Re: how to improve on Wireless Range

This problem is widespread and posted solutions are not getting to the root of it. Yes rebooting the router works - tilll it happens again.  No its not about signal strength etc. Its about how the router handles traffic. complex heavy data flows seem to be a trigger as do certain websites. ( I avoid BBC, google maps etc). No manufacturer wants to address it and no post has given any idea how to preventit.

Re: how to improve on Wireless Range

Wireless and Antenna Terms Wireless routers, access points, and adapters send and receive radio wave signals through antennas. The antenna is hidden inside adapters, but on routers and access points there's a visible antenna. Radio waves can be focussed like a lightbulb. And like a light, some materials reduce or stop radio waves. While light focused from several lights is brighter and makes it easier to see, several antennas in the same area cause interference ? the radio signals will be muddy and confused. Your goals in optimizing power are: * Avoid obstacles. * Avoid interference. * Increase signal strength. Power affects how far an antenna radiates. * Use the equipment in places it's most powerful and most sensitive. Antennas don't radiate equally in every direction. Just as the base of a lightbulb blocks light, and just as a light can be focussed by a reflector, so an antenna signal may be blocked and focused. Since people cannot see radio waves, you'll rely on testing and trial-and-error to get an idea of where antennas "shine" most brightly. An adapter's antenna is important, but the most powerful and sensitive antennas are on routers, access points, and detachable external antennas. The focus of an antenna is either omni-directional antenna or directional. "Omnis" are used in most home products, they radiate horizontally all around, but are weaker upward or downward. When visible, these antennas are usually a rod a few inches long. A directional antenna radiates strongly in a limited direction. It is a flat panel or a dish. These are used for point-to-point transmissions (where two antennas are focused directly at each another). These need a line of sight between them, and preferably a large open space around the main beam. When you are near antennas you'll still get a signal, even if you are out of the direction of its strongest signals. But when further away, you have to be in the direction the beam is the most powerful and unobstructed to receive it. One final concept before you go to the above links is interference. Interference is a signal ? one you don't want ? at the same frequency as the one you're using. Interference comes from devices such as microwave ovens, cell phones, 2.4 GHz cordless phones, and copy machines. Interference is also caused when your own wireless signals are bounced off reflecting objects. Objects may partly or completely absorb signals, reflect them, bend them, or let them pass right through. Metal and water (including the water in people!) absorb or reflect signals. Air, wood, and glass tend to let signals pass with weakening. And when outdoors, plants and the weather may cause interference.

Getting the most out of a Home Network

A wired connection is still the best way to get maximum download and upload speeds because your computer is directly connected to your gateway/router via an Ethernet cable. While this method offers consistent speed, it might not be convenient running multiple PCs and Laptops with a wire in your home.

Improving your wireless connections:

1. Do not use wireless connections where it is not needed or not important.
Devices that are not moved frequently such as a printer or a desktop PC can use the ethernet cable to minimize traffic in the wireless connection. Some home users use a wireless adapter for their desktop PC to connect wirelessly which I think is irrelevant not unless your desktop PC is really far from the router. Most routers provide 4 ethernet ports which you can use for the printer and desktop PC.

2. Make sure that your Wireless Network has WEP/WPA enabled.
All routers are equipped with security features that can provide passwords to your network. A secure network is less susceptible to unathorized use of your network. The more users use your network, the slower it becomes.

Sample video on how to secure your network using a LinkSys Router:

3. Get a better range.
Depending on how your home is designed, your wireless gateway may not be able to reach certain parts of the home, but you may be able to improve access to those trouble spots. There are several companies that have developed wireless repeaters (sometimes called a signal booster), devices that can pick up the signal from your router and extend that signal to other parts of the house. It should be noted that any repeater has its own limitations and the greater your distance from the repeater the weaker your signal and the slower your speed will be.

4. Change your wireless channel to reduce interference.
You may experience weak or dropped signals if a cordless phone or any other electronic device and your wireless router share the same frequency channel. A potential fix for this issue is to change the channel, thereby reducing frequency interference. The wireless channel can be can be accessed in the wireless settings of your routers interface. Channels to choose from are Channels 1 to 11. This should be done in a trial and error method, choose whatever channel delivers the most speed.

Sample video on how to change the wireless channel on a Zoom Router:

5. Make sure that you are running the latest firmware and driver updates.
One of the easiest steps to improve your connection speed is to make sure you are running the latest software updates for your wireless adapter. If you are, the next step would be to check if your network card has been updated with the latest drivers. To confirm that you have the latest drivers available, go to the wireless card manufacturer's website and look for a Support and/or Driver link. If you have a built in wireless client (one that cannot be removed from your PC), check to see if your PC manufacturer has issued any updates.

The above tips has greatly improved our home network which consists of a Prolink router, 2 netbooks, 1 laptop, 1 desktop pc, 1 printer and an occasional use of mobile phones to connect to the internet.

Have a great day!

I am having a problem with a netgear wireless router (WPN824v2), and getting no help from them as the product is refurbished. It is kicking offline, and interfering with my phone (Clear Choice phone...

Improving Wireless Range: Tuning Equipment

Using the best channels has a big effect on network performance. Your goal is to choose settings that avoid interference from other networking and radio frequency equipment. (If you have 802.11a or 802.11a/g, channel selection is less important, skip to "Reducing Wireless Network Traffic".)
To see all your options start with: Improving Wireless Range: Overview

If you have a simple home network, and aren't close to neighbors with wireless equipment, you may be lucky enough just to choose between many channels that work well.

Complications arise when:

  • You want much better coverage than you're getting.
  • You use multiple access points or wireless routers. (Then you'll probably be using more than one channel.)
  • You aren't the only person nearby running a wireless network.

Simple Spacing of Channels

As explained in Improving Wireless Range: Overview, improving signal strength is not like adding more lights to get a brighter livingroom. Devices that transmit powerfully - such as routers, access points, and cell phone base stations - confuse one another. It's necessary to distance them and to have them use different channels.

For 802.11b and 802.11g, there are 11 channels for wireless equipment (13 channels in Europe). In the simple situation where there's little interference, you can choose any channel that works for you. When there is interference from wireless networks that overlap with one another, each network should use one of the non-overlapping channels: 1, 6, or 11 (1, 7, 13 in Europe). Then, 3 networks can use the same space with minimum interference. If you can't do that, choose channels as widely spaces as possible.
You can use a combination of access points and antennas and other equipment to create local "spotlights" of strong transmission, rather than trying to cover everywhere.

What If a Channel I Want to Use Has Too Much Noise (Interference)?

If your neighbor has a wireless network, it wouldn't be surprising that they are already using channel 1 and channel 11. Unfortunately, you can't completely avoid interference just by using other channels. Wireless protocols 802.11b and 11g only have 3 non-overlapping channels. Therefore when 4 or more channels are used in the same area, the level of interference can increase notably. If you and your close neighbor both have a router and a wireless access point, for example - which makes a total of four powerful transmitters - both of you will have a certain amount of interference.

If there's a severe problem, a practical and sociable thing is to talk to your neighbors using wireless networks that can be seen when you scan. Together, you can choose optimal channels for your respective networks. You'll want your own channels at least 5 apart. So, for example, you could use channels 1 and 8, and your neighbor could use 5 and 11.

You may be able to place routers and access points further away inside your homes. After all, the kinds of physical barriers that reduce your transmission range also reduce the signal that your neighbor doesn't want to see.
Super G technology is faster, but it uses two, non-configurable channels. Therefore it may not be possible to pick other channels that avoid its interference.

If you can use a directional antenna, or an antenna cable to shift an antenna, that can help you both. See the articles on antenna selection.

Reducing Wireless Network Traffic

When there's noise, your network performance drops, so one approach is not to stop the noise, but to reduce the amount of network data being transmitted.

In a noisy environment, it may be useful to keep part of your network wired. If Ethernet cabling isn't an option, consider NETGEAR's Powerline products - using existing home wiring instead of cables.

When SSID Broadcast is turned on, it's easiest for equipment to find the strongest signal. However this also causes network overhead. When the SSID is broadcast, your neighbor's equipment may keep a record of it, and automatically try to connect several times a second; this can cause significant performance reduction. So where there are close networks, turn off SSID Broadcast, and change the default SSID.

Turning off WEP and WPA may increase network throughput, but exposes your network to hackers. This is not recommended, except for testing purposes.

I am using aLinksys WAG200G router and want to add a WRE54G to improve the signal to a second PC which is in another building, 100 metres away. If I use the WRE54G close to the Router or near the second...

The new router must be located within range of the second PC. You cannot boost a wireless signal by adding routers of equal power.
If you added a router with more power (ie. more range) then it would work.

Hello, I currently use a Belkin F5D8631 as my Modem Router. I have a spare Belkin F5D7633. Can I use the 7633 as a repeater/bridge to extend my wireless range? If so, how?! Thank you

It will not extend your wireless range. If you connect your spare Belkin F5D7633 to your Belkin F5D8631, one of them would have to be set to "bridge mode" or a pass through modem so that there will be no conflicts as to which modem will receive the ip address from the network. If you set your modem/router to bridge mode, it would disable its wireless function because it will only be a pass-through device.

Range is very poor

You need to change the wireless channel of the router. Access the router's setup page through, no username, password is admin. Go to wireless tab, Select Manual Setup, change the Radio band from auto to Wide Range. Also change the Wireless network name to a different name then click on save settings at the bottom. Power cycle the router, unplug it for about 30 sec then plug it back in.

Very poor wireless range

Hello Wee Mich

You can check the documentation for your router HERE and see if there're any settings you can change.

Is there a lot of brick, concrete or metal in the walls of your home?

Have you tried using wireless repeaters?

They can improve things considerably under the right conditions.

The real issue is wireless radios work best LOS (line of site). So, even having a powerful antenna may not do much good if it can't get through the structures in your home.

Upgrading your wireless equipment, strategically locating your router, upgrading your devices' wireless antenae and using repeaters to effectively send signals 'round cornes can help a great deal.

Below are some common tips for improving your wireless network's performance.
