OSX Lion WiFi Unreliable

I was using SnowLeopard before I installed Lion and I had absolutely no problems with the WiFi. My MacBook Pro is only a year old and had given me no problems at all. Then I installed Lion. Things were fine for about a week then I decided to reboot my machine. That's when the WiFi problems started. It would drop out after only a few minutes and the only way to get it running again was to reboot. I treid disabling the WiFi and rebooting the router but it just wouldn't work. I found a work around which was as follows:
1. Remove Wifi Config
2. Reboot Machine and Router
3. Reconfigure Wifi
4. Reboot machine and everything works
The problem is that if I reboot after getting WiFi working it will fail again and I'm back to square one.
I've been using Apple products since 2007 and I've never had any problems like this. I really can't understand why Apple would release a product with such serious flaws like this. I've also noticed a few crashes when in Email. This brought the whole machine down. Hopefully this will get sorted VERY SOON with a patch. Come on Apple, don't become another Microsoft!

I installed osx lion and now wifi led blinks constantly

I installed osx lion yesterday and now the wifi led on my modem blinks constantly
even when the mac is turned of.
Further on, in the left colum in finder there is under "Shared" a icon of a pc and written:
acer-13db0a52d9
I never seen this before.
I tried to open it but the only thing i could trace, was "NEIGHBORHOOD"..
Am I being Hacked?
Funny thing, is that this week I saw a guy in the street sitting in his car with a labtop.
What should I do?

Right click on the file and select get info. Click on the little padlock at the bottom and enter your password, change your user names permission to Read & Write. ( There will be a list of users at the bottom of the get info box with permissions which you can change.)

Mac OSX lion does not connect to wifi automatically

Hi there
My mac osx lion does not connct to wifi automatically , or when i open the lid it doesn't connect either...
could you please help me with this problem?

Bump
is there anyone else with a Mountain Lion Mac and a TP-Link TL-WDR4300? I am almost sure that it's this combination that doesn't work. All other devices I have (Apple and non-Apple) can work perfectly on 2.4Ghz and 5Ghz, but the settings on the WiFi adapter on the Mac are the same for all Wireless networks, so I just don't get why it would work on 5Ghz but not on 2.4Ghz...
Thank you

Intel SSD 320 Series Unreliability, Intel or OSX Lion at fault?

Hi,
I have been using the Intel SSD 320 Series 160Gb SSD in a Quad Core iMac for a couple of months.
Its was running fine all through the Lion Beta program, but Monday evening, my iMac with OSX Lion locked up and I had to power off the system (that never happens to my Mac normally).
On rebooting, I got the flashing folder with a question mark, signifying no devices with a valid OS were detected
The following morning, I had to replace the SSD with a 1TB platter drive and restore my system (thank god for Time Machine).
Disk Utility repoerts the SSD as 8.4Mb in size (no, thats not a typo) and thinks the drive is unformatted.
This is very disappointing, so much for hoping SSD would be more reliable than mechanical drives
I loved the speed of the SSD, but this type of failure whether its Intel's fault or OSX causing this catestrophic failure I am still unsure, but either way its totally un-acceptable and has made me wary of wanting to try again with SSD!
D.

To help future users searching, I have an update.
This appears to be a bug in the Intel 320 Series SSD drives which Intel have acknowledged.
I applaud them for owning up to the problem, but I am furious they let a product of this type get to market with a serious bug like this in the first place!!
If anyone is using one of these drives I suggest you make sure your Time Machine backups are running fine and are up-to-date and constantly check out the link below for a firmware update that at the time of writing has still not materialised.
Rest assured, you have a ticking time bomb on your hands!

any ideas ?

Your wifi problem sounds very much like the problem I had. The wifi would drop out, the icon showed it was still connected. If I turned it off, I couldn't turn it back on. Another user here pointed me to the problem, which was the wifi cable (the flat cable goint from the card to the motherboard). I found it on ebay for $13 and it's been running fine since I replaced it. This is the repair guide for your machine. The part number will be on there if you click the link.

Connection drop iMac to Apple TV - OSX Lion

Hello.
Hope someone might have a solution. Ever since i changed to OSX Lion i have had a really irritating bug with my Wifi. While browsing, downloading and doing everyday stuff my connection is fine.
However when streaming movies and tv-shows to my Apple TV (2nd) i have been getting som nasty connection drops. Its not always but to often to be anoying since i havnt had this problem before.
Scenario: I can start a movie and watch almost an hour when all of a sudden the connection drops on my iMac Late 2009 - OSX Lion 10.7.3. Everytime this happens my Wifi icon turns gray and i need to shut the Wifi off and turn it on again and all works. But once it has started the connection drops every 10 min or so and i need to reboot the machine to be able to watch the movie like "normal".
The connection between my Airport Express and the Apple TV is no problem and works flawless but my Mac cant seem to handle the "heat". I didnt have this issue on SL so im a bit bugged about it.
RSSI: -45
SPEED: 130
This is what ive tried.
1. Repair the permissions thru the OS, and the Command and R at start up, including the "resetpassword" thing.
2. Update firmware on my Aiport Express and downgraded since it just got worse.
3. Updated the airport utility, but needed to install back the old one since the new for Lion doesnt support the switch between 2.4 and 5.0 band.
4. Reset PRAM
5. Reset SMC
6. Rebuild the connection by deleteing and resetting the router.
7. Done some cleanup with OnyX.
Now im out of ideas since nothing seem to work and i hate that i have all this Apple gear for thousands of dollars and the f**** Wifi ruins everything.
Anyone?
Cheers
Chris

I have the same issue

IMac 27 inch i7 OSX Lion will not boot up from Hard Disc

iMac 27 inch i7 OSX Lion will not boot up from Hard Disc on cold start, and cannot find wifi hardware in the machine. Restart and everything is fine. I have two machine and they behave the same. Software or hardware problem?

First of all, try a hard restart; making sure no disks are in the slot, unplug everything from your computer (keyboards, mice, etc.) and then unplug the computer itself. Leave it unplugged for a minute or two, then plug it back in and boot it up.
If that fails, reboot it while holding down the option-key on your keyboard. The screen should show a choice of which disk drive to boot from. Choose your usual drive.
If that fails, reboot it while holding down the shift-key on your keyboard. It should take a while for it to boot up, as it is destroying all connections to sources that may contain a virus.
If that fails, reboot it while holding down keys "option-command-P-R" until you hear the startup tone a second time.
If that fails, reboot it while holding down the C-key. Make sure you have inserted the installation disk before doing this step.
If that fails, reboot it while holding down the command-key and the R-key.
If that fails, please reply to this and let me know.

Where can I get the Boot Disk for my macbook pro? Downloading OSX Lion is taking too long

I got a macbook pro that was owned by someone for a few days before. I tried to restore to factory setting but now downloading OSX Lion is taking forever with my internet connection. Can anyone help me find a boot Disk to speed up the process?

Apple no longer sells a Lion installation USB flash drive (they did at one time). SO you'll just have to wait for the download to complete. It's best to 'hard-wire' the download - not over wifi but with an Ethernet cable connected directly to your router. That will gain you some speed.
You could also try taking your MBP to a friend's home where they may have a faster Internet service. My download speed is 22+Mbps with my cable company - you may have a friend or neighbor who has something similar? Of course, you are always at the mercy of Apple's servers - sometimes they're just overloaded and a download that should take 20 minutes can take up to an hour and one-half.
Good luck,
Clinton

I can't download linked files on mac osx lion what do i do?

i can't download linked files on mac osx lion what do i do?

There have been some reported problems with Apple's servers.
Try this.
Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
I assume you are trying to update via wifi. You can also connect the iPad to your computer and update using iTunes.

OSX Lion and exporting for iPhone

There was a thread about how when trying to set and/or publish for iPhone or edit its settings, Flash CS5 immediately crashes. The problem has been experienced by many Mac OSX Lion users and they talked about it in this unresolved thread: http://forums.adobe.com/thread/888198#3851750 but still no updates from Adobe. Adobe sent me a response to my Support ticket that "it's an Actionscript 3 coding issue" then closed it so I couldn't reply. Ummmm, NO it isn't a coding issue, I tried to export an FLA file with no code in it. That's a really bad way to do business, Adobe. But since they're not going to be helpful (and probably lose me as a customer) has anyone else found a workaround for this?

The aspect ratio of the iphone screen is 480 x 320, but that size is not an option when exporting for iPhone using Compressor. You have to use a custom setting.
Why is this the case?
You have to understand that the Apple-provided presets are good launching points, not end-all, be-all settings.
And iPhones do support material encoded as 640 pixels wide so the preset for VGA (up to 640x480) works fine for most people. I personally rarely use anything smaller than the VGA setting for Apple Devices as I find that's the perfect middle ground for iPods, iPhones and AppleTV.
If you (understandably) need to limit your file and frame sizes, adjusting the device setting in Compressor to iPhone (Local/WiFi) does the trick - fitting your movie into a 480 pixel-wide frame size and capping the video data rate at 1000 Kbps.
Letterboxing - as in hard mattes - is not needed when encoding for Apple Devices. In fact, if you have letterboxing in your source media, use the Geometry pane to crop out the Letterbox Area of Source. That will provide you with a better quality encode and the preset will know to adjust your output frame size, so you need not worry about distorting your movie.

My epson sx525wd printer will not install/add to printer list on osx lion

I have recently installed osx lion on my macbook and imac and have had a few issues. the most frustrating one is using a new printer i bought, Epson sx525wd which i bought several months ago but hadnt got round to playing with it yet. Maybe my downfall in not installing on Snow Leopard prior to Lion intall.
Anyhow, When trying to add the printer in the printer system preferences panel, both usb connected or wifi, the message that appears is, this printer software is available to download from apple wound you like to download it, i click yes and it says there is not software to download and then wont let me add the printer.
So, i tried downloading the software/drivers and so on from epson, successfully and installed but add printer system preferences panel still asks me to download from software update and again says there isnt any software to download.
So, i tried doing a software update from the apple icon, software update. again no software updates available. Finally i found the CD installation disc that came with the printer thinking i had fool it. to my disappointment i found that the installation software on the disc was not working and said i needed to install rosetta. and to my further disappointment i discovered that lion has discontinued the use of rosetta.....? is this true.
I am unsure what to do...
would it be safe to say that i might have to revert back to snow leopard to install the printer then upgrade to lion again?
can anyone help or at least give suggestions?
Many thanks
Andy

Delete the /Library/Printers/Epson folder. Then try installing the software that you downloaded again. If that doesn't help, you can try downloading the full package of Epson drivers from http://support.apple.com/kb/DL900.
It shouldn't be necessary to go back to SL and then to Lion to get this working.
Hope this helps.

How do I uninstall OSX Lion

any bright people out there know how to uninstall OSX Lion off a macbook pro?

Sure.. reinstall from scratch is one approach.. but it's probably easier to fix the issues.
What's the problem?
Try repair permissons and restart. Try installing 10.7.3 Combo from your desktop. Try deleting "-" the wifi service in Systems Preferences/Network, and then recreate it "+". Then restart.

Mountain lion wifi, mountain lion wifi

Soy usuario de Mountain Lion en un ordenador macbook recién comprado y la conexión inalámbrica (airport), falla constantemente. Es un problema que ya tuve con un macbook del 2006 con OSX Lion, al que decidí reinstalarle Snow Leopard.
¿cuándo saldrá una actualización que resuelva el problema de pérdidas de conexión inalámbrica?
Gracias.

Creo que he corregido el problema.
El caso es que ni el Servicio Técnico de Apple, ni tampoco la compañía que me sirve internet, han conseguido solucionar el problema, pero hilando, hilando, hice lo siguiente y eliminé el problema:
- Entrar en la configuración del router-wifi/avanzado/Rate (o lo correspondiente).
- Normalmente, el ratio de descarga estará en auto, pero tenemos que limitarlo al máximo de Mb que tengamos contratados, ya que algunas compañías, al dedectar que hay más tráfico de datos del contratado, cortan la conexión. Por ej, si tienes contratados 5 Mb, pues pones el ratio en la cantidad máxima posible, para que no te sobrepase ese tope de ratio.
y ya está, problema solucionado.

? about osx lion

Ok im a newbe on here, but have owned macs for years. (once you go mac you never go back) my question is if i buy the download of osx lion from itunes for my wifes macbook pro running 10.6.8 sno leaopard,as wll as mine can i use the same download to load lion on my mac and if so how do i transfer it to mine

Lion is in the Mac App Store, not iTunes, just to clarify. Yes you can download it on both, just sign in to the Mac App Store on both computers using the same Apple ID. If you have alreadfy purchased it once ($29.99), an "INSTALL" button will appear in its place on the 2nd computer.

OXS Lion wifi not working?

Ever since upgrading to OSX Lion, my macbook pro late 2010 model has been having a hard time connecting to my router. It would detect the router and when I try to join it, it says "Cannot connect to NETGEAR". All the other computers in my house connect just fine but they dont have Lion installed on them. And when I did connect to the router it would have a little exclamation point on the Wifi icon at the top of the screen. I would then have to wait for about a minute or two then it would connect. Someone please help.

Since I installed Lion on my iMac i5, i've had issue with Airport constantly dropping my connection to my DSL moden. It's not the modem since I have two iPads, another iMac and two iPhones that share the DSL. I've reinstalled Lion once with the assistance of Apple Support and tried everything else they asked me to do. At last report, the engineers are still working on the issue.
