WAMP is not responding to external requests - php

Question

Installed WAMPServer
Version : 3.0.4
OS type : 64 bit
Apache : 2.4.18
PHP : 5.6.19 / 7.0.4 (5.6.19 checked)
MySQL : 5.7.11
I've tried to look at the older overflow questions and answers and tried to do along as they said, however, I still do not have any connection to the wampserver.
What I've done to test
Use localhost on the host laptop to check if wampserver is operational
[SUCCESS]
Use my IP on host to check if wampserver is operational [SUCCESS]
Use my IP on other devices on the network in attempt to access a php file of the server in a directory. [FAILED]
Use other devices to on the network to ping my host [Request timed out x4]
Use tracert command as an alternative to 4 [Request timed out]
What I've done to the server
Modification to httpd.conf
Listen 12.34.56.78:80//commented
Listen 0.0.0.0:80
Listen [::0]:80
Dynamic Shared Object (DSO) Support//commented
miscellaneous for LOAD MODULE
ServerName localhost:80

What I've done to the host laptop
Fresh installation of WAMP
Backup original httpd.conf
Edited httpd.conf (Refer above)
[FAILED]Added rule for port 80 to enable all - Deleted
Disable all rules for inbound for port 80
Look for rules in outbound for port 80 [NONE]
All of the steps I've described does not work at all. Has no experience in firewall configuration and WAMP configuration. And no virtual hosts except localhost
P/S: The example link I tried testing was 1.1.1.1/testPHP/testPHP.php. The host is Win10 while the device on the similar network tested was XP. Any advice is greatly appreciated.

Answer 1

The apache configuration seems correct.
Check this if you're using Wifi on server or client
Check if the router/AP has enabled something called Wifi Isolation, or Client Isolation.
I looked on a similar router like yours and there it's one option called Client Isolation on the Wireless Basic setup of your router. Uncheck it, save and retry.
Check this on the Windows firewall
Press on your keyboard WindowsKey+R, write control.exe. Press enter
Double click on Windows Firewall
On the left vertical bar select Advanced Settings
Click Inbound Rules
On the right pane click New Rule...
Select Port and click Next button
On the top leave TCP option selected. And below select Specific local ports and write there 80 or the port your apache uses. Looking to your Listen line on the apache config you should write here 80. Press Next
Leave selected Allow the connection and press Next.
Select the profiles of the Firewall you want to use for this rule. If you doubt select all. Press Next
Set a name for the rule, and press Finish
Try it another time ;-)

Answer 2

Found the problem. Win 10 apparently had this setting I have had forgotten about - Make this PC discoverable (OFF)
I turned it off in the heydays of using Win 10 because of privacy concerns. Now it can be accessed. The next step is to figure out the forbidden access.
Edit
The culprit for this post is the Windows 10 OS Settings. In order for all the settings to work (Assuming the person has done all the tinkering with httpd.conf and firewall and/or router), the PC hosting the server must be checked whether is the PC discoverable in the network settings.
How to make sure it is discovered
Open Network Settings by left clicking the network icon on your taskbar (either lan or WiFi) then click Network Settings right above the bottom most icons.
Select Advanced Settings
Under the item Make this PC discoverable, there will be a switch button. Make sure the button is turned ON otherwise, left click on that particular button.
