CC3300 hangs on REQUEST DHCP

Post by kochrd »

I installed Adafruit CC3000 WiFi Shield with uFL Connector for Ext Antenna on an arduino.
Then checked operation with the BUILDTEST script from the Adafruit LEARN site.

I was able to connect to the local network, but when the script reached REQUEST DHCP, it was unable to proceed.

I'm a network newbie, so any insights would be appreciated.

What output do you get in the Serial Monitor when you run the buildtest sketch?

Let's take a look at the hardware too. Please post a photo of your shield, ideally with enough detail that we can check out the solder joints and make sure there none of the components squirmed out of place in the reflow oven.

Did you solder the headers on to the shield before testing? can't really tell from that photo.

Yes, headers soldered on prior to testing.
Solder joints checked out OK with DMM and microscope

We have had a lot of problems from people trying to power the arduino and shield from a laptop or through a non powered hub Try using a power supply or a powered USB hub.
