Try A New DNS Server With A Fast Internet Connection.
When you type an address such as lifehacker.com.au into your browser, your computers uses DNS to look up and translate that name into a computer-friendly IP address. Sometimes, though, the servers your computer uses to look up that information can have issues, or go down entirely. Check out our guide to finding the fastest DNS servers for more information. If your default DNS servers aren’t having problems, then you probably won’t find too much of an improvement with an alternative server — but it might speed up your browsing by a few milliseconds, at least. One reminder: if your provider offers unmetered browsing for services such as iView, be cautious when changing DNS details, since this can mean those services are metered and will count against your download allowance.

Wireless 3g Router More Security Application
The Security market is arguably the largest M2M segment to date, primarily with the adoption of wireless technology based on antiquated analog cellular and proprietary data networks. Most of these security applications have been designed to eliminate fixed line services to transmit alarm information to an alarm company. But, the shutdown of the analog networks in 2008, coupled with customer demand for higher value services including video monitoring is driving rapid migration to flexible digital network approaches.
According to ABI Research, the North American market for home security systems will reach almost 10 million devices by 2010. However, the real growth in Security will shift to digital wireless as the preferred network technology as the legacy networks are retired and new security applications drive the bandwidth requirement far beyond that supported on those older networks.
Beyond basic alarm monitoring, new capabilities are being added to enhance and improve security solutions. The use of video and still picture transmission allows alarm and security companies to view a location, in real-time, prior to taking action. This allows false alarms to be disregarded without incurring the cost of going to the location as well as avoiding false law enforcement dispatch. And, user interaction with home or business security systems, via any mobile device, will allow for notifications to a mobile phone as well as remote user control.
Sometimes, you may have the same trouble, A 3G Router Main Cause and Solution:
|1||cellular network 3G/4G low signal in the site||try to move to other place to test if can get better signal|
|2||antenna not gain good signal||try to change another antenna. E-Lins antenna is world-wide use, please ask for dedicated antenna or get dedicated antenna for your carriers from the local antenna sellers.|
|3||SIM card service issue||try to replace another sim card to check|
|4||Carrier service issue||try another carrier to test|
Example for E-lins hsdpa router :
At H685/H820 router, set the SMS feature as picture above, but when we try to send SMS to H685/H820 Router via phone number 2012, the phone number 2012 cannot receive any info from the H685/H820 router.
Main Cause and Solution:
|1||The Router SIM card SMS service is not working||try to check the SMS service via mobile phone. Use mobile phone to confirm the SIM card SMS service is working before use H685/H820 Router SMS feature|
|2||Setting compatibility issue||Uncheck the configuration of "Fix Error For Some Network". Some network need check this configuration, and some network need uncheck this configuration. Please try both for test.|
Not all VPN service providers are worth your trust. Some diligently log your connection times, dates, IP addresses, keep track of how long you're connected, and some even keep an eye on the types of traffic that you send through their networks while you're logged in. They'll tell you it's in order to make sure you're not doing anything illegal, or anything that would damage their network, but that level of snooping does kind of go against the whole purpose of a VPN, doesn't it?
The best ones keep as few logs as possible, and aren't interested in what you do while you're connected at all. Some don't even track when you're logged in or out, and even if they do have to keep some logs, they purge them periodically in order to protect your privacy. After all, the reason you pay for a VPN is for privacy and security, and if they keep their own data, they're the weak link in that chain. Here's are some tips on how to research a VPN and decide whether they're a good match for you.
