bt voyager 1050

hi

i got a wireless bt voyager 1050 adapter to connect to the router at work
and it works great.

when i installed it it found the router and i added to the left table on the
adapter setup.

trouble is at work they turn off the router each day. (just what they do
nothing i can do about that(

the next day the computer comes on find the router and cant connect to email
or internet
unless i remove the router on the left list and re-add it right to left on
the table.
then it works.

is this because they turn it off and its maybe gets a new ip or something?
any way so that i dont have to remove and re-add router to use it?

hope that makes sense

thanks.
