Huawei HSPA modem Antenna
Sep 4th
Using Huawei HSDPA modem to access internet? Most of in home HSPA users use HSPA because they don’t have access to ADSL lines because no telephone exchanges nearby. So if HSPA signal strength is low in your area you might expected low internet speed. How ever most of huawei hspa dongles have a socket to plug in external antenna.
So you have a solution to boost your signal but don’t expect a huge boost from this method. Maybe you will able to get like 500kbps or so boost in your internet speeds but only if current signal strength is low and depends on provider.
If you cant find these antennas in your local electronics store you can try ebay. There are lots of Chinese sellers selling those.
Google DNS Implementing and Google VS OpenDns benchmarks.
Feb 28th
As I said on my previous post DNS is very important factor that directly affects your internet browsing. Google says this abouut the importance of the DNS-
Why does DNS matter?
The DNS protocol is an important part of the web’s infrastructure, serving as the Internet’s phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day.
Big G said that. Google lately introduced their own DNS service. Yes its the next step in the process of Googles Internet take over 
Nevermind. Currently the biggest out of ISP DNS provider is OpenDNS www.opendns.com Before Google introduced their DNS service I used OpenDNS because its way faster than my current ISP’s DNS. OpenDNS has many servers inside USA and many other in leading countries. So its very fast if you live in USA or around. But even in Asia for me OpenDNS is advanced for me because its updating instantly while my local ISP takes about 48 hours to update.
So this is not the time to talk about OpenDNS. Now I have configured my computer and router to use Google DNS system you can do the same read this guide- http://code.google.com/speed/public-dns/docs/using.html . I live in Sri Lanka both googledns and opendns doesn’t have servers in my country or neighborhood. So both services connect to USA servers (GoogleDNS only have servers in America with Level3 network OpenDNS got Anycast Routing Technology that Routes your DNS queries automatically to closest server available,). Lets compare this with Namebench DNS benchmark.
Yes its way faster than OpenDNS here is ping test to OpenDNS servers and Google servers-
Note that 208.67.222.222 is the ip of the opendns while the ip 8.8.8.8 belongs to googledns-
And DNSBench benchmark results-
All this tests shows that GoogleDNS better than OpenDNS for now. ITs your decision to move or not!
Introduction to DNS systems.
Feb 26th
What do you mean by DNS? Simple answer is Domain Name Servers. How they work?
Well the best choice to explain this is telephone directories. Imagine that you wan to call some one and you know his/her name but not telephone number. So you need a telephone directory to find his/her number. So you can flip the papers of the directory and search for his name and then find the telephone number you need to know.
DNS service acts same like the telephone directory in your home. When you type www.google.com or any web site address in your browser Internet service need to find the ip of the server where google.com situated. So your computer makes request to find the ip address of the google.com from DNS servers. So DNS servers gets the request and then forward us the ip of the web site you need to go.This process works inside of your computer network so you dont get any visuals of ips.
Typically Internet Service Providers operate their own DNS servers for their customers. They are automatically assigned to your computer if you not manually edit DNS options in your computers network settings. But you can change DNS servers if you like to get more accurate and fast web browsing.
Imagine if your telephone directory is old and un-arranged it takes more and more time to find the phone number. Like the same process the quality of your ISPs DNS server directly affect your web browsing speed. This doesnt means the downloading speed.Slow download and upload speeds doesnt mean your DNS bad.
Come again to the theory of the telephone directory. When you have un-arranged directory it takes more time but it doesnt affect the quality of the call that you make to other party. If you have well arranged telephone directory it takes seconds to find the telephone number but you gets the same quality of the call like previously said.
Bad DNS servers makes slight delay when you request for a web site.
In my next post Ill explain how to optimize your DNS system to be more accurate and Ill do a brief benchmark of newly introduced Google DNS system. SO wait……………….
Activating Voice Calling on Huawei HSPA modems
Feb 26th
On my previous post I wrote about how to unlock huawei modem models. So there is another great option in most of Huawei new HSDPA modems (In cheaper models too) . Today I will show you how to actviate voice calling feature hidden on your huawei medem. I have used E156G and it works on this models too. Huawei E156 / E156B / E156C / E156G
First of all you need to download this piece of small software to check if your modem suports voice calls ( No matter if the feature disabled in factory settings we are going to activate it. So its worth to check)
Download it here- http://www.dc-unlocker.com/downloads/get/03FpJrhM
And run it after installing.Make sure to exit Mobile partner otherwise the software wont detect the HSPA modem. And after opening it click scan. it will then display the details of the plugged huawei modem like this-
