Losing connection to AirPort network

My PowerBook G4 loses connection with my AirPort network (created by an older Airport Extreme 802.11g) every time it goes to sleep. I think this is normal, but the problem is that it does not automatically reconnect once it reawakens. It will only connect if I manually select my network from the pull-down network menu on the desktop. Believe me, this gets very tiresome after a while. Anyone know of a fix?

Some complaints about this have been posted in Getting Online and Networking. Don't know if there's a fix yet:

G4 (800MHz) connects to airport network via N300 wireless modem but won't bring up a browser page (Safari or Firefox)

G4 (800MHz) connects to airport network via N300 wireless modem but won't bring up a browser page (Safari or Firefox) - so the connection is there, everything says its a goer - I get a clear black signal icon in the menu bar on top, and a clear signal strength in the Internet connect dialogue box - - but when I run either of the browsers, it just says 'not connected to internet' - even for the 'software update'.
the N300 is a Netgear N300 Wirelsess Modem Router (model DGN2200) - ADSL (802.11 b/g/n)

My Apple TV is losing connection to my network

I've had the Apple TV 2 for several months, and it's been working flawlessly until a couple of weeks ago, when it started losing connection to my home network. In other words, I turn it on and I can't use it until I reconnect to my wi-fi password, etc. This never happened at all until a week or two ago, and it's happening nearly every day--once I reconnect it's fine, but the next day or so I have to re-enter my wi-fi password, a major annoyance. I have a feeling my router may be experiencing some problems, but still wondered if anyone else has this problem and if so, how it was resolved. In the past if I had any operational problem, just unplugging it and plugging it back in works fine, but this is a completely different issue, one of connectivity, and seems specific to the Apple TV and not necessarily any of my other internet devices. Once reconnected, BTW, all my previous settings seem to be intact.
Thanks.

I'm having the same trouble as the OP, started around the same time. AppleTV 2nd gen losing wifi PW about once a day.
* The only recent infrastructure change was me converting from ISP-provided wifi (2.4ghz "G") to an Airport Extreme (5ghz "N"). That's been working perfectly since April, and this ATV2 problem started only a couple of weeks ago (early July)
* I am the only 5ghz user around here. Yes, I checked with inSSIDer. Yes my PC is on the 5ghz band too.
* I haven't actually timed it, but it seems to happen almost exactly 24 hours apart - in my case it happens during the hour I'm out walking.
* I don't believe it's associated with sleep mode. Mine is set to 4 hours, and:
--- I can pause a TV show, go walk for an hour, then come back and it's d/c'ed
--- I can pause a TV show after a reconnect, go to sleep for the night, wake up, wake the ATV2, and it resumes with no problems.

Losing connection to my network, drops mine, goes to Guest

I am constantly loosing my connection to my network. It drops back to "Guest Network." This is causing my Time Machine to not back up until I go to the menu and reselect my personal network.

XP Pro on MacBook Pro Cannot Connect to AirPort Network

I just installed Windows XP using the Boot Camp set up utility. After I installed Windows, I went to set up a wireless network and went through the full process of setting it up. Since I've done that several times, XP Pro on my MacBook will not connect to my AirPort network. I have an airport network on one end of the house and on the other end, I have an airport express to increase the signal.
Any ideas?

I feel your pain! I can tell you how to get into a protected net ... just not how to STAY connected for any appreciable time! Haven't figured that one out!
Go to your wireless connection icon ... bottom rhs of tool bar (XP)
- 2x click that icon ... that'll bring up your connection
- Highlight your connection
- Select the "Change Advanced settings"... lower lhs of screen
- When the next window pops-up, select the "Wireless Networks " tab
- The next window should display your connection ... if not highlight it
- Select properties
- In this window you should select:
- Shared for Network Auth
- Select WEP for Data Encrypt
- Input your Network Key (You can get this off your Airport Admin Utility by bringing up the Airport and selecting the "Lock" icon that's named "Password". Select password and it'll give you the hexadecimal equivalent. Input that into your Network Key window and authenticate.
- Select OK and you should be good for about 5 mins!

Apple TV no longer connects to Airport Network

I operate an Airport WDS network composed of 2 A. Extremes and 1 A. Express. Several Macs (10.4.11) are connected to the network. So far, the Apple TV used to work fine.
Added a new iMac running 10.5.1. Everything works fine EXCEPT the Apple Network which sees the network but cannot connect to it (Error -3) when I enter the network pwd. Still, this pwd works for every other computer.
I tried everything on the ATV, including a complete reset ("menu" + "-" keys on the remote). Same error again and again.
ATV diags say the device is ok.
How could this be related to my adding one single Leopard computer on the network?
Any ideas or suggestions?
Thanks,

Here's what I found and how to get it working again.
What I found: The TV has network address that is wrong (not the same subnet) as the host mac running iTunes.
The fix - and this depends on your network configuration - you must ensure both Tv and the host computer have acquired IP addresses on the same subnet, say 10.1.1.x and 10.1.1.x+1, or 192.168.2.x and 192.168.2.x+1.. Otherwise iTunes will not connect to the TV.
You will have to force this by setting the IP addresses manually, as I have done.
The clues....
I first looked at the TV to find its network address and tried to ping that from the mac (use the Network utility or the Terminal). This failed which immediately implies the IP addressing is all screwed up.
In my case I have my iMac directly connected to the AppleTV via a wired ethernet connection.
From the iMac to my ADSL is wireless (Airport), and this internet connection is shared to the ethernet connection.
The TV was configured to use DHCP and the network settings shows it expected to find the iMac at 192.168.2.1, ditto the DNS and router.
What I discovered is this. Turn on the TV screen and set TV to show its network settings, then shut down the iMac. In my case ATV then shows N/A for all the IP addresses.
As the iMac is rebooted, the TV is assigned an address in the 192.168.x.x range, and is given 192.168.2.1 for the DNS and router in this range also.
But if I open the iMac's network panel it has self-assigned an address in the 168.x.x.x range, so its no wonder the TV and iMac are not communicating - they cannot because they aren't in the same subnet.
In my case:
iMac: open the network control panel, and set the IP address to "Manual with DHCP". Assign an address - I used 192.168.2.1.
TV: set the network settings to manually adopt an address of say 192.168.2.4, and set it to look for the router and DNS (the iMac) at the iMacs address as above.
Hey presto TV and iMac connect again.
I'm not sure whether the TV or Leopard is at fault, but that I had it working fine in Tiger and that in Leopard, ping failed with the error "unable to allocate resources" leaves me to suspect Leopard is at fault.

Why do i get an error message while trying to connect to airport network?

i just installed an airport card in an iMac G5, archived and installed Tiger, updated everything (while connected via ethernet) and now when i'm trying to connect to the wi fi network in the house i keep on getting a message saying there's an error while trying to connect to the network. i have a PowerMac G5 connected wirelessly with no problems, i have an iBook connected to an Airport Express via ethernet and a Mac Mini connected to an ethernet port on the Airport Extreme Base Station. there's a DSL modem connected to the other ethernet port on the Base Station. occasionally the iMac will connect to the network, but that's once every few restarts or log outs.
help.

i called apple support and they said after trying tons of software related tweaks and such that it's probably the airport card and to see if it's in correctly and if it is just exchange it for a new one.

Won't automatically connect to Airport network after 10.4.8 update

After updating my Mac Mini CoreDuo from 10.4.7 to 10.4.8, it will no longer automatically connect to our Airport Express based Wi-Fi network. Even though the Network settings in System Preferences have not changed, and they do list it as the preferred network, it still will not automatically connect after log in.
Does anyone have this issue, and know of a solution?
(aside from the workaround of manually connecting after log in, and after waking the computer from sleep).
Background: My setup is to join preferred networks by default, the network name continues to be the one listed, the network still continues to show up in the Airport network list in the upper right corner of the screen. In essence, the Mac sees it is there but just won't connect to it. We have two other Macs in the household, both are PowerPC based, and both were updated to 10.4.8, and they have no issues. They continue to automatically connect to the Wi-Fi network we have. This seems to be with our Intel Mac only.
Mac Mini CoreDuo Mac OS X (10.4.7) Mac OS X 10.4.8

This all happens most likely due to a corrupted key chain (entry).
For instance, if you choose to keep your local Airport password stored in your personal key chain it needs to be accessible by the private Apple Airport Framework used by the network preferences. If this by any means, is not possible - the automatic login into you Airport WiFi network cannot take place.
All you have to do to get this fixed is:
1) Launch your Keychain Access Application located at: /Applications/Utilities
2) Open the Keychain First Aid (under the Main Menu: Keychain Access)
3) Set the Radio Button to Repair and enter your Keychain Password (most likely your personal password)
4) Start.....
Now after your personal keychain (name=username) is repaired it might be listed double in your Keychain List Window (it depends how you've setup the keychain). If so, NEVER DELETE ONE OF THIS ENTRIES because that's obviously a cosmetic bug in the Keychain Access Application but not harmful. Just look in your local Preferences Folder, locate the file "com.apple.keychainaccess.plist" and thrash it. Re-launch the Keychain Access Application and there is only one again.
Restart your Mac and........
After all I think anything should be back up to how it supposed to be. :-))

Can't connect to airport network (but macs can)

I have an airport extreme base station that usually provides connections to three computers, an iMac, macBook, and one pc. For a while however I haven't been able to connect the pc to the airport. The network does have security in the form of a WEP password. I don't know much about network security however, and the windows interface for wireless networking has different terms than that for mac. Even stranger, the PC doesn't even see the base station, nor does it see the network in the wireless network connectiosn window, but sometimes it does see the network (with a good signal) but it cannot connect. I have all of the software updated, so I don't think it would be that, but maybe there's something I'm missing? The PC lately has been connecting to other wireless networks around the neighborhood, so I don't think it's the network card either.

Machines losing connection to the Network

We are experiencing some irregular network issues whereby we have 2 G4 Mirror Door Desktops acting at servers (10.3.9) and a variety of Powerbook G4s and Macbook Pro's (10.4.x) which are continually dropping off the network sporadically. Apart from these two desktop servers, all the machines affected are laptops strangely enough.
Firewall is not enabled on the Macs.
The Macs lose all network connectivity including printing, internet connection and server connection.
I have tested pinging to and from the Macs and the results are always as though they are off the network. The Macs can however ping itself indicating it can see a network. Whe you remove the machine from the network and re-add it, the IP address range is 169.x.x.x. This is because by default, Apple allocates the user with an IP range so far off the network that its indicating it can see a connection (ie ethernet card and cable) but cannot see the network.
To get the machine back on the network, you need to remove and re-add the network cable to get connection again. We looked into every possibility inclusing Firewall or DNS issues.
We have compared the switches and vLANs and they are all the same; we have checked that Appletalk is broadcasting correctly through the switch; we have added the machines with a static IP address (servers have static IP addresses anyway)and the machines still drop off; we have altered DHCP lease renewal to a longer period and it still dropped off; removed Appletalk from a machine and it still dropped off.

It may be a 'typo' by you, but forget about 'appletalk' - this is not relevant to your problem (and pretty well redundant now). This looks like a TCP/IP issue.
What is doing your DHCP? Presumably you have checked to ensure that there is only the one dhcp server in your network, and another has not accidentally been enabled (on a server, router or airport). What is the dhcp range for the DHCP server?
Your post suggested that the servers, with static IPs, also 'drop off' the network. So a server IP cannot be pinged from a lan machine which has a correct IP assigned to it (rather than one which has a 169 address which obviously will not be able to ping it) ?
On your laptops, when connected via an ethernet cable, have a look at Network Prefs-> Show: Network Port Configurations. In what order are these? Specifically, I am wondering if Airport is getting prioritised above Built-in Ethernet and maybe there is a 'rogue' airport network which the laptops discover and attempt to join ahead of built-in ethernet.

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.

Losing connection to iTunes / Network

I continue to have the same problem over and over and am hoping someone can assist. The ATV continues to lose it's wireless connection to the network/iTunes. Only way back is to reset the router and ATV; it will then stream anything just fine. It will sometimes work for a couple of days and then just lose the connection. When it is working, I can put the ATV in standby, shut down the computer and start it back up and it will still work no problem.
Has anyone had this happen to them where it keeps losing the connection? It's not an interference issue so I'm not sure what else to try.
Any help would be much appreciated. Thanks all.

Losing Connection to BB Network (BES)

My wifes 9550 keeps losing connection to the BES network. Happens about once or twice a month. She is not a power user and doesnt install / add anything. It has happened since she got it back in NOV. I updated her to 607 when that was releaed....thinking it might help (Havent pushed her to 713 yet). But it still happens!! Again today it did. She wont get emails etc till it connects.
Shes not doing anything strange.. the little 4 dots next to 3G just disappear. I have the same phone, we are both on VZ... and I have had no issues like this.
Any Idea?

Hi StaticFX,
Is it possible you can PM me your wife's PIN? I can take a look to see if there is anything unusual going on from our side.
Also, have you contacted Verizon about the issue?
Thanks

IMac Won't Connect to AirPort Network

Hi, folks —
I just switched my home wi-fi from a Netgear 600N to an AirPort Extreme Base Station with an AirPort Express extender closer to my office. Both are configured correctly—they work great with my iPhone, iPad, and MacBook Air.
But my Intel iMac from 2008 doesn't seem to be able to connect to the network at all—it just times out—and I have no idea why. Any ideas?
Removing the extender doesn't seem to help.

rkaufmann87, I'm embarrassed to admit that I actually just fixed the problem by using the wireless diagnostic tool that I didn't realize was built into System Preferences—it cleared whatever was confusing the system, and now the wireless connection is working great. I'll now be able to install the 10.8.4 update wirelessly, like the good lord intended.
Thank you for all of this.

Losing Connection to the Network

Hello all,
For several years I have had problems with getting disconnected while playing video games whenever someone calls. Now I am having the problem but nobody is calling it just kicks me offline for no reason. I thought the problem before was that my phone and wireless were the same Ghz (2.4) but now that the phone isn't causing interference I don't know what is. My Router is a broadband 2.4 GHz Wireless-G router - Model # WRT54GS. I also have a AARIS Touchstone Telephony Modem that Comcast gave us. The problem that I thought I solved was by adding in a linksys Wireless-G Range Expander so that the connection could go from my room upstairs down to my basement, this is not the case anymore. I seem to be able to play for 20 minutes or so but then it says I do not have connection to the network, the only things I can think of are:
1. We need a new router, this one is old and outdated.
2. With no password on our connection someone is using it and causing too much activity. If that's the case should I get rid of the expander and or add a password?
Thanks for any of your help or suggestions.

Also change the channel on the router's wireless to 11. This is the least used frequency.
Also keep your phone away from the router. Can't tell you how many calls I got because of cordless phone interference when I worked tech support
