I have here an Asus Vivobook K570U model which I purchased about 3 months ago. This is actually the second laptop of the same model that I purchased; I refunded the first because the network adapter was faulty and didn't work upon purchase. I was beginning to think that this second one was gonna last awhile until the network failed as well last week, and by that I mean it says "connections available" on the bottom right, with a monitor icon and a red "X" on it. When that happens, I try restarting my computer, resetting the adapter, reinstalling a the driver, and even once resetting the entire device, but it usually doesn't work. The weird thing is I would leave the laptop alone for awhile and then the network would randomly start working again... then fail again sometimes later (this has happened twice since it first broke down).

The name of my network adapter is "Realtek 8822BE Wireless LAN 802.11ac PCI-E NIC", along with some "Realtek PCIe GBE Family Controller" (I'm just stating what I see under the Network adapters section in device manager).
I found that whenever the network fails, the "Realtek 8822BE Wireless LAN 802.11ac PCI-E NIC" would disappear from device managers, but reappear when the network starts working again. I would to ask what might be causing this, if it's hardware related or software related. When I try to troubleshoot, it says some cable is not plugged in or might be broken which implies perhaps there being a problem with the hardware, but such wouldn't make sense because if the physical part was damaged, it would remain down and not randomly start back up again.

Please help!

Faulty drivers for the laptop onboard card.... I would a return the thing. Or b if unrefunable at this point order a "HIGHLY recommended" one compatible with your laptop "that you control" the drivers to

That’s what I feared. Good thing it’s still under warranty so I can get the part replaced. Anyway, thanks!
