Instable WIFI connection since Lion upgrade

Hi all,
Since end of June I became a convinced Apple-user when I bought my first Mac. After my recent Lion-upgrade I'm seriously considering to switch back to the Windows-platform...
Since I upgraded to Lion, I experience serious instabilities in connecting to my WIFI: at random it seems that Safari is blocking my ADSL connection; this seems to be a known phenomenon, as hundreds of users have the same problem (found this on all kind of forums).
Unfortunately, I didn't found a root-cause solution:
      -The install of the latest Lion-patch didn't brought relief;
      - also multiple forums suggested to do a harddisk- & authorisation check; also without result.
     - Switching to a fixed IP-adress is also not solving the problem.
The full reset of the iMac seems to be the only way to resolve, but this is ofcourse not a workable solution.
Any other suggestion ?
Many thanks of a very disapointed Apple-user,
Peter

update your lion to 10.7.1 and do these:
1)reset smc
2)reset pram
it works well for me.i've never suffer from the wifi problem since then!

TS1398 Still having problems with my ipad wifi connection since upgrading to IOS 6. Can Apple do something about it the soonest possible time. I don't have this kind of problem using IOS 5.1.1 Can you at least put back the 5.1.1 if you cant find a solut

So disappointed with IOS 6. I'm having weak wifi connection since upgrading to it. Can Apple do something about it? Can you at least reset it to IOS 5.1.1?

Sorry Jim for the wrong question because I'm getting frustated with my IPAD since I can't use it for surfing internet with a faster speed. Ipad was very convenient to use until this IOS 6 upgrade. Tried all the suggestions in the forums but still gets back to weak wifi connection.

Has anyone else had issues with dropping the wifi connections since upgrading to Yosemite

Looking at the Yosemite forum, it is obvious that this is a very common issue. You might want to post in that forum for help and advice.

Screen saver won't start since Lion upgrade. Two different machines, same issue.

Screen saver won't start since Lion upgrade. Two different machines, same issue. Help

For anyone following this thread, I've found a solution to my problem. Turns out that a cute widget called FishTank appears to be the culprit. With it running in Dashboard (even when I don't see Dashboard) the Screensaver and Sleep functions don't work. I turned it off, not because I'm clever, just because I tired of it, and voilà, Screensaver and Sleep are now working. It can stay in my widgets list without any problem, it just can't be turned on. I'm going to delete it anyway, however.
Hope this points the way to solutions for some of the rest of you!
Cheers!

Why does my iphone 4 keep dropping wifi connection since ios5.0.1update

Why does my iphone 4 keep dropping wifi connection since ios5.0.1 update, it worked perfectly before, my wifes 3gs connects fine and stays connected while my £400 paperweight losses connection, thinking of going back to nokia! Sort it out apple!

If the "oh so Great Apple" were to monitor these forums then they might see all the problems
that the people who have paid good money for their devices are having, i suppose they can do no wrong
In your eyes, i just thought that if you pay a lot of money for a product that works fine, and you update
It with a firmware update that they kept going on about how good it was and it can do this and it can
Do that, then i think they should sort it out. I don't care if i "don't deserve to be an apple owner" or not,
The fact is i paid my money and it should do what its suppose to do, i moved from Nokia to Apple because
The N97 was crap and i put up with it for too long, and they didn't do anything to fix the bugs they just stopped
Selling it and basically said tough s**t, so now this is happened i hoped Apple whould be better but they seem
To be just like the rest.

Wifi goes on and off, backlit keyboard doesn't work and no sound since Lion upgrade. I can get the wifi back by going into safe mode and re booting(someone suggested on here), but can't let computer die or turn off or have to do it again.

My Wifi connection goes off if computer dies or shuts off, I can only make it work if I go into safe mode and reboot, it was just that, but now my keyboard doesn't light up like it's supposed to in low or no light and in system preferences it's like it doesn't exist. Also, the sound doesn't work, I can't turn it up or down, it shows the sound icon grayed out and the anti symbol when I push F11 and F12, also it's like it doesn't exist in system preferences either. I have never had any problems with my MB Pro, I purchased in Feb. 2010. , but I upgraded to Lion last month, I haven't been using my laptop as much since I had an Ipad I given to me, so I think that's why I didn't notice these issues right away. What do I do? HELP!! Do I take it to Apple? I don't have the Apple care warranty, so will it be expensive for them to fix? Can I get my money back for Lion if I restore to Snow Leopard?

Take it to an Apple store or AASP. How much it will cost will depend on their determination of the problems. To bad you didn't purchase extended AppleCare. No you don't get your money back for purchasing Lion.

Problem with wifi connection since installing Lion OS X

Has anyone had problems since installing Lion OS X with there wifi connection? I keep getting bumped off my connection in multiple different locations ....that i never had a problem before. I installed Lion on my laptop and my Mac and I am having the same problem with both. Is there something i need to change on my settings?

One way to look at this problem is to install a Stumbler program and look at what channels are being used in your immediate area. You may find the channel you are using is very busy, and switching your Router to a channel with less competition, or setting your Router to automatic channel selection, improves the situation.
Another way to address this problem, especially since it seems to correlate with software Upgrade, is to set it up from scratch again:
System Preferences > Network > WiFI/Airport > ( Assist me ) > ( Set Up ) ...
... and re-specify from scratch, especially using a New Location.

Midi / USB drop out since Lion upgrade!

Hi all, i have had great responses and success in the past with this forum, i really really hope this will continue.
I have been gigging using mainstage 2 and a M-Audio Oxygen midi keyboard controller for a few years now and until lately it's been fantastic. I will never go back to a stand alone manufactured synth. I am using a macbook pro, 2.93ghz with 8 gb ram. I initially upgraded from snow leopard to lion when it was launched but had to go back as Creative hadn't any lion drivers for use with my emu 0202 audio interface. Last month i found that they had done them and i re-upgraded to Lion. Since the upgrade i am experiencing Midi drop outs. This is to say that whilst performing i get an error message saying something like midi input device no longer available. This has happened a few times now but last night (new years eve!!), not only did i get this message which i sorted with a reboot but a few minutes later i had a midi note hang and i noticed that there was no longer any usb supplied power to my keyboard. The answer again at this stage was a reboot.
I would ideally not like to reinstall snow leopard as there are quite a few great things in lion which i would miss, but obviously if i can't resolve these issues i don't see that i have any other choice.
Any possible suggestions as to what may be causing these problems will be very much appreciated.
Thanking you in advance
Mark
PS Happy New Year

My experience with Lion was great for a while, it was effortless, everything I had attached still worked with no problems aside from needing occasional drivers. Once Lion 10.7.2 was released, I updated my system and again, no problems. If I recall correctly, 10.7.2 was released in October. Suddenly in December, I began having random software and midi issues all around my system. I do not use Mainstage but I have noticed others have had similar problems with various software and USB midi controllers, and have not seen a fix.
I regularly use Pro Tools 8, Ableton Live 8 and occasionally Reason 5. I also have an M-Audio Axiom 61 and Korg padKontrol attached via USB. After about 2 months of trouble-free operation, Live and Reason would not open and the accompanying software for my padKontrol no longer would either. These apps would just "hang" and I would eventually have to force quit them. In addition, Audio Midi Setup would also hang when attempting to switch to the midi preferences page. Pro Tools still worked, but I could no longer receive midi signals. I also use a wireless USB stick to connect to my home wifi signal and that no longer worked and neither did the accompanying software.
It's possible that there are deeper issues in your system as well as mine and the others having similar problems.
At times, I wonder if there is some kernel errors embedded in my computer. I got my MacPro when Snow Leopard was fairly new and had numerous kernel errors resulting in many applications not functioning. I eventually sorted them out but ran into similar USB related issues with the Snow Leopard 10.6.8 update, so I remained on 10.6.7 until Lion was released.
The only successful fix I've had is switching from Lion back to Snow Leopard 10.6.7 after erasing my entire hard drive. I've tried reinstalling Lion through both upgrading from Snow Leopard and a clean install of 10.7.2 after erasing my hard drive again.
I believe my USB and midi problems stem from kernel errors somewhere but cannot find them (I have used Disk Utility many times). I really liked using Lion but I lose so much functionality and my internet connection so I have determined that I will not be using it. I may try Lion again when 10.7.3 is released but am wary. If anyone has ideas on how to fix these issues, I would love to hear them.

Since lion upgrade iMac keeps looking for old server

Hi,
I have a NAS prior to Lion upgrade which was working perfectly. Now with the Lion upgrade the NAS (Sitecom) ther were some issues. I have reinstalled the NAs and had given it a new name. I can find the NAs now so thats not a problem.
But almost every hour I get 2 warning that he can not find the "old NAS", it really start annoying me and I've looked everywhere and I don't even find any link (Finder) towards it so I don't know what to do to get rid of this message, receiving it every hour twice really start getting on my nerves.
Sorry for th Dutch, but the message translates;
A problem has occured with connecting to the server 'VanBeeckNAS'
The server doesn't exist or is currently not available. Check the servername or the IP-address of the server, ...
Any help is highly appreciated.
Peter

Same problem since lion. Not only can I not back up to the server it keeps looking for it several times on start up. Real annoying.

IPhoto library not loading since lion upgrade

Hi,
Since upgrading to lion, iphoto will not load the iphoto library anymore. iPhoto starts with the error message "your iphoto library is either in use by another application or you don't have permissions...". iPhoto was perfectly running on 10.6 (a few days ago) and luckily i have some time machine backups from before the lion upgrade.
So i tried
-to start iphoto with option+control and rebuilt the library. Unfortunately it stops with item 9000 or something.
-tried to rebuild the library with iphoto library manager, but it causes so many problems with duplicates that i stoped the process. I guess it would probably fix the library but too much hassle.
-tried to restore the library from time machine -> same error message
Has anyone experienced same behaviour after upgrading to lion? It's too bad i can't just restore from the backup (i thought that's the point of having it) but may lead to the idea, that the iphoto application might be corrupted. I tried to download the ilife image from my university's software distribution server again, but last but not least, lion does not support the server version anymore "the version of server you are trying to connect is not supported...." So no download right now...
Thx for any help and hints
regards, dorian

Hello,
I am having this extremely frustrating problem as well. My iPhoto was working perfect two days ago and today after installing an upgrade (i always keep up with them) it refuses to load and all i get is a white gear looking shaped loading symbol.
Help anyone....??
Thanks!

Try this first. 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.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.

I have WiFi problems since the upgrade to 10.10.2

Ever since the upgrade from 10.10.1 to 10.10.2 I find the system keeps dropping its WiFi connection and only rebooting both the computer and the modem fixes it although sometimes only after several attempts.

Try installing the 10.10.2 combo update

There is a huge discussion of this issue:
Frequent Panic NVRM[0/1:0:0]: Read...: Apple Support Communities
It is not caused by third-party software. The true cause is unknown, or at least unknown to me. It's either a hardware fault or a bug in Lion that only affects certain Mac models. Take the machine to an Apple Store for testing.

Cannot import Canon DSLR video since Lion upgrade

I use Aperture to import video from my Canon 60d DSLR.
Since upgrading to Lion, Aperture has designated all of my Canon h.264 clips as "unsupported video format." They will play in the QuickTime X Player, but nowhere else.
iMovie used to recognize video clips imported into Aperture and add them to the events list. Any videos added since my Lion upgrade remain unrecognized.
Has anyone else encountered this? Is this something either Apple or Canon have noted publicly? It's a total pain and it's verging on being a Lion deal breaker for me. I really want to be able to import my Canon clips into iMovie without jumping through hoops.

SdeS,
Good idea to wait. I tend to be an early adopter on my MacBook Pro, but the other machines I use will stay on Snow Leopard for now.
It doesn't seem like a Lion/Canon incompatibility. Rather it is a more generalized issue with applications being able to handle video types. I've read reports of problems with Nikon DSLRs and Flip cameras too. There are multiple reports in these forums of the problem, but not too many, which leads me to wonder if:
People haven't experienced the problem yet; or
The issue is related to legacy code or codec components on the affected users machines, but which doesn't impact the vast majority of Lion users.
Still, it is huge problem as I would like to use my Mac to edit HD footage shot with my DSLR (or Flip camera for that matter).
You're right, Apple obviously missed something in their beta testing, because with respect to video, Lion doesn't appear ready for prime time.

Instable WIFI connection since Lion upgrade
