I have this issue when streaming music from my PC. It doesn't stutter so much as it just stops every once in a while (at random intervals) to 'catch up' or something. I was unable to change my Airlink wireless N routers transmission rate unless I backed it down to only run as a G router. I've tried 18mb/s, but it still stuttered, I'm about to try 12, and then 9 to see if it works. No luck so far.'
Transmission rate all the down to 9mb/s and still have the music stop for a second, and then keep going. Not sure what to do now. Any suggestions? The only thing I can think of is have another wireless router near the PS3 as a bridge, and plug the PS3 directly into it, but then I have to buy another router.
