I am running Windows 7 and want to disable the internet connection to keep my system safe after January 2020. I have a desktop Dell Optiplex 780 but the wifi connection on the tower was blown by lightning a while back and I am connecting via a USB adapter, Linksys Wireless Adapter AE1200. What is the best or easiest way to keep this system disconnected from the internet and yet easy to connect if need be? I see all sorts of options, including using Device Manager or the Internet connection icon in the Systray. I'd like to boot up without the computer connecting to the internet; that is, remaining disabled until I want to enable it. Thank you.

You could change the setting through the systray so that it doesn't connect automatically. You would need to connect manually.
I have switched to linux on my windows 7 machine just in the last few days. It boots up faster and closes faster and most of what i need is available on linux (i'm using Ubuntu). Except for some software that is no longer supported due to windows dropping silverlight. The best part is that all software is downloaded from the Ubuntu site like Apples app store so it less likely to be infected by malware. It's all open source so many developers inspect the software for malware. The other good thing is that it doesn't have a life cycle like windows where you need to get a new computer due to your old one not being able to run a new version of the OS.
Edit: You can create a dual boot on your machine if you like one for windows 7 and one for linux. You can also download a Linux ISO to a usb stick and boot off that to try Linux ( it doesn't replace your windows )

Would a good antivirus not do? as ... Malwarebytes, etc.?

Hi laverne,
The setting you want is in the WiFi adapter properties settings.
For Windows 7:
Click Start menu and type Network and Sharing Center. Usually shows above after Network is typed in. Select Network and Sharing Center. In the left pane select Change adapter settings. This will show your WiFi connection. Click to open the Wireless Network Connection an this will open the Wireless Network Connection Status box to the General tab. On the General tab click the Wireless Properties button to open that properties box. On the Connection tab of the Wireless Network Properties box about mid way down is the statement Connect automatically when the network is in range. Uncheck this and Windows will not connect until you manually connect by Enabling the Wireless network adapter. Be sure to click OK after making the changes to save those changes.
I hope this is what you want.

Thank you all for your replies. Dana, that's exactly the information I wanted and have tried it both on my Win7 desktop and my Win7 laptop. It works great! And it is simple to re-connect when that is desired. Laverne

Hi laverne,
I glad that's what you wanted. Just how simple is it? If you desire I could show you how to set this up so one click turns the adapter on and one clicks turns it off. All from the Desktop.

Dana, Well, yes, it is simple and takes 3 clicks. The clicks are not the problem. The problem is that I won't remember how to disable and re-connect to the internet as time goes by on these old computers; therefore, I have to keep notes atop the computers. Yes, I definitely would like a one-click solution on my Desktop to disable and re-connect, so I can do away with Notes. Many thanks. Laverne

Hi Laverne,
I will be happy to show you how. The process may show you how to streamline other tasks you do. It is really very simple to do, but will appear strange in how we accomplish it. This is how I come up with my tips and hacks to do things easier…how can I make a repetitive task easier or automatic.
This is a brief summary of what we are going to do. You can disable and enable the WiFi adapter with a command. We will create .bat files, one with the command to enable the adapter and one with the command to disable the adapter; and save these .bat files to your HD. We will create a new Task in Task Scheduler for each of these .bat files (I’ll explain why below). Next, we will create shortcut for each of these scheduled tasks. Clicking the shortcut for the task will cause the task to run which will run the .bat file and execute the command. One shortcut to disable the adapter and one shortcut to enable the adapter.
Why run the .bat file as a scheduled task? For the commands to work, they must run with administrative privileges. You can run the .bat files with administrative privileges using a shortcut to the .bat file or right clicking the .bat file and selecting Run as administrator, but this will cause the User Account Control box to open requiring authorization that you must respond to (click) to run the .bat file. That makes the process a two click process. If you create a new task of running the .bat file in Task Scheduler you can pre-authorized administrative privileges for the task. This means the .bat file will run with administrative privileges with no UAC box opening. Running the .bat as a scheduled task (without a schedule) will result in only one click on the shortcut to run the .bat file and cause the adapter to enable or disable.
The first part is the command needed. Since you had problems with the internal WiFi, we need to see how your system is set up with the USB WiFi adapter.
I need you to open a command prompt as administrator. Win Key + R to open Run box type in cmd Ctrl+Shift+Enter and OK UAC box
Enter the following command
netsh_interface_show_interface
Replace _ with space
I need to know what it displays.
Next, enter the following command
wmic_nic_get_name,_index
Replace _ with space
This will list all adapters (virtual, miniports, etc.). Look for your USB WiFi Adapter (usually will have the name of the maker like Linksys). I need to know the Index number for that adapter.
Post back the info and I’ll make the commands for you. If the show interface has only one WiFi showing, then I can use the netsh commands. If I have to distinguish between two WiFi adapters then I need to use the wmic commands with index identifier.

Hi Dana -- Below is the info from the two commands you sent. Number 11 (Linksys AE1200) is my Internet adapter in the 2nd command. Dana, I always run everything as administrator and never get that UAC message. So it is fine with me to make two shortcuts without scheduling the tasks if you think this is what I should do. It is interesting to know there is a way around this when not running as administrator. After doing the desktop computer with the external internet adapter, can we later do my laptop enable/disable which just has a wireless connection? Please. I also run this computer as administrator. Laverne
C:\>netsh interface show interface
Admin State State Type Interface Name ------------------------------------------------------------------------- Enabled Disconnected Dedicated Local Area Connection Enabled Connected Dedicated Wireless Network Connection
C:\>wmic nic get name, index Index Name 0 WAN Miniport (SSTP) 1 WAN Miniport (IKEv2) 2 WAN Miniport (L2TP) 3 WAN Miniport (PPTP) 4 WAN Miniport (PPPOE) 5 WAN Miniport (IPv6) 6 WAN Miniport (Network Monitor) 7 Intel(R) 82567LM-3 Gigabit Network Connection 8 WAN Miniport (IP) 9 Microsoft ISATAP Adapter 10 RAS Async Adapter 11 Linksys AE1200 12 Teredo Tunneling Pseudo-Interface 13 Linksys AE1200 14 Microsoft ISATAP Adapter

Hi laverne,
If you don't get the UAC box when opening the command prompt with administrative privileges, then you are correct in not needing to use the Task Scheduler. Anyway, it is a neat (net) trick to know (sorry for the pun). This will be even easier. Since the netsh interface shows only one WiFi network named Wireless Network Connection, we will use the netsh command as it is easier to enter. Open Notepad Enter the following command on the first line of Notepad:
netsh_interface_set_interface_"Wireless_Network_Connection"_ enable
Replace the _ with a space. Select File>Save as In the Save as type: box select All Files (*.*), enter WiFiON.bat as the name, and select a location to save this bat file. This will be the .bat file that will turn the adapter on.
Return to the command in Notepad and change enable to disable. Select the Save as option as before with All Files as file type and the name as WiFiOFF.bat. This will be the .bat file that will turn the adapter off.
You can test these .bat files by clicking them and checking your connection. If they don't work, right click the files and select Run as administrator and see if they work then. If they work, then the .bat files will need to be ran with administrator's privileges.
Now make shortcuts for each of these files to keep on the Desktop. I would name them WiFi On and WiFi OFF. If you found out that the .bat files have to be ran with administrative privileges, change the shortcut as follows: Right click and select Properties Select the Shortcut tab Click the Advanced button to open the the Advanced Properties box Place a check in box for Run as Administrator Click OK...Apply...OK to save changes.
You can also change the icon for the shortcut making it easy to identify ON from OFF.
Let me know how it goes.

Hi Dana,
You make it SO EASY, even giving me the names of the shortcuts, etc. Yes, both bat files (shortcuts) worked great; I did not need admin privileges. I will do the same procedures on my Win7 laptop. Thank you ever so much. Do you think I am safe online for a month or so on Windows 7? Laverne

Hi laverne,
Glad all went well and you got what you want. Yes, you'll be safe for a while. Do you run any security suite such as Norton or McAfee? Not just Anti-virus, but a security suite. Such a security suite has multiple coverage such as firewall, e-mail, internet, etc. Such a security suite is better than Windows security even when Windows 7 had frequent security updates. I run 2 Windows 7 systems and 3 Windows 10 systems on my home network. I cover all with a total security suite that allows 10 devices for my one yearly subscription. My cost comes to $0.06 per PC per day.
Even with Windows 7 no longer getting security updates, I will be using my Windows 7 systems for a long time. The all in one security suite will keep it safe.

Hi Dana, Thank you for your comments regarding Windows 7 safety. I run Avira antivirus, free version, and on occasion, I run a scan with Malwarebytes and MS Security Essentials; Avira is running all the time as my chosen antivirus. I do not run a security suite. May I ask which one you use unless you would rather not say? I believe Avira has a security suite but I've never looked into installing it. I also have a Windows 10 desktop computer and a laptop -- one running Avira Antivirus and the other Windows Defender -- but again, no security suites. It sounds like it is time for me to look into this. Can one run both an antivirus and security suite at the same time? Is it recommended that one use the same company's antivirus program and their security suite rather than having two different suppliers of the software? Again, many questions and many thanks! Laverne

Hi laverne,
Selecting security for your PCs is a multi-facet topic and what's perfect for one user is unacceptable to another. It comes down to what you have to protect, how much protection you feel comfortable with, and the different kind of protection from different types of threats. So let's look at these topics and you decide what will work for you.
The most important items to protect are those connected to your finances and credit standing. The ultimate goal of the bad guys is to get money from their malware attacks. These type attacks come in many different forms….viruses, Trojans, keyloggers, phishing, drive by downloads, ransomware, stack overflow of a port, etc. Basically, every kind of threat out there. You need security software that provides protection for every one of these kinds of attacks IF the PC has files that have information to allow the bad guys access to these sites or allow obtaining credit. If you have more than one PC I suggest this type of information be used only with on one of the PCs and decrease your chances of becoming a victim. Just remember to remove all that data when moving from one PC to another which includes the saved passwords in that browser on that PC. I take this a step further by keeping all such data on a separate external HD that is connected to the PC only when in use. Thus, this data is not on my PC if the bad guys get past my security. The best solution is to limit the exposure of this type of information AND protect yourself against all these kinds of attacks.
Anti-virus software will stop viruses, but virus attacks only represented 10% of all malware attacks in 2018. You need to stop Trojans and many anti-virus software will also protect from Trojans which makes up another 10% of malware attacks. So Anti-virus software alone will protect you against 20% of all attacks out there. Anti-keylogger software is different from anti-virus software and the same for many of the different kinds of attacks such that protection requires a different type of anti-malware application for each of these different kinds of attacks . You need Internet security thru browser addons to stop drive-by’s, phishing attacks, and bot redirects.
You need all these different kinds of anti-malware applications, but anti-malware applications are very controlling and have to be so in order to provide the protection. Different anti-malware applications may desire the same level of control and fight each other for it. This conflict usually interferes with the protection the applications provide. This doesn’t happen all the time, but routinely happens enough to be concerned when using two different anti-malware applications. One way to avoid this possible conflict is to get a security suite application that has all these different anti-malware applications working under a central control console resulting in no conflicts in control.
I avoid recommending any specific security software, as what is the best for me may be the worst for you because it does depend on your setup. That being said, I will explain what I have and why.
I have 5 PCs on a home network where each of the PCs can access each other over the home network. I have increased security on my router to protect the home network. I keep all personal data on a separate external HD with an on/off switch and only turn it on when using that data. I have Norton 360 installed on all PCs (allows 10 PCs with my yearly subscription). Norton 360 is a security suite that provides all the kinds of malware protection including a VPN. I don’t use the Lifelock services. I chose Norton mostly because it was compatible with the servers where I used to work to allow remote desktop connection. I’ve used Norton for a couple years and like it so much that I renewed it after I retired and no longer needed remote connection. I have only one caution about Norton and that is it is a complex program that uses a lot of resources that will cause no problems on a robust system; however, on a system with a slower processor and minimal RAM could cause a lot of conflict for limited resources. This is why I avoid recommending security software. I use Google’s anti-spam functions to filter my emails before downloading into Outlook and fine tune Outlook to remove spam that gets thru Google’s filters. All those emails are kept on that separate external HD. I also have scheduled system backups (images) on a routine basis…best defense against ransomware and numerous other infections.
I personally feel the annual subscription fee ($99 – on my setup that’s $20 per PC per year) is worth what I get.

Hi Dana,
What a comprehensive write-up on computer security! It almost makes one want to give up computers totally! It is not a simple subject and you did a superb job of explaining.
I probably will buy some security suite and go from there. I do very little financial work on my computer and almost never store passwords -- but all that is needed is one little breach.
Thank you so much, Dana. I think your explanation will be useful to many other computer users in addition to me. Perhaps you should post it on the NNT forum with a subject like "Computer Security" or "Keeping Your Computer Safe" or "What good is an Antivirus, etc" I don't want anyone to miss your comments.
