IMac 333 stops connecting to internet

I have a Rev D 333 running OS 9.2. It is connected to a router that is connected to a DSL modem. Last night I was unable to connect to the internet, even after I played around with the settings. When I looked in the Apple Profiler, it gave the status of the ethernet as 'down'. I switched cables several different ways - used a different cable to connect to the router, connected directly to the modem. When connected to the modem, the number that represent the iMac's connection just flashes. I also tried changing various settings with numbers copied from the other machines that still connect.
I know this sounds stupid, but does this mean the ethernet card, or whatever it was called in this machine, is basically dead? My DSL provider, Apple, and the router manufacturer counld not help me.
Is it possble to replace that ethernet card? I have other, newer, 'better' machines, but this old iMac and it's old printer still produce that best pictures.

Safari stopped connecting to internet

Have used Safari for years. Stopped connecting to internet. Other browsers connect okay. I tried to get to the Network preference configure pane to change the proxy as I read here, but a dialog box pops up and blocks using the Network window. I click okay on it over and over, but it comes right back. It says"Your network settings have been changed by another application." I installed Safari again, but it didn't fix the problem. Firefox doesn't like my games. I want Safari back!

I'm having the same problem. Started sometime after I upgraded to Tiger (10.4.11). Tried upgrading Safari to 3.1.2 with no improvement. In trying to diagnose the problem, I've seen some weird things. e.g. I can always connect to secure sites (https). Sometimes Safari will work for a while after I've been using Firefox for some time. When I booted up using my old system, Safari worked just fine. But I can connect with Safari on my iBook while it is connected to my desktop (both use Tiger) going through the desktop's modem. I've already tried putting the DNS settings in but it didn't help. Only other thing I can think of that happened is that I stupidly joined Google checkout. Since them I've been inundated with spam and I'm afraid they put something on my computer and now it's messing me up. Am considering doing a complete system reinstall, but don't really want to since I'm not too hopeful that it will work.
Any suggestions would be greatly appreciated.

IMac unable to connect to internet

Hi. I had this problem immediately after installing the latest update. I was happily browsing the web and then right after I installed the latest update, I couldn't connect to the internet! Neither Safari nor Firefox, not even Yahoo Messenger works. The WiFi network's working fine - I am able to connect to the internet with my other devices. I am even able to use the internet with the Windows part of my Bootcamped iMac. Nevertheless, I've unplugged the modem and router for more than a minute, I've rebooted, I've run the network diagnostic tool (which said I am connected to my WiFi network) - still couldn't connect to internet. Please help!

Imac suddenly stopped connecting to network

sorry if this topic already exists somewhere. i've been searching these forums for an hour and can't find any useful help on the subject.
we bought our first mac almost 1.5 yrs ago. this beautiful 27" imac worked fine for 1 year and then suddenly stopped connecting to our wireless network. distance to the wireless router isn't an issue. doesn't matter where i move it to in the house, it sees the network, but won't connect anymore. 6 other laptops/video game consoles/pc's all continue to connect w/o a problem. this happened once approx 3 months ago and i figured our old router had kicked the bucket, so i bought a new router and it worked fine for several months and now it's happening again.
i've gone thru all the preliminary steps of unplugging the modem, the router, the imac, and renewing the dhcp but nothing helps. it will work fine if i wire it directly to the router, but i don't want to run a 75ft ethernet cable thru the house.
i'm so frustrated with this supposedly wonderful imac! can anyone help me?

Here's something to think about... I know my AT&T DSL Cable Modem will only allow a certain number of connections. A few years ago that might not have been an issue, but now with wi-fi cells, gaming systems with netflix, other laptops/ipads, you might be exceeding that limit. It could be they are all connected and you don't have a spot on the router.
This might be elementary, but thought I'd throw that out there.

IMac refuses to connect to Internet

My stepson has a G5 iMac that suddenly started having Internet connection problems today. For the first time, it said today that it had a self-assigned IP address and couldn't connect to the Internet. I tried restarting the computer, resetting the router, etc. Nothing.
So then I entered the IP settings manually, after looking at the router's administrative settings to see what IP address the computer had before. Even after I did that, and it said it was connected to the 2WIRE router, rather than having a self-assigned IP address, it still couldn't connect to the Internet.
If I went back to configuring DHCP automatically, it would give itself a self-assigned IP address and the whole problem would start again.
I cannot figure out what's going on here. Anyone have any ideas? I haven't tried connecting it directly to the router because I don't have an Ethernet cable that's long enough. Yes, I can go get one, or I can move the iMac temporarily to try out the Ethernet connection, but I wanted to see if I can solve this without resorting to one of those things.
Thanks!

We have 3 other Macs, including an Intel iMac that's connected via Ethernet and a MacBook and an iBook that are both connected via AirPort. They're all working fine. My stepson also has an iPod touch that can get on the Internet through the router.
I was wondering if there's a problem with the router, but I don't understand why it's affecting his computer and not the others.
Last night, my stepson was able to connect to a nearby unsecured router that had a weak signal. He was able to surf the Web, albeit slowly, so I'm wondering if it is indeed the router, which is also my DSL modem. But I still don't understand why it's affecting him and not the other computers.
Thanks for your response.

Imac won't connect to internet

Hello,
My iMac will not connect to the internet correctly. I know the internet is working because my wife is using her laptop wirelessly, and my software updates are still working.
Some pages open, but are corrupted and not laid out correctly, (amazon and BBC News). I have tried to connect wirelessly, and failed. I have emptied the cache and reset safari. I have tried firefox and the same thing has happened.
Any suggestions would be greatly appreciated.
Thanks
Tim

Computer stopped connecting to internet even though there is full signal and nothing has changed.

so the other day i opened my computer and it wouldn't connect to the internet. it had been working fine before that and nothing had changed, it just stopped connecting. I have full signal and can connect to the network, but my internet signal on the top bar has an exclamation point and says "Alert: no internet connection." My roommates can both connect with their computers so i dont know the problem! i've looked for soulutions on other forums and havet tried deleteing "airport" as a source and then re-adding it, deleting the system configuration folder (a suggestion someone got from apple), renewing the DHCP lease, nothing works. help!

My iMac can't connect to internet wirelessly

I purchased a 27" iMac in 2013 version 10.8.5. For no apparent reason, my iMac won't connect to the wireless. According to my iMac I have full bars but when i open my browser and try to connect to any website, the page won't open. The browser continues to try to load page for some time and eventually displays "Safari can't open the page "http://<website address>/" because the server where this page is located isn't responding." I had, prior to this problem, and still have, after this problem, other devices connected to the same wireless router without problems. My current wireless router doesn't have a password, however, there are no neighbors close enough to connect to my wireless router. I've restarted my computer, shutdown my computer, restarted my wireless router, turned on/off Wifi to no avail.
Per System Preferences>Network>Wifi, i have a green light with status: Connected. My Airport Utility however switches back and forth between connected and not connected. But regardless of what my Airport Utility says, I can't access wireless. I'm looking at the IP address and my macbook pro is connected to the same IP address without any problems. Does someone know what's going on?
Please help!

Hello, littlemold
Thank you for visiting Apple Support Communities.
I see you have already processed most of the relevant troubleshooting steps for this issue. This could be related to your router assigning a self-assigned IP address. I would recommend going through the steps in the article below.

IMac suddenly stopped connecting to the internet

So, I left the room for a while and let the screen saver come up, when I came back it wouldn't connect to the internet with any program (iChat, Safari, Firefox, and Thunderbird).
I connect via ethernet to FiOS but none of the other computers are having trouble connecting.
It's not a connection problem, thankfully. I connected my ethernet cable to a laptop and it connected perfectly.
I ran a diagnostics, however it was essentially useless. It told me that it could not connect to the internet or the server, and to check to make sure that the URL was typed correctly... No websites will load, though.
I did ping my mother's laptop (and my own computer) and it came back fine again, again and again...
In my limited opinion, it has to be some sort of software problem, but this being so all of a sudden bothers me. If I were on a PC I would think virus, but since it's a Mac, this is not likely at all.
Please give me some help and ideas, cause I have run out...
Thanks,
Mike.

I used to have the exact same problem, after I cleared my dns cache and renewed my DHCP license everything worked. Strange thing is that, somehow, someway, by some form of magic this problem stopped happening all together so I never had to continue issuing the command everytime. Could've been due to an update shrug
Type the command below in a terminal. Then renew your DHCP license in Network settings
-> sudo dscacheutil -flushcache

IMac won't connect to Internet after trying to download mac so x

So I was trying to download Mac OS version 10.6.4 (the CD that came with my iMac) and about fifteen minutes in it stopped and restarted. Well I didn't think anything of it because I was late for work as it was. I tried to get on today and my iMac is super slow, it won't connect to the Internet, and IF it does it only stays connected for about 10 minutes. What's wrong? What can I do to fix it on my own, the closes store is two hours away and I really don't want to that?

As we say back home you really screwed the pooch. OK Put your install disk back in and restart the computer while holding down the C key. This will start you up from the disk so you can access Disk utility from the installer program. Click the first aid tab, select your drive and run repair disk.

Brand new IMac can't connect to Internet while using Vista Ultimate

The subject is pretty much it, but basically. We just bought a brand new IMac and I happened to have an old copy of Windows Vista Ultimate lying around and wanted to partition some hard drive space for gaming. During the installation a message popped up that said Lion only supports Windows 7. I went through with the installation and after Windows started I loaded in my old Snow Leopard CD. I installed the drivers and went through the set up. Everything seemed fine, but I am unable to connect to the Internet. I plugged my desktop in via Ethernet to my router but still no Internet. In my device manager there are many devices, including network controller, that have yellow exclamations next to them but I don't know how to update them or where to get the drivers. Any help would be greatly appreciated, and I would be happy to take any steps to relay more information. Thank you!

New motherboard. So unless you can find, and want to mess around, which is why the pdf guide and all the faqs tell you what and how to install, and that only 7 is supported.
Vista SP1 is no longer supported even by MS.
You have Sandy Bridge based system with Thunderbolt, hence it needed new device drivers.
Windows 7 64-bit SP1 Home Premium System Builder is $95

IMac G3 problems connecting to internet.Updating software

I bought an old iMac G3 running Mac OS 9.2. I can not figure out how to connect it to the internet using ethernet. I have at&t internet with wireless and all that. But the operating system is so old that im lost fooling with it. Can anyone help. Also id like some advice on how to update the operating system to the lastest version that would run on this computer. Any advice would be great. Thanks

Mike,
Welcome to Discussions (or is it Apple Communities that we're meant to call it ?)
OS9.2 on an iMac G3 should work fine for simple internet stuff. You may want to upgrade to somethng like OSX 10.2 or OSX 10.3, but the cost of required memory upgrades, perhaps a bigger hard disk and then the OS itself, may mean it's more efficient to to sell it again and buy an old iMac G4 or an eMac G4. These would be much faster and may already come with enough memory and disk, and maybe even with the OS. eMac G4s are pennies on eBay, if you buy on the right day (ie. not Sunday night), some sellers still try to command £70 / £90, but if you wait you can get one for £10 or top-of-the-range for £40.
Still, stick with the iMac G3 for now and see how you go.
So to get internet working o Ethernet ...
Firt thing to know is that OS9 and earlier are a real pain at detecting when an active connection over Ethernet appears.
So first thing to do is make sure the iMac is connected by Ethernet to the hub/router with a 'patch' cable, as opposed to a 'cross-over' cable. If you're unsure which you have it's probably a patch cable, but if you can try another cable, do so.
This is because the iMac G3 doesn't come with an auto-sensing Ethernet port, like all the G4s and all Macs aftr that did. An auto-sensing port can detect when a cross-over cable is inserted by mistake and make it work anyway.
Once the cable is in and the router is on and working, then start up the iMac.
In OS9 you're going to need to configure the AppleTalk and TCP/IP control panels.
AppleTalk first, make sure it's On, and selected to connect over Ethernet.
Then TCP/IP, select it to connect over Ethernet and to get everything from the router, ie. DHCP, everything else "suplied by router".
Start up Internet Explorer and go to google.com or something, then open the TCP/IP control panel again.
Does it have an IP address assigned ro you ? and a mask ? and a router IP addess ?
Hopefully it'll say your IP address is something like 192.168.x.x, Subnet Mask at 255.255.255.0, Router IP address at 192.168.x.x. And the Internet Explorer window has loaded google.cm for you.
Less helpful is if you still have no IP address in the TCP/IP control panel. This means TCP/IP has not started.
A dead loss here is that the IP address assigned to the iMac is something like 169.x.x.x, a self-assigned IP address that means the iMac cannot communicate at all with the router.
Or do you have some other IP address ?
If you don't have immediate success, try a restart and start Internet Explorer again and open TCP/IP control panel to check your IP address again. The restart is because, like I said before, OS9 is awful at detecting a new connection - there is a fix for this, but lets get the internet working first.
Post back what you tried and what happened and any errors you got. Don't be vague, the more complete and accurate the detail the waier it is for those here to help you get it working in a few minutes.

IMac can't connect to internet dial up after start up.

I've a problem every time I try to make a connection to the internet directly after starting up my iMac. The very first time I try to log on to my ISP the Mac appears to make a connection, the status window in Internet connect indicates that it has (generally 52-54000bps), but when I try to surf, my browser can't find any sites, same with email. I get the standard connection noise when dialing out, occasionally the noise drops out mid way through, but it always makes a connection. Sometimes it will disconnect after about 30-40 secs, sometimes it doesn't. When I reconnect a second time I get good speeds and can stay on for hours. This is happening every time I boot up and dial out, basically I now expect to have to dial out twice before I can get onto the web every time I switch on the computer.
I've read a few threads re this problem, it seems the iMac has a software modem which can cause some problems, but there doesn't seem to be too many complaints about this exact same issue. Should I be getting a Mac tech to sort this out or is this a generic issue that may be resolved in a future software update? This is a new Mac my second as the first nearly flew out the window after a kernel panic. Apple tech support in Sydney don't seem to have heard of this problem, and have told me to re install the OS again, which of course I have, plus run disk aid and re set the permissions etc etc...
The ISP has given me an alternative dial up number which actually works the first time I dial in, but I only get speeds of 28000bps. Can anyone shed any light on this? Will I get a similar problem if I went to Broadband?
Thanks for any comments...

Unfortunately I've not got any help on this issue. An Apple tech has told me to try changing the modem settings down to V34 which I did, the connection worked correctly but I was only getting speeds of up to 33000bps, real speed tests showed I was actually only on 28000bps, same as when I dialed the alternative number given by the ISP, not good enough. I don't have any other devices connected to the phone line, in fact the line is only used for the internet. Maybe there is a problem with this type of software modem, but then why isn't there more comments here, unless everyone else is on broadband. Apple and my ISP seem to think the slower connection is more reliable, it is but at a cost. Not sure why this is considered better when the speed is so slowww. Like Seb above I don't have any problems when I'm using a Windows lap top on the same line.
Anyone out there know the answer??? There are at least 3 of us with this problem...

Airport stopped connecting to internet - ethernet cable OK

Last night, my wireless stopped working. When I looked at the network diagnostics, it had everything fine up to and including the ISP, but then it couldn't find the internet from there. I rebooted my modem but to no avail. I then tried just connecting the ethernet cable to my mac and that was fine (once I'd rebooted my modem). However, I still am having problems with the airport. I tried a restore to factory settings but I still can't get anything. Has anyone else had this issue?

I know that you have already tried a number of resets, but I would recommend that you try the following:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.
