Mac keeps losing wireless network

This has been happening on and off now for a few weeks but has got much worse recently. My mac suddenly doesn't recognise my BT broadband network name. It often takes up to half an hour before it suddenly comes back on again. Any suggestions? I'd be really grateful as I use the internet for work and it's costing me valuable time.

Hi there,
What I'd suggest that you do is download a copy of iStumbler and run it on your Mac, to see if there are any other wireless networks locally, which could be hindering your attempt to connect and change the wireless channel to a different, less congested channel, if necessary.
I hope this info helps.

Imac keeps losing wireless network connection when awoken from sleep mode

I recently did a archive and install on my Imac and I am still trying to get the kinks out.
Since I did the archive and install, my Imac loses it connection to our wireless router. I assume it isn't renewing its DHCP lease. In order to get a connection again, I have to restart my cable modem and my wireless router.
My network settings are set to join preferred networks by default. My default preferred network is listed and the security parameters have been fulfilled. I am set up to use DHCP in Imac preferences.
Any help would be greatly appreciated.

Hi, See if this helps...
Go to System Preferences
Click Network
Highlight AirPort and click Configure...
Choose “By default, join: Preferred networks”
Select your access point.
Remove your access point with the little minus sign. Launch your keychain access in Utilities and delete your access point keychain entry.
Add it in again after a reboot.

HT1338 My Mac keeps Looking for Networks? The ICON in menu when clicked shows the WI- FI (in gray) ON then goes to Looking for Network again. Shutting down the connection.

My MAC keeps looking for networks? The ICON in menu bar when clicked shows the WI-FI (in grey) it keeps shuting off and disconnecting. Any Ideas???

Test after taking each of the following steps. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions.
2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
4. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
5. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
6. In some cases, the problem has been resolved by repairing permissions on the startup volume.
7. Reinstall OS X.

Any chance there is interference in the area?
Do other devices and computers work? and are they wired or not?

Connect Asus Netbook (PC) to Mac Airport Express wireless network

I'm very happy with my PowerBook G4 but recently bought a Asus Netbook as a light weight travel option. Had problems connecting the Netbook to my home AirPort Express system - it's set up as a wireless connection to PowerBook G4.
The Netbook asked for the AirPort password, but then wouldn't accept it. The Apple phone support people tried to be helpful but thought that changing my Wireless Network password would help. It didn't.
Eventually I found a good article that explained the Netbook actually wanted the Mac/Airport WEP key, even though it asked for a 'password'. The article also explained where to find the WEP key on the Mac, and that I had to uncheck the box on the Netbook that says something like 'The key is provided via 802.1x authentication'.
Not sure if I'm allowed to post the address to that article, but will attempt to do so here:

Hope this helps someone else.

Hello MacNet2. Welcome to the Apple Discussions!
PCs, like Macs, can access wireless networks that use a number of encryption standards: WEP, WPA, WPA2, 802.1x.
WEP is the oldest standard and is no longer considered secure. Your new Asus should support the newer WPA & WPA2 standards. Both are not only significantly more secure, but are also easy to work with when using mixed OS clients. Both the older 802.11b/g or newer 802.11n version of the AirPort Express Base Station (AX) support all of these standards.
Is there some reason that you wireless network is still using WEP?

My iPad keeps losing its network connection. All of the other wireless devices in my house are fine. Any ideas as to what may be causing this?

I have an IPad 1 with 16 G of memory and wiFi only. For the last 2 days it has been dropping off of the wireless network repeatedly. I have a wireless laptop next to it that is fine. I am working where I normally do and have had no problems until the last couple of days. My other IPad works just fine and my macbook pro is also having no problems. Does any one have any idea where to begin troubleshooting?

Just a follow up with a successful ending, I think.
Got the replacement iPad2. Synced it on itunes, put in my old SIM card, and tried it out. I was heartbroken when it had exactly the same problem with wifi connectivity! Dropped my home wifi connection every few minutes or seconds. Had to be prompted to find home network.
Then I tried turning OFF "Ask to Join Networks" as suggested by another poster on Apple Support. Suddenly, I had steady wifi connectivity. I left it that way overnight and even when I woke it from hibernating, it was still connected to wifi!!
Thinking I found the answer, I decided to go back to my original iPad2. I had previously used "Erase All Content and Settings" when I received the replacement iPad2 and so, had to Restore from my iTunes. After doing that, my original iPad2 now holds a wifi connection!! (And I did NOT turn off "Ask to Join Networks".)
So was it fixed by my erasing all content and settings and then restoring it back? Maybe. I called Apple Support again and they did not have any answers or suggestions. They did say that turning off "Ask to Join Networks" would have no effect on connectivity but it did stop the iPad to keep prompting me to choose a network to join!
I would be interested if this "fix" works for anyone else because I see it is a fairly common complaint.

Keep losing wireless signal

My 9300 keeps losing its wireless signal. I phoned and was told to connect to a different network and then connect back to Vodafone which worked for a couple of days but I keep losing and going to GSM and then have to connect to a different network and back to Vodafone.

I assume you are running OS X 10.5.5. Try these simple maintenance routines:
Repair Permissions - /Applications/Utilities/Disk Utility.app. Start Disk Utility, select your HD and click on Repair Permissions. When finished, quit Disk Utility and then restart your computer.
Reset PRAM - hold down Option-Command-P-R keys when starting until you hear the startup chime a 2nd time.
Safe Mode Startup - hold down the Shift-key at startup until you see the login screen. When logged-in, then go to System Preferences/Network/AirPort, click on the 'Network Name:' roll-button, select 'Join Other Network...', enter 'Network Name and select the security type you are using, and finally, enter your Password and click 'Join'. Then, click the 'Apply' button and exit System Preferences.
How are you connected to the internet - DSL model > AEBn WAN port? Check your AEBn Internet setup. Open AirPort Utility, select your AEBn, Manual Setup, Internet - is 'Connection Sharing:' set to 'Off (Bridge Mode)' - set to this if not.
Now check System Preferences/Network/AirPort/ - click on 'Advanced', TCP/IP and confirm that 'Configure IPv4:' is set to 'Using DHCP'.
The above two paragraphs assume that your ISP uses a DHCP server to distribute IP addresses (normally the case).
Hope this helps.

I have multiple macs, on 1 wireless network, never both online at same time

So here's the problem. I have an imac and a macbook air. I've been using my airport express for my wireless network. I've setup the airport express to have its own network name, and its password protected.
I've never had a problem with the express, its always been distributing wireless just fine. And I never have any problems connecting to the internet... EXCEPT if i have multiple macs on my network. (Before wasn't so much a problem, unless a friend came over. But now I have two macs).
On a daily basis, 9 times out of 10, if 1 mac is online, the other 1 get's booted. It acts as if they only have 1 IP address or something to work with from the express. Sometimes renewing my dhcp lease will fix the connection on a computer, but only to boot the other one off. And back and forth this goes sometimes. On other occasions, both lose their connections and cant get an ip address at all; forcing me to refresh the express to factory settings and resetting it all up.
I'm just trying to figure out what i might be missing, or why this keeps happening to me. All software is up to date, and it only happens to multiple macs (My room mate has a pc, but when i had only 1 mac we never had this problem).
Any help or pointers?

Some questions about your settings:
In AirPort Utility, if you do a "manual setup" on your AirPort Express, In the "Internet" panel what settings do you see for
- Internet Connection/Connection Sharing
- DHCP/DHCP Beginning Address (three fields)
- DHCP/DHCP Ending Address
What is "upstream" from your AirPort Express?

How do I set up time capsule to just backup multiple macs on a wireless network without using the TC in the bridge mode?

I have an AT&T modem that serves as our home wireless network. I wanted to backup up our computer data so I got a time capsule to back up our three household MACs. After purchase, I found how that I needed to put the exising modem in "bridge mode" so the Time capsule would establish the network. Four frustrating hours later talking to 3 different people at Yahoo, I got the **** thing established. It worked fine for 4 months - then a power failure forced me to repeat the process again. I had to reestablish everything and it took another 4 hours. After 6 months, another power failure forced me to go through the entire process again. Now, of course, Yahoo is charging a fee to help you establish the TC as the network if you have one of their modems - and to make things interesting, they really don't understand MACs. After 5 hours, in frustration, I gave up and asked the Yahoo folks to just put their modem back in as the network hub and I unplugged the Time Capsule. Now after 3 months of looking at an expensive Time Capsule and searching the internet for help, I figured I try the Apple help network,
I just want to backup the data on my MACS. I have a network in the house that works just fine. How do I configure the TC to work as a backup on a wireless network? It seems like it should be simple, but it isn't. Can anybody help?

I have no idea about the modem and bridge mode (I don't do networking -- hopefully Bob Timmons, Tesserax, or one of the other networking gurus will drop in and address that).
But . . . you should be able to back up to the TC as long as it's on your network and recognized by your Macs. I think being in bridge mode means it will be rather slow, but it should work. Until/unless we hear otherwise, you might want to see #Q1 in Using Time Machine with a Time Capsule.

How do I share files between two Macs on my wireless network?

I have an iMac G4 and an ibook G3 on a wireless network. I have "file sharing" activated on both computers. (Also Appletalk, which may or may not be a misguided move, but I got the idea from OSX "Help.")
When I try to get from either computer onto the other, my computer is recognized by name (another alternative is to log on as a "guest"). I'm prompted for a password. None of the passwords I use works. I've tried the administrative passwords for both computers.
How do I get beyond this hurdle to share files? I've posted elsewhere to no avail. This must be an easy one. How do you share files between two macs on one network?

Do your accounts on the machines have the same short name? It's an issue I've seen a few names.. one machine with bsmith, the other with bobsmith, but the long names for both being "Bob Smith". The login windows would confuse users because it showed their names, but because the short names didn't match, it wouldn't work.
The password you should use is the administrative one, so I don't know why you're not having luck.

New Mac Mini - Existing Wireless Network - Can't Connect

I have an existing wireless network that works fine with an iBook G3. I just hooked up my Mac Mini and it can see the network, but it can't connect. The menu of available networks on the Mac Mini is also much more limited than that of the iBook. Is there an interference issue? If yes, why does the iBook working?

Running an Intel Mac on a Wireless Network with other Power PC Macs

I know changing the Airport to WPA encryption will allow an intel Mac with either Mac OS or WinXP OS to access the airport.
If you have powerPC Macs also, what encryption will allow both Mac (intel and powerPC) and WinXP to access the airport?
Right now either WEP for all Macas or WPA for intel Mac (Mac & WinXP).

Mac Mini (Intel), iMac, eMac, iBook, G4, & Powerbook (all powerPC) Mac OS X (10.3.9) also 10.4+

Hi Sherwood!
If I recall correctly, an update to Windows XP (assuming you're using Windows XP) added WPA support to the existing WEP support. The same applies to Mac OS X.
Regardless, if both OSes are up-to-date they can use either WEP or WPA. But WEP and WPA should not be used at the same time for the same wireless network. Choose one and set your Airport first (create your infrastructure) and then set all computers to connect using that same security (add computers to your infrastructure). I suggest using WPA becuase it is more secure than WEP.
This link indicates when you can use WPA on your Mac and this link indicates when you can use WPA on your Windows system.
Hope this helps! bill

Can't transfer files from my PC to my new Mac over our wireless network

I have a Linksys WRT54G router connected to a cable modem, which is connected to a desktop PC. I have a Dell laptop connected to the internet wirelessly, and my MacBook Pro is also connected to the internet wirelessly. No problem there, the internet works on both.
However, I'm trying to transfer my files from the Dell to my new MacBook, and I get to the point where it asks for my username and password. I've typed in everything I can think of, and the Mac gives me Error -43, 'something or other is not found'.
I don't remember ever assigning myself a username or password when I set up the wireless network. I've had no problem connecting to the Internet with the Dell laptop, but have never been able to share files or a printer with the desktop PC to which the router is connected.
What's going on here?

That would be the username & password of the user account on the Mac.

Why does my mac use the wireless network when the wired network (faster) is available?

My mac is connected to my gigabit wired network, but insists on using the (decidedly slower) wireless network. When I connect the ethernet cable, I can see that Ethernet moves to the top of the list in my network options... but investigation using the Network Utility shows that all the data is still transferred over AirPort unless I disable it. That shouldn't be necessary.

Do you NEED Airport and Ethernet on at the same time?
Like @PAHU said you can use Locations to set up a different connection and/or network when you only need the Wireless.
Setting a "Location" is an excellent way to separate the networks. If you use a "Location" for DSL/Cable and another for "File Sharing" then you can set up which "connection" you want to use and can turn off the others. Or a wireless OR wired Network.
If you also go to the left side of the Network window and select Airport and turn it OFF and you won't have to worry about it anymore. You will have to set each "connection" for each "Location".
I have all my computers hooked to a wired Gigabit switch and the Wired/Wireless router is connected to that. I have "Ethernet-DSL", "Wireless DSL", "DSL OFF", "Wireless Games", "Ethernet Games" (also for file transfers between computers) all on different networks. Takes all of 5 seconds to switch back and forth.

10.5.6 broke mac mail and wireless network

Do not install this update. I did this morning and my computer is toast. Mac Mail repeatedly crashes upon launch and my wireless network is not working.
I have five Mac's in my home all connected with the Time Machine 1 terabyte server/router. I have put the word out not to use this update. I was hoping this would solve a host of 10.5 issues but I can't be up long enough to see what else works or does not.

Ok after restarting about three times I can now see my network. So perhaps Mac Mail will resume normal operation.
