Couple questions but I'll stick to the main point: I am thinking of buying a Time Capsule or Airport Extreme. I like the printing and backing up features of these devices but the real seller would be whether I will see any improved performance on wifi-connected devices. So I'll list my situation and would appreciate anybody helping me know how I can determine if that will be the case. Will probably upgrade to rMBP this year and want future phones and ipads to be future-proofed as well. Would like help decoding what my system can tell me and any buying advice. Here's the current device situation: Chicago Comcast cable modem (no cable TV) --> connected to the Comcast-supplied Netgear Rangemax WNR 3500 v2. I can't find easy specs for that. Devices that use wifi: • My 2010 MBP (usually ethernet) • Wife's 2013 iMac (usually ethernet, but some Airplay mirroring) • PS3, PSVita • iphone 4S, iphone 4, iPad 1 (we do Airplay fairly often to ATV with these) • Apple TV current gen Here's a typical readout of my option-click of the wifi network. PHY Mode: 801.11n BSSID: (bunch of hex) Channel: 6 (2.4 GHz) Security: WPA2 Personal RSSI: -50 Transmit Rate: 130 MCS Index: 15 And some speed tests... MBP 2010 Speedtest on Ethernet: Ping: 9ms Download Speed: 23.99 Mbps Upload Speed: 4.18 Mbps MBP 2010 Speedtest on Wifi Ping: 22 ms Download: 5.0 Mbps Upload: 4.0 Mbps Thanks in advance, this stuff is greek to me.
