Unable to find wireless network

My laptop cannot find any wireless networks. I have a wireless symbol PDA that I use for work and it finds my home network plus 5 of my neighbors networks. I have run every troubleshooter and diagnostic program I can find. Everything says the hardware is working and enabled and good to go. I can sit 2 feet from the wireless router and my laptop cannot find it.

WHAT'S UP????

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 have a Linksys Wireless router that hasn't caused a bit of trouble since I installed it several years ago. Now, however, I am experiencing some odd things... for example, I can not watch videos that are...


There are many causes for poor wireless connections, and many solutions:

First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.

Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.

In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4.

Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna should be vertical.

Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. If your current network is not listed, enter its info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".

If the above does not fix your problem, download and install the latest driver for your wireless card.

Some users have reported improved wireless performance by switching to WPA encryption.

If you continue to have problems, try the following:

For wireless g routers, try setting the "Transmission Rate" to 54 Mbps.

If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.

Do a wireless scan on your computer and out how many wireless access is in your neighborhood. More than likely that your router is sharing the same wireless channel number as your neighbor's. Go to your router and cheange to opposite of what your neighbor is on.

How do I switch on wireless on amilo 1505 please?


Check if the wireless device is installed and working properly on your machine.
Go to >> My PC >> properties >> Hardware >> Device Manager >> network devices

Run a wireless network connection (Start >> Control Panel >> Wireless )

Do you have any wireless network running in your home?
If not you will not see any signal from the wireless devices.

(but it is probably instead that you can see all the wireless networks availables on range with your device (eg.:your neighbor)

IPAQ wireless connectivity


always start with the simplest answer first so make sure you have WiFi turned on. Think back, have you changed the wireless security on your router? If so you may need to re-enter the network details or add your iPAQ's MAC address to the access control list on the router. In the bottom right-hand corner of the home screen you should have a small HP Wireless symbol, if you tap it you should get your HP Wireless control panel on screen and can 1: turn WiFi on and off, 2: manually enter the WiFi network details and 3: search for WiFi networks in range.

Wi-fi PDA connectivity problem


First, restart your pda by using your stylus and pressing the pin-hole sized button on the back of the PDA. There are sometimes a couple of different reasons why the pda wont recognize the network. Main Reason: Make sure you are at the home screen... Tap the wifi icon on the lower right corner of the pda. T hen make sure that the WLAN power is turned ON. Press the setting button. If you see your network in the list, tap on it. It should bring up a network configuration window. Make sure it says it connect to "The Internet". Then tap on the "Network Key" tab at the bottom of window. If you have no security settings on your belkin router, make sure Authentication is set to Open and Data Encryption is set to "Disabled". Then press "OK". That should Be it!!!! Let me know if this way doesnt work, or if something doesnt make sence!
