i have iMac (21.5-inch, Late 2012) and have recently upgraded my internet to 350 meg line...
When i do a speed test on my iphone my download speed is averaging around 384mbs..
On my mac i only get 280mbs and a little faster if i use ethernet cable...
Can this imac handle 300meg and over or is it limited to 300meg...
The imac is updated to High Sierra....
iMac, macOS High Sierra (10.13.3)
iMac (21.5-inch, Late 2012) has Airport 802.11a/b/g/n (450 Mbps using 4 coupled antennas) wireless and ethernet 1000Base-T wired (1000 Mbps)
Your iPhone likely has 802.11a/b/g/n/ac wireless (433 Mbps per antenna (probably 1)).
Note: these are theoretical maximums; only for advertising purposes. Configuration, Wi-Fi protocol, overhead, distance, interference, shared bandwidth, and other limits in the chain can diminish this.
A firmware update might tweak a certain protocol a tiny bit to conform better to a certain standard, but it won’t magically upgrade the hardware capabilities.
Of course if you have any anti-virus programs with real-time scanning that would drastically affect the results along with running a VPN etc.
Any available firmware update for your iMac would most likely have been installed long ago.
There are soooooo many variables in this that you could spend a lifetime tracking them down. Is it fast enough? If yes, forget about it...
all i want to know really if the imac is capable of higher speeds...or would the hardware need a firmware update...
