Hi  @Solla-topee 

Thanks for your response.

I first tried with the Device manager. Right clicked TP-Link adapter, chose Properties, then Power Management, unchecked "Allow the computer to turn off this device to save power", then OK.

Did a restart, but it didn't connect automatically.

Then tried with regedit:

Went to regedit and navigated to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\"

Then right clicked TP-Link adapter from Device manager, went to Properties -> Details, selected Driver key on dropdown. It showed "{4D36E972-E325-11CE-BFC1-08002bE10318}\0023". So chosen to enter 0023 folder on regedit. There double clicked "PNPCapabilities". It showed "18" as value. Changed it to "24", clicked OK, then File -> Exit.

Did a restart. Same result.

I have Enabled Wake on LAN from BIOS and it's set on Battery and AC. Still not connecting after reboot.

I tried to follow the instructions as much as I could. Please let me know if I did anything wrong or if I can try anything else.

Thanks.

Thank you for helping me in this.

In the meanwhile I visited offices of TP-Link importers in my country. They tried a new unit of UE200 on the same machine and the issue was still there. Strangely enough UE200 works on other Windows 7 devices after restart. The issue happens only on my device. But strangely, usb Ethernet adapters from other brands are working without issues on my laptop. I own a "Gigabit" brand USB3.0 10/100/1000M USB Ethernet adapter which has a similar chipset (probably RTL8153 / RTL8153B) and it works on restart on this machine.

After restart, Device manager does not show any TP-Link item under networking.

After I physically remove and reattach it to USB port it shows up.

> What is the error message on the Wifi network after PC reboot?

Sorry I don't understand what Wifi message you are referring to. The device is USB to RJ45. And to my knowledge there aren't any messages. It is just not being detected and the icon on system tray is showing a red cross upon restart. I have built in wifi and lan disabled from device manager so that they don't interfere with testing (as far as I remember it was also suggested by a TP-Link FAQ).

> To look into that fuether, please  share a photo of the Windows OS and motherboard information as guide here & And share a photo of the driver date, thank you
> It is also check recommended checking the Motherboard board specification and see if there are any settings that could affect the USB port.

The laptop is ThinkPad x201i with i3 CPU. Driver file name was "Install_USB_Win7_7061.20_12232021.zip" and I was pointed to it via TP-Link's official website.

Didn't get any progress on Windows 7.

Forgot to mention, on a Arch Linux x86_64 install, I tried:

1. without driver first,
2. then tried "r8152-dkms" from AUR,
3. then uninstalled "r8152-dkms" and installed driver (r8152-2.16.1.tar.bz2) like this:

$ sudo pacman -S linux-headers usb_modeswitch
$ tar -xvf r8152-2.16.1.tar.bz2
$ cd 'r8152-2.16.1'
$ sudo make all
$ sudo make install_rules
$ sudo depmod -a
$ sudo mkinitcpio -p linux
$ sudo reboot

I can't seem to post output here. Anything with / in it and it says "Content or title contains illegal external links." for some reason. If anyone is interested, output is available here: https :// bin.0xfc (dot) de (slash) ? f8f7dcf897189f83 # EVxpL1zG6r5kMaeFoLAGrxhYWPVqq3bdokyq2bF5Vvk4

Not sure about the SSL errors on "sudo make all". There is nothing about this on the ReadMe.txt file. If this is important, please let me know if the error can be avoided.

Result is still the same. No automatic connection on reboot while it is connected to USB. Have to disconnect from USB port physically and reconnect to get connected.

> the Linux error may not help with issue met on Win7

I know, but I use Linux too. When buying the UE200 I checked for Linux support and the packaging said it supports it. So presented my efforts here. Sadly the issue is present both on Linux and Windows.

It probably suggests that the issue is not with Windows drivers or any drivers at all. Since the machine connected and re-connected at least 2 other USB Ethernet adapters, without drivers and BIOS settings changes after restart, I think the machine is capable of connecting and being connected on restart automatically. Personnel from importers office have tested these other devices themselves too and confirmed that those work on restart. Not sure why only UE200 causes this issue.

Sorry, I can't see the email. I have sent you an alternate email on a private message. If you can check, that'd be helpful.
