IMac G3 internet connection?

Hi...my Imac has an internal modem that i use to connect to the internet with, still using a dial up phone line. I'd like to switch this and get a high-speed internet connection using a external cable modem..where do i hook it up to my iMac?
thank you!!!!

Certainly in the UK you will are likely to be given a free USB Broadband Modem when you subscribe and then offered the chance to buy an Ethernet Modem. Either way your iMac will be compatible. If it's USB then drivers become an issue, so you'll need to check the ths Internet Service Provider (ISP) will provide you with Mac support/drivers - some won't even though it's all simple stuff.regards

Can I share my iMac's internet connection with my Touch?

I have a DSL modem and do not have a wifi network setup. Using Lion, can I still share my iMac's internet connection with my Touch?
If so can you give me step by steps? Will this be something that I can turn off and on without interfering with my regular ethernet internet connection?
Thanks. Asking this for a friend who is scared that she will somehow mess up her existing internet connection if she tries to set this up. She
called AppleCare to get them to walk her through this and they denied any knowledge of the ability to do this. Huh?

OK. Remember this is just a form of texting, so it's not easy to discern whether a question is explicit or rhetorical. Sometimes you have to give the reader a clue.

I Fixed my iMac slow internet connection

I will share with you how I fixed my iMac slow internet connection and frequently lost connection. At first, I thought it was the Airport but then it wasn't the case. I also had a Dell laptop in the same basement and it was running as fast as I expected. Here are the steps:
1/ Open Airport link on the top right window > Open Network Preferences
2/
Click + to create new Network Name and Security, I chose WPA personal - less security than the WPA2- that is why it runs faster.
3/ Go mack to step 1 and select your new network name > Apply.
May iMac is now connecting to internet as fast as I would expected.
Good luck

My iMac internet connection is not faster but as fast as it used to be. I was using WPA2 and it was really good for a year and then I got disconnected or very slow. So I created the new network bearing the same old name but use WPA and did not delete the old one, some how everything is back to normal.

IMAC Wireless Internet Connection Problems All Of A Sudden

My Imac is well over a year and a bit old and has been able to connect to my wireless internet connection absolutely fine until the past week and a half. At first the connection wouldn't work and when I would turn my airport on and off and reset the router, it would eventually work, now that is not working at all. My airport status is either showing 'airport is turned on but is not connected to a network' or 'airport has a self-assigned ip address and may not be able to connect to the internet'
I have formatted my imac twice and still no avail and the last format I tried to join wirelessly straight from boot but it wouldn't join saying 'there is a problem with the wireless connection and you're not connected to the internet.' the annoying thing is I can see the network sitting there and can't join it, my network is also unsecure so no need to input a password. All my home PC's and my Iphone and Blackberry find the network easily enough, although recently the Iphone has began showing only 1 bar of wifi connection.
I am at my wits end as I am unable to connect at all now, I am all out of ideas and have been bashing my head off a wall for the past day without any connection at all.
My router is a buffalo AirStation wireless G high power model, my IMAC is an intel core 2 duo 20", if you need anymore information of my hardware I will gladly provide it. I'm running MAC OSX Leopard 10.5, out the box as I've been unable to run any software updates as I can't connect to the internet.
Please, if anyone can shed any light at all on this issue I would definately try anything.
Thanks in advance and regards.

Anytime you see a self-assigned IP address in your network prefs you know it surely is a problem
with your router configuration. Power down all equip ... make sure modem is off for at least 5 minutes
restart modem, restart iMac ... check your network pref on iMac and make sure it's not 169.x.x.x
If so you will need to recapture the settings from your ISP's modem to the Buffalo.
Always use a secure wireless connection (WEP, WPA, WPA2) or else the whole neighborhood will suck down your bandwidth the slow down what your paying for. I use Time Capsules or AEBS (Airport Extreme Base Stations) that allow you to stealth mode and lower signal output and make the device
as a "closed network" ... meaning no one else can see and tap into your WIFI home network!
802.11N is better than G. and especially when you can use dual bands 2.4 / 5GHz to stop various home interferences. The backup of Time Machine only makes life much easier also! Xtech

Iphone blocks imac's internet connection

My iPhone 3g, with firmware 2.2, appears to block the internet connection for an iMac (Intel 2.66 core 2 duo, 10.5.5) which is connected to the internet via a wireless connection to a router. This happens intermittently, and stops when the phone is switched off, or the wireless is turned off. The phone can access the internet through the same router even when the iMac can't.
Any ideas why this might happen?

Hello Anjan,
There are several potential causes for the symptoms you're describing.
If the wireless router is not setup to distribute IP addresses via DHCP or it is setup in bridge mode, you can have issues getting multiple clients on the network.
If the Ethernet cable from your cable or dsl modem is plugged into one of the LAN ports instead of the WAN port on the wireless router only one client at a time will be able to join the network successfully.
You didn't mention what brand or type of wireless router you are using. If it is an Apple AirPort Base Station, you can find troubleshooting info in this article:
http://support.apple.com/kb/HT1401
If you are using another brand of wireless router, you may need to refer to the owner's manual or contact their support.
Another thing to try would be to power cycle both the wireless router and modem - removing the main AC power from both for 5 minutes and then powering up the modem first, and then the wireless router after the modem's LEDs are in their normal running state. If you have a VoIP phone system with your cable provider, the modem may have a backup battery inside that will prevent the device from resetting even when disconnected from AC power - if this is the case, contact your ISP for information on power cycling the device.

Anyone having trouble with IMac dropping internet connections? inter

My IMac is dropping my internet connection?
Any ideas or suggestions on what is causing this?
george

I too have this problem but I've had it for about 2 years. We used to think it was because I was on wi-fi and I was getting interference. I moved the modem closer and that didn't help. Then my ISP kept telling me it was my Dlink modem so I chucked that modem out and went with my ISP's modem. That didn't solve the problem but at least my ISP couldn't blame it on other equipment. I then moved the modem right beside my iMac and I was still loosing the connection while on wi-fi. I got so fed up that I have hard wired my iMac right into the modem and it's still happening. Ive had my cable company out here a zillion times trying to trouble shoot this. They changed all of my cabling from the road to my house and from my house to the computer. They gave me a new modem and then they gave me another new modem but a different brand. I'm still dropping my internet connection every few minutes.
The one thing that I discovered with my provider is that I'm not actually loosing connection to the internet as they don't see my internet dropping at all. It's as if the signal comes and goes on this iMac and when it goes, I'm left with my curser doing the whirley-bird until it reconnects to the net. Usually takes 5 minutes or so but it eventually comes back. My wi-fi is fine with my iPad and my iPhone but it wasn't with this iMac. I've been on Leopard, Snow Leopard and Lion and I've had the same problem with all three OS's on this iMac.
I'm totally at a loss as to why this is happening. It's very frustraging and makes it near impossible to use online banking or booking flights etc because I can't keep a connection long enough.
Anybody have any brilliant suggestions to try?

How to share iMac WiFi Internet connection without a router

I would like to know if I can link my iPod Touch (new one) to my iMac so that share my internet connection via wi-fi via Airport at home without a router.
I have tried to like my ipod touch to iMac by turning airport and setting up a new network, the ipod touch is able to pick up the wireless signal of my iMac ant the Airport status bar shows an arrow out which mean that airport is sending signal out but for some reason when I try to use Safari or Mail in get the following error message "cannot Open Page Page, Safari cannot open the page because it is not connected to the internet"
Also when when scanning for wireless signal with my iMac I am able to pickup my neighbours wireless signal while my iPod Touch is only able to pickup my iMac airport wireless signal.
What I am missing ?

1. Open System Preferences
2. Go to 'Sharing'
3. Click on 'Internet Sharing' (leave the box unchecked for now).
4. From 'Share your connection from' choose 'Built-in Ethernet'
5. From 'To computers using' check the 'Airport' box
6. Open 'AirPort Options' (bottom right), name the network. (Once it all works, go back and assign a password).
7. Now, check 'Internet Sharing' box and turn on AirPort. The AirPort sign on the iMac menu should turn into an arrow.

Imac losing internet connection

Hi my imac keep losing its internet connection, it does this twice in a couple of hours and everytime I put the mac to sleep, I have been into the network settings and put my wifi to the top of the list, but this has not helped. I have Mac OS X version 10.7.5 2.8 GHz intel core i5 and 4GB if that helps. Thank you

I have been having having a similar problem for the last several months. When I turn on my Imac about 70% of the time it does not connect to the network. I have to click on the Airport icon on the menu bar and wait about 5 seconds before my network shows up. Then I can manually connect to the network. Very frustrating.
One thing that has helped others but not myself is changing the multicast rate to the lowest possible setting. (Utilities, Airport Utility, manual, wireless, wireless options).

Why does my iMac lose internet connection when importing music via iTunes Home sharing?

Hi, I tried searching for a solution but could not find anything to solve my problem.
I recently purchased an iMac and am attempting to import my iTunes library from my old Windows 7 laptop using the Home sharing function. As far as I can tell, everything works fine - both computers are connected to my wireless network, I can see and connect to the library, I can begin importing my music but after 5 or so minutes my iMac will stop transferring music and I can no longer access any internet sites, even though i seem to be connected to the internet. Turning wifi on and off allows me to access the internet again. I have tried many solutions, but nope seem to have helped. Both computers have the latest version of iTunes. I have tried disabling the firewall on my router, resetting the router, resetting both computers, reopening iTunes.
Does anybody have any ideas as to what could solve the problem? Thank you

I've noticed that Lion automatically reconnects in about 5-10 seconds after being waken from sleep mode.
Make sure that you've set you Network connections up properly in System Preferences and then, after waking from sleep mode, wait to see if it automatically reconnects.
In System Preferences:
Network / Wi-Fi:
Make sure "Network Name" is specified.
Advanced:
Make sure your "Preferred Networks" are specified. (The order is significant).
Also make sure that the "Remember networks this computer has joined" is checked.
Also, you may want to try playing with the "Energy Saver" Settings in System Preferences, perhaps disabling sleep mode but turning off the screen (although I don't prefer this method since it kind of defeats the whole purpose of having a sleep mode IMHO).

IMac and internet connection issue

Dear Forum members,
I have a number of iMac's. However on one of them when a try and connect to a certain site, I get "Safari can't connect to server" message. It also says safari can't open the page "http://www.somewebsite.com/" because Safari can't connect to the server "www.somewebsite.com".
Please note www.somewebsite.com is just a made up name.
When I googled around it seems to indicate a firewall is blocking this URL. So I did the following:
Make sure OSX firewall is turned off - it always was.
Tried to flush the cache by typing dscacheutil -flushcache but to no avail.
Tried accessing using Firefox - same result
Any suggestions on how I can fix this issue.
I am running OSX Version 10.7.2, Safari 5.1.2
Thanks
Max

Everyone I found the answer after I posted my own comment re localhost...got me thinking.
I checked /etc/hosts file and in there was a loopback to localhost
127.0.0.1 somewebsite.com
WOW...how the heck did that get entered as I never edited this file??
Now all works fine.
Thanks everyone for your assistance.
Here is a link to where I originally found the clue

Imac loosing internet connection

Have had iphones/itouch/ipad connecting to my home wi-fi network without issue for long as I can remember.
I purchased my first apple computer/imac this past week. My apple computer/mac knowledge is limited........
I connected the imac to th wi-fi out of the box without issue, however it seems to loose it's connection from time to time, sometimes it re-connects sometimes it does not. I thought it may have something to do with the mac going to sleep too often & failing to re-connect when it wakes, so I extended the time before it z's but do not believe that fixed the issue.
Not comfortable changing anything on my own without getting some guidance first.

Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 5
Reset the System Management Controller.
Step 6
Reset the PRAM.
Step 7
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
Step 8
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Internet connection cuts in and out, only on iMac 2.8 Duo, not MacBook Pro

Problem started 2 weeks ago
Only on my new iMac, my internet connection disappears randomly, without any problem at the same time on the laptop or iPhone, and with no loss of Airport function/connection, only the internet and mail access is lost, and only on the iMac. I tried changing location, no help. Reboot the Airport, no help. I ran the newest Disk Warrior and did other checks on my system, and it all checks out OK. It's easy to think that things do help at first, b/c the connection comes and goes, seemingly at random.
I found a temporary, reliable fix - open Network diagnostics and just go thru the dialogue boxes. The first window always shows green lights for Airport, Airport Settings, Network Settings, and ISP, but "Internet - failed" and "Server - failed" and by the time I go thru each window, it's fixed, and the outbox empties and Safari opens the page. The problem is, then, an hour later or so, it's all lost again.
Please help!

Just to clear this up so there's no confusion, there are two different things called Airport Extreme. The physical external hardware - wireless router, and then there's the internal wireless card inside the iMac, which is also an Airport Extreme card (you'll see this if you go to "about this mac" and select the hardware button - wireless card). I do not have the Airport Extreme external wireless router. I'm using a Motorola SBG900, and others have had this problem with D-link wireless routers. The recent software update for Airport Extreme has messed with the settings of the internal wireless card. If I go to Airport Utilities, it's looking for the external Airport Extreme router's settings. When you configure yours, are you configuring the external router, or the internal card's settings? My Airport Utilities stays blank when I open it (assuming this is because I use a 3rd party wireless router). Can you confirm that you're using the Apple Airport Extreme wireless router?

New iMac wireless internet crashes repeatedly -- why?

Just set up the following wireless LAN: Netgear WGT624v3 wireless router as access point between a broadband cable modem, a new 27" iMac, a PowerBook G4, and a Canon wireless printer. Everything works great except for one thing: whenever I'm trying to use the internet on the new iMac, my internet connection crashes and I have to manually reset the modem and router. This happens when downloading a file even as small as 2 Mb. As you can imagine, this has become incredibly irritating, as none of us can get anything done on our new computer without me having to come over and flip a switch on the power strip to repeatedly reset the internet connection.
The Netgear router is about as old as the PowerBook (3+ years)--I see it's listed "EOL" (end-of-life) on the Netgear website, and I'm wondering if it may not be powerful enough to handle the new iMac? That's the only thing I can think of, since using the internet with the PowerBook causes no problems at all. I don't understand the subtleties of Airport v. Airport Extreme, 802.11b, g, n or whatever, to figure this out on my own.
Anyone had a similar problem and/or can confirm that the router is the culprit before I needlessly spend money on a new one?

Some things you can try, if you haven't already:
-Make sure you don't have any cordless phone base stations operating near your router.
-Are any other electrical appliances (like microwave ovens or fluorescent bulbs) operating when your wireless connection fails?
-Power down the router and the iMac, then restart each.
-Change the channel your router uses to broadcast its signal. You should be able to do this from the web browser interface most routers support.
-Check Netgear's support website for firmware updates. Some routers can be commanded to check this from the web browser interface.

If I download Mountain Lion on my MBP , can I use the same installer file on a different computer and continue the installation without Internet connectivity?

Hi Folks,
I have just downloaded Mountain lion on my Macbook Pro(haven't installed it yet) . My question is, can I copy the same downloaded Mountain Lion from the Applications on to an external hard drive and use the same on a different computer? I am having problems with internet connectivity right now, it would be amazing if it can be installed on the iMac without internet connection.
So is that doable?
Thanks in advance

And the 2nd installation would not require internet connectivity? Except , of course during the set up and the configuration of iCloud and location based services, which I can skip at the time

Lost internet connection..."A connection time out occurred"

I've read a number of recent threads blaming Lion for lost wireless internet connections. I wish my problem was that simple.
I have an AT&T furnished Siemens SpeedStream 4100 modem connected via ethernet cable to a Netgear 3500 router providing a wireless network. This configuration worked without problem for over six months serving an iBook G4 (OS X 10.4) replaced by an iMac (OS X 10.7) in mid August, Lenovo Thinkpad (Windows 7), iPhone 3GS, and occasionally a MacBook (OS X 10.5) and a MacBook Pro (OS X 10.6). Then last week my iMac lost internet connectivity and displayed a dialog box saying:
"Could not join NETWORK NAME. A connection timeout occurred."
At the same time, my iPhone lost its WiFi connection to my network, and could not reconnect; and the Thinkpad could no longer find my wireless network.
Thinking the problem was with the Netgear router, I substituted my 6 year old Apple Airport Express in the same configuration, but with a different wireless network name. (I had used this network setup successfully for over five years before replacing the Airport Express with the Netgear router in February.) The Airport Express network worked on both computers and my iPhone for a couple of days before I again lost internet connectivity exactly as I had with the Netgear router.
I called AT&T, thinking the Siemens modem must be at fault, since a problem with that one device seemed more likely than successive failures of two different routers within a few days of each other, or a simultaneous problem with a Mac, PC and iPhone. AT&T said their modem checked out problem free. I have now connected my iMac directly to the Siemens modem with an ethernet cable and have a problem free wired internet connection.
I need my wireless network. Any thoughts on what happened to my WiFi?

AppleSince86 ... we have this same problem with a wired version of 802.1x
It appears if a user updates their password (perhaps their login screen prompts this to do this)... the underlying eapolclient will still use the old outdated password to reauthenticate upon the next x min refresh interval.
This will basically kick the user off line.
Two things could really improve this process:
1) When the operating system reauthenticates for network access... use the absolute most current version of a users password
2) Timeout handling seems much more wonky in 10.7 / 10.8 ... could probably shorten all of the timeouts up a great deal... no need to wait 30 seconds error out... in reality... if you haven't heard back in 5 seconds, you're not going to.
Unfortunately, I haven't found any configuration files to control this from our end... it appears to be the compiled behavior of the apple code
