I'm glad it is working for you. Since my anecdotal evidence conflicts
with yours, I would advise anyone to try both and see which works better
in a given situation. Certainly neither dhcpcd nor dhclient are
foolproof.

This is only hypothesis, but dhcpcd seems _to_me_ to be slightly more
sensitive to timings, and wireless interfaces tend to have slightly
slower responses when it comes to setting up and tearing down a
connection. The reason I suspect this is because when I have used dhcpcd
with a wireless interface, the timeout that I set seemed to make a
difference to the success rate when it came to gettig an IP address. But
that is strictly my impression coloured by my own experience, and I offer
it as such.

YMMV, no warranty express or implied, errors & omissions excepted, &c.
