A second one.

I cheated and left out some details.  Like assuming that the allocated wds cid was 1. If your modem has made 
other allocations earlier, for example a previous connection attempt, then this won't hold. And you get 
results like yours.

You could continue guessing until gou hit the correct cid, or you could do it properly: allocate a wds cid 
manually, connect using this cid, then check the settings using the same cid.

For ipv4v6 you'll probably want to do this it this way since you have to juggle two cids.
