Lightbulb That Blue Linksys Router -- Mysterious Light and Button


I just noticed that on the linksys routers, in the front there is a button with a light in it. I never, ever, saw it, until today. I was curious and just pushed the logo of "Cisco Systems" on the front left of the router. It started flashing blue!! I pushed it again, and it turned orange / yellow. I noticed it after i updated the firmware...

I am totally confuesed: What does the color of the light have to say?? Is it important?? Is my router just weired or does your linksys (i have a WRT54G v.3) do the same thing??

I couldn't find anything in the manual or with

Try pushing that "cisco systems" logo-button and see what it does. Let me know if you have any idea...


PS: I hope this question isn't all as stupid as it sound ;-)

It could be a button that selects either 802.11b (amber) or 802.11G (blue). Call Linksys about the problem.

Logo (on the left) but no button on this WRT54G

Did it just appear after the firmware upgrade? Which version do I need to get the button?

I upgraded to version 4.2.something.

The button is a mechanical button hidden as a logo. After i upgraded (and maybe touched this button, while doing a reset??), the button lit up.

I still have no idea what it does.

I have a WRT54GL v1.1 and I was wondering that same thing. The Cisco Systems logo usually glows orange when the router is running. I tried pushing it several times and it started blinking white, like on and off. Like a strobe light. It isn't to change 802.11x connection, that is through the Web UI. Seeing what PC Mag said at that link, there is an icon in the UI that does the same thing. Interesting to know.
