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.

It catches network when their is strong signal but in areas that are not having strong signals it says no network coverage


Keep in mind, poor reception is not something that your service provider will fix just because you want them to. It must be justifiably cost effective for them to put up new towers, which will ultimately be criticized by cities, home owners associations, etc. Most users think there is nothing they can do to improve their cell phone reception by themselves. This is most certainly untrue, and the following will explain what you can do to ensure great mobile coverage without waiting for a new tower to magically appear.
edit Steps
  1. 1Battery. Your cell phone uses a lot more power when connecting a call than when it is on standby. Often, your battery can be strong enough to attempt a call, but not strong enough to find a signal. If you find you are having signal problems, try to keep your battery charged to 2 bars or higher.

  2. 2Landscape. Buildings and other large structures are very unfriendly to cell phone signal. Rather than making calls from deep inside buildings try moving outside or to a window to place your call. If you are having reception problems on the street try walking to the nearest intersection as they typically have better coverage. Cellular band radio waves do not effectively penetrate earth: if you are underground you will likely receive no signal.
  3. 3Install a cellular repeater. If you are having cell problems in one location, such as your home or office, then try installing a cellular repeater. Cell phone repeaters pick up low cell signal with an antenna, boost the signal and broadcast it over the coverage area. They typically need at least 2 bars of signal where the antenna is placed (usually outside or on the roof) but can substantially improve cell reception, as well as battery life and data download speeds. Some repeaters might need technical knowledge such as the frequency of your carrier, and only work for one service provider. For a less technical approach that improves reception on all carriers, use a dual-band cell phone repeater.
  4. 4Upgrade your antenna. A few cell phone manufacturers make a "Hi-gain" antenna for their handsets, which may be changed in-store or by the user at home. Although these won’t improve signal as much (or at all) as a repeater these antennas are relatively inexpensive and you are not confined to one location.
  5. 5Change networks. Most networks operate independently of one another, using their own frequencies and constructing their own cell phone towers. Chances are if the signal is bad with one network you can improve by switching. Most cellular networks these days allow you to transfer your phone number when you change provider.
  6. 6Hold your phone correctly. Mobile phone antennas are designed to project a signal outward, perpendicular to the long axis of the antenna. As such, mobile phones seek signals in a donut-esque shape around the antenna. Normally, when a mobile is held upright, this is not a problem. However, if you are holding your phone in a strange way, such as on its side or upside down, you will hinder the operation of the antenna. Hold your phone upright to guarantee that your phone can "see" your carrier signal.
  7. 7Host a cell site. This may take time, but where cell phone reception is inadequate property owners can host small cell sites on their properties for major wireless carriers. 3rd parties with Wireless Revenue Programs allow you to register your property to be eligible. Then when there is carrier interest in the area you'll be on the short list of places they choose from and will have optimal coverage. They may even pay your phone bill.

Excellent signal low speed transfer


You can boost the signal range of a WiFi computer network in several ways: Answer:
  • reposition your router (or access point) to avoid obstructions and radio interference. Both reduce the range of WiFi network equipment. Common sources of interference in residences include brick or plaster walls, microwave ovens, and cordless phones. Additionally, consider changing the WiFi channel number on your equipment to avoid interference.

  • upgrade the antenna on your router (or access point). WiFi antennas on most wireless base stations can be removed and replaced with more powerful ones.

  • add another access point (or router). Large residences typically require no more than two APs, whereas businesses may employ dozens of APs. In a home, this option requires connecting your primary wireless router (access point) to the second one with Ethernet cable; home wireless routers and/or APs don't normally communicate with each other directly.

  • add a bi-directional WiFi signal amplifier to wireless devices as needed. A WiFi signal amplifier (sometimes called "signal booster") attaches to a router, access point or Wi-Fi client at the place where the antenna connects. Bi-directional antennas amplify the wireless signal in both transmit and receive directions. These should be used as WiFi transmissions are two-way radio communications.

  • add a WiFi repeater. A wireless repeater is a stand-alone unit positioned within range of a wireless router (access point). Repeaters (sometimes called "range expanders") serve as a two-way relay station for WiFi signals. Clients too far away from the original router / AP can instead associate with the WLAN through the repeater.

The parent unit does not recognize that the nursery unit is on. all the correct lights are displayed on the nursery unit for normal function, but the parent unit display indicates that the nursery unit is...


Sounds like the units need to be paired. Start with all units off. Then turn on one of the parent units. Press and hold the menu button until it beeps. Quickly turn on the nursery unit and press and hold the button on the nursery unit that has the parent unit icon below it. After a couple of seconds the units will pair. Repeat this process with the other parent unit.

Delphi SKYFi3 XM Radio Repeater


You begin by setting up your existing (((XM))) antenna the one that came in your home kit (not included in repeater package) in a location that gets good reception of the (((XM))) signal. This may be outside, or on a south facing window sill. This antenna gets plugged into the rear of the Delphi (((XM))) Radio Signal Repeater Transmitter. A power jack is right next to the antenna connection, and should be plugged in and to the wall with the included power supply. There is also a "PWR OUT" selector switch on the rear of the unit which allows you to control the strength of the signal transmitted from the unit.

Once the power and antenna are attached, both blue indicator lights will light up on the face of the unit. The blue antenna indicator will light up only to signify that the antenna is attached correctly. It does not let you know whether your antenna is in a location receiving a good (((XM))) signal or not. You will have to look at the signal strength indicator on your (((XM))) radio receiver do determine best location for the (((XM))) antenna.

Once you have this setup, place the Repeater Antenna close to your existing (((XM))) Radio and plug it into your antenna jack on the (((XM))) radio cradle. This connector is identical to your (((XM))) Home Antenna provided with all Boom boxes and (((XM))) home receivers and kits so compatibility is guaranteed. The Repeater Receiver Antenna does not require any separate power connections. Hope this helps!

There are many different (possibly fun) ways to boost your routers signals. You can purchase better antennas (If you can disconnect your OEM ones, but those can be over priced). You can upgrade the firmware of your router (requires very good technical skill to properly and safely do that), then tweak those router settings then. You can make you own antennas. ( that requires some radio engineering skills to properly do). You can install an amplifier between the router and antennas (can be expensive). or any combination of the above, but be wary of FCC rules with any modification of RF equipment (don't make the signal too powerful, or cause interference to others in your area). :D

One more viable way is to use a repeater in another area of your home to repeat your routers signal where needed (repeaters are hard to find, can be expensive as well).

Escort 8500 radar detector


Service Required means that your 8500 has repeatedly failed while attempting to calibrate its radar antenna. This can be fixed by Escort for free if your RD still is in warranty. There is a service fee if your RD is out of warranty, but at least Escort will fully test everything in addition to repairing your 8500, and they will upgrade your 8500's firmware to whatever their latest and greatest firmware is which may help to improve sensitivity, reduce false alerts, or to detect newer laser gun models.

Jensen MSR4050G Sirius Ready marine radio


I had the same problem and there are a couple of reason why you may not be able to get into Sirius Mode.

  1. You have the wrong type of antenna (it must be a Sirius approved antenna)
  2. You may not have installed the tuner (most Sirius ready units need require that you have a tuner hooked up to your unit to get satellite reception. The tuners are specific to your unit, so make sure you but the correct one. This is quite sneaky on Sirius’ part…but good luck).

MH z


1.9GHz for the PCS Data communications and the 800MHz Band for CDMA Voice Communications. It's likely the 800MHz repeater will function for this phone, provided it is intended as a mobile phone repeater. The data functionality (web, email, mms, etc.) may be limited still, but my guess is that if you are in an area that requires a repeater, you may have limited or no PCS data service anyhow.
