Hackers are now targeting your router

Many service providers give you a cable or DSL modem with a built-in router. These steps still work for combined units.

First, let’s protect your router. There are three simple steps.

1) You need to do a geeky thing called “updating the firmware.” Every router maker’s process is a little different, but here’s the basic outline.

First, find your router’s program on your computer. Fire it up and it should automatically find your device.

If you don’t have a router program, look up your router’s manual online and see what the device’s IP address is.

Type the number that corresponds to your router’s address into your browser and enter the default login password found in the manual.

While you’re in the router settings, make sure to change the default login password that came with the router. There should be a button labeled “update firmware.” Hit that and go through the process. That will, at least in theory, provide the company’s latest protection. (Bonus: It might increase your device’s performance, too.)

2) Make sure you turn on wireless encryption and provide a strong password. Strong passwords are a pain, but for your home network you just have to enter it once for each gadget. Just remember to keep it written down in a safe place in case you forget it.

Because computer manufacturers want to make our life more complicated, we are confronted with another blinding array of complicated acronyms when it comes to choosing what encryption to set. Look around for an option to secure the network using WPA2. It’s the best protection right now.

It’s smart to put in a long and complex password. Again, it’s a pain, but it will make your network secure from anything but industrial-strength attacks.

3) Finally, take your router offline and make it invisible to passers-by. In the settings, turn off SSID (or network name) broadcasting. This keeps your network hidden unless you know the name. Be sure to change the network name to something that’s hard for someone to guess.

Now your router is safe from attacks. Let’s save you some money and improve your Internet service.

Check your Internet speed using the handy testers available at Speedtest.net or Speakeasy.net. Do it with your computer plugged in to your modem with an Ethernet cable. Keep notes on the plugged-in speed.

If you are one of those lucky folks who have competing Internet and cable providers in town, the first step is to call your cable company and try to negotiate your bill down. If your download speed is significantly slower than what’s promised, start off giving them heck about that.

For cable companies, call and say you’re looking at an offer from a satellite provider. If you have a cable modem for Internet service, say that you’re looking at a cellular, satellite and DSL offer.

Next, make sure you have the fastest modem available. Most cable customers are paying a per-month cable modem rental. If that’s your deal, make sure you’ve got a DOCSIS 3 modem. Get an upgrade if you don’t.

Finally, there’s your wireless router. This gobbledegook nomenclature is a pain, but you have to make sure you have one that uses the 802.11n standard. If it’s 802.11 b or 802.11g, you should know those are very old standards. The cost of a new “n” one will really be worth it in terms of speed.

If you are buying a new router, consider whether you’re going to be getting a new computer or tablet soon. If so, consider paying a little extra for the very newest standard or 802.11ac. That won’t help most older computers, but it’s a speedy step forward for routers. You’ll be glad you did as you get new devices that adhere to that standard.

Keep your kids safer on internet

When you turn on Family Safety for a child's account, monitoring starts automatically. Family Safety sends regular activity report emails to your Microsoft account, summarizing how much time the child spent on the PC, the websites they visited, the games and apps they used, and the terms they've looked up in search engines like Bing, Google, or Yahoo! Search.

The email summary gives you a lot of info about your child's PC activities at a glance. But you can always delve into more details and change permissions and other settings based on the activity info by choosing a link in the email report to view the report online. You can also open the report from the Family Safety website.

Here's how:
1. Go to the Family Safety website and sign in.
2. Tap or click the name of the child whose report you want to see, and then tap or click Activity reporting. 

Make sure activity reporting is turned on.
Summary details:
The top half of the Summary page shows info about the websites your child has visited recently, and any web searches they've recently performed. The bar chart of most popular websites indicates the top five sites they've been to and how many pages within each site they've looked at, but doesn't show how long they might have spent on each site. To see a complete list of every website your child's visited in the last week, tap or click see all above the chart. All of the web addresses and search terms shown on the Summary page are also links that you can tap or click.

The bottom half of the Summary page shows info about how much time your child spent on the PC, the apps and games they used most frequently, and any downloads they've made from the Windows Store.
Web activity

For a complete list of your child's Internet activities, you can also tap or click Web activity. This page shows all of the sites your child visited or tried to view, including sites that Family Safety considers "suspicious" or potentially inappropriate. TheAction taken column indicates whether Family Safety allowed the site, or blocked some or all of its content. The Categorycolumn shows the website categories as determined by Microsoft, but you can dispute a site rating if you disagree. Use the buttons in the Change settings column to allow or block your child's future visits to a particular site.
PC activity

For a breakdown of your child's overall PC use, tap or click PC activity tab. The Sessions section indicates when and for how long your child used the PC during the week. The Apps and games section lists each app or game that your child used, when, and for how long. The Action column also indicates whether your child was blocked from using a particular app.

File downloads from the Internet and downloads or updates from the Windows Store are listed separately in their respective sections. If your child downloaded a game from the Windows Store, and then played it for 45 minutes, that game will appear in both the Windows Store downloads and the Apps and games sections of this page.

Free Kall on your mobile and landline

For those who do not mind the annoyance of advertisements right in the middle of a conversation, a team of engineers in Bangalore has a free voice calling service for any part of the world. Termed FreeKall, it brings voice-over-internet-like services to those without internet access.

The idea, which was thought up in the dorm of M S Ramaiah Institute of Technology in Bangalore, was launched as a service last Saturday. Still in beta, or testing phase, nearly four lakh FreeKalls have been made so far.

"The response has been phenomenal. Our servers crashed about seven times and we had to bring it back up," said Yashas Shekar, a 23-year-old who cofounded the company with college-mates Vijayakumar Umaluti and Sandesh Eshwarappa. "On the flip side Sandesh, and Vijayakumar have not slept since Saturday," chuckled Shekar, a former Godrej Interio employee who shut his first venture, a web development firm, to concentrate on this startup.

The service, in some ways, is reminiscent of the trunk calls of the last century, except that the cloud infrastructure does the job instead of an operator. To make a FreeKall a user dials number 080-67683693 and the call is disconnected after just one ring. Following this, the system calls back the user, and an automated system prompts the user to dial the desired number. Lo and behold, the call is connected. The system can currently support 10,000 requests per second. If it goes beyond that, it will not be returned.

"I must say, someone has thought out of the box. This can be truly disruptive if it works out well," said Hemant Joshi, who oversees the telecom practice at consulting firm Deloitte.

FreeKall makes money by making people listen to advertisements. So, when the call is connected, the user hears an advertisement instead of a ringing tone. And at intervals of two minutes, the caller and the called party will have to pause the conversation and hear an advertisement for soaps, shampoos and the like.

For now, unregistered users can make calls that last three minutes. For those who register, the conversations can last 12 minutes. In about a month, there will be no limit on the amount of time a person can FreeKall. International calls will be possible in about a month, once legal clearances are obtained.

The company is aiming for 10 million calls a day in India and expects revenue of $30 million ( 185 crore) by the end of the next fiscal. It plans to take its business to Africa soon.
