By connecting MBP to wireless network, kills network.

So here is a crazy one.
I just got a work issued  brand new MBP, and as soon as i try to connect it to my network, the network goes down. All the lights are lit on my modem and router and I even called the cable company and they didn't see any issues on their end.  As soon as I reset the router and modem it starts working fine, but as soon as I try to connect the new MBP, it kills it again.  Craziest thing I have seen.  What could possibly be killing my network on this MBP?
I have another mbp, an imac, two iphones, an ipad, and appletv on the network without anything issues.

You have not provided any detail about your setup, connection, equipment, or configuration so any response will be a guess.
I guess you have not configured your computer and to use DHCP.
Second guess, you have not correctly set up your wifi security on your router and computer.
Third guess, you configured your computer incorrectly to share its network connection.
My suggestion, use an Ethernet cable to connect your computer to the router and check its settings and security. Once you get that connection working try setting up your wifi connection.
Provide more detail.

  • MacBook Pro cannot connect to a wireless network

    I am having the following problem with my MacBook Pro trying to connect to a wireless network using a 2WIRE Gateway wireless Router from Bell that worked perfectly until last night. My network preferences pane is saying "AirPort has the self-assigned IP address 169.254.227.XX and will not be able to connect to the Internet." I'm not a techie and I've tried everything I know and cant get my MacBook to connect to the internet using the wireless network in my home. I'm using ethernet connected directly to my router for this! It's killing me. Any help would be greatly appreciated.
    Thanks in advance.

    OK. The wireless network was selected. In the Preferences / Network pane I removed Airport by selecting it and hitting the - button and then created a new Airport by hitting + and selecting Airport. I'm getting the same result. Full network signal once the ethernet cable is connected. Greyed out icon with ! once I remove the ethernet cable and no internet. I appreciate your help so far. Any other thoughts? We also have an iPad, iPhobe, iPod, and two iMacs on the same network. All of them are connected no problem. My Macbook also still connects to the network in my workplace no problem. This all just started happenening yesterday and I don't believe I changed or upgraded anything. I just came home and it had stopped working.

  • MacBook Pro will not connect to Cisco Wireless Network

    I have just bought a brand new MacBook Pro, running Leopard (OSX 10.5.1) and I just cannot get it to connect to the Wireless Network at my workplace.
    The MBP connects to wireless network and authenticates just fine, but will not obtain an IP address from the DHCP server.
    The wireless network consists of 16 Cisco Aironet 1200 Access Points controlled by a Cisco Wireless Network Controller. It does not broadcast its SSID and is WEP 128-bit hex protected.
    Changing the network from WEP to WPA is out of the question for me as this is under the control of my customers IT Department and they do not have any problems with their PCs connecting to the network. It appears to be an Apple issue.
    For reference, my old Vaio PC, my Nokia N95 and my iPod Touch ALL connect to the same wireless network without any problems whatsoever, first time, every time!
    If I boot into Windows XP from my Boot Camp partition, XP can connect wirelessly to the network without any problems, so it is not MacBook hardware related...
    It has to be a bug in Mac OSX... doesn't it?!?
    Things I have already tried (following suggestions on many forums):
    * Switching Airport off/on
    * Deleting various network-related Plist files and rebooting
    * Manually assigning an IP Address (not really permitted but doesn't work anyway!)
    * Disabling all network adaptors except Airport
    AP Grapher shows that the MBP is connected to the wireless network, at good strength, and packets are being sent and received, but Internet Access is not possible as no IP Address has been assigned. Instead, my MBP shows a 169.* IP Address (self-assigned). It should be a 10.1.255.* address.
    Can anybody please help? Thank you.

    i posted this same reply elsewhere because it worked for me for my Buffalo wireless router: try manually setting your IP address instead of relying on DHCP, which sometimes (I don't know why) doesn't work well with Macs. It's a good get around. I am a happy Mac user but nothing is perfect on earth, and when the Mac gives problems, it does give a lot of frustration. Macs are not as easy to troubleshoot as Win because a Mac is built to be user friendly(and it works most of the time), meaning a lot of the background computing stuff is hidden away from users to avoid user accidentally upsetting some settings.
    Unfortunately, the highly automated troubleshooting wizards provided by OS X are not perfect so when these software wizards fail to resolve the problem, like my Network Diagnostics, I have to spend more time tinkering around. There's "Terminal" of course but then most of us, especially PC converts to Macs, don't know how to use it.
    You should also try updating your MBP, see if there are any new updates being released.

  • Two laptops in the same place - only one connects to a wireless network

    I share a room with the guy I'm working with, and his computer (older MB) easily connects to the wireless connection for a fast connection. He has full bars on the Airport icon. My older MBP took several tries to even connect to the wireless network and it doesn't get many bars. It is very slow. Is there any fix to this problem?

    "Is there any fix to this problem? "
    To avoid the +"been there done that"+ scenarios, please advise what troubleshooting methods you have already tried to rectify the problem.
    Have you run the network or router Diagnostic test for example? Check your network and router settings?

  • Unable to connect laptop to wireless network

    My MacBook Pro will not connect to my wireless network, but my iPad does so I know it must be a problem with my computer rather than the network. Any suggestions?
    I'm not sure if there is some obscure setting that I need to change.

    Give us more information, please.
    Is your wireless network supplied by your ISP, your landlord, your own router, or something else?
    What can you tell us about the settings on your wireless network? (Not the passwords.)
    Did this ever work, or is this the first time you have tried to connect the MBP to this wireless network?
    What model/year MBP is this? It has to be somewhat old if it is running Snow Leopard (10.6.8) as per your profile.

  • Can connect to protected wireless network, but no speed or connectivity?

    I saw other people had this issue as well, but I want to make sure my issue isn't a different subject (sometimes I get lost in the technical jargon). Anyway, since I updated my MBP I have been able to connect to my wireless network (password protected) fine, and it shows I have great signal strength; however, when I attempt to use the internet, only the first pages loads really, after that pages are extremely slow to load (30 seconds, etc), time out, or simple can't connect. I don't know what to do. I can connect to the other open wireless networks. I know it is not the router or my wireless card. Any suggestions?

    Does the iOS devices connect to other networks?
    Does the iOS devices see the network?
    Any error messages?
    Do other devices now connect?
    Did the iOS device connect before?
    Try the following to rule out a software problem:                 
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on the router
    - Reset network settings: Settings>General>Reset>Reset Network Settings
    - iOS: Troubleshooting Wi-Fi networks and connections
    - Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
    - iOS: Recommended settings for Wi-Fi routers and access points
    - Restore from backup. See:
    iOS: How to back up
    - Restore to factory settings/new iOS device.
    If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

    Since both iPhone and iPod stopped connecting I suspect a problem with your network.

  • Upgraded 4s to iOS8 and can't connect to certain wireless networks anymore

    I have an iPhone 4s that I updated to iOS 8.  Prior to update, I was using iOS 7 (whatever the latest iteration was), and was able to connect to various wireless networks. Following the update, I am no longer able to connect to the wireless network at my place of work.  It tries to connect, does so briefly, and give me an authentication request (screenshot attached). Blank username/passwords don't work, neither does the network name/password combo.  Choosing cancel will revert the connection back to 3G. 
    To try and fix the problem, I have "forgotten" the connection, re-started the phone, and neither has worked I have reset my network connections, and it worked immediately after the reset.  The phone was inactive for a while, and upon unlocking, it had reverted to 3G.  When I tried to re-connect, it gave the same errors already stated.
    I no longer have a back-up from before the upgrade, so I can't go back to 7.  My wireless connection on my home network is fine.  Nothing has changed with the work wireless since it was working with my iOS 7. It uses a WPA-Personal security, and there are several repeaters for the signal throughout the building.
    What is going on and how can I fix it?

    Well, you could install the drivers to the wireless printer in you other computers.

  • Unable to connect to home wireless network with my iPod touch

    I've had my iTouch for several months now and I'm still not able to connect to my wireless network at home. I've tried the resets and other suggestions I've found in the discussion groups but nothing has worked.
    I have an older Netgear Router MR814v2 and it is unsecured. It is attached to my old desktop, HP Pavilion running Windows ME, which is not able to run the itunes software. My HP laptop is where my iTouch and iTunes software is installed.
    The iTouch displays my network with good signal strength, but when I try to connect I get the "unable to join the network "NETGEAR".
    Going to my router, it does not recognize my iTouch as an attached device. Why is that and what am I missing?
    Thank you for all suggestions and your help.

    I tried powering down the router. When it's off the iTouch does not recognize the network and then when it's powered on again, the iTouch recognizes the network. Unlike the public wi-fi spots that my iTouch responds to, where all the info like IP Address, Subnet Mask, Router, DNS etc are populated in the settings...my iTouch does not populate these fields at home even though it recognizes the network. I still get the unable to connect to network error. Could it be that my router is antiquated and can not support the iTouch? Like I said earlier, my Router does not recognize the iTouch as being attached to it.

    Login to your router and view the DHCP clients.

  • My MacBook pro will no longer connect to a wireless network that I've been connecting to automatically for months and I'm not given the opportunity to re-enter the password.

    I am trying to connect to a wireless network that I have connect to automatically for over a year. When I try to connect I simply get the following message: "the wifi network xxxx could not be joined". I have moved closer to the router as suggested and I have attempted to run diagnostics without luck, I have rebooted, I have toggled the wifi on and off. I'm at a loss now...

  • Since downloading iSO 5 i can no longer connect to a wireless network.

    since downloading iSO 5 i can no longer connect to a wireless network. I have tried both at home and at other wireless hotspots. it would appear that none of the previous wireless connections work either? i just get the error "unable to connect to "x"
    i have tried to "forget" and rejoin but that has not worked either.
    what to do pleeeease?

    Did you already try to reset the phone by holding the sleep and home button until the Apple logo comes back again?

  • Airport no longer connects to OPEN wireless networks

    Lots of people seem to think that their airport keeps dropping the connection to OPEN wireless networks because of the 2008-001 airport update. That is probably only true for a Macbook 2,1 (aka Macbook Core 2 Duo).
    I had the issue on my Macbook 1,1 (aka Macbook Core Duo). I wiped the system clean. Re-installed OS-X. Applied all updates BUT:
    1. Airport 2008-001
    2. Security update 2008-002
    I also downgraded the Airport firmware to 2007-004 (aka version 1.1.9.3).
    Technically speaking this should have resolved the issue but it didn't.
    Why do I believe it should have resolved the issue? Because the same approach worked on the Macbook 2,1 and they both have the exact same Airport card.
    Now I have no idea how to get it fixed - I think I have tried every possible way. There doesn't seem to be any way to contact Apple coz I don't have a support contract.
    But hey, do I need a contract? Apple broke this for me ... they should fix this. I am about to post this as a tech article on engadget and other places because there are SO many people suffering from poor testing on Apple's behalf.
    Apple, please respond.
    Thanks.

    Visited the "genius" bar this afternoon - what a trip!! The guy said this is a Verizon issue, period. I was like you must be kidding, there are SO many people out there who got affected and not everyone uses verizon ... he actually got pretty mad and said you should be using mac hardware (router) and secure network. I even told him my second Macbook is working fine on the same Verizon network. This is their new location in the Northern VA area at Fair Oaks Mall.
    I would call that guy anything but a genius, what a waste of time. This was my first and last trip to a "genius" bar.
    If anyone comes across any new ideas, please share.
    Thanks.
