No, Netgear DG834, the BBC iPlayer is not a Denial of Service attack

Netgear DG834If you’re having trouble with iPlayer on a mobile device over WiFi, this may be of some help:

I recently installed a Netgear DG834 ADSL 2+ modem router.  It works beautifully.

My other new toy is a T-Mobile Pulse Android phone.  A lovely bit of kit for not very much money.

Trying the excellent beebPlayer application (an iPlayer client for Android) I found that quality was far worse on WiFi than on 3G.  Surely that can’t be right?

To cut a long story short, the DG834 has a feature called Port Scan and DOS Protection, which as it turns out interprets the incoming RTSP packets as a DOS attack and drops most of them.  Switching the feature off (under Advanced / WAN Setup) makes it all work perfectly.
