WIP_BEV_CONN_FAILED and its consequences

Hi,

Sometimes I get a WIP_BEV_CONN_FAILED when I try to connect to the Internet. What is the correct procedure to go on from that?
I used to issue a wip_bearerClose() but it sometimes lead to the following problem:

Should I rather use a wip_bearerStop() instead? The WIP documentation is not very explicit about that. According to the state diagram it is not necessary, but who knows…

Thank you for your help!
