Hi Yusuf,
In the logs you attached, there's appear to be a successful connection in both cases. If I'm not mistaken, the AP you used is AirTiesWir and the CC3000 is LSResearch:02:12:2C.
I don't think the problem is related to IRQ. I'm not even sure there's any connection issue with the AP, maybe only messages afterwards such as not getting DHCP.
Can you please try the following:
1. Test in Open (remove the security from the AP) and re-test
2. Test with a different AP. There may be an IOP problem with this specific AP
3. Please specify the exact model of this AP. I may try this here if we have the same model
Thanks,
Tomer
