- Do I need to have an account with a WiFi service provider to use wireless?
No. With regards to using wireless in your home or office, all you need is a broadband connection, like high speed cable, DSL, or a T1 or T3 line. When your using a wireless network to connect to the internet, the wireless part only concerns your LAN. When you are on the road, and you connect to a wireless hotspot, if it is a public hotspot then you don't need a subscription. If it is a private hotspot, like a restaurant or cafe, they may require you pay a certain fee for using their wireless connection.
If you are in a location where there is no high speed internet service, you may want to see if there are any Wireless Internet Service Providers (WISP) in your area. There most likely is and if there is not, maybe you should consider becoming a WISP and offering high speed wireless internet to your neighbors. Please contact us to become a Wireless Internet Service Provider.
- What distance can I get with my internal wireless card in my laptop?
- What PCMCIA card do you recommend for my laptop?
- Can I mix wireless equipment from different vendors?
- What is the range of wireless equipment?
Range of wireless devices depends on many things. For a typical laptop with no external antenna connected to it, you can expect to see ranges varying from 50 to 150 feet. Although manufacturers state 100 to 300 feet, this is assuming ideal conditions and is not practical for everyday usage. With a high gain antenna connected to the product, the range can be greatly extended and is limited to LOS (Line-of-Site), the curvature of the earth, and the gain of the antenna. The higher the gain, the stronger the antenna.
Typical indoor ranges are around 100 feet, but can be shorter if the building construction interferes with radio transmissions. Longer range is possible, but the performance will decrease without the use of high gain antennas.
To extend the range of wireless equipment, add another access point, increase the antenna gain, or add a repeater to your wireless network.
- Can I have more then one Access Point on my network?
Yes, multiple access points can be connected to a wired or wireless LAN. Most of the time, another access point will be added to include wireless connectivity in another part of the home or office. For homes with multiple floors, it is recommended that a repeater be placed on each floor to allow for better access throughout the home.
Areas that are too large for coverage using one access point should try using repeaters or high gain antennas. This will increase the coverage area to allow for better roaming and wireless connection.
- What about security?
Although wireless networks are generally easy to install and setup, you want to be sure to take the necessary steps to secure your new wireless network. Unlike a traditional network where an intruder has to be physically connected to your network to gain access to data, a wireless network is much different. With a wireless network, information is being transmitted through the airwaves, so anyone within range can potentially gain access to data, unless the necessary steps are taken to prevent it. Here are some basic tips on securing your wireless LAN. For more detail on wireless security, click here.
1. Disable the SSID broadcast option. This will force users to know your SSID before connecting. Use directional antennas if you plan to connect point to point wireless, or point to multi-point wireless.
2. Change the default SSID (network name). The SSID is the name of your wireless network. Although it is not required, the SSID should always be changed to something unique that you can remember.
3. Enable MAC address filtering. The MAC address is a unique set of digits assigned to each networking device. With this filtering enabled, the client device must be entered into the Access Point or Router list of allowed MAC addresses before it is able to connect. This prevents unknown people from entering your access point unless allowed.
4. Change the default password needed to access a wireless device. This is the password that is prompted for each time you log into your access point or router. There is a default password set by the factory, on the devices, but should always be changed. A hacker knows these default settings and can use them to gain access to your device and change your settings. This should be one of the first things you change when setting up your equipment.
5. Be sure to use a combination of MAC filtering and either WEP or WPA encryption. Although none of these encryption types can stop the most talented Wireless Hacker, using a combination of encryption methods will make your Wireless Network as secure as possible.
6. For point to point, and point to multi-point wireless connection, use a frequency other then 2.4GHz.Such frequencies are 4.9GHz for public safety, 5.8GHz, or 900MHz. These frequencies are much less common, and will less likely be used by perpetrators to gain access to your wireless LAN.
- What is broadband?
This networking term has several definitions. The one most relevant to wireless networking is that Broadband, as opposed to narrowband, simply means more bandwidth. Broadband is faster then a dialup connection, or about 64Kbps to 45Mbps. Broadband is needed for wireless networking because of the fact that a broadband connection is "always on", and therefore can be shared.
- Why choose a wireless network?
- Freedom—work anywhere
- Quick, effortless installation
- No cat5 cables to run
- Easy to expand/upgrade
Wireless networks have become more popular and have came down in price. Since they don't require cables, you can use the devices anywhere in an office or home, even out on the deck or poolside. Running Ethernet cable in the house is no longer needed which saves time and prevents damage to walls and floors-you can network anywhere—wirelessly. When on the road, wireless networking is available all over in hotspots at coffee shops, businesses, airports—great when you're away from home and need to get some work done. For convenience, and for the future, wireless networking is the answer.
- What is RTS Threshold and when should it be used?
This setting determines the packet size at which the device issues a request to send (RTS) before sending the packet. A low RTS Threshold setting can be useful in areas where many client devices are associating with the access point or in areas where the clients are far apart and can detect only the access point and not each other., wireless networking is the answer.
- What can I do if I am having wireless connection problems?
Signal strength drop or fluctuation are common causes of RF interference.
- Change the channel on your access point or wireless router. Use only channels 1, 6 or 11 for non-overlapping channels.
- Change the location of your wireless products. Subtle changes (2-3 feet) can make a big difference. Do not put the access point or wireless router in a cabinet or enclosure.
- 2.4GHz phones, X-10, and Bluetooth devices will interfere with your wireless network. Change the location of the base for your phone, or downgrade to 900MHz phones, or upgrade to 5.8GHz phones.
- The wireless signal will degrade (or die completely) when going through brick (fireplace), metal (file cabinet), steel, lead, mirrors, water (fish tank), large appliances, glass, etc.
If your wireless connection is only dropping during large file transfers or when a large number of wireless clients are connecting, change the preamble on all wireless devices to short.
- Why is Low Latency important for a Point to Point Wireless backhaul?
Low latency is required when VoIP or Video is being streamed across the wireless link. For a low latency connection, total packet delivery time needs to be 100ms or less. For voice applications, low jitter is also important. Latency is the time it takes for packets to be transmitted between the two radios.
Jitter is the variation in latency. It is the difference between the fastest and slowest packets being transmitted on your wireless backhaul. Low jitter is the most important feature when transmitting voice or VoIP across the wireless backhaul.
- How do I reset the Access Points included in the GNS-1150?
Remove the 4 screws on the back of the access point. Slowly, and carefully remove the cover, and expose the radio board as shown below. You will notice 2 reset buttons. Hold down RESET BUTTON #1, for about 10 seconds, or until the light flashes. Next, hold down RESET BUTTON #2, as shown, for about 10 seconds, or until the light flashes. Power down the radio, and then power back up. Allow for about 45 seconds for the radio to boot up. You should now be able to log into the default IP address of 192.168.2.66.
FAQ HOTSPOT/WIRELESS ISP
- What's a Hotspot?
A hotspot is an area with a high-speed Internet connection and wireless connectivity. A Hotspot is another name for broadband wireless internet access, and can be either public or private. After you find an area with wireless access, you need either a handheld device with wireless capabilities, or a computer with a functional wireless adapter. Configuration depends on the provider.
- What is a WISP?
Wireless Internet Service Provider. A WISP is a company or individual that decides to offer wireless internet access to the public for a weekly, monthly or yearly rate. Usually a WISP will be setup where high speed internet access is not available. Wireless 802.11a/b/g requires line of site, so location is a must when planning to become a wireless provider.
- How do you find a public Hotspot?
Most businesses, colleges, hotels, restaurants, coffee shops, airports, marinas, libraries and wireless service providers publicize their public hotspots. There are also many websites available to visit that will guide you, no matter what state you may live in, for help finding these hotspots.
- What equipment do I need to become a WISP?
Depending on your location, the equipment needed to setup as a WISP may vary. Distance, line-of-site, elevation, and other obstructions effect the setup of your base station. For more details of setting up a WISP, please go to our WISP setup page, or email us a diagram of your layout and desired coverage area, to firstname.lastname@example.org.
- What equipment do I need, to share internet with friends and neighbors wirelessly?
In order to share your internet connection with friends and neighbors, you will first have to be connected to a high speed broadband internet connection. After you have determined that, you will need to determine how far away your neighbors are and if they are in Line of Site to you house or not. We recommend attaching an omni directional antenna on the roof of your location and then attaching between a 8dBi and 14dBi antenna on your neighbors roof. Depending on distance and obstructions, depends on the type of antenna needed. If there is no line of site, between you and your neighbor, please contact us for recommendations.
- Do I have to use both antenna ports on the Linksys device?
No. Although the Linksys access points and routers have two antenna ports on them, this does not mean that they both have to be utilized. It is a added benefit of the Linksys router that it has two antenna ports. On the management setting, you can select whether you want to use the left, right or diversity antenna.
Many people think that since the device has two antenna ports, that one is transmitting a signal and the other antenna port is receiving a signal, this is not true. Both antenna ports are transmitting and receiving. When using the AP as a bridge, if you only have one, high gain antenna connected to the Linksys AP or Router, then go to the management settings, and select which antenna port you want to use.
- On the Linksys AP or Router, which is the right antenna port?
When looking at the unit from the front, the right antenna is on the right side, and the left antenna is on the left side.
- Which antennas are compatible with D-link and Linksys devices?
Any 2.4GHz antenna is able to connect to a 2.4GHz D-Link or Linksys, or any other device with a removable antenna that operates at the 2.4GHz range. Although the wireless devices have different connectors on them, we can adjust to the connectors by giving you the correct cable or pigtail to go from the antenna to the wireless device of your choice. Depending on the gain of the antenna, depends on how far you can run an antenna cable.

FAQ WIRELESS BRIDGE KITS
- What is a Bridge Kit?
A wireless bridge kit is a point-to-point connection of two computers or networks, between two locations, connected together wirelessly. For Example, A bridge kit enables businesses or homes that own two locations to be able to share files and/or internet access, easily and more affordable.
- How do I setup a building to building link between 2 locations?
- How long do I have, to run an antenna cable to my device?
- Do I need high gain antennas on each end of my Bridge?
If your bridge is more then 100 feet in distance, then you should have a high gain antenna on each side. Upgrading the antenna on one side only will not help the wireless connection you are trying to achieve. In order to have strong signal strength between the bridge, a high gain antenna is recommend for each side. Check out our bundled Wireless Bridge Kits here. Using a high gain antenna, will also eliminate wasted WiFi coverage in areas where you do not need it. Such areas can be used by perpetrators to try and gain Internet Access off of your network. Directional antennas will concentrate the wireless signal to a specified area that you choose.
- How can I place the Access Point near the antenna if there is no power outlet?
If your antenna is on the roof, and your access point is located where you would need 100 feet of antenna cable to connect to it, then you need a Power over Ethernet adapter, or POE. Running 100 feet of antenna cable will be expensive and have a lot of db loss, which will decrease antenna performance.
The POE adapter will allow you to place the access point closer to the antenna, and allow for a shorter run of antenna cable. This usually results in mounting the access point in the ceiling or the attic where there is no power. The POE adapter will power the access point through the Ethernet cable, and eliminate the need for an extension cord to the attic. Typical Ethernet cable can be run up to about 300 feet, without loosing signal.
The POE adapter used has to be made by the same manufacturer as the access point you are using. So if you are using a Linksys AP, then you will need a Linksys POE. For more info, contact us.
- Do I absolutely need Line-of-Sight between my two locations?
If you are connecting two locations wirelessly, then we recommend you try to have Line-of-Site. This usually means having to mount the antennas on the outside of your location, preferably on the roof. All of our Bridge kits now come with mounting hardware so it is much easier to get the antennas mounted properly.
If you cannot get LOS between the locations, then you should go with a Non-LOS bridge kit. These antennas are more expensive, because they have a multi-polarized radiation pattern that allows them to send a signal through obstructions like trees. GNS Wireless also carries a number of 900MHz point to point links, or a 5GHz point to point link. Depending on what type of obstruction is blocking your LOS, will depend on which is the best solution for your application. Contact us for more details.
- Is having a wireless connection between two buildings secure?
Yes, it is possible, with the correct security measures in place to establish a secure wireless network between two or more points. When connecting two locations, point to point, some of the security measures you want to consider using is to hide the SSID of your network, use a frequency other then 2.4GHz, (5GHz, 900MHz, 4.9Ghz), use WPA with MAC filtering, or higher encryption levels such as AES if available. Using directional antennas, which come in all of our bridge packages also, reduce the threat of transmitting WiFi into areas where perpetrators will have the ability to gain access. Please refer to the hardware manual for exact security solutions available for the Access Point you wish to use. Each manufacturer will offer different levels of security, depending on how secure you wish your link to operate.
