Thanks everyone for the tips. I'll go to Orient Village tomorrow morning and check what's available there.
@ Wendell, no problem with security with customers.
I only need good wi-fi performance for 1hr for a GoToMeeting conference call, during which I will share my desktop to show a couple of Powerpoint slides and discuss what they describe, that's all. No possible access to sensitive data from outside, my firewall blocks unauthorized access.
