I have a 2 story house with a Cisco E3000 in one corner of the basement.  I realize it is a lousy place to put it, but it is where the cable comes in the house.  It covers the house reasonably well, but when I tried to put wifi cameras on the outside opposite side of the house, they don't get enough signal.

I got a Coredy E300 to use as a wired access point.  I put it upstairs, about 2/3rds of the house away from the Cisco. Now I have a strong signal everywhere.  Success!

 

Well, almost.  I downloaded a program called Insidder Office that shows the strength and channel of all the signals it sees.  A screenprint is attached.  Toller is the Cisco, Toller_ext is the Coredy.  All the stuff below the dotted line are signals from my neighbors.  I don't know what the two signals above and below Toller are.  When I change Toller's channel, they also move; so I presume they have to do with me rather than my neighbors.

 

Originally I had signals from two wireless printers; they moved when I moved Toller.  I disconnected them.I have a firestick, a smart TV and a roku; unplugging them didn't change anything.  Nor did turning off my cell phones. There isn't anything else in the house that is wireless.  Well, the house phones are, but I unplugged them also.

 

So, a bunch of questions:

1) What are these two weird signals?  Do they matter?

2) The Toller_ext is 40mhz wide.  I don't see how to change it to 20mhz.  Does it matter?  

3) I turned off the Guest signal on the Cisco because I rarely use it.  Does it matter whether it is on or off?

4) Does leaving the printer signals on matter?

 

When I say "matter" I mean affect signal strength or cause interference.

Thanks

1. All MACs starting with 74-C2-46 are registered by Amazon Technologies Inc so that may give a clue as to where to look / what to turn off.  Perhaps a Fire tablet?  Unless totally shutdown they may keep the WiFi on.

Since they're following your Toller perhaps they are probably connected to the router.  You might open an elevated Command Prompt and type:

 

arp -a

 

That may give you an idea of what devices are still around.  You can also log on to the Netgear and check its ARP/MAC table.

 

2. Probably not important

 

3. Off is fine.  The guest is just to let you let other people use your network to get to the Internet without giving them access to the devices on your network.

 

4.  Printer shouldn't be a problem but if you don't need it you can turn it off just to clear the airwaves.

Those two signals have disappeared.  I didn't change anything; they just aren't there.

 

The only Amazon device in the house is a firestick.  Unplugging it didn't make the signals disappear yesterday, and using it didn't make them reappear today.

Could a signal that strong be from a neighbor, a minimum of 100' away?? I know one neighbor has several wifi cameras on his house; maybe they are Amazon.

 

Why did you say Netgear?  I ask because I got an email a few weeks ago recommending update my Netgear router; since my router is Cisco, I figured it was for something I owned years ago.  Is the E3000 actually Netgear??

 

Appreciate your help.

Reference to Netgear was a mistake on my part.  I guess I was thinking of Netgear because the A0:63:91 ... under the Toller waveform is Netgear.

Cisco bought up Linksys.  AFAIK they do not own Netgear.

 

Not sure where the Amazon things were coming from.  Check with your E3000.  If they are trying to use it you should see them in the MAC/ARP table or perhaps its log.  Also make sure you are using a strong encryption like WPA2 so your neighbors can't log in.
