WRT610N - connected to multiple networks?

Question

Hi all, I bought and set up one of these routers yesterday and initially my laptop reported it was connected to multiple networks, same SSID but different antennae, it meant I could switch between 2.4 and 5.0 GHz without dropping connection and obviously had great connection strength.  But after a shut down and restart it will now only connect to one antenna at a time.  Which is the correct way for the connection to work, should it be connected to only one antenna at a time?
Thanks in advance.

I've obviously not been clear, when I set up the router yesterday I set different SSIDs for the two bands, LINKSYS1 for 5GHz and LINKSYS2 for 2.4GHz.  When I connected to LINKSYS1 I got 2 connections simultaneously, one labelled "LINKSYS1" and another lablled "LINKSYS1   2" both providing a 5GHz connection.  I also had another connection at one point called "LINKSYS1   3".  Exact same thing happened when I connected to the 2.4GHz band "LINKSYS2" (i.e. I had 2 connections labelled "LINKSYS2" and "LINKSYS2   2" both providing a 2.4GHz connection).  Hovering over the network icon showed 2 connections and network and sharing center showed connected to multiple networks.  When I restarted it this morning it's only connecting to one and the converage isn't as good (could get 100% signal from outside last night and stream DVD iso's but it's buffering quite a bit today).  I've googled it and some other people have mentioned the same thing but they seemed to think it was a fault, but it gave me better coverage than I'm getting today.  What I was asking was which is the correct way for it to operate, as one connection or multiple connections.
