Thank you for contacting NXP Support!

Unfortunately we don't know what the problem could be since is a Nordic Semiconductor chip.

I recommend contacting Nordic Semiconductor support or U-BLOX support to get the driver.

Also if the problem persists you can use one of our wifi solutions and are already integrated in our BSP.

Best Regards!
