TDMS problem with spikes

Hello guys,
At first, I'm a bloody beginner using SignalExpress and DIAdem :-/
I recorded some data (signals of two acceleration sensors) using SignalExpress 2010.
Now I want do open them with DIAdem for post processing ... reading the TDMS files works but the data seems to be corrupted somehow.
There are spikes (>1E+300) in the signal sequence which shouldn't be there (I don't see them when I open the file in SE2010).
Please see the attatched screenshot (it explains the problem better)
Greetings
Marius

Hello YongqingYe,
OS language is German (Windows XP), SE2010 language, too.
I only used standard ASCII characters as far as i know.
At the moment I dont't have the chance to start a new measurement.
I'm looking for the device name (portable NI device, I noted it down somewere).
I attached the meta.txt file thats created while using SE.

Admiright Problem with Tdms Excel Automation

Hi
i have a problem with the TDMS Excel Plugin. I normally have now Administrator Rights on my Computer. So i got the Administator Rights to install the TDMS Excel Plugin. After i had the rights, i installed the Plugin and everything works fine. Then i wrote a VBA script with automatically imports TDMS Files and Copy &Paste Values in a new Excel sheet. Thes macro also works fine. After a while i lost my Admin Rights and i am a "Normal" user again. But with no more Admin-rights my macro doesn't work any longer. There is a error messange which tells me that " ...only a Administator can connect or disconnect the Plugin..."
The normal manual import with the Plugin still works.
Can anybody help me with this probblem?
Thanks

Reading TDMS files in Matlab - problems with the example code

I want to use the TDMS files to store data and do offline analysis in Matlab, version 2009b (either on Mac OS10.6 or Windows XP).
To test the data import in Matlab I tried the example from http://digital.ni.com/public.nsf/allkb/0EEADA99DC7D00A4862572E30037C3A2 , but without success.
I tried either with and without the path definition (as explained on the page I referred to before) at the start, and got back the following errors:
with:
??? Error using ==> loadlibrary>deltempfiles at 559
nilibddc_m.i.
Error in ==> loadlibrary at 452
deltempfiles(delfiles);
Error in ==> Read_TDMData at 7loadlibrary([examplePath '\nilibddc'], hfile);
without:
??? Error using ==> loadlibrary>deltempfiles at 559
nilibddc_m.i.
Error in ==> loadlibrary at 452
deltempfiles(delfiles);
Error in ==> Read_TDMData at 36loadlibrary(NI_TDM_DLL_Path,NI_TDM_H_Path);
I found a few messages on the issue, dating from 2006 and 2007, that didn't lead to a satisfying solution and was hoping that, by now, there would be a solution to my problem.
Thanks a lot

Solved!
Go to Solution.

Hi Musk,
Thanks for your answer.
Unfortunately it didn't help as my problem is not discussed there. I have a problem with this line:
loadlibrary(NI_TDM_DLL_Path,NI_TDM_H_Path);
I said before that I was using 2009b, but I was mistaken, I have R2008a, but the 'loadlibrary' is opened in a 2008b editor (no idea why). On the Mac I have 2009b installed.
Thanks
Remco

MacBook Pro 15" Late 2011 Problems with iMac 27" Late 2009 TDM

Hi,
I just got problems with my iMac 27" Late 2009 (Mini-DisplayPort) and my MacBook Pro 15" Late 2011 (Thunderbolt).
When I try to use my iMac as external monitor for my MacBook, there are massive glitches and graphical bugs on my second screen.
I bought a MDP-to-MDP wire from Belkin which works perfect on other computers.
I tried these things:
- Disconnected MagSafe from MacBook + unplugged all USB devices + switched graphics to discrete.
- Shut down all computers ... then booted MBP, iMac and triggered CMD+F2
- SMC, PRAM reset on both devices
The cable works, because:
17" MacBook Pro Late 2011 works perfectly on my iMac screen with my Belkin wire!
I connected my MacBook Pro 15" to a 27" Cinema Display and it works flawless.
After that I plugged it out and tested it again with my iMac screen -> suddenly it works.
Retriggering CMD+F2 or replugging breaks it again with massive bugs.
The MacBook Pro 17" is on 10.7.2, 15" is on 10.7.3, but I also tried to trigger dual screen in 10.7.0 setup with the same issue.
Maybe its a problem with the internal 6750M of my MacBook Pro 15"?
The 6770M of the 17" is working well.
Sample Video:
http://www.youtube.com/watch?v=W_pgc52syes
All updates/firmware updates of iMac and MacBook Pro are installed.
Any solutions?
Greets,
Kai

Problem with htmldb 2 (Sorry APEX)!

I installed htmldb 2 on a windows XP, Oracle 10gR1 (which has enhanced by companion CD downloaded form Oracle's site). Everything went OK but when I want to connect to it by this url: http://localhost:7777/pls/htmldb it takes my username,pass but says:
"Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

I noticed many differences between my installed Apache and documents of htmldb. I run a 9.0.4.0.0 Apache server and the dads.conf and httpd.conf are as following:

# Based upon the NCSA server configuration files originally by Rob McCool.
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://www.apache.org/docs/> for detailed information about
# the directives.
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
# After this file is processed, the server will look for and process
# E:\oracle\product\10.1.0\Companion\Apache\Apache/conf/srm.conf and then E:\oracle\product\10.1.0\Companion\Apache\Apache/conf/access.conf
# unless you have overridden these with ResourceConfig and/or
# AccessConfig directives here.
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do not begin
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"
# with ServerRoot set to "E:\oracle\product\10.1.0\Companion\Apache\Apache" will be interpreted by the
# server as "E:\oracle\product\10.1.0\Companion\Apache\Apache/logs/foo.log".
# NOTE: Where filenames are specified, you must use forward slashes
# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").
# If a drive letter is omitted, the drive on which Apache.exe is located
# will be used by default. It is recommended that you always supply
# an explicit drive letter in absolute paths, however, to avoid
# confusion.
### Section 1: Global Environment
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
# ServerType is either inetd, or standalone. Inetd mode is only supported on
# Unix platforms.
ServerType standalone
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
# Do NOT add a slash at the end of the directory path.
ServerRoot "E:\oracle\product\10.1.0\Companion\Apache\Apache"
# PidFile: The file in which the server should record its process
# identification number when it starts.
PidFile logs/httpd.pid
# ScoreBoardFile: File used to store internal server process information.
# Not all architectures require this. But if yours does (you'll know because
# this file will be created when you run Apache) then you must ensure that
# no two invocations of Apache share the same scoreboard file.
ScoreBoardFile logs/httpd.scoreboard
# In the standard configuration, the server will process httpd.conf (this
# file, specified by the -f command line option), srm.conf, and access.conf
# in that order. The latter two files are now distributed empty, as it is
# recommended that all directives be kept in a single file for simplicity.
# The commented-out values below are the built-in defaults. You can have the
# server ignore these files altogether by using "/dev/null" (for Unix) or
# "nul" (for Win32) for the arguments to the directives.
#ResourceConfig conf/srm.conf
#AccessConfig conf/access.conf
# Timeout: The number of seconds before receives and sends time out.
Timeout 300
# SendBufferSize: controls setsockopt() call made to set send buffer size on
# all sockets. Default OS value on most Windows platforms is too small.
# Larger values can help if the average page size served by OHS is
# large (~64 k)
SendBufferSize 16384
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
KeepAlive On
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
MaxKeepAliveRequests 100
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
KeepAliveTimeout 15
# Apache on Win32 always creates one child process to handle requests. If it
# dies, another child process is created automatically. Within the child
# process multiple threads handle incoming requests. The next two
# directives control the behaviour of the threads and processes.
# MaxRequestsPerChild: the number of requests each child process is
# allowed to process before the child dies. The child will exit so
# as to avoid problems after prolonged use when Apache (and maybe the
# libraries it uses) leak memory or other resources. On most systems, this
# isn't really needed, but a few (such as Solaris) do have notable leaks
# in the libraries. For Win32, set this value to zero (unlimited)
# unless advised otherwise.
# NOTE: This value does not include keepalive requests after the initial
# request per connection. For example, if a child process handles
# an initial request and 10 subsequent "keptalive" requests, it
# would only count as 1 request towards this limit.
MaxRequestsPerChild 0
# Number of concurrent threads (i.e., requests) the server will allow.
# Set this value according to the responsiveness of the server (more
# requests active at once means they're all handled more slowly) and
# the amount of system resources you'll allow the server to consume.
ThreadsPerChild 50
# Server-pool size regulation. Rather than making you guess how many
# server processes you need, Apache dynamically adapts to the load it
# sees --- that is, it tries to maintain enough server processes to
# handle the current load, plus a few spare servers to handle transient
# load spikes (e.g., multiple simultaneous requests from a single
# Netscape browser).
# It does this by periodically checking how many servers are waiting
# for a request. If there are fewer than MinSpareServers, it creates
# a new spare. If there are more than MaxSpareServers, some of the
# spares die off. The default values are probably OK for most sites.
#MinSpareServers 5
#MaxSpareServers 20
# Limit on total number of servers running, i.e., limit on the number
# of clients who can simultaneously connect --- if this limit is ever
# reached, clients will be LOCKED OUT, so it should NOT BE SET TOO LOW.
# It is intended mainly as a brake to keep a runaway server from taking
# the system with it as it spirals down...
#MaxClients 150
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, in addition to the default. See also the <VirtualHost>
# directive.
#Listen 3000
#Listen 12.34.56.78:80
# BindAddress: You can support virtual hosts with this option. This directive
# is used to tell the server which IP address to listen to. It can either
# contain "*", an IP address, or a fully qualified Internet domain name.
# See also the <VirtualHost> and Listen directives.
#BindAddress *

# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available before they are used.
# Please read the file README.DSO in the Apache 1.3 distribution for more

### Section 2: 'Main' server configuration
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <VirtualHost> definition. These values also provide defaults for
# any <VirtualHost> containers you may define later in the file.
# All of these directives may appear inside <VirtualHost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
# Port: The port to which the standalone server listens. Certain firewall
# products must be configured before Apache can listen to a specific port.
# Other running httpd servers will also interfere with this port. Disable
# all firewall, security, and other services if you encounter problems.
# To help diagnose problems use the Windows NT command NETSTAT -a

# ServerName allows you to set a host name which is sent back to clients for
# your server if it's different than the one the program would get (i.e., use

# Note: You cannot just invent host names and hope they work. The name you
# define here must be a valid DNS name for your host. If you don't understand
# this, ask your network administrator.
# If your host doesn't have a registered DNS name, enter its IP address here.
# You will have to access it by its address (e.g., http://123.45.67.89/)
# anyway, and this will make redirections work in a sensible way.
# 127.0.0.1 is the TCP/IP local loop-back address, often named localhost. Your

# Please see the documentation at <URL:http://www.apache.org/docs/vhosts/>
# for further details before you try to setup virtual hosts.
# You may use the command line option '-S' to verify your virtual host
# configuration.
# Use name-based virtual hosting.

Firstly, there's no such thing as Apache 9.3, there's Apache 1 (and subversions) and Apache 2 (and subversions). Your error message -
Oracle-HTTP-Server/1.3.28Shows you're using Apache 1.3.28
Secondly, I'm confused by your comment -
I do not have Apache 9.3 or higher but I think oracle should offer this in its companion CDOracle does offer the Apache server, if you're saying you didn't get it from Oracle then where did your Apache server come from?
Thirdly, I notice from your config file -
ErrorLog "|E:\oracle\product\10.1.0\Companion\Apache\Apache\bin\rotatelogs logs/error_log 43200"That you're piping the logs through rotatelogs, are you sure the logfiles haven't just been renamed?

Problem with Configuring Tomcat for running jsp web applications..Plz HELP

I am using Tomcat 5.5 and Jdk 1.5.0_12 and Oracle 10g. I am using jdbc-odbc bridge connection

WEB-INF folderand in that I have lib folder which contains catalina-root.jar

I have set the context path to /tdm in the server.xml file. Should this be placed in context.xml?
My first page in the project is called Homepage.html. To start my project I give http://localhost:5050/tdm/homepage.html

a valid.jsp file, where I connect to the database and check and use jsp:forward to go to next pages
accordingly. However when I enter the username and password and click Go in the homepage, nothing is
displayed on the next page. The URL in the browser says valid.jsp but a blank screen appears.

Is there any other thing that I need to set in classpath? Should I have my project as a
WAR file in the webapps of TOMCAT or just a folder i.e. directory structure will fine?

Is this yet another problem with 7.5 or is it just me . . .

Upgrade seemed to be fine, at first . . . now I keep getting distortion on songs. It seems to be quite random and just because a song has been distorted when I've listened to it once doesn't mean it will be when I listen to it again! It's driving me insane. Is this yet another bug or have I done something wrong (apart from upgrading to 7.5).

Hi Emlou,
If you have a Windows based operating system such as XP -
It seems to me that you are suffering what I am having the same problem with - the program takes up to much of your computer's processing usage. If you go into your task manager and watch performance as ITunes runs - you will see how much of the total computer usage it is taking at any given moment - that's why your songs are distorted, slowing, garbled, etc - the usage on mine spikes from 11% - 93% AT ANY GIVEN MINUTE! I have no idea why, but I have found that by going to your "Control Panel" and clicking on Quicktime you can adjust audio output to help. Click the audio tab, click Safe Mode Wavout only (checkbox) / Then adjust the "Rate" to 96kHz / Then adjust the "Size" to 16 bit. Close that and shut down and restart Itunes - it might help a little for you.
Maybe someone out there can help us find out why we are suffering with all the CPU usage trouble and how to adjust that spiking.
Thanks!

Problem with writing continuous data to excel using using Report Generation vi's

Hey Everyone,
I am trying to read the data from DAQ and write to excel continuously using Report Generation vi's.
But when I run the VI, it writes only one interation of the while loop (gathering data from DAQ continuously) and doesn't append the data into the same file when I run it again after stoping the VI.
I have attached the VI i created. Please let me know if you have any idea to solve this issue.
Thanks

There are two problems with your VI. First, the basic logic of writing/appending to a file (Excel, TDMS, anything) should go something like this: Open the file, position yourself at the end of the file, then, in the loop, acquire data and write it to the file until you are finished with data acquisition. When you exit the acquire/write to file loop, then close the file. In particular, the opening and the closing of the file should not be inside the loop.
As others have pointed out, writing to Excel might not be optimal, particularly if you are acquiring data at a high rate (and would therefore be writing a lot of data). We actually use Excel in our data acquisition routine, mainly reading from a WorkSheet to get the parameters of a particular stimulus, but also writing the outcome of the response to the stimulus. As it happens, our "acquisition rate" in this example is on the order of several samples per minute, so there's no problem using Excel (we also sample 16 channels of analog data at 1 KHz -- this gets written as a binary file).
Second, if you really do want to use Excel, use the (existing) Excel file to which you want to append as the "template" argument of the New Report function. Then use the Excel Get Last Row function to position yourself at "end of file", as noted above.
Good Luck.

Problem with output from report to excel, calling the report from form 10g

Hi everyone, I'm having a problem generating a excel from a report, which is called from a form, I'm using Forms 10g. The problem is this: My report has a variable number of columns. These columns appear according to data obtained from the database, these columns are dates, In vesion 6 excel file generated shows the columns one after another starting in column A1 to column CP. I mean that the dates are correlative. But in version 10g the excel file generated shows the same report starting in column A to column T, only shows the 20 dates correlative corresponding to this columns, the rest of the dates are down the excel sheet in groups of 20 dates, it's something, the file in 6i grows across and in 10g grows down the excel sheet. The report (rdf file) is the same in 6i and 10g, I compiled the 6i version to obtain the 10g version. The excel sheet generated in 10g looks like the report was in pdf format, because PDF format, cuts the report in pages and the file grows down, if I generate the report in PDF format it has the same structure excel file in 10g has. I hope yo can help because I have days trying to solve this but I have no succes. If someone could help I could email the excel files generated in two versions. Here I put the code I use to generate the files in 6i and 10g. I have tried with DESFORMAT=SPREADSHEET in 10g but the result is the same. Thanks for your help. Greetings for all.
Code for version 6i (Works Very well)

Itunes 7.0.1 skipping problem with audigy soundcard

Hi, I have an audigy se soundcard and running itunes 7.0.1. Whenever the cpu usage spikes (opening applications and loading animations on webpages) and I'm playing music in itunes, the music skips and cracks. I don't think it's issue with soundcard/driver cuz winamp works perfectly fine with no skips. I've tried changing audio pref (tried 8, 16, 24 bit and 32, 44.1 and 48 khz) in quicktime, all of which did't work. I don't want to change the process priority for itunes cuz i have to do it every time. Any ideas? This doesn't happen with onboard audio so it's really weird. I want to be able to use my soundcard. Thanks.

Did you try turning your hardware acceleration setting down? I was having the same problem with the previous version of iTunes and was advised to change my acceleration setting from "full" to "basic". If you want to try this, go to the control panel>sounds and audio devices>audio tab>sound playback advanced button>pull the acceleration lever down two notches from Full to basic. Restart itunes and see if that helps.

Problems with a WRT54G wireless linksys router.

Hello, I'm having problems with my WRT54G linksys wireless router.
With this router, I tend to get lag spikes and often disconnect while playing online games at a certain time. The spikes usually get worse
during the afternoon/evenings (2pm-12am PST).
Some information about my setup:
Firmware version: v.8.00.7
Shaw high speed cable (i think ~10mbit connect)
xp/vista OS (two computers linked up via router)
- Both computers are connected via wire, not wireless
I've changed settings for my router through advice, but nothing seems to work. Nobody else is connected to my router because I get nothing
in the logs and the DHCP client list has only 2 IPs. I'm sure my router is the one giving me lag spikes because I sometimes connect my
modem directly to my computer (the XP) and receive no lag spikes. Someone does use wireless, but I turn wireless off at times so that
isn't the problem. I've also secured my wireless, so I know it isn't the problem.
Anyone know what's causing these lag spikes and how I can fix it? Do I need a new router?
If anymore information is needed, please do not hesitate to ask.
Message Edited by Dysouk on 10-17-2009 12:24 AM
Not so computer savvy

Try to readjust the wireless settings of the router...Open the linksys setup page and try the following settings...
- Reduce the MTU size to 1364.
- Change the Wireless Channel to 11-2.467GHz.
- Under Advanced Wireless Settings,Change the Beacon Interval to 75,Fragmentation Threshold to 2304,RTS Threshold to 2304
Now,check the difference...If you are still facing the same problem then,try to upgrade/reflash the router's firmware,reset the router and reconfigure it from the scratch.

Video -data viewing problem with diadem 10.1 and 10.2, while ok in diadem 10.0

Hi,
When viewing a video in combination with data channels (we have 3 EEG channels, tdm data, that we watch in parallel), diadem crashed rapidly when playing the video and data together in Diadem 10.1 and 10.2. We do not have any problems with Diadem 10.0. so we keep on using the older version to avoid any troubles. This just to notify, since other people may have the same trouble.
Cheers
Else

Hi Else,
We'd really like to reproduce this problem and get to the bottom of what is causing it, so that you could upgrade in the future. Would you be willing to send me a data set consisting of your TDM, TDX, TDV, and video file? You can either post here or send it directly to my email at:
[email protected]
Thanks,

Problems with perfviewer

Dear SDN,
I am running ep6 sp2, patch 28. I am having a problems with the perfviewer. I am getting an "internal server error 500", when I try to access the "User sessions overview"
Thanks
Jeremy Baker

Hi Jeremy,
I was having the same problem and I would also notice that the CPU would spike when I got these error messages. I entered a OSS Message with SAP and they updated note 766839 with a new pviewer.ear file you need to deploy.
Hope that help.

Nilibddc dll: opening tdms files with corrupt index files

Hi there,
i have a question regarding error handling, when using the nilibddc.dll.
I want to use nilibddc.dll to open .tdms files. At the time i'm experimenting with some error cases and got stuck in one case:
When i try to open a .tdms file with a corrupt .tdms_index file i get the error code -6211 (DDC_StorageCouldNotBeOpened).
The .tdms_index file is corrupt because of errors while copying the file.
The problem i noticed is, that i have a file lock on the corrupt .tdms_index file after DDC_OpenFile(...) (i can rename it, but i can't delete the file!?).
As you can see in the code snippet - it isn't really special...
int ddcError = 0, length;
DDCFileHandle file = 0;
ddcError = DDC_OpenFile (FILE_PATH, NULL, &file);
// here i get ddcError == -6211
if( ddcError == 0 )
// do something with the file...
ddcError = DDC_CloseFile(file);
if( ddcError == 0 )
cout << "no error - everything done" << endl;
system("PAUSE");
Do i miss something here? Should i use DDC_FreeMemory in somehow to release opened handles?
I also tried to use the DDC_OpenFileEx(...) with readOnly set to true. But this doesn't change anything!
Thanks in advance for help,
Daniel
Solved!
Go to Solution.

Hi there,
thanks for the replies (and sorry for my late answer).
The code above is from a simple Visual C++ Project that i use to run some tests with the dll.
If i posted the question in the wrong topic please let me know - i found some other posts dealing with the dll so i thought i'm right here.
I attached a tdms and the corresponding "corrupt" tdms_index file.
The file handle stays 0 when i debug my code with that file and i receive the error -6211.
I want to use the dll as part of an application that runs as system service. It reads and writes information from/to existing tdms files. After the information is read the application moves the files. So, if the tdms_index file gets corrupt (by whatever) i have the problem, that the index file is locked as long as the service is running and the file can't be moved. I can't tell how often this happens (hopefully never) but if i can do something against it, i would like to integrate this precaution.
Thanks in Advance for any information & have a nice day,
Daniel

Problems with LP9 and VSL

I've been having some problems with Vienna Symphonic Library (Special Edition) and LP9. I'm trying to create an orchestral template using some of the settings from the Special Edition Demo provided on the VSL site. About half the time I've tried to import the tracks (using the media browser) Logic has stalled/crashed. I have been able to get all the files imported, but now I have two more problems. Logic has crashed most of the times I've tried to reopen this template. Also, when I am able to open the file I'm getting a huge spike in the meter for one of my cores while using the VSL instruments. Playing notes with any of the instruments selected causes a noticeable spike, but each time I select a new instrument and play it adds to the spike, such that after playing notes in several instruments the meter is maxed out (as shown in pic). Pressing play and then stop temporarily corrects the spike, but it returns over an over.
I know that having a software instrument selected is more strenuous on the system, but it shouldn't cause a cumulative build-up as I have described, right? My system specs are as in my signature, and both the activity monitor and VSLs instrument plugins show that I have 2GB+ RAM available. My buffer is set to 256. This may not be a VSL specific issue, as I have seen unusually high spikes using other sampler instruments, but not to the same extent. The spike always appears in the last core.
Any thoughts/trouble shooting tips? Thanks.

I'm still wondering why it happens now at this moment in time...
PC does seem to be a bit odd & inconsistent, the few times I've tested with it, at least so far as we content filtering goes; and if I remember rightly, you're not the first to report previously ok settings suddenly preventing some or all internet until pc is switched off altogether.
It may work when re-enabled
