Are you saying that with 10.4 you had internet access on the iMac and when you upgraded to 10.5 you now don't?

Or

Are you saying that your router will not give you an internet connection because there is a problem with its settings?
 
The iMac is new, when i bought it 10.4 was already installed and i only had it for a couple of days before installing Leopard, during this time i didn't connect to the internet as the modem i used with my pc is a usb one so was unable to use it. I have since bought a wireless router so both that and the iMac are new. The router settings, according to my ISP Tiscali, are correct yet the message i get is that they are not.

I hope i'm making sense.

Thanks

Thanks, but i have spoken to them and they confirmed that all the settings i have entered are correct. They told me to contact mac support which is what i will do tomorrow.

Thanks for your help though.

If you cannot get any internet connection on any computer then its definitely the modem. There should be lights on the modem telling you what its status is (you may need to get the manual out). I don't think that getting MAC support will solve anything, although you could give it a go.

I have read a thread here : http://forums.vnunet.com/message.jspa?messageID=701833 where some people were having the same problem with Belkin modems and Tiscali internet. One person returned the Belkin and purchased a Netgear instead and it worked immediately. I must admit that I have only ever used Netgear and Linksys modems.

Good Luck. Let us know how you get on.
 
I think it must be the same problem as the lights onthe modem are fine for ADSL, etc, but for the internet one flashes blue and then amber. I'll try to install it on my pc this afternoon to see if the problem also exists there. I'll update later. Thanks
 
Hello

I hope you don't mind me adding to this thread but i also am having problems connecting the internet from my iMac.

I have a wireless Belkin router connected with an ethernet cable, this has been set up and has a green light next to Built in Ethernet in Network Settings, when using the diagnostics tool to try to figure out the issue, the ISP also has a green light, but not the internet. The router seems to be connected to the mac but is then not connecting to the internet. When i use the system assistant it tells me that my ISP won't accept the settings. I have checked my settings with Tiscali and i have entered the correct ones so am at a loss as to why i can't connect.

I bought the iMac with OS 10.4 and have recently installed 10.5, could this be the problem? Would it be worth going back to the original OS to see if that works, and if so is it as simple as just inserting the CDs.

Sorry for all the qs but i am new to Macs. Any help would be much appreciated.

Many thanks

Try rebooting your router by unplugging it from the outlet for about 10 minutes.
 
Thanks, i have tried rebooting the router to no success.

I have managed to successfully connect to the internet using the new router and my old pc so it can't be a problem with belkin and tiscali. Since setting it up i can also access the internet from my iMac using the wireless connection i just set up on my pc which is one step closer to what i want. However what i really want is to get rid of my pc and use the router with the mac.

I know now that it is not a faulty router and not an issue with the settings and the ISP so the problem must be with the mac, any ideas?

Thanks again🙂

NO THE PROBLEM IS NOT WITH THE MAC. It's the inability to convey the right information.

For example. What kind of modem? Phone modem? DSL modem? Cable modem? Is it pppoe?

What is the router set up? Did you use a "wizard" with the router? Do you have the information that you set up the router with?

Netgear usually makes the worst routers by the way.
 
I am using a Belkin N Wireless Router Modem.

I tried both the wizard with the router installation CD and creating a connection using System Preferences, Connections. Neither work for the connection to the internet.

Using the router wizard it selects PPoA automatically and also the VPI/VCI settings for my ISP (these have been confirmed by Tiscali as correct and work fine on my PC).

The literature for the modem confirms it can be used with OS to 10.4, however i am trying to install using 10.5 which is why i thought i might be best reinstalling the original OS.

Thanks for your help, i know very little about this and appreciate all suggestions.
 
The best way, in my opinion, to use routers is to do so using what the Mac already has; i.e. don't worry about install CDs and wizards because so much is done in the background that you have no control over and it'll be a mess when something goes wrong.

I would:
with the router unplugged,
In "System Prefs -> Network pane" remove all settings except the default set of Ethernet, Airport, Bluetooth and Built in Firewire.
Initially none should be connected and all dots should be red.
Keeping the prefs at the front, connect the wireless router with an ethernet cable. Alternatively, you can connect to it wirelessly by selecting the wireless network from the airport drop down menu in the menu bar or the sys prefs network window which appears when you have clicked on AirPort set of settings (incidentally the router should be plugged into the power and WAN/phone line all the time, and your airport card must be on as well to do this wirelessly).
When you do this you should see the selected network setting switch from red through amber to green in front of you. This might take 15 seconds or so. I personally always find this quite exciting.

When the setting says it is connected, click on its "Advanced..." advanced options button, and then go to the TCP/IP tab. IPv4 should be, by default, configured to DHCP (this protocol allows you to get an IP address from a DHCP server, such as a router, and means the process is automatic and you don't have to worry about typing in IP addresses for all the computers you want to use on the network); ensure this is so. Below are some groups of numbers, which as you may know are internet protocol (IP) addresses. The first one is that of your computer, the middle one (subnet mask) will probably be 255.255.255.0 but don't worry about that too much (it's used for more advanced networking when you want more computers to share a single IP address, but should be automatically assigned here), and the last one should be that of the router, and may well be 192.168.2.1 for the Belkin wireless n router. If this field is 0.0.0.0 or blank, click on the "Renew DHCP Lease" button, press OK and then Apply, then re-enter the Advanced bit and TCP/IP tabs where the new IP addresses should now be. If you still get no Router address, try it again, or either you are not connected to the router (so make sure the cables are all plugged in to the right places) or it has been configured not to be a DHCP server: this means you should reset it. Somewhere on the box will be a reset button. Press it, and possibly hold it for several seconds (whilst it is on) until the lights on it die and then come back on again. Then start this procedure again.

When you finally get a router address, what you want to do is copy that address (whatever it is) into the address bar of a browser window and load it and it should take you to the home screen of the router where you can configure it. If it is the first time you've been there the chances are you will be presented with a wizard which can help you set up your internet connection. Make sure everything is as your service provider (ISP) has told you, and then click apply or save settings or equivalent. Having done that, I would try opening another window/tab in the browser and loading an external web-page (I tend to go to google). If you've entered your settings correctly in the router page and applied them, then it should work, if not immediately then at least after a minute or so by which time the router will have had time to connect to the external server.

The crucial point is that if you can get to your router home page then there is nothing wrong with your Mac, and the fault lies entirely with the internet provider/router. Then you should start haranguing phone lines.

Unless your router is very unusual, this will work, and sorry if it doesn't!
Hope this helps a bit; good luck!
 
Many thanks for your very detailed answer, i'll have a go tomorrow when i have more time and will let you know the results. 🙂
