Should I upgrade the wireless adapter in my desktop computer to 802.11 a/c, or will I experience little real-world improvement over the current 802.11 n card? Here's what I'm working with... - Internet connection is rated at 25mbps/5mbps (cable) - Apple Airport Extreme (dual band n/ac) - Late 2013 rMBP with 802.11 a/c - Windows 10 Desktop with 802.11 n Although the internet connection is rated at 25mbps, the fastest download speeds I get when torrenting is about 2.8mbps over wifi. Curiously, this is the same whether I'm using the rMBP (with a/c wireless) or the desktop (with n wireless) -- if anything, the desktop is actually faster. This doesn't make sense to me since the desktop should be running on the slower n protocol. Can someone please explain what's going on here? The torrent isn't the bottleneck because I can get download speeds of 10mbps+ on the same torrent when I'm connected at work. The real question -- if I replace the wireless adapter in the desktop with something like the Asus PCE-AC68, will I experience any improvement in torrent download speeds or media streaming? Wifi coverage is a non-issue. Any advice would be greatly appreciated!
