Wifi congestion

Most routers use "admin" as the login and "password" as the password. The login details may also be printed on the back of the router or in the instruction manual that came with it. If you cannot access your router, try searching the internet for your individual router's access method.

For my own Telus router, changing the Wi-Fi channel is easy. First, I navigate to the router login address and enter my login and password. I then change the network channel to the option which offers a good connection, save the settings, and restart the router by power cycling it turning it off and on again. Afterward, it stopped randomly disconnecting. One thing to mention is that most modern routers include a feature that combines 2. This feature is notoriously unreliable, and if you're having network problems, I suggest disabling it as a precautionary step.

On my Telus router, it's referred to as SmartSteering. Other brands have completely different names. If your Wi-Fi sucks, using a Wi-Fi analysis app is the best way to find out your router's ideal network settings.

If after changing your router's channel, you're still getting unreliable internet, consider optimizing your network for speed instead. Sometimes ironing out the kinks on your home internet might fix reliability issues. Internet connection too slow? These simple router tweaks could make a world of difference on your home Wi-Fi network. For over 10 years, the 2. However, that success has also been the 2.

The Wi-Fi boom saw a huge shift in technological devices that were able to connect to a wireless network. Most of these devices were connecting to the network on the 2. Microwave ovens, baby monitors, electronic garage doors, and Bluetooth devices are just a few examples of devices that also operate on the 2. This boom in devices resulted in severe congestion on the network. The 2. Well, this is where the techy bit comes in. The channels on the 2. The entire 2. Ultimately fitting this many channels into such small space means that some of the channels end up overlapping with each other.

This is what we call adjacent-channel interference in Wi-Fi. Most households, offices, bars, restaurants and even some cars offer the ability to connect to a wireless network.

The end result is a congested frequency band with limited scalability. We know the 2. For the last ten years, most devices that are Wi-Fi enabled have been solely 2. One of the biggest benefits of 5 GHz is that it provides the foundation for the newest Wi-Fi standard: Another issue related to over-utilized devices that can cause network congestion is Bottlenecks.

As in most hierarchical designs where multiple devices feed into a higher-level device, care must be taken to ensure that the higher-level device is capable of handling all the traffic from the lower-level devices. If this is not the case, then the higher-level device can result in a bottleneck causing congestion on the network. Think about a 4-lane highway merging into a 2-lane road. I once performed a network performance assessment for an organization.

They were buying Mbps link capacity from their ISP but the users on the network were struggling to connect to the Internet effectively. Upon investigation, we discovered that while their ISP was truly giving the agreed upon Mbps, the edge device was only providing 30Mbps to the network! Apart from the fact that this organization had wrongly terminated the link on a FastEthernet interface which gives a theoretical speed of Mbps but much lower practical speed , that interface was also faulty.

By moving the ISP link to another interface we used a GigabitEthernet interface instead , the performance problem was solved. In another organization I consulted for, a network of about 10 users had poor browsing experience even with the 4Mbps link they were getting from their ISP.

Ideally, this capacity should have been enough because the users were not doing anything heavy on the Internet — just emails, web searches, and normal user activities. Other security attacks that can result in network congestion include viruses, worms, and Denial of Service DoS attacks. Feeling the effects of network congestion is one thing but actually confirming that a network is congested is another. In this section, we will look at some activities that can be performed to confirm the congestion of a network.

One of the fastest ways to check if a network is congested is to use Ping because not only can it detect packet loss , it can also reveal delay in a network i. Using a tool like MTR which combines ping and traceroute can also reveal parts of the network where congestion is occurring. A tool like iPerf can be very useful in determining performance issues on a network, measuring statistics like bandwidth, delay, jitter , and packet loss.

In the same way, tools that monitor bandwidth can reveal network congestion especially during a security attack or if a particular host is using up all the bandwidth.
