Why does Airport card lose AX network connection intermittently??

I'll be working, and then abruptly the Airport card in my iMac G4 loses the AX connection to the Apple network, and can't find any network. My iBook picks it up fine. Then, maybe within a half hour or so, it suddenly finds the AX Apple network again. All the while my iBook is fine. The only difference between these computers is that the iBook has an Airport Extreme card, and the iMac has an Airport card. And, I'm also in the same room as the AX station. iStumbler appears to show a loss of signal when this occurs, but that doesn't explain the iBook working fine.
I looked in the AP mgmt utility, and saw this:
"Deauthenticated with station (iMac mac address) (inactivity)."
And then:
"Deauthenticated with station (iMac mac address) (received invalid class-3 frame)."
What is the problem here??

iBook G4 / iMac G4 / iPod 20GB Mac OS X (10.4.7)
iBook G4 / iMac G4 / iPod 20GB Mac OS X (10.4.7)

I'm looking into that possibility.......have a cordless phone in the office, a PC, cell phones, etc. Will clear them out and recheck. The maddening thing is that the iBook is totally bulletproof even in that environment. Why would the iMac be having these issues, but not the iBook? Is Airport Extreme more robust, or that much better than Airport?
Even now, the iMac shows no network - yet I'm writing this on the iBook right next to it, and it's had no network interruption whatsoever.
Do you have any knowledge of those "error" notations from the syslog? Could they be pointing to anything else?
Thanks much.....

Why does my iphone lose its network connection

Have a new iphone and a wireless network at home. The phone connects to the network ok, but as I move around the house it loses its connection. When attempts are made to reconnect the iphone replies "incorrect password", despite the fact that the password was stored from the previous connection. Attempts to reenter the password do not help. So far the only thing that allows a reconnect is to completely reset the network settings on the iphone, after which it connects once but then disconnects again later. The issue may be related to the fact that there are two wireless routers in the house and the disconnections may be related to moving from the domain of one to another.

Hi Frayyan,
Welcome to the Support Communities!
The article below will give you some insight about how to optimize your settings to improve the battery life on your iPhone:
iPhone: Hardware troubleshooting
Battery life seems short
Click ( www.apple.com/batteries/iphone.html) for tips on how to prolong iPhone's battery life.
Try turning iPhone off and then on again.
Connect iPhone to iTunes and restore iPhone.
If the screen shows a low-battery image, the battery is low on power and needs to charge for up to ten minutes before you can use it.
When charging iPhone, make sure to leave it charging until it is fully charged.
Note: When charging using a computer, don't connect iPhone to a keyboard. Also, the computer must be turned on and not in sleep or standby mode. If iPhone is connected to a computer that's not turned on or is in sleep or standby mode, the iPhone battery may drain.
I hope this information helps ....
Have a great day!

Orig. Airport card loses IP, maintains connection to Linksys network

I'm posting here because I don't see a listing for plain old Airport cards. If there's a better spot in the forums for this, please let me know where it ought to go.
The setup:
Dual 867 Power Mac G4 (MDD) with old-school Airport card (both purchased back in 2002), running 10.4.10, and connecting to a Linksys wireless network (WRT54G wireless G-router, with a WRE54G wireless-G range expander). For the most part, this has worked out very well for the past several months.
The problem:
The IP address seems to drop out randomly, but not the wireless connection itself. I'll lose internet access, but have a full four bars on the Airport signal indicator. Pinging either the router or the extender fails. Shutting off Airport via the menu bar and then turning it back on will bring back the IP.
The bigger problem:
This used to happen once in a while, now once or twice a week, but switching the Airport off and then on brought it back. Now it's happening every five to ten minutes, starting this evening. It does it with both static and dynamic IP addresses; the static IP remains in the System Preferences window, the dynamic one actually vanishes until I restart the Airport card.
I ran into wireless problems yesterday where the SSID and the network just up and vanished. I'd previously attributed this to environmental considerations since it had happened a few times before and normally fixed itself within 30 minutes to a few hours. After it failed to come back by this morning I upgraded the firmware on both the router and extender to the latest versions available from Linksys. All was right with the world for several hours.
Until the problem with the IP dropping while the wireless connection remains returned. Then it got worse. Now it drops on a far more frequent basis than before. This only happens on my desktop Mac. I'm on my Windows XP machine (same room, same wireless network, using a Linksys USB wireless adapter). The Windows machine is fine; it does not lose IP address when the Mac does. Since I have a full connection and the Windows machine doesn't seem bothered at all, I'm guessing it's something to do with the Airport card in the Mac.
Apple's software update tells me there's no new software available for my machine, which leaves me with no idea what's causing this or how to fix it.
Any advice, solutions, or tips are greatly appreciated.
Thanks!

Some of this might be review for you...
An IP address is how the data finds you on your respective network, like the street address on your house. When you boot up your computer and connect to your network your computer is connecting with either a static or dynamic IP address. Static means every time you boot up, your machine is using the same one you've assigned to it. Dynamic means that each time you boot up your machine gets whatever one is next in line.
Odds are if you've never set this, you're using a dynamic address which means you're using DHCP. To check, go to your System Preferences -> Network Preferences -> and double click on the Airport connection. You'll see a few different options, so click on TCP/IP. That will show you if you've got a static IP address ("Manually" appears on the pull-down menu) or a dynamic one (DHCP).
Unless you have to forward ports or are looking for volumes on your network using a static IP, DHCP for a dynamic IP is fine.
The "new" Airport card wasn't a 100% fix. My IP address does seem to mean nothing every once in a while. I sometimes have to switch the Airport off and then turn it back on. Since toward the end, my old Airport card stopped seeing the wireless network entirely, even when my XP box saw it clearly, replacing the card was still a good idea for me.
Good luck!

IMac loses wireless network connection intermittently - Linksys wrt54g v.5

I' ve setup a new 17" iMac for my folks, runs great with this big exception - it will spontaneously, but regularly lose connectivity with my Linksys WRT54G v.5 router (usually after sleep, but not always - and sometimes when starting cold). Restarting the iMac, fidgeting with internet connect, etc. will not fix the problem. ONLY power cycling the Linksys router will allow the iMac to once again see the network. Once the router is recycled, the network reappears with its strong signal indicator in the menubar (the iMac is maybe 20 feet from the router). When connected, network performance and quality are at expected levels (ie, no slow d/l speeds etc.).
To make it interesting, I also have a PC running XPsp2, that experiences NO network hiccups when the iMac loses connectivity. And the iMac does this whether or not the PC is on, etc. But if I turn the PC on when the iMac cannot connect, the PC has no problem joining the network or accessing resources.
In otherwords, I sense a problem between the Linksys router and the iMac (either the Airport card or OS X).
I HAVE upgraded the Linksys firmware, upgraded all Apple software, changed router channels, and tried both WEP and WPA Personal, all to the same result. I have also scoured every corner of Apple and Linksys boards, only to find many people with this same issue and no answers.
Brownie points for answers!

17" Intel iMac Mac OS X (10.4.7)
17" Intel iMac Mac OS X (10.4.7) Linksys WRT54g ver.5

Well, so far so good!
I would never have found the preferences, so thank you thank you thank you for that Sherry. I never did delete ALL the prefs, just the ones obviously labeled as network related. But so far, no dropouts for 2.5 days. If Apple has anything up detailing this procedure, I sure couldn't find it - so you saved me there. I thought we left all the "delete prefs" solutions behind with OS 9.
BUT, I was a bad boy and actually made two changes at once. Not recommended procedure, I know, but I was desperate. In addition to deleting/recreating the above prefs, I also changed the router from Channel 1 to Channel 11. Maybe the Airport card likes Chan. 11 in this application? Dunno if this was part of the solution, but worhwhile info for anyone else in the same situation.
Thanks again Sherry, I've marked "helpful" and "solved" accordingly.

Why does my iPad lose the network I'm on when it goes to sleep?

I Just moved in with someone and I have to manually join the network every time I turn my iPad on. Now all of a sudden, every time my iPad goes to sleep it loses the connection all together. I've already tried resetting the network and also location in the settings. Any other ideas?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Why does Airport take so long to connect to the wireless LAN?

I have one of the Core 2 Duo MacBook Pros. I notice that whenever I wake up my Mac from sleeping, it takes a good 10 seconds for it to find and connect to the LAN. By contrast, Windows computers seem to find it and connect almost instantly.
Aside from having WEP encryption, there's nothing special about my LAN. It's a Linksys WRT54G, and I'm not hiding the SSID. Also, my home network is at the top of my list of preferred networks.
Once connected, I don't notice any problems. I haven't tried any specific tests of local throughput, but web browsing and other internet traffic with the Mac is no slower than the top speed of my broadband connection.
Also, I've talked with other Mac users, and they don't report wireless connections taking so long to be established.
So, what's going on here and how can I fix it?
Thanks!

My guess is that your connection will appear even faster, although I have no explanation for that, only my experience since I installed the same update.
Yes, your MBP firmware appears to be up to date, although the documentation is confusing. If your firmware wasn't updated at all, it would probably end with 00, instead of 01.
Software Updates needed for Macs will appear in Software Update's automatic offerings. I'm not sure what might have happened with the AirPort Extreme Update, although I suspect it might have only been called for if a Mac was using an Apple Base Station.
If you use Software Update to do your updates, you can check the Software Update panel of System Preferences, and on the "Installed Updates" pane, scroll down and check to see what was installed and when. I installed the same AirPort update the day after release - but then I was having an issue and was checking Software Update every day for that update to show up for my iMac Core Duo.
[I'm not sure that firmware updates are listed there at all, perhaps only software updates.]
To check for all downloadable updates on your own, click on "Downloads" in the Support menu bar at the top of this page. That's where firmware updates will appear if they are not included by Software Update. The last firmware updates have been appearing in Software Update. The first in 2006 didn't, but that created so much confusion among new users that I have a feeling that Apple has changed the procedure to automate it rather than have it be search and find:) Only time will tell.
Your mention of your printer - you could check to see if Samsung has a firmware update for your printer, but no, you can't use a mixed network, you need everything connected to be using same encryption method with same network name and same password.
I believe I understand the new AirPort Extreme "n" Base Station will support two separate simultaneous networks like that, one on the 5MHz band and second on the 2.4MHz band, but the older equipment can't do that.

Why does my iPad lose the Internet connection ?

Why won't my iPad battery recharge? Sent this message before & would

I didn't do the most recent upgrade as I had problems with it when I did the previous one. I have the IPAD WI-FI 32GB . It seems to be charging ok . I did a Sync yesterday and now it won't connect to the Internet although it was working fine last evening and I didn't change any settings.
When I plug it in to my iMac, the iPhoto applicaiton opens and I have to open the iTunes application even though I have it set to open when I connect the iPad.
Appreciate any help or suggestions you can offer. Thank you in advance.

Why does AirPort Extreme stop working when I plug in a USB hard drive?

Why does Airport Extreme stop working when I plug in a USB hard drive? The USB drive has its own power supply. I've tried isolating the hard drive from Airport using a powered USB hub to no avail.

The USB port on the AirPort Extreme is borderline as far as its ability to supply adequate power to a hard drive. Another way of saying the same thing is that this is not a high power USB port, like you would find on a computer.
Your 2TB drive likely requires a bit more current than the USB port on the AirPort Extreme can supply. It is also possible that the drive's firmware may not support a network USB connection....only a "local" connection to a computer. Check with Seagate support on that possibility.
Try using a powered USB hub with the 2TB drive....and make sure that the drive is formatted correctly in Mac OS Extended (Journaled) or FAT32....which the AirPort Extreme USB port can accept.

Why does my iPad2 suddenly keep losing connection on facetime?

Why does my iPad2 suddenly keep losing connection on FaceTime and tries to constantly reconnect?

Does it happen anywhere that you use FaceTime or only in your home WiFi network? If it happens with your home network, have you tried power cycling your router? Unplug it for about 30 seconds and then plug it back in.
Turn WiFi off and on in the settings. Reset the network settings.
Have you tried any troubleshooting steps at all?

you will have to configure the express to create a wireless network but you do not need a connection to the internet.

Why does my iBookPro drop its WiFi connection so often?

My question: why does my iBookPro drop it WiFi connection so often, and what can I do to prevent it (or at least extend the duration of active connection)?
I have an iBookPro running OSX 10.9.5, with a 2.4 GHz Intel Core i5 processor and 8 GB 1600 MHz DDR3 RAM. I think my iBookPro is about 3 or 4 years old.
What seems to happen is that I will use my iBookPro accessing mail & websites for a few minutes, and then when I try to send an e-mail, mail puts up a message that it cannot send mail with the selected server, so I need to either try a different server or try later. Meanwhile I notice that the WiFi signal indicator shows full service, but when I run diagnostics it shows that the internet is not connected. Opening the WiFi icon in the top menu bar shows that it is looking for Networks. After an indeterminate time it finds the network I have had highlighted and logged into (my WiFi -5G router) since I opened my iBook when I arrived at my office.
I often find I have to turn WiFi off, then back on, to get connection with the internet.
What's going on, and what am I missing?

Hello jBookProAm,
If you are having issues with your MacBook Pro with maintaining a Wi-Fi connection, then take a look at the articles below to get it sorted out. The first article will talk about using Wireless Diagnostics, which you have already done, but also you look at the additional troubleshooting within the article for assistance. You may want to also create a new location as another troubleshooting option and those steps are in the second article.
