Windows 7 notebook prevents other devices from joining network

hey,
i've nosed around the web and the apple forums and haven't turned up a possible answer so here goes a new thread.
i have (and have had) a 100% apple ecosystem at home for years w/ no trouble: airport extreme (recently replaced a flying saucer with whatever was current as of June '11), three extremes (two from the g-only era, one newer n model, all configured to "connect to wifi network") and iphones, an ipad, and macbook pros. hunky dory, no problems for literally years.
this summer, family came to live with us and spoiled the pot with an Acer laptop running win 7 sp1 (double checking everything was up to date was the first thing i checked). w/ this new addition to our family of electronics i've had the following problem:
the windows 7 machine will stay connected to the network fine but any of the other apple devices that try to connect can't. this is true of iphones, ipad, and macbook pros (4 of them) running either Snow Leopard (up to date) or Lion (up to date). the extreme has not crashed, it's just not connecting any other devices --i.e. the windown lappy is connected and working fine.
i end up having to reboot the extreme and then things are fine. often, the windows 7 laptop is being used for skype, so there's steady traffic to it, even when other devices can't connect. the SSID is hidden, i've been flipping between WPA2 only or WPA/WPA2 which seems slightly more robust. and the windows laptop is a personal machine, not configured to connect to windows domains.
any thoughts or ideas on how to resolve things so i don't need to reboot my extreme daily would be appreciated.

Just a thought, maybe un-hide your network's SSID (hiding it is of little security value anyway).  For some reason, and I don't know this to be true, but my experience with Apple products is that a hidden SSID causes wi-fi connection problems with Apple clients (but perhaps only when there's a Windows machine in the mix?)
On my network (currently a Linksys router, soon to be AirPort Extreme) if I hide the SSID then only my Windows boxes will reliably connect -- the iPhone, iPod, and Mac all go "duh?" and lose connection.  Maybe in an all-Apple network this doesn't happen, but based on my experience and that of others I'm wondering if its your hidden SSID that's causing the problem.

  • Macbook loses wifi, prevents other devices from connecting too.

    Hi guys
    I have a strange problem whereby my macbook seems to lose its wifi connection, and prevent all other devices from connecting to wi fi either.
    its very odd as the router still shows up in available networks with full signal, but I cannot connect to it and neither any other device, including ipads, mobile phones and various other windows laptops.
    This can only be fixed by restarting the router, which is a pain as its tucked away upstairs!
    I know its my macbook casuing the problem and not the router as the problem didn't exist until I came home from uni, and it hasn't happened at all over the last two weeks while my laptop was away getting a new battery. Today I got the macbook back and the problem has returned! More than a coincidence me thinks!
    This can happen three or four times an evening and is very frustrating, especially for the rest of my family!
    Once I have restarted the router the connection normally comes back, however sometimes I get an exclamation over the wifi logo in the menu bar, saying no internet connection.
    My macbook is a aluminium 2ghz core 2 duo running OSX Lion with all the most recent updates, and the router is a BT homehub 2.0.
    Any help would be gratefully appreciated!
    Thanks in advance.

    I have had this problem after my (work provided) 2008 macbook was updated to mountain lion. I have tried all the suggested fixes with some success, resetting PRAM has occasionally sorted this out, deleting the wifi and then re-starting and restoring works, but is very tedious to do every time you need a connection!!
    A further wifi problem caused by the update was the loss of access to passwords in keychain- checking the 'access by all applications' box in keychain preferences helped reconnection too.
    The tip I wanted to pass on is this-
    If you are having these problems, and resetting the wifi has sorted it out, turn off the wifi Every Time before you shut down the machine. This simple action seems to allow the mac to keep it's settings intact, and it can be turned on again without any problems the next time you boot the macine up.
    The connection problems can't be hardware- this machine is as fast and stable as the new retina mackbookPro it sits beside- when it can see the signal......

  • HT204291 Airplay on Mac prevents other devices from using airplay

    I have successfully connected my mid 2011 Mac mini to my 3rd gen Apple TV to allow for extended desktop on Mavericks. The problem is after I have disconnected Apple TV from the Mac mini and turned off airplay features, the Apple TV stays connected to the Mac mini, causing the Apple TV to turn on and stay on, even when the Mac mini is asleep. I have also just found out that this unwanted connection prevents my other iOS devices from using Airplay with Apple TV. The device will connect momentarily the then be kicked off with the Apple TV showing that it's "playing" an "Untitled" track from "Internet radio". At the time of this incident, the Mac mini was on sleep mode. This problem was resolved when I shut down the Mac mini.
    What is causing this unwanted connection and how can I be able to use Airplay from devices without having to shut down my Mac mini?

    Thank you for the quick reply HACKINT0SH. But it does not solve anything.
    When i move the iMac to the first floor and connect trough wifi it works. When I move the device back to the cellar then it works via LAN for a day or so... After some time the Airplay Icon is just gone
    It seems that the Mac is not searching anymore for AirPlay devices or the broadcasts goes nuts.
    Is there any way to search manually for AirPlay devices?

  • How to ensure your computer information is kept private and to prevent other devices from accessing it

    Recently I was on a public network and it seemed to me that my volume kept on increasing while I was trying to watch a video. I contemplated that it might be my key stuck, but it seemed fine every other time I used it (and is fine now at home). That led me to the conclusion that someone was probably remotely accessing my macbook's volume setting for some malicious prank.
    How would you be able to tell if a device is remotely connected to yours, without authorisation?
    ====
    I also looked up the possibility that people were using 'ssh' to harrass me. I'm not quite sure how it works, but I would like to make it so that people would not be able to find my computer's information to connect to it in the future.

    TM backups retain the same exact permissions as the originals. so if other users did not have access to them on the main drive, they won't have access to them on the backup drive either.
    and be VERY careful playing with permissions on the TM drive. it's easy to ruin TM backups that way.

  • How do I stop other devices on my network from receiving me iMessages? I send an iMessage to someone and everyone on my network sees my conversation.

    How do I stop other devices on my network from recieving my IMessage?
    I send a friend an iMessage and other people on my network get to see the conversatiom.

    Are you sending a group MMS? If so that is why. Also if others are using the same apple id as you then they will see all your imessage texts. You need to change your apple id on you device.

  • Is there anyway to set a passcode for my iPhone/iPad, but prevent the device from being disabled?

    My wife and I have iPhones, and also have an iPad. We also have three children, and recently they have been trying to guess our passcodes so that they can watch videos and play games. Trouble is, after 10 attempts, the device will disable for 60 seconds, and then if the 11th attempt is wrong, the device will disable for 5 minutes, etc. My iPad is currently disabled for 60-minutes. Grrr.
    Is there anyway to set a passcode to keep the children out, and yet prevent the device from being disabled on successive attempts? I realise that this feature is there to protect our devices from brute-force attacks, but we are being penalised, in that our devices become disabled for a period of time.

    Well, so you have to ask: Is the problem your iPad or your children? Another question: If they're not to watch videos or play games, then why are they on the iPad in the first place?
    Obviously you already know the answer to your question; there is no way to set it up the way that you want to. If you nonetheless feel that you should be able to do that, then put together your best case for it and make your wishes known directly to apple via their established Feedback links:

  • What's the username & password when i connect device from cisco network assistant

    what's the username & password when i connect device from cisco network assistant?
    http://i200.photobucket.com/albums/aa273/wallfire02/Capture_zpsa8f5fd2b.jpg

    Although that may be true...
    If I click the "Connect As..." button it asks for a username and password.
    I've experienced connecting to other user's computers on a network.  To gain access to their computer, I just use their username and password.  I've done this before to transfer files without using a flash drive or burned disk. 
    I'm trying to find out what I'm supposed to log on as to gain access to this device...
         My point is that yes, I'm connected to it by wifi.  Otherwise it wouldn't show up; ha-ha! 
    Is my point really that hard to grasp?

  • Can I reject other devices from connecting to my U330p?

    Hi,
    I've installed McAfee anti-virus software in my 1-mth old U330p. However, I'm getting annoyed by the frequent McAfee pop-up messages informing me that a few devices have been connected to my laptop. My issue is, I don't recognise those devices. Is there a way to reject other devices from auto-connecting to my laptop? 
    Please help. Many thanks!

  • How to restrict users working on Windows 7 clients from accessing Windows Explorer and other systems in the network through Group Policy with a domain controller running on Windows Server 2008 r2

    Dear All,
    We are having an infrastructure setup of around 500 client computers managed through group policy.
    Recently the domain controllers have been migrated from Windows Server 2003 to Server 2008 R2.
    Since this account requires extremely strict environment, we need to figure the solution for restricting the users from access anything locally.
    It would be great if you can assist me with the following query.
    How to restrict users logged on Windows 7 clients from accessing Windows Explorer and browsing other systems in the network through Group Policy with a domain controller running on Windows Server 2008 r2 ?
    Can we disable Network Tab on the left hand pane ?
    explorer.exe is blocked already, but users are able to enter the Windows Explorer by clicking on the name which is visible on the Start Menu.

    You cannot block explorer.exe when you do not replace the shell - the
    desktop you see effectively IS explorer.exe...
    Your requirement sounds like you need a custom shell:

  • Safari of my Macbook (on WiFi) suddenly fails to connect to the Internet.  A popup window message says another device on the network is using my computer's IP address.

    But then there was still no Internet access even after I have disconnected all other home computers (a total of four including the Macbook and one iMac desktop.  For simplicity, I shall categorically called them Mac hereafter unless otherwise specified.  The Macs are operating on WiFi.). 
    The window message recommends changing the IP of either the Macs or the other device.  The latter of course does not apply because I don't think the other device is one of my computers. 
    My questions:  
    (1) Why did that happen suddenly since the Mac and other computers on the WiFi was working fine in the morning (as well as days before) and then all of a sudden an unknown device is using my computer's IP?  As far as I (we) can remember, we did not do any thing unusual this morning nor had we downloaded any special programs.
    (2) How do I change the IP since it requires Internet acess to do it and since I can't access the Internet on the Mac? 
    (3) I am almost sure the problem is not caused by the Internet service because when I connected the Ethernet cable from the DSL modem to an old Windows PC, I got Internet via Internet Explorer.  [I am actually sending out this message via IE on my PC.]  However, when I cennected the Ethernet line from the modem to a WiFi router (Airport Extreme) and then connect the router and the old PC, I did not get Internet on either the Mac nor the PC.  Similarly, there was no Internet on both Mac and PC If I connect Ethernet only between the modem and the router but not between PC and router.  So, the question is whether a third unknown party has gotten hold of my Mac IP address and is trying to break into the Mac?  Can it steal my personal info?
    (4)  How can I repair the Mac now and prevent future recurrences?  Is changing the IP address the way to do it?  (But like I said before I had tried but could not change the IP because I did not have Internet access on the Mac.  Is there an alternative method?) 
    (5) I wonder if a computer's IP address remains constant if you don't change it.  The reason I am asking this question is because the aforesaid window message on the Macbook--not sure about the iMac--shows a different IP address--a few numerical digits were changed--almost every time it pops up following every failure trial of mine to access the Internet.  Was the Macbook trying to change the IP for me or was there some thing not right?

    Re: Another device on the network is using your computer's IP address.
    This message/problem was occuring intermittently for me in a household with two MacBooks accessing one Airport extreme.  Rebooting the modem and router would only temporarily fix the issue for me, so I spoke with a friend who works for Apple and it seems that the Airport Extreme settings were at the root of our particular issue.
    The router(Airport Extreme) recieves only one IP address from the modem and in order to allow it to share the IP address with two computers at once, the solution in my case was through:
    Applications>Utilities>Airport Utility>Manual Setup>Internet
    under Internet Connection- Select "share a public IP address"
    under NAT, check the box for "enable NAT Port Mapping Protocol"
       (this will allow the sharing of one public IP address with multiple devices)
    if this is a new setting, then click "Update" and the Airport Extreme should reboot itself with new settings applied.
    When all else is working properly, this is a satisfactory solution in my case.

  • VPN connection works, but can't ping or access any other device on remote network

    I have an OS X Lion server at work (uses a static IP of 192.168.2.10). VPN is setup and works.
    The work network's router has an IP of 192.168.2.1 and hands out IPs of 192.168.2.100-149. The VPN service is configured to hand out IPs of 192.168.2.150-170.
    My home network uses a router with an IP of 192.168.1.1 and hands out IPs from 192.168.1.2-49
    Both routers are using subnet mask of 255.255.255.0
    The problem is, I can connect to the VPN just fine and access all services running on that same OS X server like iChat and AFP file sharing. But, I cannot directly access any other device on the office network like client machines or even trying to log into the router's GUI interface. Pings timeout, etc.
    Example:
    At my home, I have a local IP of 192.168.1.12 and I connect to the work VPN. It assigns me an IP address of 192.168.2.151 and I'm able to connect to iChat on the OS X server that has a static IP of 192.168.2.10
    In terminal, I try to ping the router on the work network (192.168.2.1) and I get no response (even though ICMP response is turn ON). I try to ping another OS X workstation on the work office, and get no response.
    I'm not sure how to fix this, or whether I need to change settings on either router or the server.
    Would greatly appreciate any insight or help on this. Thanks.

  • How to delete a static device from "my network on Verizon MI424-WR?

    Can anyone tell me how to delete a device from the "My Network" panel that connected using a static address and not DHCP? I have the Verizon MI424-WR (rev E).

    I had to do some digging, but I believe I found it.
    Log into your router. Go to Advanced, and click Yes to proceed. In the right, bottom section, click on IP Address Distribution. From that page, click the Connection List (middle) button.
    This brings you to the list of connections, and the far-right column has a button to remove entries.
