I’ll start this by stating I will try to provide as much relative information as possible. I have an interesting situation with my home network in which my old old wifi SSID is still showing up on found wifi signals. Not only is it still showing up, but using a wifi analyzer its also showing to use a massive amount of bandwidth on channels 1-5ish on the 2.5ghz Band.
A little backstory.
I purchased an asus wireless AC router back in 2014/2015ish in my old apt, and named its SSID. For the sake of discretion I will call its ssid as Asus01. Now I have since moved twice, switched from Spectrum to Fios (who by the way have gotten shittier over the year) and been utilizing their shitty ac router so my roommate can utilize the cable package. For the longest time my asus router was unplugged, never connected to the new home network and tucked in a box, until I let a friend borrow it. Even though it was disconnected and unused for about a year and 1 additional move, its SSID is still broadcasting. My initial thought that maybe it was being cached on another device that used it, such as my or my friends PCs, our cell phones, the ps3, smart tv, ect. Slowly I been eliminating each of those as a culprit. Since our most recent move (router still not hooked up or powered on) I have fully upgraded and replaced all parts of my pc save for my psu, my roommate and I both got new phones, the ps3 was disconnected and boxed, and until a week ago my roommate had his pc in storage unused.
I am really wracking my brain as to why my old router ssid is still showing up on a network scan, and where it can be coming from.
If anyone with more networking knowledge than myself has any ideas I would really appreciate any insight.
thanks fellow nerds.
