ps3 burnout paradise uses all internet bandwidth?

[RoganJosh]

Hi - stumped with this. My daughter is making the most of her free gifts from sony after the PSN debacle. Burnout Paradise was offered as part of the PSN+ free for 30 days - in the last few days she has been hosting games in the Freeburn Online mode - as soon as she starts, all other wireless devices are starved of bandwidth, while she can happily play away with maybe 8 or 9 other connected players.
I have my pc, couple of iphones, an ipad, the wii, the ps3 and a few mac laptops - I have never experienced this complete starvation of bandwidth before, despite using many several devices simultaneously. Also bandwidth from the dsl is fair with 8mb down and 448kb up.
Can I assume that the problem will only occur when my daughter is hosting a game? Is this a common problem? Is it just bad netcode from burnout paradise? And finally, when she goes offline - I need to reboot the router to get anything back online - including the ps3. Weird?


Any thoughts or tips appreciated.

if your daughter is actually hosting the room that could use up the majority of that up bandwidth, could also check the router isnt giving priority to certain common gaming ports (i've heard some do) like psn or xbox live
