Hi Miachel, i'm sorry to hear about the accident with your daughter. Hope all is well mate.
Yes, it's worth trying the builtin utility, nothing to do really, just let w7 detects them and you should be able to go online, so long as there are no secuity blockages from these hotspots. Pls have you w7 securitized with AV softwares. MSE and AVG are free and would be a minimum.
If you feel third party is the way to go, then by all means, use it. No harm in trying i suppose.
