Why am i kicked out of my wireless network everytime my computer sleeps or shuts down?

why am i kicked out of my wireless network every time there the machine goes to sleep or when i shut the computer off. is there a setting where i can stay logged-in to my wireless network without having to select it every time?
Running Lion 10.7.5
very frustrating.
i hope the solution is not to buy Mountain Lion. that would make me angry.
thanks for your support.

Since it's a new machine, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine. That also might apply to newly bought ones inside the first 90 days.
FWIW, IMO, the AppleCare extended plan's the cheapest insurance you can get for your new desktop machine.

I get booted from my own wireless network whenever my computer sleeps

I just purchased a MacBook and connected it to my already existing wireles network. It works great, but my wife's ibook G4 keeps kicking her off the wireless network whenever her computer sleeps. This never hapened before, but seemed to coincide with my connecting my new MacBook to the network. To reconnect, all she has to do is to select our network from the list that pops up, but that gets annoying if you have to do it every time. Any help?

I too continually get booted, but not even when going to sleep. After a certain period of time, my Powerbook G4 disconnects from my Aiport. AND, everytime I start up, I have to manually select my Airport - it keeps wanting to connect me to the neighbors Linksys first. I have to say "no do not add Linksys to my preferred networks", then I have to manually select my Airport.
How do I stay connected to my PREFERRED network?

W510 Wireless Adapter: getting kicked out of most wireless networks

Hi Everyone,
I'm running a W510 with Windows 8 on it. I have an extremely annoying issue with my wi-fi network network card and I have no clue where it's coming from.
The wi-fi networks at my home and office work perfect and I haven't had a single issue with them. I recently started travelling a lot and tried using wi-fi on various locations such as open wi-fi on airports, secured networks in hotels, cafes, guest homes etc. Most of them are not workable. Here's what's happening:
I can usually connect the first time I try, but after a few minutes, and hour top I get kicked out of the network or end up with "Limited" access. When I try to reconnect the it goes into and endless "connecting" state. Trying to disconnect hangs the pane and no actions are possible until I:
1. Restart the explorer.exe process, which it "Not responding"
2. Disable and Enable the wireless adapter though the Device Manager
After that in case of some networks I can connect again for a few minutes, but then I all repeats all over OR I cannot connect back at all.
I have tried using A LOT of networks in various places, and I'd say with about 80-85% I experience the described issue.
I case of some of the networks I had a chance to connect by wire and they were working perfectly. Often I have other people around with me and of course I'm the only one facing the issue, it's not that I have really back luck for wi-fi networks. Plus my phone connects to majority of them without issue.
In many cases when I switch networks I need to manually run ipconfig /renew and ipconfig /flushdns, before being able to connect to anything.
The wifi adapter is a Intel Centrino Ultimate-N 6300 AGN on a Lenovo W510. The driver version is 14.2.1.3. I've seen 15.x version available for download from both Intel and Lenovo sites, but when trying to install it I got info, that I already have a newer version of the driver.
Uninstalling the driver and letting windows reinstall it does not solve the issue.
I ran out of options on what to check and how to debug this further. What are your thoughts on this?
Thanks,
MikeZyc

Hi, MikeZyc
I've seen this issue on many machines running Windows 8 with Intel wireless adapters. One fix that has worked more often than not is to navigate to Control Panel ► Programs and Features and uninstall the Intel Management Engine Driver. This driver seems to cause the wireless connectivity to get lost or not connect at all in Windows 8. Try uninstalling that, then restarting the computer and see if any improvement is made.
Best of luck,
Adam

Why can't I connect to my wireless network?

Why can't I connect to my wireless network? My phone is set to it but I can't connect with my ipod touch. Do I need to reset my wireless?

- Reset the iPOd. Nothing will be lost
- Power off and then back on your router

My MBP doesn't remember my Time Capsule wireless network when waking from sleep

My MBP (OS 10.5.8) doesn't remember my Time Capsule wireless network when waking from sleep. Thus, every time my MBP wakes from sleep, I need to select the Airport icon in the upper menu bar, select "Join other network", enter SSID and password. This is very cumbersome. And, I never had this problem when I was using the ISP's provided wireless router/gateway/DSL modem. Adding the Time Capsule and using it to generate the wireless network has introduced this problem.
It appears that this problem has to do with the hidden SSID. I don't need the lecture on how hidden SSID provides no serious security benefit. That's why I have the WPA2 encryption. I'm interested in a solution that will allow the Time Capsule to generate the wireless network, maintain a hidden SSID, continue to use WPA2 encryption, but have my MBP recognzie and autoconnect to this network.
Solutions I've alread tried:
1. Open Network Preferences
2. Select Airport from left hand column (and ensure Airport is at top of that list)
3. Select Advanced
4. Delete all Preferred Networks.
5. Apply settings.
6. Restart computer
7. Return to Network Preferences and from Advanced page, manually add my network with hidden SSID and WPA2 password
This solution works fine as long as I don't take my computer elsewhere and connect to another network. As soon as my preferred networks list gets another network, my MBP stops finding my TC network. Since I take my laptop to a lot of places (it's a laptop, after all...) this is a problem.
As I say, prior to adding the TC on my network (and using it to generate the wireless network), my MBP had no problem keeping 50+ preferred network names/passwords in the Preferred Network list, but always automatically finding/connecting to my home network without the need to "Join other network." Thus, I assume the problem lies with the Time Capsule.
Any ideas?

LaPastenague, thanks for weighing in. Didn't know that the hidden SSID capability was not IEEE standardized, and thus different devices will handle hidden SSID differently. With my admittedly limited knowledge of how SSID/hidden SSID works, I'm still a little confused as to why my MBP would remember the generic router/gateway's hidden network, but struggle with the TC's hidden network.
To my knowledge, when an SSID is broadcast by a base station (Airport, wireless gateway, etc.), a connecting device (like a laptop, iPad, etc.) detects this broadcast--this would be a passive reception of this SSID signal.
When an SSID is hidden, the base station does not broadcast its identification. Rather, a connecting device must transmit the name, and when the base station recognizes the broadcast, the connection is made. That's what you do when you select "Join another network" and manually enter the SSID.
The idea with OS X's Network Preferences is that these steps, whether for hidden networks or broadcast SSIDs, become automated.
Where is the potential for a different chipset between the TC and the previously used wireless router/gateway to alter this functionality? Shouldn't the selection of an SSID by the MBP to broadcast to seek for a base station be a function solely on the MBP? And once broadcast by the MBP, the TC should detect and reply?
Basically, the MBP can connect to the hidden TC manually just fine. The MBP can connect to the old setup automatically just fine. The MBP cannot connect to the TC automatically. Aren't these automatic connection functions solely on the MBP?
I'll try un-hiding the network and re-verifying that the problem is exclusively with the hidden network.

My MAC mini looses the wi-fi connection to a Belkin N wireless router when it goes to sleep or shut down. I have to re select the network when restarting or waking the computer up. I think this just started with Lion. My iPod and iPad have no trouble.

My MAC MINI looses the wi-fi connection to a Belkin N wireless router when it goes to sleep or shuts down. I have to re select the network when re starting or waking up the computer. I think this just started with LION. My iPod and iPad have no problem remembering the wireless network.

Thank you BGreg. That is what I have been doing, and then it works just fine. I think it was doing the same thing in the previous version of Lion. I may be incorrect about that. I upgraded to 10.7.3 a few weeks ago, and then last week I reloaded the combo update, hoping it would help. Not so. Thank you for letting me know it is a common problem. I have tried permissions in Disk Utilities, and in Macaroni, both at least 4 times, plus numerous restarts. Nothing Improves. It still can not find the internet when it wakes up or gets up.

Why was I kicked out of my FireFox Sync and asked to change my password?

I logged into my Desktop PC and found that I had been kicked out of my FireFox Sync account. The strange thing is I don't recall changing my password, in fact I had to log in with my laptop and change the password and then link the desktop and laptop again. I had not turned that PC on in a week or two.
Was my account just used by someone else and they changed the password or did something else happen? Please help, I am worried. This occurred about a week or two ago and I didn't make a screenshot of it.

Type '''about:sync-log''' in the URL bar and hit Enter; on the device where you received that "password" message.
Review the date on the logs, and view the log which relates to the time that you received that message.

Why are all my devices acknowledging my wireless network through my time capsule, but only one is able to connect to the internet?

This started when I changed the port for cable modem access. If I shut everything down- router, MacBook, and iPhone and restart the router... the device I turn on first will connect to the internet. The second device will read the wireless network but if you attempt to connect to the internet- it states no internet connection is available. Is this a security feature I enabled unknowingly? Very frustrated.

You are using your TC in the wrong way.. in bridge and it has to be in router mode.
Simply make sure you connect SB5100 to the WAN port of the TC.
Go to the airport utility, manual setup, internet tab on the bottom and choose connection.. ethernet.. and down the bottom connection sharing.. share a public IP.. sorry I don't have the exact wording as my TC is in pieces being fixed.
Update and then shut off everything again, particularly the modem.. start everything in order.. modem.. wait 2min.. then TC.. wait 2min then all the computers .. they will get an IP from the TC. With correct address and gateway.
What was happening is the first device to turn on was capturing the one and only public IP. The rest get local IP without connection.

Why does my powerbook suddenly not recognize wireless network-no connection

I did a software update yesterday (EFI Firmware Update, Bluetooth Firmware Update, Java for Mac OSX 10.5 Update 4, iPhoto Update, Safari, iTunes, HP Printers Drivers Update) and now, suddenly, my connection fails. The computer can't recognise my wireless network, while other computers in the house do. I dont know if it;s related to keychains, i've unlocked them, but nothing works. Help? Thank you.

FIXED!
The IP address of the printer had changed. I printed a new Configuration Page from the printer, which contains the IP address. I then entered the new IP address into my iMac. The iMac was then able to 'see' the printer and I can now print.
The HP forums solved this for me.

HP 8500A wireless printer can't find my wireless network (but my computer does) using DLink DIR 615.

HP 8500A Wireless All In One has been working fine for ages (minor occasional hickups), but now can't get it to print. Computer still picks up my wirelss network fine. Printer works on all other stand alone pieces. But, one day it stopped printing, so checked wireless signal. Tried all steps and reports (have done that once in past a year ago and reset fine), but still get error saying it "can't find my network"... HELP

Hello there @Rico6952 , welcome back!
I read about how your printer is not finding your wireless network and I wanted to stop in to see if I could help you. I have some suggestions that I would recommend for you to hopefully help. Check the links out below. They are all related to network connection problems.

Can't connect to any wireless network after waking from sleep

I have a Netgear wgr814 wireless router and a Powerbook 12" 867mhz. A few months ago, every once in a while when the PB awoke from sleep, it would not be able to connect to any wireless networks. My network showed in the airport menu, but the computer would not connect to it. I believe that the network settings show a self assigned IP of 169.x.x.x. Usually I can see 4 networks in the airport menu, but when it gets in this state only mine shows. Nothing I did on the computer side could make the computer reconnect: renew dhcp, restart, reseat airport card, etc.
After trial and error I found that if I restarted my router, the pb would reconnect and all would be well. The problem occurred about once a week for a while. Since resetting the router fixed the problem I thought that it may be my router so I updated the firmware. After doing so, the problem didn't occur for about a month, but now it happens at least once per day. Resetting the router always fixes the problem. I don't have to do anything to the PB. Once the router comes back up the PB obtains its IP and is happy again.
I'll mention that a Dell Laptop on the same network never has any issues and when the PB loses connection the Dell is always fine.
What could be doing this? My PB is over 3 years old, so is the airport card starting to die? That's the only thing I can think of.

hi there
alright.... I tried a bunch of things and I'm not exctly sure what I did that did the trick, but I got the problem solved. I turned off the WPA encryption on the AP. Then I turned it back on with a different password.
I wonder if the first password I had was too short and that was some how causing confusion.

Have to create wireless network everytime I boot up?

Hi
I have the 27" Quad core, if i create a wireless network and then switch off my iMac and use it the next day I have to recreate the network, but the odd thing is it doesnt do this every time, sometimes I turn it on and the wireless network is still there, any ideas in how to make the network permanent?
Thanks

HI and welcome to Apple Discussions...
Open System Preferences (Apple Menu) then select Network.
Select your network access on the left, Airport / Ethernet / Firewire then where you see: Network Name click the pop up menu and select the Network you created. Then click the padlock icon bottom left in the window to prevent further changes.

HT2712 How do I delete wireless networks that my computer keeps detecting?

My iMac keeps detecting other wireless networks in the neighborhood which slows down or prevents it from connecting to my wireless network. Is there a way to block those other networks?

Which is normal.

I'm not sure that it does. What makes you say that? It might be that the others are on the same wireless channel as yours with a very strong signal and are interfering?

Connecting to wireless network *and* another computer at the same time?

Hi,
I will be getting a new macbook soon and have an old powerbook with airport. I am wondering if it is possible to connect to my old powerbook via airport, while still being connected to a third-party wireless internet connection (from the macbook). The crucial point is that I cannot connect both computers to the wireless network, because subscription is based on the computer's hardware address and I don't want to pay for 2 computers (I don't need to have internet access on the old computer, just a connection between the two computers). Anyone knows?
Thanks!

What you are referring to is known as "Internet Sharing" for Macs, but it's typically restricted to sharing the Internet connection from one port (either AirPort or Ethernet) to the OTHER port...not AirPort-to-AirPort or Ethernet-to-Ethernet.
