I start a full rate, SINGLE TCP flow to this remote system. The pingtime jumps up to 3 seconds! Yes, the stupid NAT box or DSL modem (notsure which at this moment) has a 3 second packet buffer, and simple FIFO behavior. Any full rate upload and I can kiss my connection goodbye. Period. End of story. Have a nice day.Fortunately, the Linksys _could_ be easily programmed to fix that -- and if the problem becomes obvious enough to enough buyers, the competition will fix it...
I disagree.I've had DSL or cable modem connectivity for damn-near a decade now. And fixing it is easy: the data rates are trivial, the devices are often programmable, and the solution straightforward: just have only 30ms of packet buffer, not 3s. Yet these devices STILL have this problem.
And the only reason that as a clued user it would be fixable if its the Linksys box is I DELIBERATELY purchased the version where I can replace the firmware to fix something the vendors refused to fix for themselves. And I just unplugged the linksys: its the DSL modem, purchased within the past 2.5 years.
(The reason its not a problem for me is I don't use P2P apps, and only rarely upload large quantities of photos)
So I think the conclusion should be there has been a market failure in this area, and that absent a miracle, this problem will remain.
