QOS at the customer end does not seem to fix this.

Would QoS / 802.11p fix this?

Online gamers using Telecom's entry-level Jetstream Starter connection are
venting about a hardware upgrade that is threatening to end happy days of
simultaneous web surfing or file downloading during game play.
As part of its move to a "next generation network" Telecom is replacing its
mix of largely Nokia branded routers with equipment from Juniper Networks.
The new routers more effectively handle internet traffic by queueing packets
of data that cannot be sent through in one go due to the limited size of the
internet connection at the receiver's end.
etc etc etc

I guess it's a difficult decision, because on one hand, you want to buffer
the packets that would normally be dropped so that the sending end doesn't
have to timeout and retransmit and slow things down further... this is "a
good thing" for TCP traffic, but on the other hand, you introduce delay to
time sensitive traffic as it has to wait for anything in the buffer to empty
before proceeding, which can be "a bad thing".
If the IP DSCP field is honoured, then realtime traffic could be made to
jump the queue by having DSCP set to expidited forwarding.. but given how
paranoid some networking equipment can be, I wouldn't be surprised if a
packet's DSCP value gets silent cleared as it passes across the internet.
Any technical comments or throughts on this from the list ?
