Wireless access to the Internet provide so much flexibility and break limitations on mobility. With the prices of wireless hardware continually decreasing, wireless networks are becoming increasingly popular in businesses as well as in homes. However, not many resources that help fix issues with these unpredictable wireless connections exist. Sometimes, the solution might be extremely simple, if only users are informed about it. The tips here will help you understand some common trouble scenarios in a WiFi connection, and assist you in tackling them.
Hard Reset The Router
This might seem to be an insignificant solution, but surprisingly, it does work sometimes! Simply try turning off your router, and switch it back again after a minute or two. If this doesn’t work, perform a hard reset of your router.

Or at least it will be in the next few days at the highly entertaining Black Hat Conference. This annual get together of security experts – on both sides of the fence – has become the place to reveal newly discovered computer and network loopholes and flaws. It’s usually to be followed by lots of nervous press releases from manufacturers and software companies, either promising fixes, or claiming the security issues are non-existent or irrelevant.
This one, reported by Engadget and uncovered by security researcher Craig Heffner, highlights a long-standing problem with wireless routers known as DNS Rebinding. Heffner developed a tool that managed to crack open more than half of the thirty routers it was tested on, including popular models from the likes of Belkin and Linksys. Internet and network traffic passing through hacked routers can be intercepted or redirected, potentially allowing remote access to files on a user’s computer. Although the full extent of this vulnerability has yet to be revealed Heffner says there’s a lot users can do to protect their routers. This includes changing the setup menu’s default password and IP address, which will help until the manufacturers come up with a more permanent solution.
The latest routers, security suites, and software patches can help protect your PC against today’s ever-more-sophisticated Internet attacks.
These security tools are easy to install, easy to maintain, and provide the average PC user with basic protection against viruses, botnets, Trojans, rootkits, and other types of malware.
Keeping your PC secure goes far beyond convenience it can protect you against significant financial loss. That’s not hyperbole: according to the Internet Crime Complaint Center’s 2009 annual report (available from the IC3 site), Internet crime losses more than doubled through 2009 to more than U.S. $559 million!
But it’s not hard to provide a reasonable level of basic security for any PC. For average PC users, the basic rule for keeping PCs secure has not changed keep it simple, keep it up-to-date.

Why upgrade? Chances are you have bought something online with a credit card, used internet banking, or dealt with confidential information on your computer. If you use a wireless router with anything less than WPA2 encryption, your information may not be as secure as you think.
“WPA2 security is definitely worth the modest amount of effort required to set it up. The original WPA security standard can be cracked with relative ease unless you use a passphrase that is longer than 20 characters and is not merely composed of words that can be found in a dictionary.” [Quote from the PC World article: Wireless Tips: Your Wireless Network Needs a Security Update]
1. Check current devices for compatibility. Your router and wireless network card may already support WPA2; Google your devices and find out. If they do, download the latest drivers for your wireless network card and update the firmware on your wireless router (very easy to do, but follow the manufacturer’s instructions carefully). More »
The following guide allows you to wirelessly sync an iPhone with Amarok in Ubuntu 7.10, including adding, editing and playing songs and playlists.
Note :- it requires a jailbroken iPhone.
Step1 :- Set up the iPhone
On your iPhone:
Click Settings → General and set Auto-lock to Never. This will ensure the iPhone keeps the WiFi connection open.
Click Settings → WiFi and select your WiFi network. Click the Static button and change the IP Address to something outside the dynamically assigned range of your network. For example, if your wireless router normally assigns 192.168.1.1 – 192.168.1.5, try 192.168.1.10. This will ensure your iPhone is always contactable at the same address for syncing. More »
