Also try this - Turn Off your iPad. Then turn Off the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.

Trouble with internet connection after update to Snow Leopard

Happily surfing the internet with the most recent update of Tiger until deciding to upgrade to Snow Leopard so that I could connect to a wireless printer. Noticed almost immediately that Safari was spotty, sometime normal, but often painfully slow. Have checked forums that suggest dumping caches, reseting Safari, repairing permissions, doing fresh install of SL. Nothing has worked. Can't even get internet with Firefox. Internet connection seems to work after I start up, but then fails after 5-10 minutes. Most of the time it doesn't work at all. Doesn't seem to be a problem limited to Safari since Firefox won't work either. Phone support tried saying that SL likes a WPA router connection and not WEP, which is the current setup.
Finally, I decided to boot to my clone of Tiger. After a little bit of fussing around setting up the internet connection over Airport everything works just fine! What's wrong with SL and how can I fix it. Really like the iLife11 upgrade and being able to print wirelessly, but if I can't get internet access that makes it rather pointless. Know this is a lot and rather hastily written, but please help!

Hello
Sorry, I have no answer to your problem. I just want to share that I amexeprience similar issues with my iMac since I upgraded to Snow leopard :
The LAN connection of the iMac slows down after accessing Internet, usually less that one hour. I can measure it through an Internet throughput utility on my provider's home page.
I have two Macs connected on the same DSL box, with the same OS version, Snow leopard, and nearly the same sofwtare configuration. Thus I can compare the Internet access speed :
After starting the computers, it is above 12 Mb/s.
On the iMac that I use most for Internet, it slow down to more or less 2 Mb/s after a few minutes, whereas it stays at 12 Mb/s on the MacMini.
Because of this, I believe it is LAN problem, not an Internet/DSL problem.
The same phenomenon happens if I connect to my DSL/Router with Ethernet or with Airport. The speed drops to similar values, below 3 Mb/s. Thus, the problem dose not seem to be related to LAN connection hardware.
Curiously, the speed is high again after shutting down and restaring the iMac. But it slows down again after a few minutes. Putting the computer to sleep does not help to restore maximal speed: it has to be shut down.
From all this, I draw the conclusion that the problem lies in a LAN software layer that is common to Ethernet and Airport and that is restarted only after shutdown.
I am using the MacMini as a reference for Internet access performance, in order to have a benchmark for iMac performance. I hav enot tried yet if the LAN performance of the MacMini collapses in a similar way if I use it to surf on the net.
I hope this will be helpfull do draw some attention from experts at Apple. It looks like a bug in a Snow Leopard LAN software layer.

fair enough. No need for any unnecessary posts either. You issue had been addressed ad nauseum already in this forum had you bothered to search this forum (as forum etiquette would dictate) before posting.
In any case, I hope that your problem was solved.

Problem with Internet connection sharing between eMac and Powerbook G3

Hi,
I seem to be having a slight problem with internet connection sharing.
My eMac is the main machine with the internet connection, and its running 10.4.6, the Powerbook G3 is running 10.2.8.
I can connect them all up and get online with both, but I the problem I am having is when I turn the Firewall on on the eMac, the powerbook can't connect.
Is there anyway I can keep the Firewall enabled and still use internet connection sharing?

How do I know which ports the Powerbook is using?
Also I had web sharing enabled on the eMac and it made no difference at all.
Plus I don't know if this means anything to you, trying to decipher it myself, all I can make out myself on there is port 80.

I have been on the phone twice today with my carrier. They reset it the first time, it worked for an hour then messed up again. They reset it a SECOND time..

Problem with internet connect?

Hi,
I have installed a Netgear wireless router, which is connected to my eMac by an ethernet cable. I can access the internet through Firefox without a problem, but when I try to check software update or get to the itunes store it says it cannot connect to the internet. I think that this must be something to do with internet connect, as when I log in a error message comes up on the screen and also the only options for connection when internet connect is opened is BT Voyager 105 (the previous ADSL Modem) and Internal Modem.
If anyone can offer any advice I would be very grateful!
Thanks very much,
Claire

Hi David,
I opened up Safari, went to preferences, and then clicked the advanced tab. There should be a button saying 'Proxies: change settings', I clicked on this and it opened up the network settings (through system preferences),and found that it was trying to connect through an old proxy set up whilst it was on a university network. I simply highlighted the proxy (xxxx.ac.uk), pressed the delete key, and then clicked on the apply now button. All seemed to work then! I suspect I was just lucky that this was the only cause of the problem, as it seems that some people have not been able to resolve their problem this way.
Hope this helps in some way,
Claire

Problem with Lightning Adapter after update to IOS 8.1

Dear all,
last week I updated the Iphone 5S of my wife with IOS 8.1 since that time we can not connect the B&W Bowl via lighning adapter (Original Apple).
Before never any problem. I have the new Iphone 6 but IOS 8.02 and no any problem with same adapter to connect the B&W Bowl.
I also checked in my car same problem with IOS 8.1 we can not connect but with 8.02 no problem.
I contacted the Apple support and it looks it´s a problem with the new IOS 8.1.
Does anybody have the same problems with the connection to Docking Stations etc ?

Problems with Wireless connection AFTER 10.4.2 update

I have read several topics on wireless problems AFTER the 10.4.2 update and wondering if anyone (or Apple) has found a fix to this problem. I cant get to my network or the internet via airport. I have tried zapping the pram, resetting the permissions, rebooting, checking for more update on a wired connection, reinstalling both 10.4.2 combo and 4.2 update and still nothing. This happened RIGHT after the reboot upon completion of the update. Im stuck and wondering if anyone has a solution or has any one SUCCESSFULLY contacted Apple and have they got a solution to fix the problem??

I'm having the same problems with accessing my airport base station (first generation snow at 4.0.9) after loading the airport admin 4.2 patch. I loaded the 4.2 patch on my g5 and G4 running 10.3.9. The response/across of the wifi connection is very poor. I can't use chicken of the VNC to manage the G4 from the G5 anymore at all due to the slow response and accessing the internet via either the G4 or the G5 is like a dial up connection. The broadband speed test results are 192mb to 274mb up and similar down.
I have a 12"powerbook (DVI 1gig version) with 10.3.9 that I have not loaded the 4.2 patch on and I am not having any issues with wifi access to the base station or the internet. broadband logs in right at 2.8mb via DSL. I also have a Dell laptop that I access the internet through the airport base station and I have no issues with speed and the same 2.8mb broadband speed test results.
Conclusion something in the airport 4.2 patch has changed the airport cards ability to see the base station.
With all that said, my question is - How do I back out of the 4.2 airport admin patch provided by apple or how do I resolve the slow response times between the airport cards in the G4 and G5 and the base station?
Any help?

Anyone having trouble with internet connection after downloading mountain lion

After installing Mountain lion to my mid 2011 imac 21" I am having trouble with my internet connection. Anyone else have to deal with this?

Are you on 10.8.2 as ypur profile says? If so, it's worth updating to 10.8.3 which was released last week.

Here's a link to some suggestions that helped some users with similar problems in Lion. May still be relevant to MLion. Also check the links within the article:

Also when I had wifi problems in the past, creating a new network location resolved it:

I've also seen threads where users with wifi problems have successfully solved them by changing the channel in the router's wifi settings.

Update OS 10.5.5: no more internet connection after update to 10.5.5

Since updating to 10.5.5 yesterday, I can not connect to the internet nor email anymore.
My Time Capsule (Airport) is working fine because I can connect using my iPod Touch that is also using it.
By the way, I've sent this message using the Explorer browser in Windows XP, running on the SAME Mac with Parallels emulation, which is working fine. Strange, hm?
I suspect the bug is in the update. Now I wonder how we are going to do Software Update without internet connection.
Anybody have the same experience?

This thread caught my eye, because I have spent a lot of time trying to help people with internet problems... and the solved status made me curious! There seems to be a few people with the DNS changer trojan horse at the moment..
I wonder how it got there.
Trojan Horses are usually installed when you agree to provide your admin credentials to install some software (whilst visiting a website).
Installing software from the net that you have not explicitly verified first (through mac forums) is generally a bad idea. Once you have given a process your admin credentials, it can do whatever it wants to your system.
This is also a reason why it is a bad idea to run your regular usage as an Admin user. It is possible to install software as an Admin user without entering any username/password - and it can easily give itself root access to your computer.

Skype problems with Airport Extreme after update

I use Skype to call regular phones and landlines. For over a year now it has worked well with my Airport Extreme, however, I noticed that around the same time I updated my Airport utility to 5.5.2 and Mac OS X update on 1/7/11 I am having problems with audio getting scrambled, the person on the other end dropping out, and my voice dropping out of their calls and the sound of me "being in a long tunnel," as they describe it. If I plug the ethernet directly into my computer there is no problem so I know it is the Airport base station.
I have tried plugging and unplugging the base station and I had comcast reset my cable modem but nothing seems to be working. I have 12 mbps internet so I know it is not a bandwidth problem.
Please help! Thank you!

Indeed I have the same problem. I ended up buying a new router because I thought mine was malfunctioning. After buying the latest generation Airport Extreme, turns out it's having the same problem. I agree that it was not a problem until 5.5.2. Also, I use YouSendIt constantly and it also chokes the Airport Extreme. It appears to happen in scenarios of high bandwidth usage.
5.5.3 maybe coming soon?

HT4589 Problems with FX Factory after updating

I just updated to FCPX 10.0.6, but as soon as I did it I started having some problems with third party plugins, such as Luca's Visual Effects by FX Factory. This both on my MAcBook Retina 15" and my MacPro Early 2008. After rendering, strange things happen to the clips: black gaps, transitions out of sync, etc. Does the same happen to someone else?
Thank You
Filippo

Filippo,
Yes, I made several posts to another thread about seeing pink and green flashes on the screen. I too use (and love) Tonalizer and have been in touch with them. I am using Lion 10.7.5 on a mid year 2011 MacBook Pro with 256mb of video memory. The Tonalizer people said that they haven't seen this on machines with 512mb of video memory, but since it work for me and others before it should work now unless Apple has made some changes and not informed their third party vendors. I'm not working on a paying project, but I am not happy about this.
