Flooding Laptop MAC

alok_shukla_2wx — Sun, 12 Aug 2018 05:10:40 GMT

when a specific laptop is turned on all other wireless devices lose their connection but when that laptop is connected to the switch with an ethernet cable the connections are all stable.
typically when the laptop is connected via wireless we (7 other laptops and iPhones, occasionally more devices) all have connections dropped every minute or more.

I have tried updating the drivers on that laptop but they are already up to date, I have tried so many things that have been suggested but nothing seems to be working other than keeping it plugged into the switch constantly which is not an option for us.

the laptop also shows 100% disk usage directly on start-up when nothing else is running. sometimes stopping superfetch and windows search will search will help but not for long and sometimes not at all

I am hoping someone has an idea of what to do here.

What’s the encryption? Do you happen to be using TKIP or mixed-mode? If so, switch to AES. It’s a long shot but the problem laptop might be infected with something that’s triggering Michael countermeasures.

Encryption is WPA-2, we changed other encryption also but problem same persist again.
Please do suggest me on controller level how do we block that MAC on broadcsting.

Why not just remove the network from the laptop? If you don’t have access to the laptop I suppose you could add it to the blocked clients list.

The Apple MacBook which I use has some internal issues with its system, the laptop often gets a loose connection when it is connected to any wifi. This results in the loss of data which are not saved. Apple Devices Data Recovery allows me to recover the lost data and thus I continue to work on the data in spite of the bad connection of the wifi with my laptop.
