Does anyone else have problems with music steaming and high data download speeds? I use my Airport Express (2-gen n) as my only router. I also use it for music streaming to a HiFi receiver. My internet speed recently got upgrade to 100 Mbits. When download speeds gets high (about 4-5 MB/s) lags music playback. It does not matter if I'm streaming the music from my MBP or iPhone. When for example App Store is updating an application the music playback is lagging. The Airport Express have the lates firmware. I've also tried the older firmwares available for the router with the same results. My MBP is running 10.9 and iPhone iOS 7.
