I had the same problem, but it seems it had to do with LTE. On my Fido (Rogers 
Canada jfltecan build) phone, WiFi tethering works fine if I switch to "Use 
only 2G network".

Others have reported how to use tethering with LTE here (I haven't tested):

I had full tethering support with my Galaxy S2 Skyrocket[Full LTE/4G/3G/2G, all 
modes] after a update or two of android-wifi-tether, any combination of 
toggling LTE/4G/3G/2G options doesn't change the outcome on my Galaxy S4.

Starting hostapd... FAILED

I can confirm I also don't see any wifi networks popping up to work with, I'd 
assume the directions on performing commands using iptables wouldn't work for 
me since there wouldn't be a functioning wifi network to reroute traffic from 
anyhow. And the link about the user failing to get internet access and them 
troubleshooting APN settings is also a different issue. Thank you for the 
suggestions, but they seem to be addressing a very different issue.

Both of those links appear to be complaining about their hosted wifi network 
not leading anywhere, the issue I list is about how the wifi network is never 
created, as confirmed by the fact the software is failing to either set the 
wifi driver to ad-hoc, or failing to launch the hostapd to perform in 
infrastructure mode.

I'm guessing the issue is closer tied either to an incompatibility with the 
CM10.1 and CM10.2 nightly ROMs(as I've updated since this post hoping that 
could fix the issue). Or perhaps a driver or two missing from the 
android-wifi-tether app.
