How to identify Wi-Fi connected devices from a tablet

Good evening,

It's probably nonsense! The tablet's antivirus is not reliable. Is it the role of an antivirus to analyze wifi connections?

If you have any doubts, change the wifi password and make it something strong, at least fifteen characters long, with special characters.

Pipe dream? I never frequent forums or social networks, so I don't understand this language. But for additional information, here it is.

I have had the same antivirus for years on my 4 devices, which is Kaspersky, which has indeed reported the presence of this intruder on my network. But my provider, Bell, says there is no such activity on my network.

Although I don't really understand much, my first instinct was indeed to change the password of my wifi. But this connection still appears in the analysis that Kaspersky performs on my tablet, but not on my 3 other devices.

I really don't know how to remove it from my tablet, if it is indeed hidden in my network... Kaspersky has even identified the IP and MAC addresses of this intruder Quantenna!!! ???????????? By entering this MAC number into Google, I saw that many others were dealing with the same intruder, with no solutions to fix the problem, i.e. disconnect it.

Do you have another solution in mind?

One thing is certain:

If you have changed your Wifi password to something quite complicated and if your network is normally secured (WPA2), no one can connect to your wifi.

Moreover, I see that Quantenna is a company specializing in wifi. They notably provide mesh networks. Do you have a repeater from this brand at your home?

I really think your antivirus is mistaken and triggering a false alarm.

Hello.

Identify the IP and MAC addresses of this Quantenna intruder

Quantenna is a well-known brand that sells WiFi solutions found in some boxes and repeaters; this connection is likely coming from a device you own.

There's no need to be afraid of something normal, so stop freaking out for no reason.

I'm redirecting your post to the WiFi forum.

A hello, a reply, a thank you are always appreciated.

HELLO... bazfile...

I have no experience with forums, which I'm using for the first time, so thank you for your "indulgence" in the absence of the introductory "Hello"!...

However, even though I'm not a tech pro, I can still identify an intruder on my network (especially with the help of my antivirus that confirms it), as I know all my devices that are connected as well as the identity of my network.

Since I can also submit the MAC to a Chrome search, I have also discovered that it indeed is an intruder that several other people have reported (and not a "normal" thing) and they are unable to get rid of it, just like me.

As for "flipping out" for nothing, thanks for the advice, but I'm taking care of that aspect of my cautious personality.

Thank you for your help, even though the question remains.

Hello again Pierr10,

"WPA2", "repeater", it's all Chinese to me, a senior just doing her best!

All I can say (and what I can handle) is that I have a very simple setup, done by Bell, my provider, which indeed installed 2 devices in my home 4 years ago, namely a modem and a 4K recorder, neither of which are branded Quantenna, and I have 4 simple connected devices (3 computers and a tablet), each with a code to access them. Bell tells me they don't see this Quantenna connected to my network, while Kaspersky on my tablet continues to indicate it as being connected to my Bell network. And Kaspersky's alerts in the past have always been reliable and easy to resolve, except this time.

Anyway, it's exhausting me, I give up. Thank you.

Hello,

If it's an Android tablet, you can install the network analyser app.

And lan scan ...

And there you go ....

But goodness, those line spaces are so annoying!!

WPA2 is the protection mechanism for your wifi network (Wifi Protected Access). It is the most common and provides good protection. It is of course used by Bell:

If the WPA2 wifi key is complicated enough, it is practically impossible to connect to your network.
And Bell has confirmed that there is no intrusion.

Knowing that Quantenna is a company specialized in Wifi, I thought you might have a repeater (not a repetitor) from this brand: it is a device that replicates the Wifi signal, thus increasing the wifi coverage in a house.
bazfile had the same idea.

You know better than I do what is connected and how your network is set up. So my idea was not good.

For me, the problem is with your tablet.

1) I don’t understand why Kaspersky is interested in what is connected to your wifi network. That is not its role.

2) There is something else that stands out to me: you wrote

Since I am also able to submit the MAC to a Chrome search, I also discovered that it was indeed an intruder that several other people report (and not a "normal" thing) and cannot get rid of, like me.

You submitted the MAC address to a search. However, a MAC address is unique and specific to a device. Your search should not have yielded anything, unless all the people who reported it received the same message, probably a fake.

I doubt that Kaspersky is behind the alert.

I already advise you to clear the cache of Chrome.
Settings => Applications => Chrome => Storage

There is normally no virus.
