VLBDC error anybody?!!

This morning I received an email with an error which I never heard/know before. Anybody out there who were "special" enough to face this problem? Frankly speaking, since I subscribed to Celcom Mobile Broadband, I didn't encounter any problem with their service (except in a few occasions where the error 619 demon 'surface' and caused my connection to transform from BROADBAND service to SUPER SNAIL BAND).

Scenario:
A subscriber try to do connections to the internet, and.....the browser will automatically directed to this webpage www.vlbdc.com. Thinking that his homepage maybe accidentally changed, he tried to open another website. To this subscriber horror, it seems that he cannot even open another page because every time the subscriber typed a web address and hit enter, automatically it will be directed back to this haunted www.vlbdc.com

Solutions:
Since I never face this problem before, I don't have any concrete answer to this problem.. Generally, if the subscriber are able to open the vlbdc.com site, that means the internet connection is OK. The most probable answer is that the subscriber computer was invaded by a virus/malware. I did try to open the website myself. Here is the screenshot:
A quick WHOIS of this website:
This website is registered under a company located at Shanghai China (75.125.118.191). So, if its so happen that your computer was invaded by viruses/malware, then you know exactly what you need to do. Update your Antivirus and make sure your firewall is activated. Don`t forget to delete all your browsers old temporary internet files and cookies. Go to my computer, right click on drive C and go to disk clean up. Clear everything. Then repeat the same procedure to your other drive. Reinstall or better upgrade your dialing software and modem driver to the latest version. If still failed, try to do System restore. If everything has been done but you still get the same error, then maybe its time for you to reformat your computer.

P/s: If you happen to be the victim of this vlbdc.com error, please give me the full detail so that we can find the best solution for it.TQ

MOBILE CONNECTION IS NOT POSSIBLE

Posted by Mr Amry | Posted in , , , , , | Posted on 12:39 AM

Its almost 2 months since the last time I updated this blog [ I took a long leave :) ].

Last weekend I have a training/meeting with ZTE personnel. For those who does not know yet, ZTE currently is the main modem distributor for Celcom Mobile Broadband. They supply ZTE K3565-Z (Same spec with Huawei or Vodafone K3565). Same product, but from two different distributors. Both modem are using Vodafone Mobile Connect Lite as a dialling software and both a made in China products ;)..

(You think that this is a Vodafone product??!! Naahh..its ZTE or HuaWei. pls dont be fooled by the logo hehe )

Based on the training given, it seems that among the most common problem faced by those who are using this modem on a Celcom Mobile Broadband network is they frequently face this error "Mobile connection is not possible". Due to my laziness, I just copy and paste it here for us to share the available solutions:

Ladies and gentlemen, familiar with this error? If your answer is a definite yess, then proceed with your reading..

Reasons
Known reasons are 2 at present, and all the possibilities below due to the Windows OS problems or the compatibility.
1. As the pop-up window shown, other programs really occupied the device.
2. Network problems.
3. Devices Driver problems.

Way to fix
For 1, reboot the computer and try again. If no effect, uninstall VMC and install it again.
For 2, wait for a moment and try to connect again. If no effect, move to another place and try again.
For 3, right click “My Computer” and select “manage” – “Device Manager”, then check all the ZTE devices. Please ensure all the red selected ZTE devices works fine.
Please make sure all the ports and comm related to your modem is configured correctly

If not, install the device driver manually.

If you cannot install the driver manually, right click the device and select uninstall then scan the new device. The driver then can be installed properly.

The default path for the drivers of K3565-Z below (assuming that you installed your software in drive C):

C:\Program Files\Vodafone\Vodafone Mobile Connect\Driver\pccard\xp\ZTE3520

HOW CAN WE SPEED UP WIRELESS BROADBAND CONNECTION (PART 1)

Posted by Mr Amry | Posted in , , | Posted on 9:24 AM

The question that need to be answered here is that can we increase the speed of our Celcom Mobile Broadband? The answer is quite relative. In some ways, yes we can speed up the internet connection (be it download or upload). But in some other aspect, the answer is a BIG NO!!!

For better understanding, we must have a bird view on how the Internet user communicate with each other. During my early tertiary education level, I still remember my lecturer explained that there are several parties which form the communication convergence:

a) End user and the system which process the digital data into readable and understandable data. (In this case it is reffering to the individual and his computer set)

b) ISP provider or the Internet provider.

c) The internet itself

Of the three separate parties, you can only took control of the item a and item c above. For the Item b, you dont have the power to control it since it falls solely under jurisdiction of your internet service provider and you dont have privilidges to manipulate it.



A)End user and the computer system
  1. Better computer and machine specifications actually will speed up your internet access. Computer with big RAM ammounts and faster processing powers will process all the incoming data seamlessly without any lag. For example, loading a data intensive page such as youtube.com will be faster on the machines which is powered by an Intel Dual Core processor with a multi Gigabytes of RAM compared to machines which was powered by older Pentium 3 processor with a mere 64MB or 128MB of RAM.
  2. Upgrading your Operating system (OS) will also in theory will speed up your internet connections due to newer OS will take advantage of the power of the processor. Windows XP handles internet connection better compared to Windows 98.
  3. Apart from the computer specification and software, better modem specification also will give positive result for your internet speed. For example Huawei E160G USB Modem is better than let say the old Huawei E660 datacard.
  4. Using specific software for specific activity will no doubt will increase your internet speed. For example using a speciallized downloader software to download data or application from the internet will be the best options compared to the built in downloader function for Internet browser.

B) The Internet Service Provider
  1. I will not discuss further about internet service provider since subscriber are unable to control the flow or the process anything which are related to this matter.
c) The Internet or the Network which you are connected to.
  1. Under this category, there are several things that actually the subscriber can control.
  2. The Internet were born from several networks connected to each other to form the world wide web. Since there are millions of servers and computers connected, a system called DNS (Domain Name System) is used so that the computers and servers worldwide can inter-communicate among itself.
  3. DNS system regulates the address and route connection between the internet networks. Since DNS system was grouped into a tree-like hierarchy (there is a root, branches and other small group of DNS provider). Reliable DNS sytem can increase your data transfer rate to some extent.

DO CELCOM BROADBAND SUPPORT IPv6 INTERNET LAYER PROTOCOL?

Posted by Mr Amry | Posted in , , , , , , , | Posted on 10:30 AM

Recently a Celcom careline representative consulted me on a matter with regards to whether Celcom Mobile Broadband support the next generation of internet protocol IPv6.

The answer (eventhough may not be publicly announced by Celcom (M) Bhd) is affirmative. For the time being Celcom Internet network are based on the current standard which is the IPv4. Last year Ericsson was contracted by Celcom to provide a new networking flatform based on the All-IP architecture by deploying Ericsson`s Mobile Softswitch system. Reader can refer to this article for the full story {http://www.lightreading.com/document.asp?doc_id=149524&site=ctia}

As a result of the implementation of an All-IP core networking system, automatically it will also support IPv6 protocol per say. In laymen term for simple understanding, compared to IPv4, IPv6 have the upper hand over IPv4. I will only highlight 2 (actually there are several but for me these 2 are the most important), namely:

a. Support larger allocation for DNS system (IPv4 use a 32bits address and IPv6 use 128bits of address) and ability to accomodate the ever increasing internet traffic
b.More secure connections


Example: a diagram of ALL-IP core networks by Motorola inc

IPv6 addresses range from 0000:0000:0000:0000:0000:0000:0000:0000 to ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff(e.g: 2001:0db8:85a3:0000:0000:8a2e:0370:7334). For IPv4 the range is from 000.000.000.000 to 255.255.255.255 (e.g: 10.128.1.242)

POP3 AND IMAP EMAIL SENDING FAILED

Posted by Mr Amry | Posted in , , , , , , | Posted on 6:16 PM

Scenario:
A Celcom Mobile Broadband subscriber unable to send POP3 and IMAP E-Mail. However if connected to other ISP provider such as Streamyx or Jaring, the problem is not exist. In this case usually the subscriber are able to surf the internet and able to recieve Email. The only problem is when trying to send email using POP3 or IMAP protocol email.

Root Problem:
The IP which you are hooked to were blocked by your email provider server or even the intended or recepient email server. Why did the subscribers IP was blocked? There are several reasons but nowadays the most probable answer is that the IP was tagged due to spams (suspected spammers).

This is the downside of using dynamic IP where the IP were shared by multiple subscribers, and once one of the subscriber "missuse" or abuse the connection to send spams, then the IP will be blocked or tagged as spammers.

So how to solve it:
1. get your external IP address (you can get your from this e.g. website www.whatismyip.com or other online IP tools).

2.Once you get your IP, contact your email provider (if your email is your own company email, refer to your respective IT department) and verify this matter. If its confirmed that the specific IP was blocked or tagged as spammers, ask them to remove it.

3. If you are too lazy to contact your IT department, try to google "free IP". I bet you will find a lot of free IPs out there. Try several IP untill you found an unblocked one and are working fine for your connection. To change your IP, for internet explorer user go to Option>Tools>Internet Option>Connection> LAN setting. Here you can enter your desired IP. Try restarting your computer before attempting a new Internet session.




4.Sometimes if your email server request for DNS, I highly recommend these DNS address from openDNS (208.67.222.222 and 208.67.220.220). Eventhough Celcom do provide DNS server but the reliability is doubted. Previously the DNS used was of TM origin.

5.A few years back celcom IP 219.93.152.18 (during this time celcom were using TMNet backbone system) were listed by http://www.spamhaus.org and http://cbl.abuseat.org as spammer. Therefore a lot of email defender system automatically block incoming email originating from this IP address.

p/s: Apart from asking your respective IT department to release your IP, you can try to change your IP (as long as the IP is within the celcom IP range) to the one which is not blocked.
