If that doesn't work, to to UDP 2000 - 3000.
BTW, if you only get the "Switching to TCP" sometimes, it is general a problem with your connection quality. If the UDP connection gets flaky, AH will try to switch to TCP for a more reliable (though slower) connection. If this is happening I suggest you try the alternate route. You can do this by selecting "Alt route verio" from the arena selection menu. This will still take you to the main arena, but it will do so by the alternate IP route. It may improve your connection.

A pig is a pal, who'll boost your morale, Though mountains may topple and tilt.
When they've blackballed, bamboozled, and burned you, When they've turned on you, Tory and Whig,
Though you may be thrown over by Tabby and Rover, You'll never go wrong with a pig, a pig,
You'll never go wrong with a pig!" -- Thomas Pynchon, "Gravity's Rainbow"
