Fault-finding a choked wireless conneection

Category : mac and the internet

I have been experiencing a very badly choked internet connection, so bad its slower than a 56k modem! This could be due to one of several reasons after digging through Macintouch, Netgear Support and other sites. I am unable to pinpoint when the trouble started so that made fault-finding more difficult. Starhub Maxonline being slow recently hasn't helped either.

I've ended up having to check everything.

  • 1. The system software - but the problem emerged in the middle of my use of OS X 10.3.7 (and carried over when I switched to 10.3.8); the usual maintenance checks didn;t help and other software was responding fine.
  • 2. A browser problem - I'm a multiple browser user and they are all crawling now.
  • 3. ISP - in this case Starhub Maxonline 6500. Sure it's not fast, and there are more users in the neighbourhood now which is supposed to help choke up their line. But since the iBook 1GHz (Airpot Extreme) is slower than iBook 600 (Airport), Maxonline cannot be not the immediate bottleneck.
  • 4. The Airport Extreme Card seating - it's seated properly.
  • 5. Firmware - System Profiler says the Airport Extreme Card firmware is version 3.3.2f3 (3.30.15.p8) and the Netgear Router Maintenance page indicates the firmware is V3.29(CF.0)b1 | 6/19/2002; seems up to date - only Germans seem to be talking about a Netgear firmware version 3.3 but the zip file links are outdated.
  • 6. Channel interference? - there are more networks detectable from where I sit, and the signal strength is less than 50 these days. A check with iStumbler reveals potential for channel interference but more signicantly, the noise and signal strength of my own network is bad:

  • 7. Netgear MR314 and Airport Extreme conflict - the wired connection at least works. This just got ruled out by No. 8.
  • 8. iBook antenna - could this be it? I just saw all the wireless networks in the area drop together in iStumbler.
