Can't get the iUSBport/iUSBport2 join to the known network. Please check the following:
1.) Make sure the router's password is keyed in correctly and password does not contain special characters, such as @#$%^*
2.) Check the Mac Filtering in router is not on. If it is, please turn it off to add the iUSBport in and then enable the feature again.
3.) Change the security setting in router to WPA first. Once the iUSBport/iUSBport2 is joined to the known network successfully, please change the security back to original setting.
