There are many reasons for WiFi Slowing, but in some cases you can  improve the performance easily, follow these instructions to have an optimum WiFi network:

1- Find a Good Place For Your Router

Not all places are equally suitable for your router. Avoid placing your router close to metal objects and appliances that propagate electromagnetic waves. Metal is the top disrupter of a WiFi signal, and its presence close to a WiFi router can cause the “Reflection phenomena” and  badly effect on your overall WiFi performance.Generally, all household appliances propagate electromagnetic waves called “environmental-noises”, microwave oven, cordless phone, fluorescent light-bulbs, circuit breakers, and electric razors are the biggest emitters of electromagnetic waves. Make sure you are placing a WiFi router in as central-top a location in your house or apartment as possible. WiFi signals radiate in all directions, not just horizontally. It’s better to place your router near the ceiling.

2- Update The Router’s Firmware

The large number of malware attacks that are costing businesses and individuals every year is growing so fast. Many of these attacks wouldn’t be possible if all routers were kept updated. The malwares can steal bandwidth of your router and spread itself across the network to other devices. Consider in mind, even without presence of a dangerous malware, routers with old firmware perform worse than routers that are properly updated.

3- Change The Router’s Antenna

Most WiFi routers come with weak antennas, you can change them with most power full antennas to have a better WiFi coverage. Most routers have 2dbi to 4dbi antennas ( the antenna gain is measured in dbi). You can find antennas up to 10dbi in the market , which makes your WiFi coverage 2-3 times greater.(theatrically , each 3dbi antenna gain, doubles your WiFi coverage). There are several different types of WiFi antennas, but the most common one for indoor WiFi routers is “rubber duck” or “ Omni” antenna. You can simply open your existing antenna and replace with the new one. BUT the only point you should consider, is the antenna’s connector. Before buying an antenna, make sure the connectors types are the same (most common antenna connector is RP-SMA-male or female).

4- Check The Interference

Your neighbor’s routers may be interfering with yours and causing the signal to degrade. Wireless routers operate on a number of different channels (3 non-overlapping channels in 2.4Ghz and 23 non-overlapping channels in 5Ghz), you should find most clear channel for your router.to find the most clean channel , you can use WiFi analyzer tools .

5- What’s Your Router’s Band?

Generally , we have 2 Bands in WiFi technology, the 2.4Ghz and 5Ghz bands. The 2.4GHz band According to the laws of physics , has a better coverage and penetration in walls and other structures , but  it doesn’t offer  a reasonable bandwidth .In the opposite point, the 5GHz band , offers a better bandwidth , but with the least coverage and penetration level. You can find out whether your router is a dual-Band router and supports the 5Ghz band or not .if yes, it’s better to change your router’s band to 5Ghz band if possible.

6- Check The Channel-Width

Based on your router’s and clients’ technology and standards, you can have 20Mhz/40Mhz/80Mhz channel width. With the wider channel, you can achieve more bandwidth as well. But consider in mind, you should choose proper channel width based on the interference level(Wi-Fi interference is any signal outside of your Wi-Fi network that overlap your Wi-Fi channel).it means if you have a clean environment you can choose wider channel and if you have a noisy environment , you will limit to choose a narrow channel-width. Generally , you can choose 20Mhz channel-width in 2.4Ghz band  and 20/40/80 Mhz channel-width in 5Ghz band.

7- Check The Signal Level Everywhere

In advanced routers, you are able to set the router’s output power(TX Power) between 17 and 25 dbm ( the wireless output power is measured in dbm) depending on the extent of your home and the existing obstacles and walls. This value should be adjusted carefully so that you have  a RSSI around -65dbm. (RSSI means the received signal level at a certain point, this number can be between -30dbm and -85dbm, and you can measure the RSSI at a certain location by WiFi analyzer tools like : “WiFi Analyzer” for android , “OpenSignal “for IOS , and “InSSIDer” for windows) . Keep in mind that increasing the router’s output power may cause users to lose quality in communication, so try to choose the right amount for this option and avoid unnecessarily increasing it.

8- Control Bandwidth-hungry Clients By QOS

Bandwidth-hungry application or a client to make download and upload huge files or videos, can degrade other users communication’s quality . Modern routers support services like QoS (Quality of Service), which allows you to prioritize certain applications over others. With QoS, you can dedicate a specific amount of overall internet bandwidth to specific service or client, for example , you can dedicate 30% of overall internet bandwidth to your online gaming system , to be sure it won’t ever be interrupted by a person watching a high quality video on YouTube or downloading a huge file from the Internet.
