Step 1: On the Modem system administration interface, here with the TP-Link WR845N Modem, navigate to DHCP to reset settings.
Step 2: Here, re-enable DHCP and set it to allow IP usage from 20 to 255 only. This setup helps you reorganize IP addresses, a feature present in all modems. Of course, with more advanced modems, creating rules is much easier.
Step 3: Next, go to the Bandwidth Control section, where you can limit WiFi bandwidth.
Step 4: Here, check the box for Enable Bandwidth Control and adjust the download and upload values as follows:
In the illustration, we set Egress Bandwidth and Ingress Bandwidth to 60,000 Kbps because our network is using 60 Mbps. After conversion, the speed will be 7.5 MB, which will be the speed for all WiFi users before any limitations.
>> Now, click on Add new to set up additional WiFi bandwidth limit rules.
Step 5: Here, simply check Enable to apply it immediately.
In the IP Range section, keep it from 20 to 255 as you set earlier (for 1-19, use your own IP).
For both Egress Bandwidth and Ingress Bandwidth, depending on your choice, set it from 2048 kbps to a maximum of 10240 Kbps, which translates to speeds from 256 Kbps to 1 Mbps, up to 7 times slower than the maximum speed.
Lastly, your final task is to reboot your WiFi modem to revert all settings and configurations back to their original state.
Above is a guide on how to limit WiFi bandwidth applicable to small businesses or home networks. Adjusting bandwidth is the best way to manage your WiFi network effectively. Avoid situations where streaming movies or heavy files hog the network and inconvenience others.
In addition to limiting WiFi bandwidth, changing the WiFi password is also a measure to restrict users, especially your neighbors. To change the WiFi password, we also need to access the system management section as described in the article.
Currently, there are numerous malicious software programs for hacking WiFi on laptops circulating on the internet. However, such software poses many hidden risks that can harm your device. Therefore, readers should refrain from using unauthorized software just to hack WiFi on their laptops.
