Looks like CradlePoint reacted quickly with the issues that were still present in the 1.8.0 firmware. Our tech support department has been working with CradlePoint's and it looks like the 1.8.1 release may have everything working smoothly. We are comfortable in recommending this latest firmware. We would love to hear your comments, after upgrading, post your success or failure at:
