How to effectively set up Wi-Fi network

So I need to set up a wifi network in a coffee shop. The deal is, if it’s open, everyone can connect since the coffee shop is placed below an apartment building and blow away bandwidth on child porn torrents or whatever. If I place a single password, customers quickly learn it and the word spreads around – in a couple of days we have trouble playing even internet radio. I know that there is a system where a randomly generated password which lasts for an hour or three or whatever is printed on the receipt customers get with their drinks – it lists the name of the coffee shop, address, phone numbers, work hours, what customers had, date, hour, VAT and total amount of money owed…you know, a generic strip of photo sensitive paper. How do I set this up? Any special software or hardware? Thanks w-bb community!
Answer #1
Number one don’t even think of doing this with rubbish consumer routers. Get a Cisco Aironet (Not Linksys!) off eBay even the 802.11n models are under 200 bucks now. Enable the firewall and only open the ports you need rtp HTTP imap exchange etc. And enable qos As for the authentication go with WPA enterprise with MAC authentication get them to make an account and password on a comp beside the till .
Advantage of this compared to the rubbish consumer solutions is you can use solarwinds or any SNMP tool to monitor any bandwidth hogs and revoke the associated accounts, simple.
Any old computer with server 2012 will do for the RADIUS server just install the nps role google for how to use nps with Cisco for wpa2 enterprise.

Your gonna need a dedicated server computer for this task. Doesn’t have to be anything
fancy tho. And your also gonna need either a DD-WRT supported router or a wireless access point+additional Ethernet card (depending on which method your gonna be using)
Method1 – Debian & DD-WRT along with Chillispot, Freeradius & MySQL
