Speed Test shows Low Internet speed?
If you want to check Broadband speed from the Internet Service provider, Connect your Laptop/Desktop to Wi-Fi router LAN port with LAN cable and conduct speed test on netspeed.tikona.in. Ensure there is no background process running on the Laptop & other Laptop/TV/mobile devices are not connecting on to the Wi-Fi Router on Ethernet or Wireless.
Caution: Connectivity provided by your Internet Service Provider should always be connected to WAN port, which is differently coloured. Do not disturb this connectivity.
Test conducted on mobile devices using Wi-Fi may not show available broadband speed due to limitations described below.
How to improve Wi-Fi coverage?
1. Try moving closer: Wi-Fi Signal is fickle and few meters is too Far in Wi-Fi world. Come closer to Wi-Fi router and check again.
2. Change Wi-Fi router Location: Wi-Fi signals can be absorbed or blocked by various obstruction like Walls, Doors, and Furniture & Home Appliances. Metal cabinet & concrete walls are top disrupter of a Wi-Fi signal and can easily create a large dead zone behind the obstruction. Move Wi-Fi router location high enough and at central point in your home where you can physically see your router from most part of your home. Remember: Do not keep Wi-Fi router near window or Balcony to protect against external Wi-Fi interference & rain water splashes.
3. Install additional Wi-Fi router: You can install additional Wi-Fi router in locations far from your Wi-Fi router and connect new Wi-Fi router to main router on Ethernet cable. Ensure non-conflicting IP address range.
Range Extender/Booster/Extenders also extends coverage at expense of Speed as they share the spectrum.
How to improve Wi-Fi Speeds?
If your Wi-Fi speeds are limited by Wi-Fi routers despite good coverage, you can try following:
1. Reboot: The timeless IT advice, “If it doesn’t work, try switching it on and off", also applies to Wi-Fi routers. A simple reboot (Switch off Power, wait 30 Seconds and Switch on Power again, wait for 2 Minutes) is often enough to considerably improve your Wi-Fi speeds. A reboot clears the router’s memory and allows updates to install. It also resets WAN & LAN ports, removes Stuck beacons and reconnects to Network.
2. Move Media streaming devices to Ethernet Cable: Smart TV or STB running streaming services consume continuous high bandwidth when in use. The use of Wi-Fi may lower down experience on other devices. Connect on Ethernet or Keep them close to Wi-Fi router. You can also consider upgrading to dual-band Wi-Fi router and connect your Streaming devices on 5GHz connectivity.
3. Stop Background Usage: Disconnect other devices to stop background usage. Some bandwidth-heavy activities, like when your computer/mobile automatically syncs files or updates software can hog on the bandwidth and pulls down Wi-Fi experience.
4. Too many Connections: Your router's hardware (CPU, RAM, and Chipset) may not be able to support too many TCP/UDP connections from connected devices. How many? Depends on your hardware. Too many connections just eat up CPU Cycles & RAM space thus denying new connections and lowering the performance of your existing connected devices. It can seriously slow down internet speeds on all your connections. Try reducing the number of connected devices on the Wi-Fi router. Sometime, even a single device may generate many TCP/UDP connections. This is especially common if you are using file-sharing /Peer-to-peer applications.
5. Use Laptop/Desktop instead of Mobile phones for a better experience. Mobile devices do not have very good Antenna for signal reception and speeds on 11n routers may be limited to 30-40 Mbps.
6. Change Wi-Fi Channel: Wi-Fi networks can also interfere with one another, a problem that’s especially common in apartment buildings and other densely populated areas. You can change Wi-Fi channel on your Wi-Fi router to a better channel. You can use a mobile App to scan Wi-Fi signals and select the least congested channel. For the same reason, do not keep Wi-Fi router near the window or Balcony as external interference is stronger here.
7. Switch to Dual Band Routers: If you have 11N 2.4GHz router (300 Mbps), Consider upgrading to Dual Band router. Dual band router have 5GHz band giving faster throughput on compatible devices but provides lesser range and signal penetration. Look for Router supporting Beam-forming to get better coverage on 5GHz.
Why my device is not connecting to Wi-Fi/Internet?
Ensure you are in coverage of your Wi-Fi router and connecting to correct Network Name.
Check Cabling: Ensure Internet Service provider cable is connected on WAN port (Normally coloured differently) and Service provider Modem and Wi-Fi router is Powered-on.
Reboot Modem & Wi-Fi router: Reboot (Switch off Power, wait 30 Seconds and Switch on Power again, wait for 2 Minutes) both Wi-Fi router and Service Provider Modem supply.
Connect your Laptop/Desktop to Wi-Fi router LAN port with LAN cable .If this resolves the problem, you may have to check Wi-Fi router configuration. Follow Wi-Fi router manual to login and setup Wi-Fi router correctly. Some common configuration settings to re-verify following:
• Operation Mode: Wireless Router
• WAN Connection Type: Dynamic IP /DHCP
• Wireless Security: WPA2-PSK
• Verify Wireless Network Name & Wireless Password
Why Wireless Router Speeds and Broadband Speeds different?
Wi-Fi routers are commonly labelled with Aggregate wireless speeds, however, broadband speeds you can measure on your device while connecting to the Wi-Fi router can be far lower, limited by your device (see below table) and broadband speed.
Will increasing Transmit power on Wi-Fi router improve coverage?
No. Wi-Fi coverage are limited by transmit power of your Mobile/Laptop. Thus increasing Transmit power on Wi-Fi router will not improve coverage. In fact, you may experience unreliable connection as signals from your device will not reach Wi-Fi router reliably even though your device will sense a good Signal. Higher transmit power will also cause more interference to other Wi-Fi routers and devices.
Why 5 GHz band coverage is unreliable?
5GHz band provides faster throughput on 11AC compatible devices but provides lesser range and signal penetration. The reduction of the coverage area in the 5 GHz range is particularly noticeable when the router is used in apartment buildings or multi-room offices.
Adjusting the placement and orientation of the wireless router may improve 5GHz signal strength. The best connection to a 5 GHz Wi-Fi is provided in the line of sight (within one room), with a minimum obstacles in the signal path.
High end Wi-Fi routers with Beam forming technology delivers better coverage on 5GHz.
Why Broadband Speed Drop when I close doors especially on 5 GHz
A solid wood door reduces the signal level by about one and a half times stronger in the 5 GHz range than in the 2.4 GHz range. This reduces coverage and throughput.
Even with 40MHz channel on 2.4GHz, Mobile device Throughput is low
Using 40MHz channel on 2.4GHz does not necessarily improve throughput on Mobile devices. In fact, Using 40 MHz channels in the 2.4 GHz band can cause performance and reliability issues on Mobile phones.
Wi-Fi-certified N routers and access points are required to comply with the "Coexistence Requirement" set forth by Wi-Fi Alliance when operating in dense areas with multiple wireless networks, The Coexistence Requirement ensures that the N devices operating in the 2.4 GHz frequency band default to 20 MHz operation when operating in close proximity to other Wi-Fi networks. Read more details here .
Another possible reason that you are not getting the max speed is that you are using a wireless device that does not support channel bonding. Devices such as iPad, iPhone, MacBook, iMac and some Intel wireless devices do not support channel bonding thus will not be able to connect at 40MHz when connected to the 2.4GHz band. In fact, most mobile phone defaults to 20MHz even though the Wi-Fi router is set to 40 MHz
Not all client devices support 40 MHz channels, so don't enable 40 MHz-only mode. Devices that support only 20 MHz channels can't connect to a Wi-Fi router in 40 MHz-only mode. Hence, on mobile phones on 802.11n Wi-Fi, you should configure 20 MHz/40MHz Channel.
Speed test on Mobile Phones with 802.11n router will not show speeds higher than ~30 Mbps, even if your Internet service supports more Speeds.
Should I buy Extender/Booster/repeater to improve coverage?
For good coverage in large homes, we recommend using two Wi-Fi routers connecting over Ethernet Cable instead of Extender/booster. Extender/Booster/repeater extends coverage but consume the same spectrum thus causing interference. This lowers experience of Wi-Fi devices.
If laying cables between Wi-Fi routers is not possible in the Home, then you can go for Extender/Booster/repeater and optimise on coverage & speeds by good placement.
Which Router/Model Should I Buy?
You can buy Wi-Fi router model from a reputed manufacturer based on your need & budget. We have tested various models from Top Wi-Fi router manufacturers, such as D-Link, TP-Link , Mercusys and Netgear.
Caution: Do not buy Wi-Fi router from unknown manufacturer. They could have security vulnerability or malware and compromise your home devices.
Ensure that the Wi-Fi router is not for MTNL/BSNL use as they are ADSL based router. You need a Broadband Router with an Ethernet WAN port.
For typical home usage, 300 Mbps 802.11N Broadband Wi-Fi router would suffice.
If you have Broadband connection exceeding 50 Mbps, are an avid gamer or use heavy streaming services, you can go for Dual Band Router (700 Mbps+). Look for Router supporting Beam-forming to get better coverage on 5GHz.
