Check with your local computer store for this issue.
There should be an antenna on market that is compatible.
I would relocate the router in another location and see if the reception is better. Try to relocate the router away from cell phones or cordless phone and or digital TV's about 20 ft is desirable.

WIRELESS OUT OF RANGE


Move closer. That's not always an option though. Here are some tips to improve the range of wireless routers:

1) Locate the router higher in the building rather than lower (1st or second floor is better than a basement location).

2) Place the router in a location that will offer the least resistance to the signals - it is easier to pass wifi signals through gypsum board than it is for concrete / brick or walls with aluminum siding on them.

3) Change the antenna(s) on the router to a type that offers more gain. Typical router omni directional antennas offer 3dB to 5dB or gain - there are others that offer 7 dB or more of omnidirectional gain for reasonable prices. The antenna gain works for both transmit from and receive to the router.

4) if the device you wirsh to connect to the router is in one place, consider a directional Yagi antenna. These antennas concentrate the entire wifi signal in a direction that is 30 degrees wide and can allow the signal to be seen 5, 6 or even more times further in one direction - instead of being spread out over 360 degrees. These antennas cost a little more, but can solve the problem quickly.

5) Replace the manufacturer's stock firmware of selected routers with a 3rd party type such as DD-WRT or Tomato. Either of these will work with your Linksys WRT54G router. One of the benefits is the ability to boost output power of the wifi radio in the new settings the firmware offers. Read about both and decide if either is something you're comfortable doing.

6) Add additional wifi routers configured as a bridge or an access point to extend the wifi signal into an underserved area. DD-WRT supports bridging as shown here.

I hope this helps & good luck!

How to improve signal strength on a wireless network


The success of a wireless network depends on the signal strength. A strong signal is required so all networking devices can communicate with each other. A weak signal causes low bandwidth preventing communication between hosts and causing network disruption. <br /> <ol> <li>Pay attention to router placement. It should be away from walls, floor, and glass and metal objects, all of which disturb wireless signals. If possible, place the router in a central location.</li> <li>Change your router's standard antenna to use a high-gain antenna that sends signals in one direction. This way signals can be focused in the required direction. Standard antennae send signals in all the directions, which may not be desirable especially if the router needs to be placed next to a wall.</li> <li>Use a wireless repeater, the device that enhances range of a wireless network.</li> <li>Change the channel on which the router is functioning. Similar to radio stations, routers function on different channels one of which may give better performance than the other.</li> <li>Ensure the network card installed in the hosts is capable of receiving and sending signals to the router. In this respect, using equipment from one manufacturer is better.</li> <li>Check the vendor's site regularly for latest updates, performance enhancing tips and fixes.</li></ol> if you need more information regarding improvement of wireless network, visit<a href="http://www.microsoft.com/athome/setup/wirelesstips.aspx"> THIS</a> site.

How to improve wireless connection


Wireless signals often get dropped because the channels are congested or the signal is weak. Some routers / access points can scan for the least cluttered channel and some allow you to remove the standard antenna and replace it with a higher gain antenna.

Place the access point as high and as central as possible.
Try to use a free channel.
Failing that change antenna to high gain on router and PC.

(some laptops just **** at wireless no matter what you do, I have a dell m6500 that is useless on wireless)

How do I strengthen my wireless signal? I am using a Linksys router.


The easiest is to replace the small antenna with a higher gain one. You get some very effective 8+ db gain omni directional antennas for linksys on ebay, amazon etc.
If you are in one direction you can also use a Yagi antenna (Directional) with high gain (20+db gain)
Normally the problem is not just the router, but the connecting device as well.
Keeping in mind you have 2 way comms between 2 devices. The router and say a laptop. ideally you should upgrade both antennas. As the best antenna on an Linksys AP will not fix a weak laptop signal. (it will transmit better, and receive better, but the laptop should also transmit and receive better)
Hope it helps

This wireless router is in our study where we have a PC and there are not any problems with the signal in here but if we use a laptop in another part of the house, at best we only get a weak signal which...


It would be good to know the model and make of your router. This would indicate which of the 802.11 standards it is capable of. These standards are indicative of the routers range. Range can be impeded by environmental issues like walls, appliances and wireless phones that are on the same frequency. Wireless phones can operate on the same 2.4Ghz frequency as a wireless router hurting its range.

Now, as for a fix. Depending on the router, it may be possible to replace the antennae with a higher gain antennae. If the router has a standard connection, a replacement can be purchased. If the router is one of the earlier standards (A, B, or G) you may want to considered a newer router for example a Wireless-N with MIMO router. Often these have multiple antennas to help improve performance.

Please respond back with your routers information if you would life more input.

How can I increase my WIFI range. My internet signal is very weak when I am in my bedroom. Can I increase my range by possibly buying a signal extender.


Try moving the wireless router around and or higher.
If the wireless router is in a different room and the room has concrete walls of foils insulation in the walls, this will weaken the wireless signal. AND/OR
You can connect add a antenna to your computer. Have a look at this device. Normal 0 USB High Gain Antennas www.pricewatch.com/gallery/networking/high_gain_antenna

I have three computes connected to my router. Two in the same room and one in a room less than 30 feet away. The one in the next room has a low signal of two bars and I want to know how I can improve this...


You can buy a bigger antenna. You can find them on websites like directron, or any other computer website. It's called a high gain antenna. Wireless signals are greatly reduces when they have to go through certain surfaces, like walls, brick and the like. Another thing you can do it put the wireless router closer inbetween them. Or even up in the attic.

The weak signal is due to either physical barriers - walls etc, distance from transmitter (router) or interferance (other netowoks broadcasting) You may be able to improve things by

  1. raising the router up higher
  2. move to a more centeral location in house
  3. changing the supplied antenna for a high gain antenna
  4. placing an "external" antenna on the router EG ensure it physically connects to your router though before buying - check you router manual for the correct connector type. Also some routers donot have detachable antennas
  5. change channel that wireless router operates on
The one that will not connect what OS are you running?

what have you tried so far

OK maybe get an external antenna in any event place the Unit/Antenna up as high as possible... also ensure ya aren't near any large metal objects/power wire junctions etc, but generally an external antenna will Boost ya signal, also even just moving "it" somewhere else can make a big improvement... In some wifi routers ya can increase and decrease ya output, ya may wanna check ya manual to see if yours is one of those? Ya may also want to try changing "Channels" on the Router too.. this also has been known to help. Good Luck :)

Compatibility with Sitecom wl 031


This 10dBi omni directional antenna enables you to very easily extend the range of your wireless network. By linking the Omni Antenna to your wireless router, you gain the benefits of an optimum wireless signal while minimising the number of ‘dead spots’ (points in your home where the signal is either weak or lost).
However it does not fit the following types of routers,modems and accespoints:
WL-143
WL-122v2
WL-114/WL-517
WL-114v2
WL-108/WL109
WL-111
WL-106
WL-025
WL-018v2
These antenne's will also fit other brands of wireless products that use an SMA connector
