Hi Rany.
Thank you for effort to help. Before that, two off-topics:
1. to keep the question tidy, could you please delete your previous comments which are no longer relevant?
2. Please how exactly did you create the chat room? I was never able to figure out a way how to do it.

rany

@miroxlav sure

@miroxlav done :)

@miroxlav could you access the page from any other device?

miroxlav

probably not now

but I can reconnect as soon as possible

my question is, how to find out which device is occupying 192.168.0.34 which throws a general failure (see screenshots) even if the PC is disconnected from network

rany

@miroxlav could you run the IP against nmap?

@miroxlav nmap.org/download.html

miroxlav

4:31 PM

is there a potrable version available? I'd prefer it but I can't see it...

rany

@miroxlav I'll check

@miroxlav nmap.org/dist/nmap-7.12-win32.zip

@miroxlav the link I just sent contains the command-line version of the program

miroxlav

oh. cool. downloading...

rany

@miroxlav Note: you'll have to install winpcap.org and microsoft.com/download/details.aspx?id=40784

@miroxlav but I advise you to install nmap since it is way simpler (GUI etc.)

miroxlav

command line is perfectly ok, if you have specific command at mind

if not, then I'll reach for the GUI

rany

@miroxlav no I know what command to run :)

@miroxlav but you still have to install winpcap.org and microsoft.com/download/details.aspx?id=40784

miroxlav

4:40 PM

ok, then I'm downloading the installer

rany

@miroxlav what installer?

miroxlav

setup.exe for nmap

rany

@miroxlav so you aren't downloading the command-line version?

miroxlav

I already did but after you said that it still needs additional installs, it can be more comfortable to install them all at once by setup.exe

OK, installed

rany

@miroxlav open zenmap

miroxlav

4:44 PM

done

rany

@miroxlav OK, could you send me screenshot of your screen?

miroxlav

there was no scan. the window is empty. are you sure you want the screenshot now?

rany

@miroxlav wait a minute.

@miroxlav I am just trying to remember which command to run

@miroxlav long time since I last used nmap

@miroxlav put 192.168.0.34 in the target field

miroxlav

ok I did

rany

@miroxlav is there a way to change the operation?

miroxlav

4:53 PM

what operation do you mean?

rany

@miroxlav umm maybe profile?

miroxlav

yes. In the meantime I ran several scans (under various profiles) against the address. it appears it is the localhost - strange

rany

@miroxlav ah your IP is 192.168.0.34

@miroxlav your private IP is 192.168.0.34

@miroxlav now change the target to 192.168.1.1

miroxlav

if you check "ipconfig /all" in the question, the IP 192.168.0.34 is not mentioned there at all

rany

@miroxlav strange...

miroxlav

4:58 PM

I have re-checked it right now

so the question is from where it comes

rany

@miroxlav according to nmap your computer's IP is 192.168.0.34

@miroxlav I thought nmap could help :/

miroxlav

yes but I can find it nowhere else in Windows

probably some software or service is interfering, but which one?

rany

@miroxlav did you rescan but change the target IP to 192.168.1.1

nixda

Question: Can you rule out that no other network adapter is the cause? I'm looking at "Wireless LAN adapter Local Area Connection* 12", Ethernet adapter OpenVPN, Ethernet adapter Team Viewer VPN. Maybe create a system restore point, uninstall their respective software and resore that point afterwards

miroxlav

@nixda – I'm very sorry, I'm not going to uninstall them. but I can disable them for a moment

@rany – the scan is still running....

rany

5:03 PM

@nixda @miroxlav open devmgmt.msc from run

@miroxlav disable the adapters @nixda metioned to check if they are the source of the problem

@miroxlav but dont disable "Wireless LAN adapter Local Area Connection* 12"

@miroxlav it is important

miroxlav

@rany – I'm very sorry, your request to "not disable *12" has come too late

I already disabled all adaptors, then re-enabled them

rany

@miroxlav did it help?

miroxlav

and now, 192.168.0.34 is gone

rany

@miroxlav so is your problem solved?

miroxlav

yes. one of adapters was creating that IP address even if it was not reported in ipconfig /all

nixda

5:09 PM

As I thought :)

miroxlav

do you have any experience with this?

have you already seen that somewhere?

rany

@miroxlav OK. Good job @nixda :)

nixda

Not in particular. Would be good to know which one of these adapters was the cause

miroxlav

before, Hyper-V network adapter was causing problems to me

rany

@miroxlav interesting

miroxlav

5:11 PM

not this specific problem, but they were strange, e.g. inability to connect anywhere etc.

I suspect it was that adaptor again

as you said "*12"

rany

@miroxlav what do you mean "*12"

miroxlav

"Wireless LAN adapter Local Area Connection* 12"

rany

@miroxlav do you mean it caused all of this?

miroxlav

I checked that all 3 Hyper-V machines are off.

Answer to your question: I suspect so, because in the past it did it. (I tracked that down before.)

To me it seems, it has somewhat unstable behavior / driver.

nixda

That "*12" means something installed this adapter over and over again and increased the counter, not?

rany

5:15 PM

@miroxlav It is installed by default on WIndows 8, 8.1, 10 to connect Wi-Fi direct devices using the Windows Pairing experience user interface

miroxlav

@nixda – yes. I cannot see older ones, otherwise I would remove them somehow. that *12 looks disturbing.

nixda

ok then, have a nice day. bye all

rany

@nixda bye :)

miroxlav

@rany – oh... perhaps I was wrong this time. so you say that "Wireless LAN adapter Local Area Connection* 12" is not connected to Hyper-V?

rany

@miroxlav absolutely not

@miroxlav it isnt related to hyper-v whatsoever

@miroxlav it is very important for some features in Windows to work

miroxlav

5:18 PM

I see. wait. I cannot see "Wireless LAN adapter Local Area Connection* 12" in the list of adaptors I disabled. SORRY for confusion

so I did not disable that one, I just created the confusion

rany

@miroxlav did you disable Microsoft Wi-Fi Direct Virtual Adapter

miroxlav

I disabled these:
• Hyper-V Virtual Ethernet
• Bluetooth Network Connection
• Team Viewer VPN
• OpenVPN

rany

@miroxlav OK, but I don't think Hyper-V could interfere

miroxlav

@rany no, I can't see "Microsoft Wi-Fi Direct Virtual Adapter" in the list

rany

@miroxlav could you try to renable it?

miroxlav

5:20 PM

all are re-enabled now

rany

@miroxlav could you ping 192.168.1.1?

miroxlav

I just disabled them all and then re-enabled immediately

now it work correctly

let me disconnect from wi-fi for a moment

rany

@miroxlav OK

@miroxlav Are you still facing the same issue after re-enabling them?

miroxlav

no, 192.168.0.34 is gone since the first disable/enable cycle

solved...

rany

@miroxlav Great.

miroxlav

5:28 PM

I'm still not sure which adaptor backed it and why, but now it can' be figured out

thank you for your dedicated assistance.

rany

@miroxlav I think one of your VPN clients failed to connect and ended up connecting to nothing

@miroxlav This happens alot w/ OpenVPN

miroxlav

ok. I try to uninstall OpenVPN, currently I almost don't use it.

btw how you can create the chat room for the question? I cannot see any link in the question to do that.

rany

@miroxlav chat.stackexchange.com/rooms/new

@miroxlav I just named it the question's name :)

@miroxlav and left the description field blank

miroxlav

oh, OK, so there's no link to the question :) haha

thank you very much rany again

rany

no problem @miroxlav :)

miroxlav

5:34 PM

perhaps you can add an answer and I'll accept it

rany

@miroxlav OK.

@miroxlav done :)
