Cutting pcb lines and soldering on your own component? That will be hard if
not impossible to make work; the antenna is actually part of the pcb (it
still has connecting lines, of course).

No, there's a resistor (probably 0ohm) that connects it and you can
move it to instead connect with a footprint left for an antenna
connector:

    60MBps is the maximum signal bit rate, yes... But that ignores overhead
in USB control signaling (turn around between polling the bus to find
devices with data to transfer, requesting the transfer, length of packet
transferred -- shorter packets will involve more overhead -- ack/nak of
packet, encode/decode time [checksum or CRC, and USB3 at least uses an
encoding that takes 10bits per byte, to ensure state changes occur often
enough to keep the sender/receiver in sync -- no runs of eight 0 bits, for
example]...).

    The effective max is around 30MBps -- and that probably assumes a
single client per host controller. With more than one device on the bus,
the host will have to poll each device, then determine which gets to
transfer data.

Clock speed is pretty immaterial, it is a dedicated router chipset, with  
gigabit Ethernet, a/b/c/g/n/ac WiFi, and is vastly better as a router  
than a general purpose Pi Zero W with everything going over a single USB  
bus.

Well you wont find anything better at doing WiFi routing than a WiFi router.

yep and the 68u is an older model.

the more recent 86u includes hardware encryption, giving a huge boost
to vpn performance.

yep.

Don't try to make sense of the Asus model numbering.

RT-AC66U/R/W  
    <https://wikidevi.com/wiki/ASUS_RT-AC66U
    Broadcom BCM4706 (600 MHz, 1 core)

RT-AC66U B1  
    <https://wikidevi.com/wiki/ASUS_RT-AC66U_B1
    Broadcom BCM4708C0 (1 GHz, 2 cores)

RT-AC68U
    <https://wikidevi.com/wiki/ASUS_RT-AC68U
    Broadcom BCM4708A0 (800 MHz, 2 cores)

RT-AC68U Extreme
    <https://wikidevi.com/wiki/ASUS_RT-AC68U_Extreme
    Broadcom BCM4906 (1.8 GHz, 2 cores)
    VPN Acceleration using hardware encryption

RT-AC86U  
    <https://wikidevi.com/wiki/ASUS_RT-AC86U
    Broadcom BCM4906 (1.8 GHz, 2 cores)  
    VPN Acceleration using hardware encryption

My favorite ASUS firmware mutation:

OK, but it's range rather than bandwidth that was my real concern.

I'll admit that I've been lazy and haven't compared the FCC data for
USB WiFi adapters yet. But I've seen that there are some designed for
longer range, so I'm hopeful that there will be something equivalent
to the transmission power of my existing router, if the Pi ZeroW's
onboard WiFi doesn't prove powerful/reliable enough.
