Short Bytes: Very often free Wi-Fi comes with time limits and one needs to pay to continue using the internet. But, using methods like MAC address spoofing and DNS Tunneling, one can bypass the time limits. As these methods are a little dishonest, one should only use them when needed urgently.
How to get free Wi-Fi is one of the most searched terms when it comes to network hacks. In my previous article, I’ve explained different ways to grab a free bite of internet using many simple ways.
Out of those methods to get free internet, I talked about coffee shops, restaurants, and hotels that offer free Wi-Fi. But, many employ time limits on them to control how long a customer uses the Wi-Fi. This trick is also used by the business owners to ensure that a person doesn’t spend too much time in their establishment.
How To Bypass Wi-Fi Time Limits?
There are a couple of methods to circumvent this Wi-Fi time limit to continue using the free Wi-Fi. Please note that these methods are a little devious, so employ them only in critical situations.
Mac Address Spoofing:
The solution to this problem is very simple. All you need to do is use an app that can spoof a new MAC address and allow you to keep accessing free Wi-Fi. Even changing a single number should help you out. The MAC address is basically how a particular network recognizes your computer. So, if you change your MAC address, the network will consider you a new computer and reset your timer.
You don’t need to worry about the losing or resetting your real MAC address. It’s embedded into your hardware. So, when you restart your device, you’ll get back to your original MAC address.
To do this, there are tons of free tools like Mac Makeup, SpoofMAC etc. You can also do this manually by changing some network settings.
Another method to bypass Wi-Fi time limits is to use DNS Tunneling. This method is usually employed to get free internet access at places where you need to pay for the Wi-Fi. However, this method also works if you wish to continue using the free Wi-Fi for a longer period of time.
The coffee shops, hotels, and airports that provide free Wi-Fi, reroute all HTTP requests to their web page until you pay for access or log in using your credentials. But, they don’t reroute DNS requests. So, if you use the free Wi-Fi using a remote DNS server with some specialized software, you can enjoy unlimited internet.
Sniff other device’s Wi-Fi MAC address:
Another method is to use your Wi-Fi and sniff other devices’ Wi-Fi MAC address. Once you find a person (or employee) who has a permanent login access, you can use tools like InSSIDer, NetStumbler, Cain and Abel etc. to copy the MAC address.
Go buy another cup of coffee!
As I mentioned above, some of these methods are unethical and one should avoid using them. So, if you are feeling like staying for another hour, just buy another cup of coffee 😉
But, is public Wi-Fi safe?
If you’re in a renowned cafe or restaurant, there are changes that you’re safe and the owner won’t indulge is some fishy activities. But, you never know. Hacking the devices using public Wi-Fi is a common attack mechanism. So, use of a VPN is advised. You can read our article on the benefits of using a VPN. Just in case you’re wondering about some good suggestions, Private Internet Access VPN, ExpressVPN, and IPVanish are good options.
