Mac mini (2.4 core 2 duo, 10.6.8) has served well for years. Now it seems to be having wifi connectivity problems with no rhyme or reason to their appearance. Several other devices (laptops, phones) on the same wifi network can all connect and use the network with no issues. Sometimes connectivity is dropped altogether and later re-establishes. More often it just becomes impossibly slow:

64 bytes from icmp_seq=293 ttl=64 time=3.668 ms

64 bytes from icmp_seq=304 ttl=64 time=393.798 ms
64 bytes from icmp_seq=306 ttl=64 time=21.682 ms

Above, is our router. From another device, during the same time window, I see much more consistent ping times.

I tried to log all the wifi activity (sudo ./airportd debug +AllUserland +AllDriver +AllVendor; sudo ./airportd logger), and during the outage above there were no log messages seen. Wifi was "connected" but no data was flowing. The other issues (when the connection drops completely) I have not yet reproduced while debug logging.

Is there some other way I can investigate this problem, or should I just give up, assume the interface is dying, and buy a USB wifi dongle?

  • Could you also publish the Console log during the outage.

Sometimes that is caused by WiFi Chanel overcrowding.

Try changing the WiFi channel for Mac Mini.
