Windows 10: REALTEK USB Wireless LAN Adapter setup failed.

I have been trying to setup a wireless USB adapter from 2 days but i'm failed. It's a "USB 2.0 Wireless 802.11N" Lan Adapter. When i connect it to computer it's driver showing up to the device manager for a few seconds and then vanish. Sometime the driver stay up a long time but i can't configure Wifi. When i connected it, in device manager under network adapter it shows "Realtek RTL8188FTV Wireless LAN 802.11n USB 2.0 Network Adapter" some time it comes up with a yellow sign. I'm tried to setting it. My computer windows version is 10 and it is up to date.



it's a picture of 300 Mbps but mine is 600 Mbps.

Wired LAN connection and USB wireless connection?

Would connecting my desktop using the usual 10/100 LAN cable and a USB wireless N adapter yield better internet speeds?

 

No LAN Adapter | LAN Miniport missing from adapters

I've just bought a Acer Aspire E5-575G (not the best choice for gaming, but on a budget). I've been happily using it for playing games and browsing the net, but I turned it on again a month after having it to see the "Network Connections" icon turn from LAN to Wireless.

The last connection I had plugged into it was a LAN cable which worked perfectly fine and dandy. I went to "Change network adapter settings" thinking I could change it back to my wired internet to find there was no Ethernet adapter, but just the Atheros Wireless adapter (in this laptop, it's only 72MB/s)

I then restarted my laptop thinking the adapter hasn't started correctly. When I restarted, the "Network Connections" icons briefly flashed the LAN icon with the "No connections X" over it then changed to wireless. Still, no Ethernet adapter was available to select. I then went to Device manager and saw that there was no LAN drivers installed, just Atheros and the standard WAN IP and WAN IPv6 drivers.
I then perused the Acer Driver site and found the only available LAN driver for my model of laptop, Realtek. I downloaded a fresh copy of this driver and installed it and got, from what I've looked up, the "Deep sleep" error. I configured my power settings to never sleep or turn off when plugged in, restarted and tried again and got the same error. To add to this, when the LAN driver was working, I never remember it saying "Realtek" anything, but I could be wrong.
