There are four wifi units set up to cover the selling area. Please go to your wifi settings and select the strongest of the four. They are losfelizflea1, losfelizflea2, losfelizflea3 and losfelizflea4.
The password is: losfelizflea and it works for all four. You may have to join each network as you are in different areas of the flea market, but once you do it once, the strongest one should automatically connect each time.
ATT and T-Mobile are the only two carriers that have coverage at the Flea Market.
