Sometimes it works..


.. and sometimes it doesn't. Connections problems with iChat

Today, during my weekly video-conference call to the UK, iChat stopped working. In fact, it stopped working before my weekly call - it just wouldn't connect. The other party was told I wasn't responding, and I was told the other party wasn't responding. And yet the exact same set-up worked perfectly the previous weekend. Neither network had changed, but iChat stopped working.

Obviously, something, somewhere must have changed, so it was time to experiment. The "not responding" part made me think of a router not forwarding information to certain ports, so I set my home network router to put my iMac in a DMZ - in other words, the router would pass everything no matter what. I then talked the other party into doing the same.

No difference.

Then I tried limiting the bandwidth, audio-only calls, turning off the Mac OSX Firewall - you name it, I tried it.

Disappointed at this stage, I warned them to disable their DMZ setting before switching off, and amazingly they decided to try once more to establish a connection and boom! - it worked.

I can't see any logic to this, other than maybe a bug in the router (a Linksys WAG54G) that needs an option changed to reset itself, but anyway, it worked. Maybe if you are having problems connecting, turn on and off the DMZ options on your router and hope for the best.

Also, keep your eyes peeled for the next Mac OS update to 10.4.2. Rumour sites have this one down for a hefty update that includes serious enhancements to iChat as well as other general OS features. It should be out very soon. Perhaps even this coming week.

Let's hope it improves the connection reliability with petulant routers.
