Before buying a storage device USB Network Adapter, these three precautions

ICS Computer storage of office and home networks has proven to be effective to avoid unnecessary duplication of files, video, mp3 to reduce access to multiple computers and laptops. Using a central repository of storage, the files will be entered once and streamed from there, or need, at any time and from anywhere on the internal network, copy, even on the Internet. A convenient way to share files, printers, home network through the useMulti-Port USB or Universal Serial Bus, Luggage network card.

USB adapter or network storage enclosure is a simple serial bus hub, which on the one hand, several ports for hard drives, printers and possibly other USB devices, and on the other side of a TCP / IP is the standard Internet connection . You can "share", then the various Universal Serial Bus devices on your home network policy.

Wireless Network Detector

Many network storage enclosure is currently offered byto promise more than one supplier, the easy sharing of USB devices connected through the home network. Before you buy a network adapter Universal Serial Bus storage, make sure you understand what these "network sharing", and all the reserves that come into force. Understanding this before you buy, you will be able to install and use their functions immediately and without delay or frustration.

The three reservations in dealing with the Universal Serial BusNetwork Storage Adapter are: first, USB devices are not to many users at once, second, USB devices are used, even if developed in order to draw power from the bus can not handle too much power, and thirdly, the unit reformat your hard drive before it can be used within the network storage adapter.

Caveat 1: Only one user at a time from a USB device

USB devices such as printers, hard drives, cameras, neverdesigned to be used by multiple users at the same time. Unlike a normal network drive, in some network storage container, the user needs to access a specific device, and the dedicated connection must first be determined before the drive or device can be used. What makes a further step in the process, and for some purposes, the Universal Serial Bus "shared" device really useless. Not all USB storage enclosure network have this requirement. To checkfirst.

Caveat 2: Connected Universal Serial Bus devices can not be too much power

Many devices require power from the Universal Serial Bus USB port itself. Hard drives, especially a lot of energy. So, especially if multiple hard drives to get a USB network storage enclosure, both hard drives with its own power supply from the network, or ensure that their power to the bus terminal are manageableand is small enough.

Caveat 3: need to reformat the hard drive to be used in a USB network storage enclosure

This can be a nasty surprise when you take the external hard drive that you are using Windows, install it in a cabinet network, follow the instructions (so slowly we suggest the data may be lost), and find all the data on your hard drive disappear. Similarly, because the formatting of hard disk drives that use thesecompatible with Microsoft Windows, remove the disc from its case and the insertion into the socket on your computer or netbook not receive your information.

Troubleshooting network problems Wireless

With the emergence of wireless Internet connections, there are people with good connections to the Internet. Workplaces, restaurants, schools and department stores offer free Wi-Fi access to people, and, above all, these people also prefer wireless connectivity in their homes, enjoy the comfort that connect to the internet via their desktops, laptops or even their high-end mobile phones anytime, anywhere.

Every good thing has a downside andWireless is no exception to this rule. Wireless network problems are sometimes experienced by users. Surely the inability to access the Internet to counter a person, especially if you are in a situation where urgency is at a higher level.

Wireless Network Detector

Here are the most common wireless network problems and some suggestions that may be useful when considering these types of problems:

• No links found

IfIt is likely that you have this case, make sure the wireless switch is turned off the device "on." If it is already on and you have not found any connections, check your position (if it is covered by a wireless network).

• Connections Suddenly Out

What is more annoying than in the middle of sending an important e-mail to your boss off? The signal is suddenly want to throw your wireless router to feel. Whenparticular wireless network problems like this, try to cool the calm and control your cable modem or DSL. Normally in this situation, the problem is not with the router, but it's the ISP that went down. In this case, contact your service provider.

Another possible cause is a conflict of IP address. In this case, try rebooting your wireless router to get a new IP address.

• Loose connections

There are two possibleReasons for this wireless network. The first is that your position or place, or too far from the router in an area where one with too much interference, like cordless phones and cell phones are. Solve this problem by simply moving closer to the wireless router. Another reason is that you can have too many people attacked, or the network to download large files too. Solve this problem by limiting the number of usersable to connect to the network and enable security.

There are just some of the most common problems of the radio network that may be encountered and their solutions.

7 Tips for Easy and fast creation of a secure network home!

Do you have a secure network at home with the use of WI-FI?

In other words, access to the wireless network to the Internet without worrying about hackers, viruses and theft of wireless signal cares? With a home network safe requires more effort and education than just buying a wireless router (s), it connects to the Internet and access to surf while praying no one will hack! What many users do not realizeWhen you configure a home network is that if you buy a router and setup password, by default, the network is not secure.

Wireless Network Detector

If you use Internet service providers (Verizon, AT & T, etc.) will send a broadband modem to other computers on the Internet, wireless (Wi-Fi) allows, it is likely that you're not sure, unless someone on the Internet and Modem installed security configuration "property."

In the new "social networking" age, it is importantAware of the Internet threats that lurk, and how to protect your personal information and data from a home network safe from thieves. Did you know that there are tools and software that exists that allows a person to your home wireless network for steal a connection with him, "crack" the key (password) and what they want from your computer (including credit card numbers, financial, passwords, images and other sensitive dataetc.)!

Let's look at how to create a secure network at home and feel safe - "safe" surfing the Internet.

1). In your broadband (wireless) modem or wireless router, the default name and password for the admin panel of the router (used to modify all settings of the router / modem) access.

Note: The default name is usually "admin" and password is specified in the documentation (or disk) by the manufacturerequipment

2) Always use encryption (password / key), to truly secure a home network.

WEP (Wireless Encryption Protocol) and WPA (Wi-Fi Protected Access), are the two most common types, with the EPA to "crack" more difficult than WEP, WPA, then a better choice for safety.

In addition, it is always better to have a completely new and different password (key), at least every 30 days, to safeguard and protect your home network. Passwordshould be to "guess" difficult - in other words, with a mixture of symbols, alpha / numeric characters, uppercase and lowercase letters and at least 8-14characters if at all possible.

Note: An example of a strong password is: "1mypasswordx90544z" or how about: these are harder to guess passwords using password-cracking software "Tektime1 p0rt $%%".. (Do not "easy to remember" passwords, such as passwords that include your name, the name of your children (s), date of birth, your way will be made;etc.)

3). Turn on your wireless router or DSL modem, if you do not have access to the network.

For example, if you go to bed or if you are not home it is best to disable your Internet continues to act as a protective barrier for your home network secure. As intruders, trojans, etc. cause damage to your computer or Internet connection if not send a signal? You're right ... can not!

4). Disable Service Set Identifier transfer to your modem / router.

Otherwise, as "SSID" is known for the name identifier of the device by the manufacturer. For example, the D-Link router that will "Dlink" as the SSID, while the Netgear router made by "Netgear", as well as the SSID. Turning off the SSID prevents the wireless home network to be in the list of "available networks", if someone seems to scan the area for wirelessTo connect networks>.

5). Change the SSID.

And disabling the SSID of the router, it is important to change the SSID, even if it does not seem due to the last stage where we have disabled. Changing the SSID will not prevent a secure network at home, but that hackers and spies out immediately what your router. You know what router is used, a hacker or thief more willingto cause chaos in the home network, especially if you are accessing the same name, password, and information management standards, such as the manufacturer has created.

6). A network firewall safe at home EVER!

Many firewalls, which can come into your router (hardware firewall) built cause various problems when access to the Internet. It 'best for beginners and novices to use a software solution, to learn the ins and outs of firewall hardware andtheir borders.

Firewalls can be created for the software (eg Trojan horse) to prevent a connection to the Internet without your permission, thus preventing unwanted transfer of data, personal financial information and other confidential information. Firewall prevents access outside your home network without your permission.

Note: A highly reputable software firewall solution, Comodo Internet Security. Feel free to look it up in your favorite search Engine. It's all free (the basic version), to operate very efficiently and easily (after a slight learning curve). I recommend it to all my clients and are not paid by Comodo in order to support them. It 'just a good program, try it!

7). Reduce the scope of the wireless signal.

A secure home network does not transmit a signal to the outside environment of the Internet user at home. So you should reach your> Wi-Fi signal?

Imagine you buy the "biggest and baddest" wireless router that you can be found from a retailer with a range of 1 mile! Wow, this is a long haul ... can be anywhere in the house that does not have a signal loss at all! Although this may be true, the truth is that you only have a signal range of the signal can be transferred into your house, and not necessarily outside.

This prevents thieves connection to the Internet (andHackers) on the possibility of radio waves received by the router or modem, then connect the signal would be virtually impossible, even by more experienced hackers!

Tip: One way to signal your area is less, switch to 802.11 g, 802.11 s, 802.11 or b. Consult the documentation for your router from the manufacturer, contain certain information.

Hopefully these tips will help you to create and sustain a secure network at home, and will not behave nightmares experienced by many people to protect the wireless network is not the face!

Always remember that an ounce of prevention is worth a pound of cure!

Until next time,

Calculation happy!
