MacBook killing wireless network

I have the MacBook 1.1 . Router is Linksys WRT54G. Up until approximately 2 weeks ago the network has worked without issue. For some reason the MacBook is killing the wireless network. I thought it was my ISP at first but then narrowed it down to the issue only happening when the MacBook is on the wireless network and then in the past couple of days noticed the network gets killed as soon as the Macbook connects. Im not referring to the just the MacBook loosing connection.... the entire wireless goes down and no wireless devices have access. It eventually comes back up but as long as the MacBook remains in the wireless network it will go back down again.
Snow Leopard... Latest driver... latest firmware. It seems that this started right after a recent update downloaded on the MacBook but I cannot recall what was updated. I need this fixed since my Macbook is my main computer. The others are for family members and Im forced to stay off so they dont get booted.

I have a similar problem with the Linksys WRT54G2 router. The problem seems to come and go but like you rz22g the only time the network is affected is when my MacBook is connected. All other devices on my network work fine PS3, MacMini etc.
Just a speculation but the frequency of this problem started when I upgraded the firmware of the router. I don't know why this would have such a negative reaction. I have also checked that all the router settings are identical to the way they were before the router firmware update.
Oddly enough while I type this my network has been the most stable I've seen it in a while.

Connecting my Sony BD player to my MacBook Pro wireless network. It sees the network but it then asks for a WPA security key. Where do I find this key?

Hi Michael,
It sounds like your router's authentication is set to WPA and thus where the key is established. Does your MacBook Pro connect to a wireless router? If so, that's where you'd need to get the key from via a web-based control panel for the router or if it's an AEBS via AirPort Utility.

Macbooks lose wireless network connections when they go to sleep

I work off a Mac in a busy office. We have a password-protected wireless network. The password is saved on my computer. Our landlord has an unprotected network. When I boot up, my Macbook tells me that it "can't find" any of my "trusted networks" and asks me if I want to join my landlord's. I say, no, pick the password protected network from the airport menu and log on. When the computer goes to sleep (or I shut the lid to put it to sleep), upon waking up, it asks me the same question. Usually takes a few seconds to find the right network.
I have this problem in two offices with two wireless, password protected networks. One of the networks is brand new. My boss got a MacBook Pro running Snow Leopard and now he's having that problem on the brand new network, recently upgraded for future Electronic Medical Records applications.
Only his problem is worse because it won't remember the network password. He gets the "not connected to the internet message," runs network diagnostics, chooses the protected network, reenters password, finally connects to the Internet, then has to close the computer to run back to work. (Quite comical if you're not getting the heat for it.)
Note, neither of us have this problem in our homes where our computers run on Airport Extreme networks.
Is there anything we can do to ensure that the Macbooks always find the password protected network and we don't have to re-enter the network password every time?

Thank you very much for your answer. Now I admit I'm a total non-techie. I see how to choose networking from system preferences and change location from automatic to new network. Then I can manually add the network. But do I also have to 'set macs to remember previous networks' and if so, how do I do that?

Why won't MacBook accept wireless network?

I've set up a wireless network on my iMac using a Netgear combo modem and wireless router. But my MacBook won't accept the network. Any suggestions?

Try these steps:
Shutdown and restart the modem
Shutdown and restart the router (alway restart the modem first)
Go into System Preferences > Network
Select the AirPort from the left hand side
Select the "Automatic" location
Click on Advanced
Select the AirPort tab and enter your network name
Select TCP/IP tab.
Configure IPv4 Using DHCP
Now click on Renew DHCP Lease. After a few seconds you should get an IP address (probably 192.168.x.x)
Click on Proxies tab.
Select Auto Proxy Discovery and Use Passive FTP, clear all other options
Click on OK and Apply, etc.
Good luck

Cannot connect macbook to wireless network

Hey, I wonder if someone can help? I live in the uk & want to connect my nephew's macbook to his home wireless network.
His network is run off a Windows based pc, I have read in the forums that this is ok. He has a rather old pc that has no wireless card so I have installed a Netgear usb adaptor which runs just fine. The pc can "talk" to the Orange Livebox (Livebox -3660) and the pc can connect well, to the internet via the Livebox. So I have a stable internet connection.
The problem is that we cannot get the macbook ( a few months old only ) to connect at all to the net!
On the macbook there is no signal reading at all, airport is scanning for a network,it finds Livebox-3660 ok but when we enter the password the macbook says cannot connect!
Its curious that there is no signal reading at all on the macbook, yet it is right next to the livebox?
When I take the macbook home to my house, it connects immediately to my imac....full signal no problems. All systems go...
I must be missing something obvious ?? The security set up is currently WPA-PSK I dont know if this has a relevance? should I change this to make it more compatible to WPA2 ??
Much appreciate the help of the good people on this forum.
Thank you in advance. W

Sorted it!

W540 kills wireless network

Hello all,
I have an interesting problem here.
When I connect my new W540 to my wireless network, it kills all the connections to all wireless devices. (wired connection stays up)
To be able to connect again, the router must be restarted.
I tried with a TP-Link router and a Linksys router, both give me the same problem.
I am using windows 8.1 and updated all the drivers, but so far the network keeps failing.
Wireless card is Intel Dual Band Wireless-AC 7260
Any ideas are welcome!

So a colleague of mine has the same problem, and today she tried to work from home office.
She called me and reported that she cannot work because the router shows a limited connection. She has the same problem!
I advised her to disable wireless, plug in the cable and restart the router, so for now it works.
Does anyone know if this issue would be covered by warranty?
I am not planning to buy a USB adapter as a solution.
Always working with a network cable is not a solution either.

IPhone kicks Macbook off wireless network?

Alright, this is rather bizarre. I have D-Link DIR 625 wireless router, and I had no issues with Macbook (and other computers) connecting to it at all.
I also connect my iPhone to the same wireless network. However, all of a sudden (the only change I know of is update to 10.5.7), if Macbook is connected to the wireless first, and I connect iPhone second, the Macbook looses the connection. If I restart the AirPort on the Macbook, then they both co-exist on the network with no issues. No other computer on the wireless network is affected.
Does anyone know what could be going on here? This is reproducible each time. All I have to do is turn iPhone on (it auto connects to the preferred network) and Macbook is out .

Try:
- 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.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iOS device.
- Make an appointment at the Genius Bar of an Apple store.

Macbook V Wireless network

Hi,
I have an ongoing problem that only occurs on my MacBook Pro, no other device in the house has an issue.
When I open up my MB sometimes I am already connected to the network but more often than not I have to rejoin.
I am asked for a WPA2 code which I enter and the MB tells me repeatedly (up to 20 or 30 times) it is invalid ( which it isn't), I keep pressing JOIN and finally it accepts the password. This varies as sometimes it will accept it within a few attempts.
My question is who is going to win the Superbowl...........no sorry, does anyone know why this happens and if there is a way to stay connected to my home network?
Thanks in anticipation

See if this helps:

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.

How do i connect my MacBook Air to a Printer on my Wireless Network

How do i connect my MacBook Air to a Printer on my Wireless Network ? The printer is connected to a PC running Windows 7. That PC is connected to my Wireless Network. MacBook connects fine to Network, but can't find Printer.

Hi Kappy,
Thanks for your response. I followed your instructions (for Mac OS 10.6.7). It seemed to set up OK, but when I tried to print I kept getting the following Failure Message "Session Setup failed : NT_Status_Invalid_Parameter".
When I get the "Advanced Window" should I enter anything into the "Location" field ? Maybe I am not entering the correct Workgroup, Server or Sharename ? Is there a way to make sure all of that is correct ? I went on to the computer that the printer is connected to and verified all of that, but am not sure I looked in the right places.
When I print via my Home Network from another Windows 7 Computer to the same PC, it works fine. I just can't get it to Print from my MacBook Air.
I thought of using the IP Address. How do I find the IP address of the Computer that is connected to the Printer ? Is it what they call the IPv4 Address, or the IPv4 Default Gateway ?
Appreciate any help you can provide.

Brand new macbook pro cannot connect to wireless networks

The first time I called apple tech, they thought it was a problem with my internet provider. I've called 4 times now, and I'm still getting the runaround.
I have an old (2001) G4 sitting right next to my macbook pro which can see numerous wireless networks and connect to them all. A strong connection at that. However, my brand new (refurbished) Macbook Pro Intel etc,.... supposedly best computer ever made, . . . . can see the same wireless networks but has never been able to connect. As a student, I saved for a year to buy this notebook so I could work at cafe's & study with my friends. My friends with PC's can all connect to these wireless networks. My friends with older, less expensive notebooks can connect no problem. I have never been able to connect. Bought this peice of junk 2 1/2 months ago - only because I didn't want to be stuck at home anymore with my desktop. Stupid me to trust apple.
I wish I could get my $ back, but I'm now being told that it's 30 days too late. Before they told me it was a minor thing and some software update could fix it. I did as told. downloaded and installed their 10.4.8 thingy - deleted all the keychain stuff - nothing. same peice of junk.
Now they are telling me to go back to the genius bar where folks are just rude to me and tell me they can't help me becuase I bought a "refurbished" model that didn't even save me $25. What do you know.
Anyone having problems like this? Anyone out there who can help me?

Okay,
I apologie for calling it a peice of junk. I know you all probably worship this machine. I'm just really frustrated. I noticed that this is a very common problem - though most of the posts identical to mine have dissapeared from apple.com - this well known defect is all over other discussion boards and websites like macdefect, etc,....
So, can any of you tech gods help me with this very well known, common problem that I haven't been able to fix with 10.4.8 upgrade?
Thanks for your time and assistance,

MacBook loses wireless connection when iPod touch connects to network

hi
ever since upgrading to 10.5.5. on my MacBook i've had the "intermittent network connection" problems that have been described and discussed (without any real solution from what i can see) in another thread.
PROBLEM: every couple of minutes my MacBook loses connectivity to the network - the AirPort icon still says that i'm connected, albeit with one less bar than before, but i can't connect to anywhere, not even to the wireless router - and to re-establish a connection i need to switch off AirPort, switch it back on, it will then reconnect, and after two minutes or so i have to do it all over again because the network connection drops again.
NOVEL OBSERVATION 1: reinstalling the 10.5.5. combo system updater helped somewhat. i used to get an error in system.log about there being too many state transitions on the wireless network and about network traffic reduction measures being taken to overcome this problem, but after reinstalling the 10.5.5. combo system updater this message never appears in the logs and I get kicked off only sometimes (see what i say in point 2 below)
NOVEL OBSERVATION 2: now my MacBook will only lose its connection to the net if i switch on my iPod Touch and switch its wireless interface on. in fact, the only way to avoid the MacBook getting constantly disconnected is to make sure that the wireless interface on the Touch is switched off in the Touch's system preferences; if I just sleep the Touch (top button) without switching off its wireless network interface first in its System Preferences, then the MacBook will keep disconnecting even while the Touch is in sleep mode (presumably the Touch keeps polling the network or something, even while it's in sleep mode).
DIAGNOSTIC NOTE 1: I have another wireless device (my Nokia E51, which has wifi capabilities) and if I connect it to the wireless interface then the MacBook's connection isn't dropped - i.e. the MacBook only loses its wireless connection when my iPod Touch connects to the wireless network.
DIAGNOSTIC NOTE 2: I have upgraded my wireless router (before I had a Linksys WRT-54GC, now I have a Netgear WGR614v9) but that has made no difference.
DIAGNOSTIC NOTE 3: I have also tried altering the router's settings (i have played around a_lot with this, trying every combination I could think of - e.g. staple down particular devices to particular ip addresses, use only 802.11g versus automatic b/g, etc) but that has made no difference either.
RANT:
The only thing that prevents these disconnections from occurring is to keep the iPod Touch's wireless switched off, which ***** because if I'm in the kitchen I can't have it switched on to monitor my email (yes, I've no life, i hang around waiting for emails), or if I go have a lie down and want to check out stuff on the net, or to browse the iTunes music store or whatever, then I know that my connecting my iPod Touch the computer will be disconnected.
This obviously *****, right? And a lot of people are having wireless problems with their MacBooks, right? And these problems seem to have been around for over a year, right?
So why hasn't Apple solved this problem yet? Or am I just being melodramatic?
Your thoughts on any or all of the above, or flames if that's your preferred method of communicating, are invited. =)
Cheers

Having the same problem here. As a first time mac user, Apple has certainly made a bad first impression.
For me, the issue seems to occur when transferring files between computers that are connected to the same access point (when transferring files from wired computers on the network there is no issue). My vista laptop and every laptop I have tried has worked perfectly fine with this access point so I am 100% convinced it is the mac. Basically when I copy the files, after about 100mb, I am unable to access anything on the local network or internet until I restart Airport. The weird thing is that even though I am unable to access anything, the airport utility says it is connected. I might also note that the wireless signal strength is full.
If I can't get this figured out in a few days, this computer is going back to the store where it came from and I will officially label myself anti-mac. This type of issue is just unacceptable for something so main stream.

When I switch my time capsule to 5.0ghz mode the range of my wireless network drops significantly. Near the Time Capsule my Macbook Pro works fine, in my bedroom I have almost no signal. In mixed mode it works fine. Any ideas on how to get 5.0 working?

Thanks, W

I'm not sure if you understand that 5 GHz has some upsides, but also some very significant downsides.
The upside is that the 5 GHz signal will allow faster speeds.
The downside is that you must always give up something in order to gain something else.Unfortunately, the marketing hype about 5 GHz does not go into very many details about this.
In the case of 5 GHz, the 5 GHz signals are much weaker than 2.4 GHz signals, so they do not travel as far or penetrate any obstructions like walls or ceilings nearly as well as 2.4 GHz signals. In many cases, in order to get good 5 Ghz performance, you literally have to have almost a line-of-sight relationship between your computer and the wireless router.
If you have a new dual band router, which broadcasts both a 2.4 GHz and 5 GHz signal simutaneously, your Mac will connect to the best signal quality automatically depending on its location in relation to the router. In the same room, without any obstructions, it will connec to 5 GHz. But, take the laptop down the hall a few rooms and around the corner and the Mac will connect to the 2.4 GHz signal because at that location, the 2.4 GHz signal is not only stronger, it is also faster.

Connecting MacBook to printer via wireless network

I have a wireless network via cable modem with some PCs attached and a printer but am having trouble connecting my new MacBook to the HP LaserJet 2100 printer via wireless. I do not have airport express and not sure I need it to have the MacBook print to this printer. Please advise.

Hi topgunner,
How is the printer connected? Are you trying to share it via a PC through wireless? Or is it connected directly to a router/hub that is enabled for printer sharing?

I have a wireless network at home. I run my iphone and ipad on it with no problems. Just purchased a MacBook Pro, and now my wi-fi keeps disconnecting and i get an error message saying another device is using the same IP address. What does all this mean?
