How do I secure my wifi?

This is my first post here. Recently, My friends and I went through this horrible time period where a guy from our workplace hack our wifi and ultimately hack into our conversations and credentials. After this dilemma, I am very much curious about my wifi security. The problem is that with my increased daily workload I can’t research the solutions. All I want is a basic checklist to check every time and it would be more good If I can have a solution as a product. Which can secure my connection once and for all whether I am at home or not? Do you guys have any idea about this?

Probably this is something for you

There are plenty of guides on the web.

A very strong password that is not written down anywhere publicly reachable is of course the most important step. Checking the first 100 passwords that any brute force bot or software will test probably helps:
Probably the router has some brute force protection to block clients for a certain time that fail to login with wrong password for a certain amount.

All clients that store it to auto connect on boot, must be up to date, so there is no way to e.g. read out the WiFi password by hacking the OS WiFi software.

The router firmware must be up to date with at least WPA2. And a firewall (usually NAT which only allows/forwards specific incoming ports) and things like UPnP or public router login methods must be disabled, so the router itself is only accessible from local network and at best no incoming connections are allowed.

If incoming connections are required, e.g. webserver and such, the related software must stay up to date.

It is really most important to keep things updated, so there are no known security vulnerabilities. And do not write or type the WiFi (or any other access password) on any public place.

Pretty common things, but probably it helps.

Sorry for the late reply. and thank you so much for your detailed guidance :slight_smile: we thoroughly researched and consulted with other It friends. We opted for Heimdal security but it is not budget-friendly. So, we again started looking for an alternative solution then we came to know the economical solution which does not be tech-savvy and light on our pockets. It will secure our home network and devices associated with it. It is working fine till now.

P.s: the service we used is

once again thank you so much for all your guidance.

well using a VPN will not improve security on your local WiFi. It will encrypt the connection for single devices into the internet using the VPN. But, still the local WiFi will be same as before.

And to avoid a misunderstanding, I did not try to do any advertising for Heimdal security. Even, I don’t know what they are selling :slight_smile: Just found it an interesting blog post
