Switch ips on a wireless connection?

HeY I often use neighborhood wi fi's and wondering if there is a way to force an Ip change?

Thanks

 

Depends on if it's dsl or cable.
If it's cable, login to router and disconnect and connect.
Cable is a bit more complicated .

 

its a wireless connection via microwave antenna. not dsl or cable.

 

not offered in the rural area I live in, and the one available does not offer enough bandwidth for the fee that they charge.
