Aruba

I need to backup a switch specifically the image, I was using the following command for other models of cisco copy flash tftp 192.168.x.x BK-CN80HLR-12052022.swi This same command in the 3com 4200 switch does not work, I would like to know with which command I can do the same in this switch...

Hi, I'm planning to upgrade my WiFi network. Now, I wonder whether to buy "MikroTik cAp XL ac" or "Aruba AP-205". The price is more or less the same in my country. Which one is better for the apartment? 1,2 - room; 3 - kitchen; 4 - bathroom; 5 - hall; (1 room is divided by a wall unit)

The system doesn't even see the card at all, device manager doesn't find anything but when I replace it with an HD 5450 everything works fine. The card is not dead cause I tested it on other system and it works fine. I'm really curious on what could be the problem.
