EXPLANATION
The SSID (Service Set IDentifier) is the name of a wireless network.
The SSID (Service Set IDentifier) is the name of a wireless network.
If a router can create more than one network, then each can have its
own name/SSID. Whether each should have its own name is a debatable issue, but not a security one.
You should change the default SSID(s), for a couple reasons, one technical one not.
Using a default or common SSID, can make it easier for bad guys
to crack the WPA2 encryption. The network name is part of the encryption
algorithm, and password cracking dictionaries (rainbow tables) include
common SSIDs. Thus, a popular SSID makes the hacker’s job easier.
On a totally different level, you don't appear to be technically clueless.
Anyone who has not changed the default network name is immediately
pegged as a non-techie whose defenses are likely to be poor. There might
as well be a "hack me" sign on the network.
I have seen others argue that changing an SSID that has the vendor
name in it is good for security, as it hides the company that made your
router. It does not. The identity of the hardware vendor is advertised
for the world to see in the MAC address that the router broadcasts. Even
if you change a default SSID of "Linksys" to "Netgear", anyone with a
Wi-Fi survey app such as WiFi Analyzer on Android can tell that the
router was made by Linksys.
