my wireless signal comes and goes sometimes i can get on the internet and sometimes it does not work at all???

Question

the routers are brand new

Answer 1

There are many things that can cause you to loose your signal on your wireless connection.

1) 2.4Ghz Cordless phones. These operate in the same frequency range as your wireless networking devices. Move the base stations of the phones as far away from your wireless router and wireless computers as you possibly can, at least 10 feet or get an older 900Mhz or the newer 5Ghz phone.

2) Other Wireless Networks in your area. If your neighbors have wireless networks close to you and transmitting on the same channel as yours it can cause some major drop outs and slow connections. I would use a program to look at all the wireless signals in your area to see what channel they are transmitting on. Most routers default to channel 6 and most people dont know enough about wireless to change them if needed. Download a program called netstumbler http://www.netstumbler.org , and look at what channels other wireless networks are using. The best channels to use, because there is less frequency overlap in them, are channels 1, 6 and 11. If you see others using the same channel as your change the channel in the router to one that is not being used close to you.

3) Walls, Floors and ceilings. The more dence the material used in the construction of your home the harder it is for RF signals to travel through it. Also, certain insulation materials, like fiberglass in alumanim casing, will also cause poor signal penetration. If you are having problems with getting a signal to a computer far away from the router the first thing I would do is purchase and install a High Gain Indoor Omni Directional antenna. They are less then $100 and just plug into the back of your router were the other small antenna is connected to right now. This will boost the amplitude of your signal. If it is still not enough you may need to purchase a Range extender. A range extender will pick up the signal from your router and transmit it at a greater power level so it is can get to those bad spots in your house. I would recoomend you use a range extender instead of a Access Point just because with a Access Point you need to run a ethernet cable from your router tp the Access Point and most people dont like to have 20 or 30 feet of ethernet cable running through there home.

Hope this helps....

Answer 2

Ditch your 2.4GHz cordless phones and get new DECT 6.0 compliant cordless phones.

Change the SSID of your router to something other than the default

Use netstumbler (http://www.stumbler.net/) to see what channels that your neighbors are using and use a channel that is as far away from them all as possible.

Disable any Bluetooth devices that you aren't using.

If your house has lathe and plaster walls, you'll need to buy at least one.. probably more Wireless Access Points to add to your network. Lathe and plaster = concrete and WiFi frequencies doesn't go through concrete very well.

And did you say "routers" plural? Why buy more than one router? Take one back and get a Wireless Access Point instead so that all hosts on your network can communicate with each other.

Good Luck,

Answer 3

It could be caused by interference. Change the channel of your wireless network (1, 6 or 11).

Answer 4

When this happens, it is possible that the router does not have a connection to the Internet. That could be because even though the electricity is on, the Internet provider that the router is connected to is still not working.
