Optimizing the Router for Better Wireless Connectivity

If you're downloading a large files and it's coming to it's end, you're receiving a Skype call from a client in London, without warning, your Wi-Fi connection drops, leaving your download and VoIP call in havoc. You'll retry the wireless connection, but your router, though blinking contentedly in your tense, seems to be off. After three hour, for no reason, your Wi-Fi connection miraculously resurfaces.

Wireless networking can be a easy and yet gives you a headache, It's great when it works and a mind-numbing frustration when it doesn't. A common complaint among many who have moved to Wi-Fi is that their wireless connection mysteriously fades in and out the frequency.

These steps will help you to create a stable, Always-on the wireless connections.

1. Replace your cordless phone. Cordless phones are among the worst sources of interference for wireless networks. They intend to transmit at a higher power output than Wi-Fi gear, making them louder and therefore harder to talk over, and they tend to transmit frequently, especially when the handset and base station are separated. Some 2.4GHz cordless phones let you select a channel, in which case you can try separating the phone's frequency from the frequency of your wireless network. For example, set your phone to channel 1 and your wireless router to channel 11. If your phone doesn't let you select a channel, try putting some distance between your phone and your router. 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.

2. 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 you can use 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.

3. Change channels. Interference is a likely cause of intermittent connections, such as the one described above. 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.

Top iPod Problems and How You Can Fix Them

Most say the small shape of the iPod is an advantage, while others argue that the increased mobility just increases the chances of an accidents happening.

The most common accident the iPod faces is simply being dropped. This kind of accident can happen anywhere at any time, and if it happens to drop outside on concrete you might be in trouble. The least that can happen is a minor scratch, which can easily just be ignored or buffed out. If you start experiencing hard drive problems because of the drop, you'll know something bad has happend. Although many prefer to send their iPods off to specialists for repair, some owners prefer to do it themselves.

If you're a do it yourselfer, or you just like to experiment, try buying your own parts to fix your iPod. This might be a good alternative to having it repaired, especially if you dread the time you have to wait for repairs to be completed. You can purchase broken iPods with workable parts, or buy individual screens, batteries, and harddrives on websites like eBay.

If you've owned your iPod for a year or longer, you might see signs of battery weakness. When this happens, you'll know that it's life is coming up short. A battery replacement would be a good investment in this case, and will solve the problem nicely.

Be careful if you keep your iPod in your back pocket. If you aren't careful with your iPod while it's in your jacket, pants, or pocket, it can be prone to bending and cracking. It's important to remember that the iPod isn't made out of steel, and can sometimes be a fragile device, especially the LCD screen. Unfortunately there's no fix for a cracked LCD screen - you'll have to repair it and get the screen replaced. If you obtain the proper parts and equipment, repairing your own iPod is within your grasp.
