I've got a PS3 and

Question

I've got a PS3 and it runs by wifi to a Linksys router. I have no problems connecting to PSN, playing games online or downloading stuff from the PSN store. The problem is whenever I start a game that needs a update downloading and I choose to download it it'll start downloading it then freeze at about 6% then an error message will come up after a while of it being stuck at 6%. However after a few trys before it starts to download the update but after it's left the game it has a please wait screen that lasts longer than usual then it downloads perfectly.Does anyone know how to make it download properly?Please don't tell me to use a ethernet cable because I've tried that.Also refrain from using router jargon.Thanks
