Recent inability to perform an audio IChat

I have been using IChat (audio and video) for years to connect with my daughter overseas. Recently I am unable to connect to her and others via IChat (text chatting is still working). Weirdly enough, there is still one person I am able to audio chat with. For the ones that I am unable to connect to I'm getting an -8 error. I have been using an Airport Extreme bridged with two Airport Expresses all along.

About a week ago Embarq sent me a new DSL 660 series router because my previous one (a 645 series) shot craps. I believe the new modem or it's settings is the cause of this problem. I had previously had the Airport set to connect via PPPoe. Embarq's instructions for setting up the 660 series modem involved changing the connection to Ethernet using DHCP.

Everything about the internet, email and ICHAT text works, AUDIO and VIDEO do not work.

Any suggestions? I really need to hear my daughter's voice again.

15" G4 Powerbook 1.67 Ghz, Mac OS X (10.4.9)

Hi,

It sounds like you have been sent a Branded Zyxel device.
See here for Login info http://portforward.com/routers.htm As you can see there are several variations under Zyxel.

Go to iChat > Preferences > Accounts > Sever Settings Tab for the account in question.
Change the Login port to 443 (currently 5190)

If this does not work we will need to know if the Modem and the Airport Base Station are both doing DHCP to the LAN

Resetting the port didn't allow the audio chat to go forth. I got the following error log as before:

Hi,

I gave the Port Forward.com link to allow you to see if the Logon info worked for your device.

I also asked you to confirm which devices were now acting as DHCP server ?

Thanks for getting back to me.

I'm going to have to work through the port forwarding at the link you sent. It's totally new to me and I'm concerned I'll screw it up so bad I'll knock myself offline entirely.

How do you determine which devices are acting as the DHCP server?

The link http://portforward.com/networking/static-mac10.4.htm asks me to enter my computer's default gateway. I don't know what that is or where to find it.

It also asks for my computer's current IP address. I don't know how to find that.

The Network panel on the instructions doesn't include an Airport tab which mine does because I'm using Airport connected by Ethernet to the DSL modem. The instructional panel shows the TCP/IP panel selected. Should I be selecting the TCP/IP tab to make the suggested entries?

I may appear a dullard but I've just never done the bit fiddling being done here.

Hi guitarbruce,

AT this stage I am not asking you to change anything.

I am asking you to Login to the Web pages on the Device and tell me if it says it is doing DHCP.

AS an Example This pic shows a Linksys page (well actually it is the bottom of one) AT arrow 2 it shows the DHCP server in this device is turned off.

With an Airport device you need to open Airport Admin Utility in Applications/Utilities on the Mac.
It should say it Sharing an IP.

Oct 17, 2007 12:56 PM in response to guitarbruce

OK,

I will answer this one as well. (While waiting for the other info)

Open System Preferences > Network.
Choose the connection method in the list or the second drop down.
Click on the TCP tab to make sure it is the active one.
Series of Pics

The Last pic Shows my set up is already set to Static.
Yours probably says "Using DHCP" in the drop down that reads "Manually" (Static) on mine.
Your IP is most likely coming from your Airport at the moment. It is most likely going to read 10.0.1.x
The "router" IP further down is the is one Gateway and in this case is the Airport (10.0.1.1) (Although the default for your Airport could be different.

Now in the Airport Admin Utility you will find the info for the Airport to Modem connection in the Internet tab.
It may or may not List the "Gateway IP" of the modem or the DNS servers or Subnet Mask if it says it is getting an IP Automatically (DHCP)

In Fact the "gateway IP" will be the IP you use to access the Modem through the Web browser.

In the Modems set up pages you should (hopefully) get told the IP it is using, The Subnet Mask, and the DNS servers (Unfortunately some devices do not list/show the DNS servers)

Once you have confirmed that the new modem and the Airport are both doing DHCP you will have a choice.

1) Turn off the DHCP server in the modem
Set the Airport Internet page to Static and fill in the Boxes (YOU MUST Have the DNS server info to do this)

2) Change the Airport to NOT SHare an IP as this will turn it into a plain Wireless Access point.
Effectively it turns Off the DHCP server here and allows the modem to issue an IP to your computer in a way that shows up in System Preferences > Network.

At present the computer is getting two IPs (If both are doing DHCP) and one is hidden.
See lower Pic. This is a slow to load/Process Animated .gif (Slow enough to read).

Hopefully this will explain things a bit more.

Hi Guitarbruce,

Yes.

It does not list the DNS servers so turning the Sharing IP Off in the Airport would be the easiest way to go now.

We have two laptops in the house using that airport, as well as the 2 Airport extremes that are bridged to it. I also have others visit with computers that use the Airport internet connection. How would that effect them if sharing was turned off?

Would it be helpful if I called Embarq and found out what the DNS servers where?

What would have changed from my old modem to this new one that made it no longer work when plugged in?

Hi,

If the Expresses are set or were set at set up to "Join an Existing Network" what you are doing is doing the same thing for the Base Station. (joining the Modem's Network)

It should not effect the set up of other items and devices.

Errr....

Open Airport Admin Utility.
Go to the page/pane where it says it is Sharing an IP.
Turn it Off.Apply/Save settings

The Mac(s) should now show an IP from the Modem.

The only way to de-select (turn off) sharing is to un-check "Distribute IP Addresses".

If I do that how will it affect the other computers?

What is "Distribute IP Addresses" for?

Answer 15

Oct 17, 2007 2:31 PM in response to guitarbruce

Hi,

DO you have Tabs like the fourth pic ? (THIS LINK IS FOR LOOKING ONLY)

If so then it is in Network and it is a radio check box for Distributing Addresses (Doing DHCP).
It needs to be Unchecked.

This will turn off the DHCP sever in the Base Station.
Wonderful little Apple device that it is this will change it's function without need of further set up.
It will allow the IPs issued by the Modem to pass though to the computers and other Airport devices.

It is then acting as a Wireless Access Point (Not a routing device). Just like the Airport Expresses are currently doing.

As the Laptops and the Airport Expresses are already set to get DHCP Issued IPs, from what server device is giving them out, they will see the Modem's DHCP server now (with no further set up) rather than the DHCP server in the Airport.

Providing the computers are set to "Using DHCP" then they will not be effected other than the time it takes the Airport Base Station to reset and allow the Modem's IPs to be picked up.

Read the bottom post.
