Most people are relatively satisfied with their internet connection in the beginning & then the usual problems start to come up like slower speeds than promised, breaks in connectivity, downtime, certain websites taking longer to load than they usually do etc. Here’s how you can stay on top of your broadband internet & maximize your best High Speed Internet Speed.

Power Cycling or Hard Rebooting (Commonly known as Rebooting) your home Wi-Fi router can fix Internet connection, improve slow connections and resolve wireless issues.

How to Power Cycle / Hard reboot your Wi-Fi Router:

1. Switch-Off Power Supply to Wi-Fi router .Verify you have Switched-off correct supply by checking that all the lights on Wi-Fi router are turned OFF.

2. Wait 1 minute.

3. Switch-ON Power supply to Wi-Fi router. Some Lights should be back-ON on the Router. Wait for the Internet light to turn green.

4. Try connecting to the Internet.

Please DO NOT push reset button on the back of your modem as doing so will necessitate a reconfiguration of your WI-FI router.

Below are common problems which are resolved by rebooting your Wi-Fi router .

Too many Connections

Your router's hardware (CPU, RAM, 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 performance of your existing connected devices. It can seriously slow down internet speeds on all your connections.

Try reducing number of connected devices on the Wi-Fi router

Sometimes, even single device may generate many TCP/UDP connections. This is especially common if you are using file-sharing applications such as BitTorrent and Usenet, which achieve high download speeds by making multiple connections at one time. Most routers keep TCP connections alive for 3600 sec or more (especially d-link one), so each time you establish a connection on a BitTorrent client, your router open a new TCP Connection. After a few hours, maybe a day, it can become a problem very quickly as you might imagine.

Just shut off your Torrent/file sharing/Usenet client for a few days and see if your problem reduces. If so, you've found the problem and you'll just have to tune your Torrent/File sharing/Usenet client Application for a lesser number of Connections/Seeds, Limiting download speeds, limit upload speeds depending on what your client application allows.

Experiment with settings till you have the right balance between file sharing application speeds and router reboot.

Sometimes, this may also happen due to malware/virus on Wi-Fi connected devices. Try running a good antivirus, do a full scan. 

Wi-Fi Channel Configuration

Wi-Fi protocol allows 13 channels in 2.4GHz band. However many Laptops /Mobiles do not support channel 12 & 13. This is because many countries do not allow Chl. 12 & 13 by regulation. If your Wi-Fi router has auto selected chl. 12 or 13, some of devices may not work. Rebooting the router helps if it selects another (1-11) channel.

You can change the channel setting such that it selects between 1 -11 or you can fix Channel setting on any channel between 1- 11.

Also for similar reasons, keep Chanel width at 20 MHz even when you are allowing 802.11N. This is because some phones may not work correctly on 20+20MHz settings.

Router Installation & Placement 

While you can place your Wi-Fi router at any place in your home, here are few pointers to get best coverage.

  1. Do not install near to the Window. External interference will kill capacity. And half of radio energy will be out of Window.
  2. Install where it is open, at least, on three sides. A wall on one side will act as good reflector.
  3. A brick /stone/masonry wall will kill coverage completely in blocked direction.
  4. A wooden/Glass window/door/partition will reduce coverage by half in blocked direction.
  5. Install at least 3 ft. above the ground, above the furniture line. Higher the better.

Estimating Coverage 

Think of your Wi-Fi router as a 100 W light bulb. Imagine if a light bulb is kept at the place in your home where you want to install your home Wi-Fi router. Your coverage would be similar to where the light can reach in an otherwise dark home. Light intensity would signify signal strength. 

Typically a home Wi-Fi router can cover 1000-1200 sq-ft. area. 

For larger houses, you can use multiple Wi-Fi routers connected thru LAN cables. Do not use wireless Range extenders /Repeaters. They reduce Capacity and increase latency. 

If you do not have LAN cables across rooms, you can use Home Plug AV2 with Wi-Fi which uses your Electricity wiring to connect multiple routers in home. Configure same SSID (Network Name) across the routers so you can roam inside your home. Keep LAN IP address range exclusive. 

Configuring a Router 

It is fairly straightforward for typical home installation. You need to connect your PC/Laptop to a LAN Port with a Cat5 Cable. Open your browser & give default IP address (written in Manual), Admin user & password. Configure your router with help from the User Manual.
