NetworkJS and http modules not found

Wow, I never heard of that before, but what @DrAzzy says sound right (although it should still work at 9600 baud - albeit a bit slowly).

You could try running wifi.at.debug() to see what the module is sending back - it's possible it is working, but that after it boots it doesn't send the text ready. - for some reason they keep changing what it prints every so often!
