Solving Common WiFi Issues Through Professional WiFi Surveys

Tired of dealing with frustrating WiFi problems like slow speeds, dropped connections, and dead zones in the office?

Professional WiFi surveys could be the solution you’ve been looking for. In basic terms, WiFi surveys are comprehensive assessments conducted by trained professionals to identify and address common WiFi issues effectively.

Here are some of the most WiFi common issues and how they can be resolved:

Identifying coverage gaps and dead zones

WiFi surveys offer a thorough look at your WiFi setup, going beyond simply checking signal strength. These surveys meticulously map out how WiFi signals spread throughout your space, revealing areas where signals weaken or disappear entirely, known as dead zones or coverage gaps. This insight can uncover what’s causing these issues—whether it’s thick walls, interference from other devices, or poorly placed access points.

After analysing the survey results, skilled professionals come up with tailored solutions for your specific situation. suggesting where to put access points or signal boosters to fill in coverage gaps and get rid of dead zones. By placing these components strategically, professionals make sure that WiFi signals reach even the trickiest spots in your space, providing reliable coverage and connectivity all around. 

Addressing network congestion

Network congestion is a very common issue, particularly in office environments bustling with multiple connected devices. This can severely hinder WiFi performance, leading to frustratingly slow speeds and unreliable connections. WiFi surveys come to the rescue by delving deep into network traffic patterns, identifying congested areas where bandwidth is stretched thin.

Armed with this information, skilled professionals employ a range of strategies, such as optimising channel assignments and fine-tuning access point configurations and network settings. These adjustments ensure that data flows smoothly and efficiently across your WiFi network, minimising bottlenecks and maximising available bandwidth. With congestion relieved, users can enjoy faster speeds, smoother streaming, and more reliable connections, even in environments with high device density

Minimising interference

Interference from neighbouring WiFi networks and various electronic devices can significantly impact the quality and reliability of your WiFi signal. This can result in slower speeds, dropped connections, and overall degraded performance. WiFi surveys are instrumental in identifying sources of interference and recommending effective solutions.

During a WiFi survey, trained professionals utilise specialised tools to scan for interference sources within your environment, which may include neighbouring WiFi networks operating on the same frequency bands and even non-WiFi devices such as microwave ovens and Bluetooth devices.

One common strategy for minimising interference is adjusting channel frequencies. WiFi networks operate on different channels within the 2.4GHz and 5GHz frequency bands. By selecting channels with less congestion and overlap, professionals can reduce the likelihood of interference from neighbouring networks. Additionally, professionals may recommend relocating WiFi equipment to less congested areas or repositioning antennas to optimise signal strength.

In some cases, advanced techniques such as spectrum analysis may be employed to identify and mitigate sources of non-WiFi interference. This allows professionals to visualise the RF spectrum in your environment, identifying specific frequencies where interference is occurring.

Enhancing security

WiFi surveys also play a crucial role in assessing network security and ensuring compliance with industry standards. Trained professionals conduct a comprehensive evaluation of your WiFi network’s security posture to identify vulnerabilities and weaknesses that could expose your network to unauthorised access or potential threats.

One key aspect of WiFi security assessment involves evaluating encryption protocols. Professionals examine the encryption methods employed by your WiFi network, such as WPA2 or WPA3, to determine their effectiveness in safeguarding data transmission. They assess whether encryption protocols are up-to-date and properly configured to provide robust protection against eavesdropping and data interception.

Access controls are also evaluated during WiFi surveys to ensure that only authorised users can access your network. Professionals review access control mechanisms, such as MAC address filtering and guest network segregation, to verify their effectiveness in limiting network access to authorised devices and users. They may recommend implementing additional access controls or strengthening existing ones to enhance network security.
