If you're adding ethernet to the mac with a USB device, there is serious variance in the performance of them, some chipsets are barely able to break 100 meg despite being "usb 3" devices and linking at gigabit speeds.

 

 

Nope - not USB, Thunderbolt 3. The device I ordered apparently delivers up to 40 Gbps

There is a saying in the networking world - if it's fixed it should be cabled. 

 

WiFi is a complimentary offering - it is not a replacement for Ethernet and if speed is important then Ethernet will always win, in part because WiFi is also half duplex.

 

Depending on whether a device is 2x2:2 or 3x3:3 will affect speeds, as will channel size. If you want speed from 5GHz you need to use 80MHz channels. If you want coverage from 5GHz in rooms beyond the one the router or AP is in you should be using 40MHz, or even better 20MHz as you'll get better signal strength. Obviously when you drop down you sacrifice speed.

 

IMHO in the real world ~300Mbps over WiFi is a pretty good performing solution.

one would hope the NIC is off a PCI-E lane over thunderbolt. 

 

 

 

i would not be surprised if a USB to NIC chipset is used on a USB3 hub though..

 

That's not to say it can't push gbit, the ones @richms is refering to are ones that say usb3 but are essentially still a USB2 chipset running the actual network interface.

 

 

 

Often these still negotiate gbit.

True, but I'm not USB at all

Think we are getting slightly too technical here.

 

 

 

@astroboy I'd wait till the dock arrives, give it another shot over Ethernet.

 

Please use the mac app, as for 200mbit+ browsers can have significant overhead involved. https://www.speedtest.net/apps/mac

 

 

 

Without a doubt, at peak that plan will perform like every other gbit plan, flying colours.

 

The hg659b is more than capable of routing gbit, which is typically the most common failure point when someone buys a "AC GBIT ROUTER!" off the shelf at a electronics store

350mbps (about 45MB/s) is a pretty typical max speed for 2x2 AC, which is what the 2017 13" Macbook Pro (non-touchbar) has. The touchbar models have 3x3 and can theoretically do higher speeds, but this is heavily reliant on your router hardware and the wireless topography of your house.

 

Basically it's a complete waste of time to try and troubleshoot gigabit fibre speeds without a wired connection.

 

One could probably also make the case that it's a complete waste of time to even HAVE gigabit fibre speeds without a wired connection...
