Tech And Leisure..

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 ;)..


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:

Since a lot of visitors are inquiring about error 619, I thought that my previous post may not giving you a comprehensive understanding with regard to ERROR 619. Indeed most of the hits to this blog are from those who are searching solutions to this error. So here we go again (please note that this troubleshoot is done using Celcom Mobile Broadband):

what does error 619 mean?
This error indicate that the connection to certain network is timed out usually due to
1. Network Congestion/Poor Signal Strength
2. Port error

Root Problem:
1. For network congestion and poor signal strength, in the case of Celcom Mobile Broadband, it may means the 3G or WCDMA network which you are trying to connect may be congested or probably due to your location which is too far or beyond the range of the Celcom WCDMA transmitter tower.

2. For port error you can refer to my previous post: http://amrymr.blogspot.com/2009/03/error-619-connection-to-remote-computer.html


Solutions:
1. Please make sure your device detect Celcom WCDMA network and at least there are 3 bars of signal strength are available. Below than that may cause your connection being frequently disconnected or worst, no connection at all.

2.If the error occured when your device attached to WCDMA network, the best bet is change your device network setting to GPRS only. A thing to note here is that whenever you want to choose connection type please make sure you use GPRS only or 3G/WCDMA only. Do not use GPRS preffered or 3G/WCDMA preffered because it may effect your signal and connection stability.

3. Sometimes your computer confuse itself by mistakenly arrange devices within a same port. This may happen when you unplug your modem improperly. Rebooting your computer will repair the mis-managed port.

4.Sometimes your modem will not work (due to file or installation corruption) on the pre-installed software such as mobile connect lite or mobile partner. In a rare but possible situation, the dialing software got bugs. Try to download the latest version of your dialing software from the internet such as www.business.vodafone.com (for hua wei and vodafone brand only).

5.If the connection is still failed, you need to do a manual connection. In brief, I try to explain it here:

Yes, avoid using or upgrading to Windows XP Service Pack 3 specially if you are a heavy user or rely mostly on the wireless internet connections such as wifi and cellular based ISP. Recently a Celcom Mobile Broadband subscriber consult me with regards to his internet problem. He live somewhere in PJ and he said that he suffer a very unstable and slow download. The problem is that he was able to connect to the Celcom 3G/HSDPA network, but whenever he try to access to a website error "page cannot be displayed" will pop up on his browser`s screen. He said that this is the case since a few months already. He even try to PING yahoo website but it seems that the connection was timed out.
Since this subscriber already face this problem quite a while, I suspect that this is not the normal Internet service failure. However I did asked him since when he realized that he faced this problem, and he said that previously his internet connection was OK. However a few months back he upgraded (Operating Systems) his laptop and his PC from Windows XP SP2 to Windows XP SP3. According to him since that day, he can only surf the internet by logging into his company VPN network from his computers.

A quick search on the internet reveals a shocking discoveries. This is not an alienated incident. There are many other cases out there similar to this unlucky Celcom Mobile Broadband subscriber. XP SP3 installation will not only install the upgrades to your Operating Systems, it will also install unnecessary system registry which will create havoc on your root system. For the time being, it is confirmed that the unwanted registry only effect wireless internet connections. Meaning that Fixed Internet Connections got no problem with XP SP3.

If you are one of the unlucky one who upgraded to XP SP3, the solutions available are; 1st by further upgrading your OS to Vista or downgrade your OS to XP SP2, which in the case of our friend here form PJ, duly solved his problem. 2nd continue using XP SP3 and wait untill Microsoft provide a patch, which most of us will love to hate ;)

Have a good surfing day!!
