wireless keyboard

    When I have my MBP running Mavericks in clamshell mode, I lose connections to both magic mouse and apple wireless keyboard in clamshell mode. I've tried all the PRAM SCM, aluminum foil and paper tricks. What I then did was test what happens when I leave the MBP open rather than in clamshell mode and it appears to avoid losing connection, at least that is what I've concluded with Mavericks for now..... anyone else able to replicate this? Having to leave the MBP open is not ideal.

    Barry, thanks, still not working.  I've tried every thing I can think of or have read, what I'm concluding is that there is either a problem with Mavericks or something has changed on how bluetooth works in Mavericks. Did not have this problem for the last 4 years. I can reproduce the problem when I close the laptop. I had the Bluetooth and wireless card checked out and replaced about 3 weeks ago. Problem has continued.

  • Wireless N WRT300, Constantly Losing Connection

    This router Constantly loses the internet connection, and I am HARD WIRED to this router, is this not somthing they should have mastered Ages ago?
    The wireless signal is Weak and constantly loses it's connection.
    I've tried calling them to fix it, I've changed the MTU, from 1500, to 1400, to 1300 etc, etc, I 've also set it to auto.... nothing.
    Every so often the internet connection Drops, the only way to fix it, is to Unplug the router and plug it back in. Soon as this is done the internet works instantly again. I can see the wireless being buggy, but NOT the hardwire, there is NO excuse for this.
    And to boot I just love how bestbuy wont allow any exchanges on this type of hardware, And cannot return it, and I cannot exchange it for a different router. I can only echange it for the exact same make and model of router.
    Message Edited by curtisbouvier on 11-16-200603:06 AM

    I also have the wrt300N router. I am losing connection all the time either wirelessly or wired. When the router works it is blazing fast, but every 2-5 minutes it just HANGS which is REALLY ANNOYING!
    I have updated the firmware. This happens on my wired XP machine, my wireless XP, or on my apple laptop. It is not the computers becuase my old wireless router (linksys i forget the number, but it was a b system at least 4-5 years old) did not have this issue....
    I saw on some threads that port forwarding may help? Is this a solution? Anyone have any ideas? Clearly by reading the posts this is not an isolated problem....

  • Wireless Keyboard losing connection while BT headset in use

    Hi,
    I got a Samsung SBH500 Stereo Headset, and when I'm listening to music and using my Apple Wireless Keyboard and Apple Mighty Mouse, the keyboard keep losing connections.
    Already tried to trash the preference file, change the Favorite status of everything, but the problem goes on and on.
    While writing this post the connection was lost twice, and it's becoming frustrating...
    Help, please.

    I decide to run some test.
    1) Wireless Keyboard + Wireless Headset + Wired Mouse works fine.
    2) Wireless Mouse + Wireless Headset + Internal Keyboard works fine.
    3) This is obvious, but to said i tried: Wireless Keyboard + Wireless Mouse works fine.
    So here's what I'm thinking...
    A software/firmware problem with the Macs bluetooth or the headset uses way too much data so 3 devices is too much. I don't think is too much data, because if it wore probably would disconnect the devices randomly, not only the keyboard.

  • Wireless Keyboard keeps losing connection

    My wireless keyboard started getting hung up on a key and continues to to type it until the KB loses connection. Then it reconnects and sometimes repeats this several times before it starts working normally again.
    It has also just been randomly losing connection without hanging up on a key.
    Batteries are new and the iMac/keyboard and mouse is less than a year old.
    Any thoughts?
    Mouse is losing connection too at times, but nothing like the keyboard.

    Hello B:
    One thing to try is to make the devices "favorites" Directions for that are in other posts of mine.
    However, the keyboard (from your description) could be faulty. Since it is less than one year old, I suggest you call Applecare with a warranty issue. I had a KB replaced (in warranty) a couple of years ago. Apple replaced it and paid the shipping both ways.

  • Losing connection to HP7520 on wireless network

    I probably would be OK if I only had one pc but I have 3 - Win8, Win7, and Vista. Tech support had to install printer after downloading software from HP. Apparently disc is worthless.
    It was installed using an IP address which I think was a mistake. IP addresses change and this may be the issue here.
    When I am on the WIn8 or Win7 pc the printer goes offline or is not connected. 
    Question: should I share the 7520 on al pcs or none at all?
    Question: If I disable my security software firewall, should the printer be found and installed on wireless network OK?
    Part of my problem and confusion about this issue is how the printer is defined when viewing Printers on each pc. There are HP 7520 Series, HP 7520 Series(networking), HP 7520 Series(Fax) - to name a few - depends on the pc OS.
    Some definitions have the IP address shown when viewing the printer properties, and other definitions show the serial number. I have installed a lot of HP printers on a wireless net and never had these issues.
    Any ideas on why I keep losing connectivity to printer?

    Hi jghiller,
    Question: should I share the 7520 on al pcs or none at all?
    The printer should not be shared from one computer to another.  Each computer can directly access the printer.
    Question: If I disable my security software firewall, should the printer be found and installed on wireless network OK?
    The firewall can cause problems, but not like they used to.  With this being a current printer, most firewalls should work fine with the printer.
    Dropping from the network:
    There are multiple possibilities.
    1. Try turning off UPnP in the printer embedded web server.  Type the IP of the printer into a web browser to access the EWS.  On the network tab, selecting Networking on the left side and then UPnP.
    2. If your router supports double width data channels, try changing the router to use single width channel.  You will need to access the EWS of the router.  Most routers will say either default or double.  There might be a number listed instead.  Try setting the router to 20Mhz channel width.
    3. Also, setting a static IP for the printer could be a good idea.  That way the printer IP won't change and possibly get lost by the computers.  This setting also appears in the printer EWS.

  • Losing connection to wireless network every week

    I really don't understand why this keeps happening. I have a PC (Windows XP) connected to a cable modem. I also have a WRT54G wireless router connected to the modem, following instructions on the CD-ROM that came with the router.
    Across the room, about 8 feet away, I have another PC (Windows XP) with a Compact Wireless-G USB Network Adapter with SpeedBooster model WUSB54GSC installed in one of the computer's USB ports. Again, I followed installation instructions on the supplied CD-ROM and things came together and I was able to connect to the internet through the wireless router.
    A week later, the 2nd computer lost it's connection with the router, so I tried "repairing the connection" but that didn't work. I ended up uninstalling the software and starting over. This time it worked, but the connection was "connection 2."
    Every week, usually on Sunday, I seem to lose my connection with the router and now I am up to "connection 6." Other people I have spoken with say they never loose their connections and the folks at Road Runner think it must be a problem with the router. Who knows? I wouldn't be surprised if I set it up incorrectly and have probably confused it with all the uninstalling and reinstalling I have done.
    Any suggestions? When it does connect, it works fine. I just don't understand why it keeps losing it's connection every Sunday.
    Thanks for any help/advice anyone can offer.

    Sounds like you are not connecting to the correct network.  Let say you called your network ORLANDO.  You should see ORLANDO in view your network connections. Also, if you would click on view workgroups computers, you should see all your computers listed.  You will have to log on to your router and make sure everything is set up properly.  XP default is MSHOME.
    I have had my share of problems using WUSB54GC on my windows 98 se.  No problems with XP sp 3 using identical adaptor.  I am been at this for a couple of months.  Usually unpluging adaptor and repluging it will solve the problem.  No problems using XP. I have even switch adaptors on both computers.

  • Windows 8 keeps losing connectivity

    Hi, not sure if this is unique but for the past few weeks Windows 8 has been losing connectivity every few minutes when browsing web pages, playing games etc. I am sure it's windows 8 as I have another work laptop using XP that I can be on all day via a
    VPN and that does not drop at all (it would normally drop within a few seconds of losing connectivity). I've done a lot of searching on the net for the same issue, others seem to be having similar things happen such as slow speed but can't find anything that
    matches, hence this separate question.
    I have also tried swapping routers to no avail. The thing is, you wouldn't know anything had happened from the network connectivity. Suddenly a page won't load. The wireless connectivity at the bottom right of the screen shows a full 5 bars (not limited
    connectivity). The way to get it back again is to leave it for a few minutes or disconnect from the router and reconnect again. Even whilst typing this I have had to do that twice.
    I'd appreciate some suggestions!
    Many Thanks, Paul.

    Hi,
    Does this issue occur with both wireless and wired?
    I suggest to perform these tests to troubleshoot the issue:
    1 Update NIC card for your machine
    2 Temporary disable firewall and antivirus program
    3 Logon with Safe Mode with Networking
    4 Update framework for your router.

  • Questions About Losing Connection

    Like other people I've noticed here, my WRTG45 v5 wireless router has recently started losing connection to the net multiple times a day. At first, we thought it was because our modem was old, so we bought a new one, but it didn't fix anything. So here are my questions:
    1. My dad seems to think that a configuration or setup CD (that we lost) is required to make the router work with the new modem. Is this true? I don't think so, but I have to ask just so I can get him to move on.
    2. I noticed in other posts here that programs like Bittorrent can cause the router to be overworked or whatever. This might explain our problem, as I use Bittorrent a lot (but not everytime the connection has dropped). If this is indeed the problem (or contributing to it), is there anyway to deal with it while still being able to use the program?
    For the first couple months, the router was working fine. Even with Bittorrent running a lot, and all the computers (2 wired, 1 wireless, and 1 wired X-Box) engaging in various activities on the net. So this is very puzzling to me.
    One more bit of information, I have given every computer a unique, static IP address. However, I noticed recently that when I look at the router configution after typing in its IP address in a web browser, that it is set to DHCP Enabled.
    Also, in the advanced TCP/IP settings for this connection, under the WNS tab, the NetBIOS setting is set to the default of using NetBIOS from the DCHP server.
    Since I am using static IP addresses, could these DHCP centered settings be causing problems? Although, even if they are, it still doesn't explain why the router was working fine months ago (unless someone changed stuff without my knowing).
    Anyway, any help at all would be appreciated.

    I assume you meant that you had a WRT54G v5 router.
    First of all, the setup CD is not required.  All router settings can be made by going to the router's web pages at 192.168.1.1
    It is possible that the static LAN IP addresses are causing your problem, if they were not set up correctly.  Linksys has a strict set of rules to follow regarding static LAN IP addresses.
    With Linksys routers, a fixed (static) LAN IP addresses must be assigned in the device that is using the address.  So you need to enter the fixed address in the computer or printer, not in the router.
    When using a Linksys router, any fixed LAN IP address must be outside the DHCP server range (typically 192.168.1.100 thru 192.168.1.149), and it cannot end in 0, 1,  or 255.
    Therefore any fixed LAN IP address would normally need to be in the range of
    192.168.1.2       thru 192.168.1.99  or
    192.168.1.150   thru 192.168.1.254
    assuming you are still using the default DHCP server range.
    Also, in the computer, when you set up a static LAN IP address, you would need to set the "Subnet mask" to 255.255.255.0  and the "Default Gateway" to 192.168.1.1
    It is also important that no two devices on your network be set to the same static LAN IP address.
    Check all of your static LAN IP addresses.  If you have violated any of the above rules for static LAN IP addresses, it could be the cause for your problem, and you should fix it before attempting any other router repairs or changes.
    You should leave the DHCP server turned on.  This way, if you have a visiting friend who you want to connect to your system, it will be easy to do.   Leaving the DHCP server turned on should not cause any problems, even if all your addresses are fixed.   In general, you should let the DHCP server assign all addresses, unless there is a specific reason to use a static address.  You can mix static and DHCP assigned addresses on the same LAN, as long as you follow the above rules for static addresses.
    Linksys routers have had problems when BitTorrent is used.  Your router has new firmware posted that should improve compatibility with BitTorrent.  It is firmware version 1.02.0   You will need to download and install this firmware (after fixing the static address problem, if any).  (Note:  When you update your firmware, you should use a computer that is wired to the router.  Also, when you do a firmware upgrade, turn off all other computers on your system, and unplug all other wires from the router.)   After you have installed the firmware, and powercycled the router, you will need to reset your router to factory defaults, then setup the router again from scratch.

  • Mouse losing connection

    My mouse is losing connection with my computer on a regular basis, and regaining it after around 1-2 minutes. The problem is happening every day, sometimes up to 5 times, during which time the mouse is completely unresponsive. I've tried rebooting, turning the mouse on and off, changing the batteries but nothing seems to work. Can anyone help, as I've never had this problem with wireless mice before?

    Hello:
    Try resetting the PRAM and SMC.  It is also possible that the mouse is failing.

  • N8 and wireless router connectivity

    I have a problem with my new N8.
    If I use the N8 at home it interferes with my broadband wireless router (BT Homehub) resulting in my losing a wireless internet connection on my laptop.  The laptop tells me I have Limited Connectivity.
    I must thenkeep my N8 turned off and restart the wireless router in order to regain an internet connection on my laptop.
    Thanks

    Which BT homehub do you have (there's been three)?
    Have you been into the routers settings and tried changing the wireless channel?

  • WRE54G losing connectivity

    A few months ago I purchased a WRE54G range expander. After some initial setup issues, it worked great until a couple of days ago. The expander stopped working and seemed to have reset itself. After a couple of conversations with tech support, the range expander finally had connectivity, however, I am now continuously losing the connection. I have downloaded the latest firmware for the expander and my WRT54GS modem, I have changed settings, turned my beacon interval down to 50, and am still losing connection. Does anyone have any other ideas of what I could try, or have a had similar problem that they were able to resolve? I would appreciate any help anyone can provide me with.

    did u try a firmware upgrade on the expander too ?? if not , then give it a try .. try wireless channel - either 1 or 11 , RTS and Fragmentation threshold - 2304

  • Losing Connection From BT Hub

    Hi All,
    Not posted here before but hopefully I provide the info needed
    I have a BT Home Hub 2.0 (Black with blue lights down right hand side) with firmwhere 4.7.5.1.83.3.31 (Type B) and a Broadband Accelarator/I-Plate at the main phone socket in the wall.
    I have worked from home for a number of years and rely on the internet, I have 2 laptops (1 wireless and one ethernet) and 1 gaming machine (also on ethernet).  The problem I am having is that my gaming machien on ethernet randomly losing connection with the BT hub while my other 2 laptops on wireless and ethernet remain connected.  It's strange as the others are still working. I can either fix the problem by clicking on the connection icon near the clock and letting windows fix it or restart the machine where it also fixes it.
    The gaming machine spec is:
    Manufacturer:        Self built
    Processor:             Intel Core 2 Quad CPU @ 2.40GHz (4 CPUs)
    Memory:               8 GB DDR2
    Hard Drive:            Western Digital Caviar Blue 250GB SATA-II 16MB Cache
    Video Card:           NVIDIA GeForce GTX 570 12804MB GDDR5
    Operating System: Windows 7 Professional 64-bit (6.1, Build 7600)
    Motherboard:        NVIDIA NForce 680i SLI
    Computer Case:     Antec 900 Ultimate Gaming Case
    The only thing I have changed on my gaming machine is the graphics card, sometimes the internet would be fine for hours then lose connections, othertimes I lose connection after 20 minutes.  I have not managed to tie it down to any software or game that causing the problem. It's really strange. Before this problem, the gaming machine has been fine on ethernet connection for the past year. I have not changed any other hardware of BT Lines etc.
    Any pointers would be greatly appreacited
    Thanks!
