[ale] HELP, need to setup wireless access point!

[Ron Frazier]

I don't see what the problem is.  I go though two routers all the time, 
both doing NAT, to get to my internet connection.  The following should 
work fine with LAN cables between the parts.  Paul is welcome to call me 
personally if he needs help.

wifi router WAN port --> ADSL switch port
ADSL WAN port --> ADSL wall outlet

The PC's can connect either wired or wireless to the wifi router.

PC --> (wire) wifi router SWITCH port
PC --> (wireless) wifi router radio

Works like a charm.  Everything has DHCP turned on.

Wifi router should have:

Firewall - ON
NAT - ON
WPA2 encryption - ON with good long random password
    see https://www.grc.com/passwords.htm - you can store the password 
in a text file on the PC
DHCP service for LAN - ON
Auto obtain IP from ISP - ON

UPNP - OFF
remote admin - OFF
remote ping reply - OFF

Sincerely,

Ron

(PS - If you email me and don't get a quick response, you might want to
call on the phone.  I get about 300 emails per day from alternate energy
mailing lists and such.  I don't always see new messages very quickly.)
