Windows 10: lan usb adapter typeC, which is identified as Realtek USB Gbe doesn't work

Hello all! I have a laptop Xiaomi notebook pro 15,6, i-7 Win11pro, a router Redmi AX6 and a lan usb adapter typeC, which is identified as Realtek USB Gbe Family Controller. When I connect my laptop to the router by wire, the system network eth works for a couple of minutes, then starts "flashing", i.e. constantly on/off identification. At one resource, I was told that the router has a voltage of 1.05 and 1.8V but the controller supports 3.3 volts. And therefore cannot work with this router ax6. Confirm this to me, please. Or give me your opinion about thisd issue. Took all known steps to

:)

 

Weird problem, Realtek USB 3.0 GbE adapter not working on one PC


I have a weird problem on my Windows 10 Home laptop since a few days my Realtek USB 3.0 GbE adapter isnt working anymore. It worked fine before and it is also still working fine on my desktop PC, a Windows 10 Pro.

It always shows "identifying network": https://i.imgur.com/nn7vHvU.png automatic and manual IP config dont work, both work fine on the desktop. It took me some time but I think the problem is a weird driver issue. Because on the laptop the device shows as:

Realtek USB FE Family Controller, which seems to be wrong. The correct naming should be, was, and is still on the desktop:

I looked onto the Realtek site and it seems there was a driver update a few weeks ago to: 10.5.1019 and it seems that Windows downloaded the driver a few days ago on my laptop and since then it got broken. The desktop has still the old driver 10.5.915.

I tried to deinstall the driver via device manager and also clicked remove the driver on my laptop and Windows installed version 10.5.915 again afterwards, but it stays broken, it stays with the weird naming "Realtek USB FE Family Controller" instead of "Realtek USB GbE Family Controller" like it is on the desktop.

I also noticed when I plug in the adapter, it is first named correctly "Realtek USB GbE Family Controller" in the device manager on my laptop but then deactivates again and activates as "Realtek USB FE Family Controller".

I also noticed the network settings totally differ on the desktop and the laptop:

Desktop (working) correct identified driver: https://i.imgur.com/EUDWsle.png

Laptop (not working) obviously not right identified/loaded driver: https://i.imgur.com/5PMkCCf.png

I guess FE stands for Fast Ethernet but the cable and switch port is GbE of course. And even if it was Fast Ethernet, that doesnt count for why it isnt working at all.

Link also shows working and as GbE on the laptop: https://i.imgur.com/kg1PZbi.png

 

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 pro and it is up to date.





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

One more thing when i setup the driver from CD included with the adapter its installed but the problem remain the same.

 

USB-LAN adapter not recognised

Please verify the model ln-030 v3 001 - I couldn't find v3 on Site.com
The ln-030 has a few HW revisions - please post a screen shot of the label

There are older drivers for the v1 HW, but no drivers for the v2 HW

Arc's suggestion to use Windows Update and Jimbo's suggestions to connect a cable to your USB LAN adapter and to your network + use a USB 2.0 port are good places to start.
