Brute-force on my WIFI

[Alecs]

Hello, in the last days I have checked my router for events and it looks that someone is brute-forcing my wifi. I know that I can't do anything but this will affect my router (in the sense of spikes,lag, etc)? In the last few weeks the internet it's working a little bad I have a lot of spikes when I'm playing online games with my friends. Find bellow my log that is non-stop with 2-3 tries per second. I have set my wifi to accept only what MAC addresses I allow. It is only this MAC for the moment.

12/25/2020 21:28:12 STA not included in Accept Address List : <WG-MAC=4c:12:65:***>;<STA-MAC=cc:af:78:00:00:00>;<IF=wlan0_0> Wi-Fi

Thanks,

Alex

Could it be your mobile phone or tablet? The OUI (first 3 bytes of the MAC - identifying the manufacturer of the [wireless] network chip) is registered to FoxConn - typically producing WLAN chipsets for mobile equipment.

My devices are registered with MAC address to be able to connect to wifi. 100% is not my device, I checked and I don't have any device with this MAC.  For sure some neighbour it's trying something 😄

Hello Alecs,

Normally, this should not have any serious effects. Nevertheless, we will be happy to take a look at your connection.

Hello Alecs,

the modem data in the upstream are not ok.

A technician should take a look at this on site. Would that be okay and will the colleague come with you to the house installation? The cause seems to be in our area of responsibility. In this case, the service is free of charge for you. If the technician does not meet anyone at the agreed time and cannot gain access, we will charge 99.50 € for the service.  

Under which phone number can the colleague make an appointment with you?

Due to the current developments we have to take certain precautions. Therefore we need to know if there are any symptoms in your household that could be related to Covid-19. Of course we don't want to offend you, but on the other hand we don't want to endanger more people unnecessarily.

Greetings Moni

Hello Moni,

Thank you for checking this problem. There is no Covid19 infection as we tested this Monday and the result was negative. I will send you via PN my phone number to make the appointment. Me and my wife will be at home as we are working from home, thank you again!

Hi Moni,

I have access to the basement and to this 3 "metal boxes". (looks like I can attach only 1 picture, there is one more box with a label from another internet company).

I don't have access to the elektroraum. Probably if I contact the owner I can receive the keys but only if it's needed.

Hello Alecs,

please contact me when you have asked the property management. Then we will assign the technician.

Greetings Moni
