Honesty some further vetting of these hints needs to take place. There's been too many recent 'hints' that end up not being what I'd class as hints at all.

I'd have thought Mac OS X Hints is not so much a tech support repository, but a repository for tried and somewhat tested, genuinely useful, hints.

General troubleshooting of tech, where there are specific, or indeed multiple possible causes and multiple fixes is probably not the best use of Mac OS X Hints.


Anyways.... some thoughts on this 'hint' specifically.

The crux of this hint Author's issues are just general network issues. Not specifically a problem with the ipad or Airport.

In general this is either a problem with bufferbloat (google it, rather technical issue facing many routers), tcp session table overload (on the Airport or Modem) or Double-Nat issues.

Just quickly (as there's a lot more to it) bufferbloat relates to over provisioned or over sized buffers along the connection between the end device and the host from whence a stream of data is requested.

The buffers quickly fill up, giving the impression to an host that the connection is quite quick, so it starts sending data quicker and then runs into issues.

You then see the symptoms (at worst) of stuttering video, ping jitter, dropped connections, or at best much much slower connections for the remainder of the session as the buffers drain.

I'm not an expert, but hope this sheds some light. Charlie.
