View Full Version : Linksys WRT54G password security

Hi all,

I don't know much about wireless security. I have a friend who uses a
Linksys WRT54G router connected to his cable modem so that an OS X
machine in a different room connect to the web using airport. I have
noticed that the airport in OS X can see several connections (presumably
from neighbors), including the Linksys one. But while all other
connections are password protected, the connection to the Linksys is
not, and this troubles me.

On the comuter that is physically connected to the router, I have httpd
to 192.168.1.1 and I've noticed that there is a place to set the
password, however changing the password would not deny connections to
the OS X machine. The machine sees the Linksys router and doesn't even
ask for password. it gets connected right away. So I am guessing that
the password is an administrative password, and not for connections.

Does the WRT54G model have a capability to be password protected? The
firmware has never been updated, how essential is that for password
capability or for security in general (How does one update the firmware
anyway?) Since this a relatively old router, should a more up-to-date
one be purchased? If not, what is the best way to secure a connection
with this router?

Thanks very much,
RS

I'm not familiar with that router but you need to go into the wireless
section. In there, there is the option to input the SSID (network name -
call it something unique so that if there is more than one Linksys in your
area, you can be sure you are connecting to your own and not a neighbour's),
choose WPA-PSK encryption (or even WPA2 if you can) and when it asks for a
network key or passphrase or password, go to
https://www.grc.com/passwords.htm and get a 63-character password.

Any computer that you want to connect wirelessly to your Linksys will have
to have all this information in the utility software used by your wireless
adapter - whatever you put in the router must be matched at the client end.

The WRT54G with stock firmware is capable of WPA at least. I'm sure OS X is
as well.
