A couple of days back, I got a couple of sms alerts saying that a new device is now connected to your network. The names of the devices were MAC 34 and MAC 35 and their MAC addresses were likely locally administered MAC addresses or randomised MAC addresses, one started with C2 and the other with 36, and I was not able to trace it to any vendor. When I checked my jio app, I saw another device named MAC 30 and I ended up blocking all three devices. Later, I realised that MAC 30 is my Jio STB and unblocked it. I called Jio helpline but they just told me to block and change my password which I had already done. Could this be someone who successfully hacked into my network or just stray connection attempts or something else?

Even I'm having a similar issue with my jio router, for me MAC 1 & MAC 4 were always connected to my device. I tried blocking it, putting a strong password, renaming SSID, disabling visibility and resetting the device numerous times but nothing works it's still connected when I tried reaching customer care support even they were unaware of this problem. I guess its a factory error hope they will rectify in the future when they receive multiple complaints.

Thanks @ap99 I now understand what Random Mac address means.
I have 2 devices on latest iOS and I do understand now why they show twice on MyJio, this was due to me connecting to 2.4Ghz & 5Ghz SSIDs. This means they were properly broadcasting their device name and got added and I was alerted with proper names. This Random Mac id uniquely ties with the SSID. It was really helpful.
Good reference: Use private Wi-Fi addresses in iOS 14, iPadOS 14, and watchOS 7
I have no other device on android 10 (or Q) or iOS 14, so basically I have no other latest device with Random Mac ID feature. I believe even if I had then also it would have reported proper resource name to the router as mine devices did. It won't have been Mac 10 or Mac 16 na?
Maybe you are correct, just that I'm very doubtful.
Thanks again for the info.

@flame10 I am using a Redmi 4 mobile which shows up in the MyJio app as 'MAC3'. Don't know why that happens but yes some devices show up as 'MAC3', MAC4', etc. while some devices are visible with their proper names. (You can change this name in the MyJio app from 'MAC3' to something which you can easily identify like 'Redmi4' or something.)
If you want to make sure that the devices which are connected to your router are really yours, just login to the router settings.
Go to Security->Firewall->Client Access Control (rightmost option). There you will see the MAC addresses of all connected devices. You can tally those with your devices if they are the same or not.
PS: Just so that you know, the installation guys who install the router, connect to your wifi to set it up for the first time. So naturally their device names get added in the MyJio app as well. Only way to remove those from the list is to reset your router.

on my RelianceJioFiber i have also noticed much of similar IDs popping in randomly, which i was suspecting to be handiwork of customer support team;reason for me to think so is in last 3 days, i have made 15 calls to cstspp to get my RMN recognized by the App,Router to be a valid working device
I got a cople of support guys in two of those calls to tell me names of devices they can see on my router
implies they have at least view access
if some support guys have view access, what prevents others from having deeper access?
on my own investigation, for reason for this RMN block, noticed on ClientAccessControl today that this device was in 'deny' mode, not 'blocked' mode
what one blocks, one can unblock
what gets denied by 'central control' one can't unblock at app level
question is how did the RMN MAC address get in 'deny' list along with about 14 other random device IDs
that earlier were generated and lying in the 'block' mode
i noticed that after an MyJio App upgrade 4 days back this change happened
so there was some piece of code written in upgraded App that has created this deny list
based on some algo pushed many IDs into this list along with the RMN MAC
now CstSpp is not interested to answer this query
they have asked me to change my phone if unblock didnt work
will hard reset remove this issue that the 'deny' list gets cleared? - i don't know, neither would cstspp
how do i resolve?
