There are multiple ways to find an IP address on Mac computers running IOS. If your require knowing you IP address, then one of the following methods can help.
Step 1: Using terminal screen. In this process, You need to click command and space button togather to open “spotlight Search” in your Mac machine. Once spotlight Search bar appears, type “terminal” and hit return key. Your terminal window will pop open. In the command line of terminal window, type “ifconfig” and press the return key. You will get several lines of output. Scroll to find something called “en0”. You Mac IP will be listed in this section.
Step 2: Using network window. Open the spotlight Search similar to how we did in step 1. Search for word “wifi” in your spotlight search bar and hit enter. This will open the network detail window. Head to “advanced” button at bottom right corner and click it. In the next step, click on TCP/IP tab at top center. You will see your Mac IP under ipv4 heading here.

WiFi gives wireless waves for the use of internet. There are many devices that uses WiFi to communicate to the wonderful world of internet. Lack of wires make WiFi easier to access and most demanding technology. Most of us are heaving WiFi signals at our home. These signals are broadcasted by a device called Routers. When we opt for an Internet service, our ISP (Internet Service Provider) will provide us with a Router. Alternatively, we can also purchase our own Router.
Our WiFi signal varies by make and model of our Router. Depending upon Router’s brand, we can have a strong or weak signal. No matter whatever router we install at our home, there remains some grey areas where we cannot find optimal WiFi signals. Hence, we may experience slow speed in those areas of home or even no connection. These are called dark areas.
If you do a search on any of the search engine for boosting WiFi signals, you will find thousands of web page suggesting tips and tricks to boost up your WiFi signals. You will also find several device available to boost up your WiFi signals. In this blog, I am sharing with you a very handy technique that you can try at your home to boost up you WiFi signals. I have personally used this trick and the result was worth. My WiFi signals improved about 30 – 40 %
Things to know: Before you go ahead with the tricks mentioned below, it is important to understand how WiFi signals are measured. WiFi signals are measured in a unit called decibel milliwatts (dBm). A signal strength less than -70 dBm is not considered good. For example, a signal strength of -80 dBm is not good and you will encounter internet issue. Please note that higher the number, lesser signal strength it is. For example -80 dBm is weaker than -70 dBm. -60 dBm is better out of these 2 signals.
How Do Routers Broadcast Signals: Home WiFi routers contains antennas. These antennas can be an internal antenna (placed inside the router cabinet) or an external antenna. The signals broadcast from WiFi routers are generally of 2.4Ghz or 5Ghz. In general 2.4 Ghz signals have an average internet speed 10-29Mbps on 802.11g standard and 150Mbps on 802.11n standard. On other hand, a 5Ghz router will have an average speed of 3-32Mbps on 802.11a standard and 210Mbps-1Gbps speed on 802.11ac standard.
Checking Your Current Signal Strength: I would suggest you to download any of the WiFi analyzer software in your phone and read the WiFi signal strength in the areas identified as dark areas. Android phone users can use “WiFi Analyzer” or NetSpot. iPhone user can use “Fing” or “WiFi Analyzer” app for the purpose. As these signals are measured in dBm and their values are negative, you should remember that a lesser negative number is a more powerful signal. Make a note of your WiFi signal strength before proceeding further.
A good WiFi signal must not exceed -70dBm. Signal range from -60dBm to -70dBm are considered below average quality signals.
How to boost up WiFi Signals at Home
Boosting WiFi Signal using Mirror: I bet this is world’s simplest and easy to implement trick. It will cost you nothing. All you need is a small mirror to boost up your WiFi signals by up to 40% strong.
I have a Nokia Router installed by my ISP that has its antenna placed internally. I just placed a mirror at the back of the Router and WOHO!!! The signal strength is now -33dBm. This can be considered as an excellent signal strength. Please see the Image below to understand what exactly I have done.
Boosting WiFi signal using Aluminium foil: Aluminium foils are commonly available in every house. We often use it to keep our food hot. This Aluminium foil works great when it come to boosting your WiFi signals. We can make a simple parabolic reflector using Aluminium foil. It works great and you will see a good difference in your WiFi signals in dark areas of your rooms.
Here is how I have made a simple parabolic reflected using Aluminium foil. I just staple the foil on a hard square paper and placed it behind my Router. It works great. Here is a link to Youtube video on how to make a simple parabolic reflector using Aluminium foil.
Boosting WiFi Signal using Old Router as Repeater: This trick requires a little bit of technical understanding and you should have another working router. I would suggest an old Router that you might have and you are no longer using this. A second Router can be used as Wireless or Wired Repeater.
Essentially, a Wi-Fi repeater extends the coverage area of your existing wireless network by amplifying the signal and then transmitting that signal to a wider area. In short, it receives a wireless signal from your router and rebroadcasts it to another localized area, providing a “bubble” of additional network coverage that you can access when you’re out of range of your router’s finite coverage area.
Here is a detailed instruction of setting up a D-Link DIR-816 as a repeater.
Now that you are aware about the simple yet powerful techniques to boost up your WiFi signals at every corner of your room, its time to enjoy chatting or conferencing from balcony. Enjoy!!
In a recent assignment at my office last week, I came across a situation where I had to make some changes in the VBA code of an excel document. The excel document was something getting used from long time and there was no one having details related to password through which VBA code in that document was protected. Also there was no related supporting document available. I was in a situation where I required getting the access of VBA code without password.
After a lot of search on web and spending quite some time, I was able to access the VBA code without knowing the password. Although there are a lot of information already available on web related to the topic, however most of the information are either in bits and pieces or not very simple to understand for a non techie person.
Hence I decided to write this blog to present the information in simplest manner possible. Give it a try if you are in similar situation and I am sure this is going to work for you as well. Please follow all steps precisely as mentioned.
Before we jump into steps to access the password protected VBA, it make sense to understand how it works. When we try to access password protected VBA document, the VBE (Visual Basic Editor) will call in build system function to create the password dialogue box. This dialogue box is where the user will enter password to access the document and will click on OK. If the user enters correct password and press OK, the system function will return 1. If the user enters incorrect password or click cancel, the system function will return 0. After the dialogue box is closed, the Visual Basic Editor (VBE) will check the value entered. If the value is 1, VBE will think that the password is right and will open the document. On the other hand, if the value is 0, VBE will think that password is incorrect and will not allow access to the document. The trick that we are going to use is basically to swap the value of 0 to 1 by using a code that can be written easily or can be taken from this post and included in your excel document. Hope this basic helps in making the concept a little easier. Lets jump into the steps now.
For the ease of understanding, I have created a sample VBA document called “Password_Test”. As you can see below, when I try to open this VBAProject, it prompts for a password to be entered.
Okay, so now we will go to the steps directly.
Step 1: First step first. make sure you take a backup of your original file and keep it at a different location in your PC or Laptop so that if accidentally we corrupt the file then we have a backup readily available.
Step 2: Create a new file with .xlsm extension.
An XLSM file is a macro-enabled spreadsheet created by Microsoft Excel, a widely used spreadsheet program that comes with every edition of the Microsoft Office suite.
For ease of understanding, I have named this file as “macro.xlsm”. To create this file, open MS Excel application and then go to File->SaveAs->location and then name your file as macro.xlsm. You can also choose file type from drop down.
Step 3: Open you locked VBA project file. In our case, its “Password_Test”.
Step 4: Open the new blank file that we just created. In our case its “macro.xlsm”
Step 5: We need to insert certain code in our new created “macro.xlsm” file. Once the file is open, click “ctrl+F11” to open the Visual Basic Editor. Once your VBE is open, you will see a screen like this.
Step 6: Select VBAProject (macro.xlsm) then go to Insert and click on Module. A blank page will open on right panel of the VB Editor.
Step 7: On the blank page that open on right of VBE, copy and paste below mentioned code:
Private Const PAGE_EXECUTE_READWRITE = &H40
Private Declare PtrSafe Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" _
(Destination As LongPtr, Source As LongPtr, ByVal Length As LongPtr)
Private Declare PtrSafe Function VirtualProtect Lib "kernel32" (lpAddress As LongPtr, _
ByVal dwSize As LongPtr, ByVal flNewProtect As LongPtr, lpflOldProtect As LongPtr) As LongPtr
Private Declare PtrSafe Function GetModuleHandleA Lib "kernel32" (ByVal lpModuleName As String) As LongPtr
Private Declare PtrSafe Function GetProcAddress Lib "kernel32" (ByVal hModule As LongPtr, _
ByVal lpProcName As String) As LongPtr
Private Declare PtrSafe Function DialogBoxParam Lib "user32" Alias "DialogBoxParamA" (ByVal hInstance As LongPtr, _
ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, _
ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer
Dim HookBytes(0 To 5) As Byte
Dim OriginBytes(0 To 5) As Byte
Dim pFunc As LongPtr
Dim Flag As Boolean
Private Function GetPtr(ByVal Value As LongPtr) As LongPtr
GetPtr = Value
Public Sub RecoverBytes()
If Flag Then MoveMemory ByVal pFunc, ByVal VarPtr(OriginBytes(0)), 6
Public Function Hook() As Boolean
Dim TmpBytes(0 To 5) As Byte
Dim p As LongPtr
Dim OriginProtect As LongPtr
Hook = False
pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA")
If VirtualProtect(ByVal pFunc, 6, PAGE_EXECUTE_READWRITE, OriginProtect) <> 0 Then
MoveMemory ByVal VarPtr(TmpBytes(0)), ByVal pFunc, 6
If TmpBytes(0) <> &H68 Then
MoveMemory ByVal VarPtr(OriginBytes(0)), ByVal pFunc, 6
p = GetPtr(AddressOf MyDialogBoxParam)
HookBytes(0) = &H68
MoveMemory ByVal VarPtr(HookBytes(1)), ByVal VarPtr(p), 4
HookBytes(5) = &HC3
MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0)), 6
Flag = True
Hook = True
Private Function MyDialogBoxParam(ByVal hInstance As LongPtr, _
ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, _
ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer
If pTemplateName = 4070 Then
MyDialogBoxParam = 1
MyDialogBoxParam = DialogBoxParam(hInstance, pTemplateName, _
hWndParent, lpDialogFunc, dwInitParam)
Step 8: Repeat Step 6 and 7 and paste following code in “Module 2”
If Hook Then
MsgBox "VBA Project is unprotected!", vbInformation, "*****"
Step 9: We are almost done. Next you need to run your code. To run the code, click on small Play button on the menu bar on top
You will see a message like this. Click on “OK” and your locked VBA project will be accessible now. Please note: This trick will work on 64 bit MS Excel only.
If we want to share our screen for work or school related presentation, we require a specialized software to share the screen. Most of the organizations and school already have licenced tool available for this purpose. Most of the screen sharing tools requires an advance preparation before you can start. For example, the software must be downloaded, installed, configured and registered before you can actually start using the same. In some organizations, access to these tools are restricted to higher management only.
