Wifi Network Problems CoreDuo iMac 20"

Just upgraded to 10.5 and now my iMac will not recognize my wireless network. In fact during a clean install it didn't find my router or access-point. I never had this problem before I upgraded.
The only way I can get it to work is going into the "assist me" option in the network settings and it then works. But after a reboot I loose the connection again. I don't mind the work around at the moment, but it now means that my dad cant use the computer unless I sort the connection out each time. Very disappointed with 10.5 at the moment....
Does anyone know if this is a bug??

Howard,
What was the solution to your problem?
Thanks,
Paul

I'm in the process of creating a WiFi network from my IMac to my LG HDTV. I am incorporating a LG WiFi capable Blu-ray player and will purchase an Apple Express or Apple Extreme router. I need some advise on using this aquipment.

I need help in determining the best way to create a WiFi network from my IMAC to a WiFi capable LG Blu-Ray player that will connect to my LG HDTV. Since I will only need one network I need to know which is the best Apple Airport router to use (Express or Extreme). What is the correct way to connect these units? It seem self explanitory,but I'm checking my thinking. My HDTV is about 20' from where the airport router will be installed with a wall between them. Has anyone created this network? Is this the best way to create a WiFi network?

How do I add an Airport Express to extend the range of my WIFI network with my iMac as a base station?

Hi people
I need help to configure a new Airport Express only to extend the range of my WIFI network.
My ethernet cable from modem is connected directly in my iMac and I am sharing the internet by WIFI inside home very fine.
Now, I would like connect my devices on my garden on backyard.
I can't move my iMac from their place and i just want add a Airport Express between the iMac and backyard to extend the range of WIFI.
But I can't to configure to that. On Airport Utility appear the Airport Express connected directly to internet globe, but don't work.
So, what can I do? What is wrong?
Thanks all and best regards.
Carlos Sgrillo, from Brazil.

The AirPort cannot do what you ask.
The Airport needs to connect to a modem, or another router......not to a computer.
The Express can only extend a wireless signal that has been provided by another Apple router.

How do I remove a wifi network account from iMac? Or how do I encrpyt an open wifi network account to make it secure?

Somehow a wifi network connection has been created either on my airport router or iMac or iPad which is non secured, I.e. Open. I cannot workout how to delete it or make it a secure connection. My concern is that other users may able to access my computers via this open wifi connection.
What can I do to correct this?

click on the wifi icon and go all the way down to network preference click and open it once you on network window on the bottom right there is a advance icon click that then you should be able to delete all the network that your mac is remember.
hope this is help.

Windows Vista and WiFi networking problem with MackBook Air

Hi, everyone!
Thanks in advance for the following help.
For some specific programms I need Windows Vista to be set up on my MacBook Air.
The problem with Broadcom WiFi adapter.
While moving large files over home network it hangs and looses the wifi network. It works OK while surfing the internet or doing other low traffic job. But when it comes to 2 MB/sec transfer it doesn't work. I tried two different routers, no positive result. PC works propely on any file sizes. After booting the Leopard the problem goes away. So it is onle Windows Vista problem.
May be drivers? I tried 4.170.25.19 Windows Vista drivers from Broadcom - it didn't help. But I am not goog in driver settings in Control Panel, so may be the solution is there.
Any ideas how to solve it?
Thanks for help in advance.
Andrey.

Hello Nescom. Welcome to the Apple Discussions!
I'm afraid I really don't have an answer for you but I can offer my experiences with large files transfer with Vista. My current home network is a combination of Windows PC, Windows Servers, and Macs. Large file transfers between most of them have relatively the same performance, except when transferring large files from the Vista PC to any other OS. It is demonstrably slower. Interestingly, transfers between Vista machines does not appear to be a problem. I understand that this is a known problem by Microsoft and was supposed to be fixed with Vista SP1.
So the problem might not be your network, but Vista itself. I'm curious if you have this problem when transferring large files to another Vista device?

G585 wired and wifi networking problems - please help!!

Just purchased a new G585 a couple weeks ago. After trying Win 8, I realized what a complete POS of an OS it is and installed Win 7.
2 Major problems:
1. Ethernet connection erratically disconnects - no rhyme or reason - sometimes works other times doesn't. I've tested on two diff networks - the same behavior.
2. Cannot install wifi - tried the drivers from Lenovo site - no go - tried drivers someone had recommended (broadcom wifi5.100.196.18) these did not work either - device still unrecognized in device manager
This is my 9th Lenovo laptop over the years. The others were great. This one seems to have serious issues.
Can anyone assist please???

I have had these same connectivity issue since I bought the laptop in March of 2013. It is January 2014, and is will still drop connectivity for no apparent reason, be incredibly slow when it IS connected, and sometimes just sop seeing the network altogether (and this happens on every netwrok I have attempted to connect to).
The most obnoxious thing is that after spending several hours over multiple days on the phone with tech supprt, they said I needed to send it in for repair. So I did. It was gone two weeks and when I got ti back, they claimed that had repaired it, but everything was exactly the same.
Combine that with the lack of help for the company and the fact that this seems to be the only laptop where edge swipes on the touchpad cannot be disabled, this Lenovo laptop is the worst computer I have ever owned, period. And I mean ever.
If there ACTUALLY IS a way to fix this issue, I would love to hear it, bit nothing that anywone ever suggest actually works. I thought maybe if I upgraded to Windows 8.1 it would help, but the Lenovo site lists the G585 as a model you shouldn't update because of monitor driver issues witht he upgrade. It really looks to me like Lenovo has written this model off completely.
I will never buy another Lenovo product and I will direct other people to other brands. Words cannot describe my frustration and disappointment.

Two WiFi/Networking problems with a T43

Hi. I had a T43 for a few years and loved it but in Sept, it just died. wouldnt turn on. Took out the hard drive.
Just got another T43 (actually 2) and swapped in my HDD. both had the same problem and I cannot find a fix on the website...
Everything works well on them with my HDD. I have been running programs, etc. and also am on Internet thru a wire, but it has 2 problems..
1. It doesnt show that there is a wifi card (same with the other 'new' one that someone else took and installed their OS on the HDD (XP Pro) and found the wifi card. Nothing shows up in device manager under network cards except the gigabit card and the bluetooth (both work) but NO Wifi. Belarc Advisor doesnt show a WIFI card, My guess is that there is one there but something isnt allowing me to see it.
2. In Device Manager, there is one item that has the yellow question mark, it is the "Network Controller" I went to the Lenovo website and also googled it, and cant find a driver for any such device. I am wondering if it has to do with why the WiFi doesnt show up. where can i find the driver and what IS the 'network controller' anyway??
any help would be appreciated. I love the T43 and need it to get working fully asap.
THANKS
Solved!

Wireless networking problems using iMac, Macbook, airport extreme & express

Here's my setup:
iMac in study has 100+ gigs of music on an attached hard drive
iMac running 10.5.8
Airport extreme in study
Macbook in living room that I use Itunes to connect to hard drive in study
Macbook running
iTunes on Macbook has it's Media Folder as the one that's on the hard drive in the study.
Airport express in living room, with direct connection to stereo
To play music on the stereo, I prefer to use the Macbook to connect to the iMac/hard drive in the study, as I don't want to keep walking into the study to change music.
Once I get a connection it's usually ok, but the problem is in getting a stable connection in the first place. Sometimes I have to go through a rigmarole where I turn off all the computers and then turn on iMac, hard drive, Macbook, before connecting to the iMac wirelessly before playing music. Sometimes I might need to do that twice before it works.
If I don't, I get the message in iTunes on the Macbook: Connection failed - The server "macintosh-2" may not esist or is unavailable at this time. Check the server name or IP address, check your network connection and try again.
Sometimes I'll have access to most songs, but a certain few will get the message above.
Is my setup the thing that's causing this 'slippery' network connection?
I'm wondering whether my hard drive isn't fast enough - it's a no-name brand which I got cheaply about 5 years ago. Maybe it's just not up to it? Or is it the fact one puter's on Tiger, one's on Leopard?
Any advice would be greatly appreciated.

have you checked for _*wireless interference*_ ?
download iStumbler (may not work on 10.6) or AirRadar (it has a trial period) and note the channels other networks in your vicinity are broadcasting on. change the channel(s) of your network as far away as possible from those.
any improvement ?

possible but i doubt it. in my iTunes test environment, i have a cheap USB drive connected to my TC. iTunes fetches tunes from it via the network, then streams the music back via the network. i have no issues streaming even HD movies in the 10 gig range.
i assume the extreme is your main router ? what you can try is hardwire as much as possible, i.e. run ethernet cables from the extreme to all Macs. if physical cables is no option (due to location), you might consider *powerline adapters* _*such as these*_.
here's an interesting read on the subject.
Or is it the fact one puter's on Tiger, one's on Leopard?
as long as all Macs are current on the software side, it shouldn't matter.

IPhone wifi-network problem- Please Help!

I have a problem with my iPhone4. It could only connect to the internet for a couple of minute then it dropped off. But it is still connect to the wifi though and in my Mac the wifi seem to be working fine. Any ideas?

first start here
http://www.apple.com/support/iphone/wifi/
If that doesn't help then
Restore as new, if wifi works add your backup and proceed .If after backup issue returns
Then you have a corrupt backup
If when restored as new no wifi then you probably have hardware issue and should take it to an Apple Store genius bar

Try restarting your router by removing power for 30 seconds. Next, reset network settings on your iPad (Settings > General > Reset > Reset network settings) and then attempt to connect.
Do you have any other devices working on your network?
Do you have a backup from previously synching with iTunes? If so you can restore you music and Apps from it.
Apps can also be loaded into iTunes on your PC and synched to your iPod.

Ethernet wifi network Problems

Hi,
I'm not really sure where to post this, but a Mac Mini is in the middle of it, so here goes.....
My setup Wireless:
MacBook Air 2012 running 10.8.4, MacBook Pro 2010 running 10.6.8
Upstairs room for phone socket
had a TP Link Router supposedly 300MB/s model Router On the MBA it only showed as 150MB/s link.
Have now changed to Sky router, disabled WiFi on the Sky router, and have an Airport Express running from it, via a Devolo 85Mbps Powerline.
My office
Mac Mini 2.3GHz i5 8GB Ram as main work machine running 10.7.5 wired into the switch below:
I have a Synology DS212J wired into an unmanaged Gigabit switch Switch, as well as
LG NAS also plugged into the switch
IP camera also plugged in.
one of the Powerlines via the
I know very little about networks, its a bit of a mystery.
Copying from MBA to Mac Mini is unbelievably bad it shows 3 hours for a 1GB file. Mini to MBA is better, but not much, maybe an hour for the same file. Copying to or from the DS212J can be slow as well.
If I'm copying a file to or from the DS212J and playing a video from it at the same time, the Video will stop. Thats playing the file directly using VLC, not streaming using Plex or anything else.
I've tried using Wireshark, but I might as well be looking up a cow's ***.....
MBA to Mini plugged into office switch 500Mb file 45 seconds latency .40ms Network speed 92.67Mbps
Mini to MBA plugged into office switch 500Mb file 46 seconds latency .87ms Network speed 89.31Mbps
MBA (Wifi) to Mini plugged into office switch 500Mb file takes forever latency 14.07ms Network speed 4.21Mbps
Mini to MBA (Wifi) Mini plugged into office switch 500Mb file takes forever latency 129ms Network speed 3,5 Mbps
Having jigged around the ethernet cables different combinations, there were speeds of 500/600/700mbps between machines wired via the switch.
2.16GB file Mini to DS212J NAS both wired 4min 4sec. Wireless - over an hour......
2.16GB file Mini to LG NAS both wired 2min 10sec.
Running Speedy net at the moment, I put the two MacBooks, Pro and Air running Speedy Net sending files to each other and they were tranferring on WiFi on 40ishMbps, which seems reasonable. They transfer files at this speed, but once I try to send to the mac Mini on the wired network its down to 2mbps.
I tried to send the same 1.6Gb file from Air to Pro and vice-versa and it takes 3/4 minutes.
I try to send the same file to the Mac Mini or the NAS and it is showing over an hour.......
Both switches show green lights on all connections, so no 10/100MBs devices.
I have turned everything to IPv6 to off or local link and that seems to have improved the wifi copying, but there is a serious block when trying to send anything from the Macbooks into the wired network.
What am I missing?

MBA (Wifi) to Mini plugged into office switch 500Mb file takes forever latency 14.07ms Network speed 4.21Mbps
Mini to MBA (Wifi) Mini plugged into office switch 500Mb file takes forever latency 129ms Network speed 3,5 Mbps
Hi Wayne, from the above it almost seems like it's copying through the Internet instead of locally, what are the invilved IPs?

Setting up a WiFi network from iMac... works on "old" iMac, not "new"

Hello,
I hope I'm not crazy, or even worse, stupid.
I an running two iMacs in my home office. Old one= 21" 2 Ghz PowerPC G5, purchased summer 2005 and still running like a champ. New one=27" 2.7 Ghz Intel i5. Purchased the new one July 2011. I have a cable modem plugged into the ethernet port on the old iMac. I've been accessing internet on new iMac with wifi and the internet sharing network I set up on old one. I also use wifi on my ipad and laptop. I have never had even a single dropped wifi connection on any of these devices.
I pretty much expected the same kind of result and performance when I reset the cable modem and plugged it into the new imac and took similiar steps to set up internet sharing/wifi network on new iMac. This has not been the case.
What's happening is:
The cable modem plugged to new iMac is working fine; verified with ISP. I set up wifi network on new iMac and turn on internet sharing. I locate my network name on ipad, laptop, even the old iMac, and I see the name in the list, so I figure so far so good. The signal icon appears in menu bar as usual. I open a web site to verify it's working. And it's working...for about 20 seconds. Then I get alert messages that there is no internet connection.
After creating a bunch of new networks and changing channels, changing type of security, even passwords, I realized I wasn't going to figure this out by myself. I'm not a technical person; Apple spoiled me and I stopped learning how to do anything except plug stuff in 20 years ago.
I started researching online including these discussion boards and answers have ranged from "It's the iMac! It's a hardware problem they never fixed! The aluminum case gets too hot!" to, "there's no airport card and you have to buy an external router." I gave up and called Apple, thinking surely they'd be able to give me a straight answer. Ha ha. Nope.
Of course the bottom line is I could buy applecare (haven't yet...haven't used the computer hardly and I'm still under warranty), I could buy telephone tech support, or I can take the machine to the geniuses.
I keep thinking this can't be that complicated. When I buy a new iMac--this is my 4th one--I expect things will get easier, not this complicated mess.
Oh, last I want to include I just reversed everything back to the way it was. My old iMac is connected to the cable modem and the old iMac is back to being my wifi network, sharing internet with the new imac, my ipad and laptop. Easy as pie.
I'm making an appointment with the geniuseses but hoping it's just something I'm too dumb to realize I'm doing wrong.
Thank you in advance for your patience; any help is much appreciated!

It never occurred to me that the wireless network/internet sharing thing wouldn't work just as well if not better on a brand new machine with the improved technologies I pretty much expect. Metal could be interfering with the signal? The machine is aluminum!! I'm no engineer but that seems kind of...flawed. I just don't understand.
I think the WiFi antenna is near an edge of the computer to avoid being encased in metal. It should work like t did in your old computer, but as I said, the use of a Mac to share an internet signal is much less common than use of a router so even if the newer computers have a non-optimal design, it might not get widely noticed in forums like these.
Sounds like AppleCare is what you want, so I'd get it and then have them check that your Mac is transmitting thru the wireless card/antenna as strongly as it should be. The antenna clearly works as you can RECEIVE a signal, but the transmitter uses different circuitry than the receiver. By the way, I think AppleCare is a good thing to get for iMacs and for laptops as they are very compact and tend to be more prone to thermal problems than other desktop computers.
I have no idea about routers aside from, of course, the apple air port one that the phone tech support guy mentioned. Are there others that are less money and just as good? I don't feel like rewarding apple for selling me a product that doesn't do what the earlier geration machines did without a problem. Seems like they shouldn't make another $200 because of their flaw. My old iMac's wifi signal was strong enough for a 3500 square foot house, 2 laptops and an iphone.
Would getting an external router definitely solve my problem? Which one would you recommend if I go that route?
I also did not understand why the Apple routers (Airport) were so much more expensive than other brands. So I purchased a linksys n router some years ago and it has worked quite well. They are very easy to configure through an ordinary web browser (some Mac folks prefer the Airport utilities that are used to configure the Airport routers, but I find the web browser interface very easy to use for the non-Apple routers), and they are in very widespread use (linksys isn't the only brand that is good for this, there are others, but I've had good experience with both Belkin and Linksys). You can get very high performing n routers from Belkin and Linksys for under $100. I'd get a router that has dual band (2.4 GHz and 5 GHz), and I think most include standard features like MAC filtering (a security measure), WPA2 security, and I thiink offering Gigabit ethernet ports would be good also in case you connect something to it like a hard drive server or a printer or want a fast local network sometime in the future.
I think the router will solve your problem and do a better job of wirelessly distributing your internet signal, but if the problem is due to a faulty wireless card (that receives fine but doesn't transmit properly) in the new iMac, I'd want to get that fixed under warranty (or AppleCare) now rather than later.
One more thing: if your wireless card in the new iMac is working properly but the physical layout is such that the internet sharing isn't working well, you OUGHT to be able to eventually get it to work by moving the other devices you are sharing with around to different locations, as eventually one should end up in a spot that works. If nothing can receive the shared internet from the new iMac, even when 3 feet away, then something might well be wrong with the new iMac's transmitter.

IPhone 4 does not see my home WiFi network anymore.

All of a sudden, a few days ago, my wife's iPhone 4 (initially with iOS 6.0.1, now with iOS 6.1) does not see anymore my home WiFi network (created by a Time Capsule), to which it connected automatically.
This has worked flawlessly for years but now the home network (nothing has been changed to its configuration) does not appear in the list of networks seen by the iPhone 4 (mine, iPhone 5 - iOS 6.1 - has no problem at all) and when trying a manual connection I get an error message saying that the network was not found. When I tested, I was a feet away from the Time Capsule.
I have turned the iPhone off and on again twice, to no avail. Just to try something, I created a new WiFi network from my iMac and it was immediately seen by the iPhone 4.
I don't see what could explain these symptoms and what would be the cure.
Help welcome
Thanks
Jacky

No luck. It changed nothing to iPhone behaviour.
Thanks anyway.
