Question about D-Link DI 514 Wireless Router (DI-514)
Wireless connections work at best 30% of time. All new computers can detect wireless router but connections are far and few between. Can anyone provide potential fix?
There are quite a few variables that can affect signal quality and ultimately the ability to connect. Of course, having the proper SSID and security credentials (or "keys") are required. The type of security employed on the router must be supported by each device that needs access. An example is a device that offers WEP security will not be able to connect to a router that runs WPA or an even more robust security system software running on it. Since you're able to connect 30% of the time - I'll assume that you have the proper credentials in place on all devices expected to connect to the router, with one exception: Make sure you're connecting to your router. Verify the SSID of your router. You may be close enough to a neighbor's router with a different SSID on some devices and are attempting to connect to it - with the wrong credentials.
Next is location. Locate the wireless router in a location that is central to the devices that will connect wirelessly. A location on the first or second floor is better than a basement location - unless all the devices to connect are located in the basement.
Consider the surroundings. WiFi is a radio signal that operates on 2.4 Ghz. This is the same frequency as many newer cordless phones, baby monitors, etc. All off these devices are competing for "space" on that frequency. It's like driving between to nearby cities that have a radio broadcasting on 98.5 - one plays music and the other is talk radio - you are unable to listen to either really until you get closer to one or the other. See if these types of devices are limiting the range of your WiFi by unplugging the AC power from these devices - and on the remote handsets - remove the battery. Power them up one at a time to see which is reducing the signal. You may be able to experiment with a new location for this device - or discontinue its use.
What type building materials? Obviously simply wood and drywall is relatively easy for WiFi signals to penetrate, but multiple layers of it and concrete, aluminum, brick and others are significantly more challenging. Experiment with relocating the WiFi router to see if there is a better spot for it - I know it's easier said than done, but that's the way it is.
Antenna upgrade. Some routers have detachable antennas and can accept more powerful antennas. Some manufacturers sell them for their products, too. LinkSys at one time sold a pair of 7 db gain antennas for about $50 or so. These antennas can and do make a difference - but only if your router supports a removable antenna.
There's a lot to digest here - hopefully one or more suggestion will allow you to connect reliably again. Please rate this response and good luck!
