Another option is to have "fake" tabs. Just have 1 tab for the current network, then use buttons for moving "right" or "left" a "tab". When pressed, they just load the tab information for the next network into the same tab. It will appear as though it's a new tab, but will always use one tab. If you want to get more creative, you can have 3 network tabs where the middle tab is always the active tab and the left and right tabs show the previous and next network names, but cannot be activated (clicking them and/or clicking buttons will change the active tab's contents to the new network).
Depending what you're doing, this can be a very useful method and is relatively easy to set up. Then, if you wanted to, you could just have a "main" tab that lists all networks and let users click a network from the list and it would bring that network up in the active tab so you don't have to go through all of the networks one by one to get to the one that you want.
