looking for the easiest way to inprove signal strength for LAN without devices or attachments?

Question

How can I improve the signal strength for my computer when running wireless. Signal strength tends to drop and elevate regularly.

Answer 1

Insufficient range is a common problem for many wireless networks, but there are ways to extend your coverage area into the places you need it most.

1. Center your router.

A vertical antenna and its radiation pattern.
Setting up a wireless network is like investing in real estate: it's all about location. Unfortunately, it's hard to know exactly what your coverage area will be before you install the equipment. Transmission power, antenna sensitivity, and environmental conditions such as walls and furniture all help shape your coverage area. Moreover, the router alone is not responsible for your range. Your computer's wireless adapter must also be able to transmit data to the router. An ultrapowerful router with a sensitive antenna transmitting at 1 watt does you little good if your adapter has a poor antenna and is kicking out only 30 milliwatts. Replacing your router will often do nothing to improve your range.

If possible, place your wireless router in the center of the area you wish to cover. The omnidirectional antennas on most routers radiate in a three-dimensional doughnut-shaped pattern around the pole. If your router is located in a corner of your house, much of that radiation pattern will fall outside your home. Also, consider mounting your router high on a wall or ceiling far away from furniture and shelving that can impede or block Wi-Fi signals.

2. Add antennas or repeaters.

Buffalo's router repeater kit comes preconfigured out of the box.
Some wireless adapters and routers are equipped with a connector that lets you add a high-gain antenna. High-gain antennas focus the energy they radiate in a particular direction, and you can use them to extend your range into rooms where your wireless signal otherwise might not reach. This solution works best when high-gain antennas are added to both sides of the connection.

You can also use a wireless repeater to extend your range. Repeaters receive data packets and retransmit them at full power. Unfortunately, this double duty of receiving and transmitting each individual packet cuts the throughput of your network connection in half. Repeaters can also be difficult to install, especially if you're new to networking. To make it easier, Buffalo sells a router/repeater combo that comes preconfigured out of the box. Keep in mind that repeaters tend to rely on proprietary solutions that are vendor specific and work only when you use the same brand of router and repeater. Still, a repeater can significantly increase the range of your wireless network and is well worth considering if you want to add a few rooms to your coverage area.

I know you don't want to buy anything else, but in the end, if your reception is marginal, the best thing would be to go buy a separate antenna for your wireless, at one or both ends.

That said, if you're using one of those USB wireless adapters that's just a stick, those have notoriously weak power, and are only good when you're going a short distance. I'm assuming you are unable to move closer to the source, so in that case, you would want to get either a cardbus (for laptop) or PCI (for PC) wireless card.

If you're using a linksys adapter and it's dropping, the problem could be a known software bug. If a friend can get a good signal in the same place, try some other adapter. In fact, no matter what, it's always a good test to ask a friend with a known good wireless receiver to try in your location. It could be that the location is just plain marginal, and there's really little you can do, short of getting an exotic antenna.

If you have control of both ends of the wireless, you could try changing channels - maybe there is another house nearby trying to use the same channel.
