Hi Josh and Sean We need to be a little careful here as we are in danger of straying off topic, :). Sean raises some very good points, and his diagnostic suggestions are well-founded. There is one other thing, however, which you could try in order to nail this down. If you are using wifi networking, try doing the same thing with an Ethernet-based network connection. If your wireless connectivity is only Wireless-B/g, check to see if your router supports the more standardised and much more efficient Wireless-N. I believe that you're in the UK Josh. So if you're using BT Home Broadband or Virgin Media Broadband, you should have a wireless-N compatible router as that's what they issue their customers with these days. I can't comment regarding other providers such as Sky or Talk-Talk, but since both Sky and Talk-Talk actually use Tiscaly Broadband at their core, they probably do.
Be aware that by default, Mac OS X only permits one single IP connection at a time … meaning that you couldn't specify to use wifi networking for one thing and wired networking for another. In order to do that you would need to replace the IP stack mechanism in OS X. It can be done, but it's a little tricky. BSD is the base of Mac OS X and you'd need to either use a re-compiled IP stack, or else use a utility such as the one we use, (IPNetrouterX) to modify the IP stack behaviour of OS X so as to allow two simultaneous connections using the same protocol but using different adapters. Again it's quite complex and I wouldn't for a moment pretend I have a clue as to how you'd recompile the IP stack. That's why we use a third-party utility. They replace the IP stack with a UNIX standard one which does allow multiple IP circuits simultaneously and then their GUI simply lets you define which traffic (based on port mapping), goes to which adapter. Simple principle, really, just a bit difficult to implement.

If you are doing a lot of other traffic at the same time as your Skype. Then you might not have enough band with to be allocated for Skype. Thus, you get choppy speech being sent. or received. Your ISP might have some Quality of service (QoS) configured on their routers/switches not correctly handling Skype protocol. They might be treating Skype as a generic protocol meaning you are competing with all other general traffic on the ISP network. Another possibility is Skype has band width issues which I find very unlikely. If your router has the ability, I would configure QoS on it and try and allocate dedicate band width for the Skype protocol. I am not going to explain how to configure or the concepts of QoS because it is a subject of its own and beyond this list focus. A tip to trouble shoot on your Mac, I would suggest you do not have any other programs open that access the Internet. If you are sharing the network with others, stop them from using it as well. Basically, I you should be the only person using the link and Skype should be the only program. Then make a Skype call and see how it performs at similar time as the previous times you had poor quality. The final point is you might not be able to do anything about the quality because your router doesn't have a advance enough QoS. I would suggest talking with your ISP and see if they are doing anything unexpected with the Skype protocol. Be aware, if they are, they might not change their business policy. <--- Mac Access At Mac Access Dot Net ---> To reply to this post, please address your message to [email protected] You can find an archive of all messages posted to the Mac-Access forum at either the list's own dedicated web archive: <http://mail.tft-bbs.co.uk/pipermail/mac-access/index.html> or at the public Mail Archive: <http://www.mail-archive.com/[email protected]/>.
