MacBook keeps losing Airport connectability

It's an older Airport, a white 11g.
For no obvious reason, my MacBook will decide that it can't connect to the Airport. Reset doesn't help, nor does restarting the MacBook. Only deleting the current Airport connection settings in the Control Panel and making a fresh new on does it.
Other Macs and my iPod are usually able to connect when this happens, so I have to assume it's a problem in the MacBook, though I don't know what. Hoping someone here might have ideas.
I'm on OS 10.7.5, but have Tinkertool, so I'm able to make the Library visible if there's something in there I could stand to delete, a preference or something.
Appreciate any help you guys can offer - thanks.

It may not help but to answer your question about deleting a Preference file, drag the following two to the Desktop, or directly to the Trash, and then reconfigure your network preferences:
/Library/Preferences/SystemConfiguration/Preferences.plist
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
If you select either of the above lines (triple-click it) and then control-click (or right click, or two-finger tap) you can use the contextual menu to select Services > Reveal. The Finder will open with the file already selected. TinkerTool is not required to do this and I don't recommend using such third party system hacks in general. Though I believe it's unlikely, that could conceivably be the cause of this problem or others.
The reason deleting the .plist files may not help is that deleting your AirPort connection preferences alone should have been sufficient. Anything's possible though so let me know.

My macbook keeps losing wifi connection after restarting and I can't connect to my wifi in recovery mode

I have two problems actually, which I think are connected.
I installed a new hard drive and am in the process of returning my macbook pro to normal. I'm now using Mac OS X 10.6.8 and I want to be able to update to OS Lion.
When my computer is on it can connect to our wifi without any problems (so the password is working). However, everytime I restart, it looses the connection and does not automatically reconnect. This never happened before and I can't seem to figure out where I can change this. All I have to do to reconnect is go to the wifi symbol and choose our wifi code. It then automatically connects without me needing to type the access code.
The seconde problem is when trying to update to OS Lion, when in recovery mode, all I get is a screen asking me to connect to wifi. I choose our wifi and now I do have to type a password, but whatever I do, it does not accept the code. It has nothing to do with capslock or anything like that.
We are sharing our wifi with our neighbour, so changing the password is not an option. But is is just a simple letters and numbers password.

Why not do a "Restore" in iTunes to set it back to factory settings? That will eliminate any previous information that is causing you issues in use. You will have an iPod which you can sync as if it is new with your settings and info.

MacBook Pro losing WiFi connection. Problem with AirPort Card

My MacBook Pro keeps losing Wifi connection. Sometimes it says no AirPort Card is installed. It has also been freezing, and the only solution is to hold the power button to turn it off. Then I have to restart the computer, but everything I was working on is lost.
Any ideas what is wrong or how to fix?

Sounds like your WiFi chip is going bad. Have you gotten it checked by an Apple Store rep ?
Have you deleted the contents of /Library/Preferences/SystemConfiguration, rebooted and tried ?

My iMac keeps losing the connection to my chosen Airport Wi-Fi network. Anyone know why this happens?

Close all Apps and see if Activity Monitor shows any processes runnung.
Not that I think this is the cure but have you tried these resets:
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
The 5 second timing is important to a successful reset.
PRAM RESET
Zap the PRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

I have a Airport Extreme 802.11n and my T.V. is a panisonic,I keep losing the connection. Anybody have any answers?

Plenty of suggestions.. only you can find out which one is correct.
What model AE? What firmware?
Since Panasonic TV is not apple it will use SMB windows type networking.. everything but Apple does.
Are the names in the AE all SMB compatible.. ie short.. max about 20 characters.. no spaces and pure alphanumeric.
Is the security set to WPA2 Personal with a pure alphanumeric password of 10-20 characters.. more is fine if you suffer paranoia but isn't needed.
Fix the wireless channels.. so it doesn't flip flop like a dying fish.
There are only 3 channels for 2.4ghz that do not overlap, 11, 6, 1 although someone suggested 8 works well if you have heaps of interference. If you live in flat/apartment building you have heaps of interference.
Lastly is it stable if the distance is 3M direct line of sight?
If not then get a high power wireless AP and use that instead.

IMac keeps losing network connection

My iMac keeps losing the connection to my AirPort very sporadically, but very often. I keep having to open Network Assistant, choose the AirPort and the network, and re-enter the password. I then get a message that my network connection appears to be working correctly, which it then is. This could happen several times in a few hours.
I have tried creating a new network, but it still happens. We have 6 other devices on this network and do not have a problem with those devices.
Any advice?

What am I looking for in the window that pops up?
here's a (very crude) screen shot of an iStumbler scan on my MBP
my network is called pegasus. see that it broadcasts on channel 11 (2.4 GHz band) ? see also that there are six other networks broadcasting on the same channel ? now, ideally i would change my channel to broadcast on "5" or "6", but since there are so many networks around, even those would give me interference from other networks nearby.
in the end, i decided to hardwire (using ethernet cables) most of my devices to my router (time capsule) in order to avoid interference alltogether.
also, there could be closed (hidden) networks around that only KisMac would be able to pick up.
lastly, as the read about *wireless interference* revealed, there are other sources that could interfere with your network performance: microwave ovens, cordless phones - heck, even enabling bluetooth on your very own Mac could be a source.
as an alternative to running ethernet cables throughout your place, you could consider *powerline adapters* _*such as these*_.

Macbook keeps dropping wireless connection

Hi
this is my first post so be gentle with me LOL
I have had many issues with BT over the last 8 months, mostly due to the speed I had in my area (was 0.45MB when wired at one point), but I recently started to have an issue with the laptops in the house.
I have 2 teenagers and luckily for them we all have Macbooks as I have given them my old ones when I have upgraded I am using a macbook pro (less than a year old & wireless N) and my eldest boy is using a Macbook (about 6 years old with wireless G) you might see where I'm going here....
the problem is the older macbook keeps losing connection on the wireless, I have called and spoken to the 1st line support guys in India but it's a bit of luck if you can understand them let alone find someone who knows what they are doing. As I work in IT I completely understand and normally ask them to read my notes before advising me especially as I had so many issues last year when I was given a number to get through to the priority care team LOL , so far I have tried the following:
moving the Hub 3 to several locations around the house
reinstalling snow leopard
using a wireless dongle
I live in the middle of nowhere so there are no other houses around which have a hub3 sp none can be affecting me and I've checked this by using programs like inSIDDer.
Finally I thought I'd take it to work to see if I could get the model number of the wireless card and order a new one and guess what it works fine!! So I thought I'd check at a friends and again it works fine for the whole time I'm there.
Brought it home and it won't stay connected GRRRAAA!!!!!!!
I've heard that the hub3 doesn't like having a wireless N & and wireless G laptops on the connecting at the same time is this correct? Has anyone else heard of this?
finnally I do have windows machines in the house and none of them (2 laptops and a desktop which is wired) are having an issue but the Sony TV which is wired directly in to the hub will also drop connection randomly between 8 PM and 10 PM every day so I'm leaning towards the hub being a rubbish router instead of the problem lying with my Macbook

MacBook keeps dropping Airport signal

My new MacBook keep loosing ist connection with the AirPort Express.....i'm not sure if its the Express or the MacBook....there is only a few feet of distance between the two and all updates have been added to the MacBook. After 3 bad Pro's and one bad MacBook I really want to keep this unit and any help you guys could give me would be great.....i'm a new mac user. Cheers.

I had the same issue with my new MacBook and thought it was the notebook.
Here's my story: I went back to the Apple Store where I bought my macbook and told them that there is something wrong with my AirPort card inside the macbook that is "defective" because it kept dropping signals. I would get a connection for a few minutes or seconds and then lose the signal the next! The manager had NO CLUE why that was happening and asked that I show proof by reproducing it inside their Apple Store! I told the manager I would like a new one and she was nice enough to exchange it for me at no cost.
After doing my own research, I discovered that the problem was not with my MacBook, but rather it was with my Linksys wireless DSL router. Luckily, all I had to do was update the firmware on the Linksys DSL router and....I have not lost signal since!
My suggestion is to update the firmware of your router (e.g. Linksys, Belkin, D-Link, etc. All I had to do was go to Linksys' website and download the updates and run it through my router system) and see if that fixes the problem. Good luck!

My apple tv keeps losing the connection to iTunes.

apple tv keeps losing the connection to itunes

Hi I have all my appletvs set to NEVER SLEEP - go to your appletv settings/general/sleep after and choose never sleep. Since doing that I have had no problem with them. Also I leave my 2010 macbook pro running itunes and permanently on and open - it is my main homesharing disk. I give it a sleep every now and then when not using appletv.
Try that first anyway.

Can't re-order my queue on Netflix and keep losing the connection

I'm having so much trouble with Netflix! I can't re-order my queue, I keep losing the connection, and it's painfully slow. Is Netflix known to be unstable on iPad? Other internet connecitons seem to be fine.

I rarely have problems on it - I do occasionally have drops in video quality, but nothing consistent. It does require a very strong and stable network connection, and I also wonder if they have periodic "crush time" incidents on their end, considering the rapid growth of Netflix streaming.
Updating the queue is a pain on it - you can't do it on the app, and have to go to their website. I generally find it easier to do on a computer.

I upgraded Lion recently to 10.7.3. Since that time I am having trouble with my wireless connection. All other devices are fine, but I keep losing the connection since the upgrade.

Recently I upgraded Lion to 10.7.3. Since that time I have been having a lot of trouble with my internet connection. I keep losing the connect and have to go to diagnostics and turn it back on. Is anyone else having this problem?
Thanks, Pat

I'm afraid there are numerous threads on here discussing this problem. I posted in this one earlier that has a couple of suggestions, but the real solution will hopefully be provided in an update from Apple:

Macbook keeps losing Flashplayer.

Just recently, for no apparent reason, my Macbook keeps
losing/uninstalling the Flashplayer.
I can be using it as normal, leave the page/site/browser and
when I come back to it it fails, there is just the question mark. I
then have to reinstall from the flashplayer icon and all is
OK....until the next time. All macbook updates are installed and
everything else is working OK.
Any ideas as to what is happening and how to cure it ?
Cheers and thanks

Dare I say all MacBook Pro users are having this same
freaking problem?????  I have the question mark all day
in my line of work.  I actually have to jump on a windows
based computer to view webpages I upload and cannot view on MY
computer!!
Is there anyone out there who has an answer to the MacBook
Pro dilemma?
I see windows has Darren on their side.  What about
Mac people?  left in the dust? we have been here since
day one.
Haven't had a problem like this on any of my Macs in 15
years.

Do they have plans to fix the bugs with Yosemite. I keep losing internet connection on my Mac Book

Ever since i installed Yosemite on my Mac Book pro i keep losing internet connection. Should I go back to mavericks because I just hate this Yosemite or do they plan to fix the bugs soon? I did a complete clean install and I am still having problems. I see a lot of complicated solutions and I am not that tech savvy to go into my settings. Thanks

All software has bugs. The first release (which you have) will be the worst.
Many advocate not upgrading to a new operating system until it's been out for 3 months or longer. In the Windows world many recommend not upgrading until a full year has passed.
So yes, most / some bugs and glitches will get fixed over time. If you wish to reduce your difficulties in the future wait a while before installing ANY new OS.
I suggest you post specific details on your Internet problems. How are you connected etc.
