In principle, all you need for trouble-free Wifi connections is a shiny new router in your home or small office. Yet in practice, issues with interference still haunt the wireless reception
Interference may cause slow transmission, higher latency than hardwired connections, frequent disconnections and reconnections, and often a complete failure to access a WiFi signal. It can be not easy to solve. The answer isn’t as easy as changing routers unless you are fortunate.
Your goal is twofold: 1) You want to avoid paying for hardwired Internet connections in your home or workplace to circumvent weak or unreliable wireless connectivity; 2) You want to avoid purchasing more costly wireless routers which could still be prone to interference.
Your home or office WiFi network uses radio signals to spread Internet bandwidth in the same technology used for FM radio, smartphones and rabbit-ears on television. It’s prone to the same kinds of issues — intrusion, blocks of penetration and limitations of range.
You may usually attribute wireless communication issues to a shortlist of culprits: signal interference, router location, software problems, hardware failures, and the physical size of your home or workplace.
Your neighbours may also be responsible for your WiFi issues, though. WiFi signals and noise from nearby electric supplies are one of the most common causes of WiFi interference. Is where the image of your neighbours comes in.
To fine-tune your WiFi system, use the tips below.
Survey the area
If you have wireless issues, first make sure your service provider or ISP’s hardwired link isn’t at fault. Some providers offer the Internet cable modem as a part of the WiFi service.
By calling your ISP, you can check that the hardwired Internet connection to your home is working correctly. The technician can conduct line tests remotely, reset your link, and get you to run speed tests with a hardwired laptop to the modem. The technician may schedule a service call to your property to fix the problem when he finds a problem.
Skip the ISP diagnosis and concentrate on troubleshooting to fix router issues if your wireless access comes solely from a handheld WiFi system. In this situation, you aim to protect your mobile WiFi system from the intrusion and penetration factors.
Conduct an enquiry to identify possible culprits. Through trial and error, rule out any of these items:
The web counts. Is your router stashed at a remote corner of your office or workspace? Was this down to the floor or does furniture cover it? Drag it to a higher level—the more excellent the sight-line, the greater the connection. Try to place your router as near as possible to the middle of your house.
Unplug the modem or router into your computer. Then turn off the monitor and shut off all other networked equipment, like any media-streaming gadgets. Reboot your modem and let it power on fully. Then, if you have one, switch on the additional router and wait for the lights to stabilise. Finally, power and link it to the wireless signal on your device.
Conduct an Internet search for the speed check page of your ISP, or use a tool for speed testing by third parties. If the hardwired link gets terrible results, please contact your ISP. A weak wired connection produces enormous wireless feed. Through default, WiFi links are slower. Upload speeds are getting higher than upload speeds.
It’s time to extend your on-site survey if you find that your wireless tests are much too late, or differ dramatically with each check you run. Begin searching for nearby devices that may cause signal interference in your home or workplace.
Routers also interact with devices widely used, such as cordless phones, Bluetooth speakers, microwave ovens and baby monitor. All these devices temporarily switched off and WiFi link verified. Turn one by one on each computer to locate the suspect. Moving the wireless router elsewhere will mitigate the interference, or remove it.
Other sections of your home or office can notice the reception falls off. That points to a question of penetration or selection or both. In this case, extend the survey to areas where there is low signal power.
Download your smartphone with WiFi-analyzing software. A decent option for Android is Farproc ‘s WiFi Analyzer, which has a signal intensity meter in real-time. There are other features, too. You can get the free download from the Google Play store at Farproc.
You are using a free tool such as WiFi Heatmap, a network analyzer and signal meter available at Google Play, creating an interactive WiFi heat map of your location. Netspot operates for Macs and computers running Windows. You can also use an app like the free Android WiFi Analyzer, which has a power meter for the real-time signal.
Another reliable choice is Network Analyzer, an all-in-one iPhone and Android app that analyzes networks, tests and identifies issues.
Commonly used connected home devices use a block of 2.4 GHz tiny-wave frequencies that have problems penetrating solid, mass-like walls. The 2.4 GHz frequencies, known as “channels,” are widely used by adjacent WiFi networks, and thus may cause interference.
WiFi standards break WiFi signals into up to 14 overlapping channels in the 2.4 GHz region, which serve as a range of frequencies. The channels designed to work together, but they may interfere with each other when two or more neighbouring networks use the same channel, reducing bandwidth.
You can turn the WiFi channel of your network to one that is not being the used close.
Open the dashboard for the router setup from a Desktop browser which connected to your router. For instructions and password, please refer to the router manual. Carry out a Web-based search for a copy based on the model number if you need it.
Then open the wireless tab on the router. Select an unused channel which is usable. Save setup, and test the results of the connection.
When you live or work in an apartment or condo-style home, it can be beneficial. If you have a nearby WiFi network running on the same channel as your network, change yours.
Household devices, including cordless phones, baby monitors, and microwave ovens, can cause wireless interference. Once they are in use, your WiFi network may drop out. This condition is one of the critical causes of so-called “intermittent interference.” It could take some clever sleuthing to track down the offending device or devices.
May happen when a computer uses the same channel. Co-channel interference may also result if access points located too close together or if they equipped with too high output capacity.
A simple way for other WiFi equipment to minimize or remove interference is to allow auto-channel if it enabled on your devices. The WiFi access points which use auto-channel scans the WiFi spectrum periodically and selects the most transparent channel based on what other WiFi signals available.
The choice is to purchase and use cordless phones and headsets not using the 2.4 or 5GHz frequency. Current cordless phone systems are using DECT 6.0 technology and the 1.9GHz band, not bands of 2.4GHz or 5.8GHz.
The same repair could work with a baby monitor or other video surveillance tools. Most baby monitors, for example, run at 900MHz, and do not conflict with WiFi. Most wireless displays, however, are 2.4GHz which may conflict with 802.11 g or 802.11n single-band routers.
Penetration — or lack of it — is a real situation that should be taken into account when your WiFi signal does not hit devices in other rooms in your home. It’s similar to range problems, but physical barriers may hinder even routers with the potential to go the distance in your home or office.
Do not place the router, for example, near reflective surfaces such as glass, mirrors, and metal. WiFi signals are more likely to bounce off. Walls can significantly degrade your WiFi signal, especially those made from concrete.
All metal surfaces mimic WiFi signals. Signals can bounce off walls, mirrors, metal file cabinets and countertops in stainless steel, decreasing the range and efficiency of both the network.
Water — consider the fish ponds and the water lines behind the walls — will absorb WiFi signals, reducing the signal intensity drastically. Substantial interference will come from nearby TVs, Halogen lamps and switches to the electric dimmer. Interference induced by stereo or computer speakers. So you can place a router in a wall, close to power lines.
One helpful alternative to alleviate these situations is to mount a set of WiFi Extenders rather than switching the router or mobile device. Such small gadgets are plugged into a wall socket, combined with the router, and have broader WiFi signal coverage.
Buy New Gear
There are two other methods for reliably curing weak WiFi. Just upgrade the firmware of an older router, or purchase a new router.
Old firmware also bears the blame. Holding your firmware up to date will mitigate or remove outright ongoing connection issues.
You may need to access the administrative interface of the router through a web browser to update the firmware to older devices. Newer routers allow you to upgrade your computer by pressing a button.
Often, just getting a new router is the best cure. The new models offer faster WiFi speeds, better coverage and better range.
Look for a router with a dual- or triple-band capability with 802.11 N or AC technology. AC routers have a maximum spectral bandwidth of around 8 x 160 MHz, compared to the N routers range of 4 x 40 MHz. The increased bandwidth allows for the transfer of more data without slowing down.
Find a multi-band Router. This solution will allow you to keep older 2.4GHz devices on their bands while allocating new devices to the higher bands which support the latest WiFi standards. Essentially, it lets you run as if you had several routers.
One of the recent enhancements to the WiFi network is a Mesh network. This system is much more expensive than installing WiFi Extenders, but in hard-core reception circumstances, you may find it appropriate. Mesh routers configured to distribute coverage over multiple access points of a WiFi network.
