My iMac loses its wireless connection repeatedly

My iMac loses it's wireless connection repeatedly. The only solution seems to be deleteing the wireless network from the Network Preferences, and then deleting the network password from Keychain. But I have to do this five or six times nightly. Help!

Softwre Update would bring you up to 10.7.4 and there have been updates involving WiFi. Also here are some links to potential fixes:

Wireless Improvements
Move the Base Station If interference is particularly bad in one part of your house or office, move the base station to another location. But this can be tricky if your AirPort base station has to connect to the broadband feed coming into the house and that feed happens to enter at a particularly interference-prone spot.
Use the 5GHz Band Compared with the 2.4GHz band, the 5GHz band is practically empty. The newest AirPort Extreme Base Station is one of the few Wi-Fi base stations designed for home use that work in that 5GHz band. All of Apple’s Core 2 Duo laptops and iMacs (except the discontinued 17-inch 1.87GHz model) can also use the 5GHz band; with the build-to-order wireless option, so can the Mac Pro.
To switch to the 5GHz band, launch AirPort Utility, select your base station, and switch to Manual Setup. Click on the AirPort button and select the Wireless tab. Select 802.11n Only (5 GHz) from the Radio Mode pop-up menu. Click on the Wireless Options button and select Use Wide Channels. Click on Update to restart the base station.
Currently, no Mac-compatible adapters enable you to use the 5GHz band in older Macs or with older versions of OS X.
These Firmware updates may or may not apply to your system, but may help with your particular problem.

My brand new iMac loses its WiFi connection when it goes to sleep, does anyone have a proven fix?.

I have a MacBook that is about 4 years old and a brand new iMac both are running the most up to date version of Lion. My old MacBook has no issues; however, my iMac loses its WiFi connection every time it goes to sleep. There are some discussions about this already out there but does anyone have a proven fix. This is very frustrating.

I was having the same problem for a long time. I tried everything but nothing seemed to make it stay connected. It was very frustrating. I just got a new Airport Extreme.....bang!.....all better. Problem gone.

MY HP desktop computer totally loses its wireless ability each day plus its unresponsive

I have HP model #HPE-150f which 8 gb of memory. In reality this computer should be a beast and be quick as heck. However its the slowest machine I have ever used. I just had it looked at by a computer expert. He scanned and cleaned everything u and didnt see anything wrong with it. First of all it constantly loses its wireless icon. Its weird I can do a search and nowhere can it be found. However usually when I restart the computer it shows up again at the bottom right of the screen.Why would this disappear all the time? Why when it is currently not to be found that when I seach wireless access it only says things about an ethernet cable and absolutely nothing about a wireless card?? Very confusing!
Second with all the memory in this computer and it being an i7 processor why is this computer so slow? Why does it hang all the time and then freeze? All we use the computer for is surfing the internet and watching tv shows?
Homestly I ask my daughter why anyone would put up with a lousy machine like this when my 4 year old Apple Imac works so fast and smooth and NEVER have any operting problems??
Come on HP there must be something wrong with this expensive paperweight!

jmbeam,
Seems like a contradiction.
Can you turn off the system, and remove the power cord?
I would like you to look inside, and verify the antenna is attached to the card.
What type of internet do you have? and what speed. Test here

Satelite C660 keeps losing its wireless connection

Hi
We have bought the above laptop for our son for christmas and it keeps losing its wireless connection, we also have a Satelite L450 which is running fine (not losing internet connection) we have been onto our broadband supplier they have told us that as the wireless connection on our other laptop is fine, it is something to do with the C660, one of the drivers needs an update, unfortuneately I have forgotten the driver name but it is something to do with the modem, Our son is desperate to use his laptop.
Can anyone help?

Had the same problem but with a different Satellite model - the signal was fine on another laptop in the room - the problem was the power management option / power plan - the link below says it all but in short if it is on balanced the default option the default means that it tells the router to go into a power save mode that it might not support.

Have a read, hope it helps as it worked for me and is a very simple solution!

How do I keep my Ipad from dropping its wireless connection?

How do I keep my Ipad from dropping its wireless connection?
Most of the time, my iPad does not maintain a connection to the interenet via my wifi router. My PC laptop has continuous connection, so I know it is not the internet connection.
Is there a way to trouble shoot this? Can I purchase a dedicated IP Address for my Ipad? This is beyond aggrevating since internet activity is the main reason I purchased the pad.
Your help is greatly appreciated.

I would suggest that you give Apple Tech Support a call and go over your settings under WI-FI and General Settings as well as your router settings etc.. There are all sorts of things I could tell you to try but this forum is not the best place to go over all the numerous settings that could be the issue. Just call them and they will walk you through the proper trouble shooting steps.

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!

HP Photosmart 7510 occasionally loses its wireless settings

I have a HP Photosmart 7510 which occasionally loses its WPA-PSK secret and manually set IP address.
To solve the problem I have to re-enter the SSID's WPA-PSK secret and set the manual IP address (I prefer having the printer on a specific IP address).
To my knowledge the printer has not been powered down and there were no power failure - though I would expect these values to have been stored in non-volatile memory.
Is this a known issue?
If so is there a firmware fix - currently running VEP1CN1137CR(113730)

I can assure you that it is not a router issue. It appears to me that it is a driver compatibility with Windows OS. After trying to get to the bottom of this since my Photosmart 7525 was new and reading just about every forum and blog, I have come to the conclusion that the issue must be related to the HP driver itself.
The issue does not seem to affect any Mac systems, and from one forum someone was able to fix it by downloading new drivers compatible with 64-bit systems (which seem to not be affected by the glitch). But that leaves us 32-bit people stuck with the current driver which does not work.
The printer is connected with good signal to the wireless router (no matter who's router it is and what configuration is made). The printer can be pinged from the router and any computer on the network which is not currently being affected by this issue. However, the affected computer fails pings by either request timed out, or destination host unreachable. Pings are successful from the affected computer to any other device on the network. The only way to recover (at least for a few days) is to reboot the affected computer.
Also, from the display on the 7525, the network tests pass without issue. I can also download and print content from the internet with no issues.
Please do a quick google search of this issue and you will see several THOUSAND entries of people with the same request. This is a serious issue that people are having and everything is pointing to an HP problem (not routers, improper installation of software or drivers, etc...). I agree with several other customers that HP should be on the hook for this fix. I will give it another couple weeks, then back to the store for a reliable unit from another competitor (Canon, Lexmark, etc..)
Thank you in advance for escalating this issue to product engineering,
S. Hunn

IMac-stereo system wireless connection?

Suggestions wanted, please, for wireless connection of IMac with Airport Extreme card and/or Bluetooth to older stereo system in other room to play ITunes/Internet-accessed radio stations.

Do you know whether it can be used simultaneously with other tasks, such as printing wirelessly via Airport and browsing? I could never print without switching off Internet access in order to connect to my printer.
Yes, the AX can be configured in several ways, including a remote base station in a Wireless Distribution System (WDS). In a WDS, the AX would both extend your current AEBSn's wireless network and provide a means to stream iTunes and/or share a USB printer concurrently.
Where is a good guide to all these connectivity issues?
There are several good ones at the following link: Apple Manuals

My computer keeps losing its wireless connection

I have a second gen Airport Express connected to a DSL modem; my main computer is a Mini, late 2012 model, running Mountain Lion on 8 gb ram. On this network, I normally also connect a MacBook running Leopard, and iPad and an iPhone.
The Apple Airport Express model is not the newest, it is A1264 54 Mbps Wireless N Router (MB321LL/A). I've been using it about 2 ½ years without problems.
Just recently, however, my Mini has stopped holding on to the connection. At first, I figured it was a network issue, but I've done' some trouble shooting and find that is not the case. The network is fine when I plug ethernet direct from the modem into my computer, and I have even gone so far as to set my computer up as the wireless point of connection for the other devices, and the connection speed makes me think that the wireless card in the computer is operating just fine.
When the Airport is the wireless connection point, all the other devices have no problems, but the Mini is just awful; I have found after considerable frustration that when a page fails to load or another call to the network fails to execute, I can mouse-click the wireless symbol on the menu bar and see that the Wi-Fi is "looking for Networks," and after a brief pause with the spinning wheel animation, it finds my network in the list and turns itself on.
Forgive me, but WTH? I suspect this is something fairly simple, a setting, but what? I was all set to buy a new Airport Express, but I really don't want to if this is something fixable.
Does anyone know what's going on here?
I can tell you that the modem is set to "bridge" mode. After 10 years, the modem was replaced about a year ago, but I've had this setup for about 11 years, DSL in to a DSL modem to wireless router (always the original Apple Airport Base Station or an Airport Express, I've cooked a couple over the years).

Thanks, that may put me closer to a fix, but I'm not there yet.
I'm not sure I made it clear, what's happening is the WiFi grip on the internet hangs and then drops. I have learned that when the browser progress bar halts or a podcast download slows to a crawl, I can click the WiFi icon on the top menu and it will sometimes goose the network back to a secure connection and the task will complete; other times it drops entirely, forcing me to restart everything.
I have now ordered a new Airport Express, but won't have it until the week-end. I will then have 3 months of phone support. I was shocked to find Apple has raised the price for phone support, and while I did get a little free help yesterday, all the woman really did was get me to buy new stuff. I can't afford this. And I will bet that the new router will not solve the problem.
I am trying to use the Wireless Diagnostics app to get some idea of what is causing the connection to hang and fail. The Apple support person did not suggest this, but I am using the utilities feature to actually watch the connection struggle and then drop; I then generate a WiFi report and try to see what was happening when the failure occurred.
Sometimes these drops are temporary, and sometimes they require a modem and router re-start.
The problem is, I have no idea what these reports mean. I have tried to read the instructions, and I'm not doing very well at that. AFAICT, there is no problem with any of my settings. Other devices on the network do not lose connection the way the mini does. I don't use any location settings. so that's not applicable. I have gone over the "best practices" list and think I'm in compliance with all the recommendations. It seems odd to me that the Apple page [About Wireless Diagnostics - Apple Support] tells the user what's in the diagnostics report, but does not mention what to do with the information, how to understand it or use it. I have been watching the performance graph, and sure enough, when the connection fails, the graph reflects the failure. It operates in the excellent range most of the time, or slips into the "good" range, but I have not seen it in the poor range, it just drops. Then the Airport Untility shows the router with a yellow triangle sign with an exclamation point in the middle.
I can post the WiFi logs if anyone can understand them.

IMAC/VERIZON DSL wireless connection

Has anyone been able to connect "wireless" an IMAC-24 (intel) with Verizon's DSL?
Mac OS X (10.4.8) XP - 2000 - NT
Imac 24 - Intel Core 2 Duo Mac OS X (10.4.8) XP - 2000 - NT

Thanks Donald, but I should had been more specific.
My equipment:
My Apple is an Imac-24 Intel Core 2 Duo with an Airport Extreme card w/ firmware version 4.80.76.1.
I network a Toshiba laptop w/MS XP using an Atheros AR5001+ wireless card, a couple of generic Intel PC w/MS XP using an Ethernet cable connections, A USB D-link print server using Ethernet cable.
My ISP is Verizon and the connection type is DSL.
Verizon provided me with a modem/router combo to use - a Westell VersaLink model 327W. This device is a specifically made for Verizon by Westell, thus Westell will not even talk to me.
The Problem:
I can not connect wireless my Imac to the network.
My Apple Airport is able to find the network and it makes it available for connection. When I try to connect I get the following message: "There was an error joining the AirPort network 'nameofmynetwork'." Can there be a more useless message?
Background:
All computers, ethernet and wireless, except for the Imac Wireless, connect and function properly. Thus, reasonably, I can eliminate a hardware problem with the possible exception of the Airport Card malfunctioning, but I doubt it since it seems to be recognizing my network. I don't have access to another AP (access Point) device to fully eliminate the AirPort Card from being the problem.
Not that it really matters, but an ethernet connect to my Apple works well.
The Westell only uses the Wire Equivalent Privacy (WEP) scheme. I understand the problem with this scheme in which, unfortunately, it wasn't very standarized and hashing of passwords could occur among devices from different vendors producing non-matching encryption. I have tried all kinds of combinations open, shared, 64, 128, hex, ascii, and I even reconfigured my network to be totally unsecure (Eliminated password, mac table, etc, etc.) but I still can not connect.
I have called Apple, Verizon, Westell and exhausted the capabilities of their "technical support" - that is, we went through their entire "Scripted" Q&A system without a solution, and I could never get them to scalate my problem to a real tech person. - They are all pointing the finger at each other, except for Westell who basically said: "NO MY PROBLEM! We build this device specifically for Verizon and we provide no support"
I went to the local store and spoke with the resident guru but, all he tried to impress on me was how complicated networking was. To that I left, I couldn't take it anymore, I am not looking for a network guru, just someone who knows what are the parameters I should use so that that the Apple's version of the Airport Extreme can communicate with Verizon-Westell VersaLink 327W or that maybe can confirm that this two things will never talk to each other.
To anyone reading the above, I apologize if sounded cranky.

Nokia 5800 - Loses the wireless connection

Hello.
I have a Nokia 5800 cellphone from a week ago.
I have a problem with the WIFI (Wireless connection).
If I connect to a WIFI, in approximately 5 minutes the connection hangs, losing the connection. It seems random hangs.
It happens in all applications, and I have to connect again.
I tried with several different connections (WIFIs), and the same result.
Sometimes it stays connected longer, but generally falls.
Anybody know it can be, and the solution?
Thank you very much.

I have had this happen as well sitting right across from my router. Can be working fine and then all of a sudden kicks me out to the home screen. Since there is no connection failure message I have to conclude that it is a random bug, possibly with the built in browser. I have not tested this with Opera Mini yet to see if it is hardware or software related.
If I have helped you with your problem in some way, please take a little time and hit the kudos button in my post. Without your feedback, I don't know if I am being helpful or should just be put out to pasture.

HT4628 My iMac loses its connection with my home wi-fi network when it goes into "idle" mode. That is, if I don't use the Mac for a few minutes, it goes to idle, kind of like sleep. The wi-fi connection disappears and the clock upper right stops working.

I think it's a Lion problem. I had this problem with an old Dell True Mobile wireless router, and hoped it would go away with a new Airport Express router. Same problem. I checked online and saw a lot of message boards featuring questions from people that suffered the interruption of their wi-fi connection, some with Macbooks others with iMacs like me. The problem happens when I don't use the computer for a few minutes. It goes into the Idle mode, kind of like sleep. The connection is severed and the time clock upper right stops. It's weird. There was supposedly an Apple update that addressed this issue, so at the Genius bar two days ago I updated to 10.7.3, downloaded and installed the update. Didn't work. Is it Lion? Is it a wireless card issue? Very frustrating. I subitted a genius bar work authorization with another Apple Genius Bar support tech the next day. He ran some tests. Cryptically said he knew that Apple knew about this and was working on a solution but couldn't tell me what it was. Submitted my info and said I'd be contacted by an Apple tech within 48 hours and provided with a link to another download of another update that should "fix" the problem. I don't know what to do.

I FINALLY SOLVED THIS ISSUE!!!!
New routers have "mixed" modes for your network; this means that it will automatically choose the best option between wireless-B, wireless-G and wireless-N network modes. I used to experience this issue using the 2.4 GHz. mixed mode wireless network.
Thankfully, my router can create 2 networks: a 2.4 GHz. network and a 5 GHz. network.
When I randomly changed this value to "use only wireless-B and wireless-G" trying to fix an issue with a wi-fi expander, the iMac wi-fi issue dissapeared! I tried it with wireless-N only, but it didn't work.
So, finally, I have a 2.4 GHz network with only wireless-B and wireless-G modes which works PERFECT with the iMac, and a 5 GHz. network with a mixed* wireless mode for everything else mode.
*PD: by "mixed" mode it means that the router will automatically choose between B, G and N network modes as it fits better.

Is there a way to get my iMac to restart automatically whenever it loses its WiFi connection?

It loses the connection more often than I'd like, a problem that can be remedied with a restart. However, when I'm away, I'm obviously not able to do that. This has made accessing my computer remotely rather difficult. I've searched for a solution, but haven't found any.
What I'm looking for is something I can activate before I leave that will restart the computer whenever it's dropped the connection or something that will restart the computer at regular intervals. If anyone can help, I'd really appreciate it.

Sorry, but that doesn't help me. I already knew that function existed and I use it to shut down my computer at a set time every night and start up at a set time every morning. Unless I can somehow make it restart multiple times per day, it's not useful, but thank you for trying.

ATV1 lost its wireless connection ability

After years of using my ATV1, it has lost the ability to connect to my wireless network. I have made zero changes to the network. It will connect to the internet/network if I use an ethernet cable. I'm guessing the wifi card in the ATV1 went bad but if anyone has any suggestions they would be greatly appreciated.

Sounds likely that the card or its connection is faulty. Could be an early symptom of more general hardware issue.
Apple are unlikely to be able to offer repair. From memory I suspect the wifi card is replacable if you could source another (one of the unofficial modification groups dsabbled with swapping a 'video processing' card for it sacrificing wifi but allowing HD decoding).
If ethernet is impractical I'd highly recommend some mains powerline network adapters (my personal preference being those from Devolo - I've had '200 Mbps' rated ones for a few years and am thinking of getting newer '500 Mbps' ones - with all these products the ratings are theoretical and much lower in practice though cn be considerably more reliable than wi-fi.)

My mid-2010 iMac loses wi-fi connection randomly

It started with Lion installation. System couldn't reconnect after wake-up from sleep. After installing Wi-Fi update 1.0 for iMac it reconnects fine after sleep. But meanwhile problem with randomly disconnecting wi-fi appeared.
My router and its settings is fine because other apple products connect and maintain connection flawlessly (iPad, iPhone 3GS, iPhone 4, Macbook Air, Macbook White).
Under Snow Leopard iMac worked fine.
Any fix for this?

I was having the same problem and could only get it back either by restarting iPad, clearing the network or restarting the Router. I eventually found this useful post on the Princeton Universty website:
http://www.net.princeton.edu/apple-ios/ipad-iphoneos32-dhcp-workaround.html
It appears the problem is caused if you have any applications which uses Push notifications such as Mail, Contacts, Games Centre etc. Apparently in IOS 4.3, when the iPad goes into sleep mode it should drop the wifi connection to clear the DHCP cache. If you have notifications on, it doesn't drop the connection on sleep so when it wakes up again, either the DHCP cache entry is out of date or something else is out of step with the router.
This only happened after an abortive attempt to upgrade to IOS 5.0.1 (see https://discussions.apple.com/message/16778153#16778153) and a downgrade to IOS 4.3 which I think is where Apple introduced the Games Centre with notifications turned on by default.
