Recently I have been facing a wireless drop out problem from my network. My 802.11g network card is working quite strange these days, says I’m approaching the end of download or surfing through the internet quite smoothly and in the middle of Skype call with my girl, without a sign, my Wi-Fi connection drops suddenly. I then keep retrying to connect back my router, but the blinking signal seems off the air. Few minutes later, the connection miraculously resurfaces. If you also have this kind of problem, don’t blame on your local broadband company server first. Try to solve the problem by yourself from the information below.

One of the biggest reasons for wireless interference is the use of 802.11g or 802.11b networks and 2.4GHz cordless phones. Router for those networks and 2.4GHz phones operate in the same frequency, and they’re competing with each other. This is exacerbated by the fact that they’re in the same room. Interference from wireless products in the 2.4GHz frequency is a known issue for 802.11g/b networks; even baby monitors and microwave ovens have been known to wreak havoc on Wi-Fi networks.

These steps will help you create a stable, always-on wireless connection.

1. Change channels.
   Interference is a likely cause of intermittent connections. All 802.11b and 802.11g networks operate at 2.4GHz, in a small swath of spectrum once used primarily by ham-radio hobbyists. Today, these radios, plus other Wi-Fi gear, Bluetooth devices, cordless phones, microwave ovens, baby monitors, and wireless surveillance equipment, all crowd the spectrum. When these devices compete for the same airspace, they interfere with each other, potentially blocking each other’s signals. Luckily, there are ways to sidestep and minimize interference in many situations. In the United States, 802.11b and 802.11g devices can be configured to operate at any one of 11 channels. Unfortunately, these channels overlap with adjacent channels, so you have only 3 non-overlapping channels at your disposal: channels 1, 6, and 11. If you and your neighbor both have a wireless network, both of which are set to channel 6, you may experience interference. You can remedy the problem by resetting your wireless router to a different, preferably non-overlapping, channel, in this case, either 1 or 11.
2. Replace your cordless phone.
   Cordless phones are among the worst sources of interference for wireless networks. For example, my cordless phone is putting away separately with the base and therefore they tend to transmit frequently. But the base is just near to Wi-Fi router, this makes sense the frequency they all sharing among each has a big interference. One solution for this is to divide them into different channel. Unfortunately, my 2.4GHz cordless phone doesn’t have the function to allow me to do that so I quickly head to my router setting to change a different one. Generally, it’s not a good idea to place a cordless phone next to a Wi-Fi router. If this doesn’t help, consider replacing your 2.4GHz phone with a 5GHz phone. This way, your phone and network won’t be sharing the same airspace and won’t interfere with each other.
3. Expand your wireless network.
   The farther you are from your wireless router, the greater the potential for interference to block or to slow your connection. For example, you may be able to connect just fine in your house, but on your patio, you may have an intermittent connection that disappears whenever your neighbor is using her cordless phone. The signal on your patio may be too weak to cope with the interference coming from the house next door. You can strengthen the connection with antennas or repeaters, or a power-line bridge to import the connection from your router to your patio and feed it into a power-line access point. Instead of the weak signal from your distant router, you now have a strong signal from an access point placed right where you want to buttress your coverage area.
