Periodically, once or twice a day, I'll start to experience network issues (latency and dropped packets) on this one machine while I'm browsing:

ping results

  • Other machines on the same Linksys WRT54G wireless network continue to function normally
  • I've attempted shutting down all running programs that I can identify
  • I've attempted disabling and re-enabling the wireless connection and reconnecting to the network

The only thing that seems to fix it is restarting the machine. So that's what I keep doing.

My best guess is I have either have something running on the machine that I haven't identified causing this issue ... or ...?

Very open to any ideas on where to look or what types of things might cause this :)

  • I started experiencing the the network issues again. This time I was able to get it working again without restarting the air. I changed the channel on the linksys wrt54g from the default 6 to 11 instead. I was confident that the other machines on the network were working, but I must have been wrong. This might have been it. I will update again if problems persist. Nov 6, 2011 at 21:29
  • In any case, it's clear this probably isn't specific to the mac. I'll post what I find here in case anyone finds it useful, but the original question is likely wrong. Nov 6, 2011 at 21:31

I advise you to download and run iStumbler http://istumbler.net/ on your Mac. Run it around the place where you want to work and at peek hours of the day (where your neighbours are also using their Wi-Fi PC and routers).

This run should give you a clear indication of which channels are received at a high power level. You should absolutely avoid these overloaded channels (most probably 1, 6 & 11) and pick a channel which is either free or received at the lowest signal level where and when you work.
