lets do 1 answer for one of many ways a fire wall works that is WAN to LAN. that means from the internet to you PC at home. your WAN ISP port is 100% locked out. If fact mine here can not be even pinged. I'm 100% safe here.
Seen both in the ROUTER and again in the OS you run. you have 2 fire walls for sure.
NO OS told but W10 has this too. control panel firewall look. there is also Lan to lan, lan to wan firewalls. Think of a firewall as huge digital filter, that is what it is. from simple to complex.

I suggest you boot your computer into 'Safe Mode with Networking". This can be done by: -rebooting computer or turning it on if it is currently off -when you see the bios screen begin tapping 'F8' -this should eventually bring up a black screen with white text -choose Safe Mode with Networking
While in safe mode you should now download the free version of MalwareBytes.
Install and allow it to update. Now run a full scan and have it fix
any problems that it finds. Reboot your computer and hopefully
everything is back to normal.
If this doesn't work you may have to back up all your
personal files to another drive and restore/reinstall the operating
system.
Hope this is helpful. Let me know if you have any questions or need any further help

ok you got to send more info or chat with but this may help go to your system setting on your computer which would be control panel look for the type of firewall settings and you'll need to manually set them to the type of sites you want open.
In the field of networking you can try doing a Phd in Wireless security...
Right now there are about 3 types of wireless security, but only one type is compatible with all operating systems... But that kind of security is not more secure.... Other types of security that are more secure are not compatible with certain wireless cards...
Why dont you do a research in that...????
Any further help, comment back....
You can try connecting to wireless in Safemode with Netwroking. Boot the computer is Safemode with Networking and search for wireless networks, if able to connect in Safemode with Networking then surely the issue is with security program
CHECK THESE THINGS IN THE CONTROLL PANEL, DEVICE MANAGER, NETWORKING AND SHARING, PROBLEMS AND REPORTS, SECURITY, WINDOWS SECURITY, WINDOWS FIREWALL.
NOT DOING THESE CHECKS IN THIS ORDER WILL BE A PAINFUL PROBLEM, CHECKING EVERYONE OF THESE AREAS, YOU WANT ALL GREEN MARKS, ************* NO

To setup security on your desktop computer, you basicly need
antivirus software
firewall software
antispyware software
http://www.avast.com/ (antivirus take the home, its free 14months registeration is free, free for home use, after 14months you can register again, free of charge, I have used this software for few years)
Spybot antispyware software http://www.safer-networking.org/index2.html you need to run this program 1-4 times a month to keep your pc clean. it doesn't work on the background like the firewall and antivirus.
that is a complex topic, for sure.
it is LAN and WAN security device.
