[QUOTE="rlvdijk, post: 995465, member: 143199"] Hi, Actually, I don't know where to start. But let's explain my setup first: My iMac (wired) and AppleTV (wireless) are connected to the Time Capsule (802.11n, 5Ghz) My girlfriend's MacBook and 2 x iPhone 2G's (wireless) are connected to an Airport Extreme Base station (802.11b/g compatible). The Time Capsule and AEBS are connected and show two different networks. Now the problem: When I copy files from e.g. the iMac to the MacBook or to the Apple TV, it's very slow. I've used scp to copy a 200 mb file and it took about 1.20 minutes (at 2.5MB/s). I've did the same when the iMac was connected over wireless and it took about 3.45 to 4.30 minutes (at 1.0MB/s). I'm not sure if this IS slow, but it certainly feels like it. 802.11n should be around 100 Mb/s in practice and 802.11b/g around 20-25 Mb/s. By the way: downloading from the Internet is excellent, I get the full download/upload speed my provider offers for my subscription. Second, I added the signal strength/noise levels for the Time Capsule attached devices. They vary around -68Db signal, -90Db noise. The question is: are these levels normal ? What should be higher or lower ? Thanks in advance ! Rutger [/QUOTE]
