By the time that Earthlink realized that its ambitious plans to build out citywide wireless networks weren’t going to happen without a whole lot of money, they already had five standing networks that they needed to deal with. They said at the time that they would be seeking to give those networks back to the city or sell them off. This week they completed the return of two networks – in Corpus Christi, TX and Milpitas, CA. They remain in negotiations with Philadelphia, New Orleans and Anaheim to determine the terms of releasing or selling those networks.
