The worst thing is the DSL is very unstable (blinks frequently) and disconnects very often and most cases i cant even work for 5 minutes.

I realised after a frustating night, i heard the phone dial tone and i hear the `crack crack` line noise  in the line. This despite having used the ADSL splitter.  Be careful that most splitters which are chinese made are not good quality and may amplify the line noise. After consulting with phone technicial i was asked to replace the phone line and the new splitter.

If you face any problems like this you may need to check out for the faulty adsl splitter or a telephone cable.

Troubleshooting

To successfully fix the problem follow the steps.

1. Take out your phone cable out of modem and plug into your phone and see if you can hear phone dial tone properly.  DSL lights may not blink or become unstable if you have faulty phone line or have lot of noise in it.

2. Double check the ADSL splitter and this is the most common cause of internet problems. Go to electronic store and buy it and see if that works. It just costs about  $1 and may well solve all your problems.

3.  To check the statistics of the connection, login to your modem/router using http://192.168.1.1/ or http://192.168.168.1/ using your login and password and check the DSL connection statistics

If you see lot of super frame errors, then surely the packets are getting lost in the transmission.  Below is a very short guide on the numbers involved.

SNR Margin (Signal to Noise Ratio Margin) – You have to watch out for SNR Margin (usually in 20′s) and if it is too low you may get disconnected often.

Line Attenuation – It measures loss of signal over distance and its value in 20′s means excellent

SNR Margin

A higher signal to noise ratio will result in less errors.

  • 6bB. or below = Bad – experience intermittent synchronisation problems.
  • 7dB-10dB. = Fair
  • 11dB-20dB. = Good
  • 20dB-28dB. = Excellent
  • 29dB. or above = Outstanding

Attenuation Rates

Attenuation is the loss of signal over distance. Unfortunately, dB loss is not just dependent on distance. It also depends on cable type and length of the cable, including location other connection points on the cable.

  • 20bB. and below = Outstanding
  • 20dB-30dB. = Excellent
  • 30dB-40dB. = Very Good
  • 40dB-50dB. = Good
  • 50dB-60dB. = Poor and may experience connectivity issues
  • 60dB. and above = Bad and will experience connectivity issues

    Nowadays sharing photos online has become so common among many people and most photos come out of camera device have huge file sizes because of more resolution and megapixel. The more the resolution and megapixel the larger the filesize. The fact is you wont even need the photos with the bigger size (> 4mb per photo). Imagine you have about 10 photos you need to upload and each photo is 3mb is size. It consumes a lot of time during upload

    The way to go is shrink any photo so that it is less than 1mb and without losing quality. Most photos are JPEG format and you will need to shrink the photo and keep width of less than 1000px which would obviously bring down the filesize.

    How to shrink

    1. Download Irfanview photo viewer. It is FREE!
    2. Type CTRL+R or resize from menu.
    3. Enter the resolution within 1000px or if you want even less size try 800×600 resolution.
    4. Save as desired fileformat JPEG. Dont forget that JPEG is the best format for photos.

    Thats it! You will have less size and you will find pretty easy to upload many files.

    Finally, to get the best protection against viruses and internet attacks, make sure you buy the antivirus software that comes with firewall like Kaspersky Internet Security. Just my 2cent advice.

    i am not a pro when comes to video editing and conversion. I am sharing here some of the easy tips on converting large avi file to dvd format.

    My situation:

    I had a 3 hour very large home video (about 30GB file size) in avi format from my Sony Handycam in miniDV cassette.

    What i wanted

    My goals were to transcode/convert the 3hr video from miniDV cassette and compress the video in such a way to get accommodated it on single 4.7GB dvd (not in multiple dvd disks) without compromising the video quality and very importantly playable in most DVD players.

    I searched all over the web on how to convert the video in avi format and write to DVD and the answers were hard to find. Very soon i found the answer was just around the corner.

    Answer:

    The answer is NERO DVD writing software. I had a version 6 that i owned and never knew it would do such a wonderful job. I imported all video clips through i.Link cable (Firewire port) and the total size of the video is about 30GB. The software prompted me to automatically to fit the video to available dvd space and viola! Its done! In my case it took almost 2hrs to write to DVD and the effort was well worth it.

    Conclusion:

    Once everything is completed, i noticed that by lowering the sampling rate of video, the whole video was compressed and got inside single DVD disk. The whole file size was only 3.2GB and the quality of video was really good when i had a look on having played in a DVD player.

    NOTE: You must only use DV/Firewire port along with i.Link cable to get best picture quality. Dont use USB port to import video as it would get more noise and the quality of video would get degraded significantly.

    While installing NERO suite you have install Nero Vision express which is very important to do this video task.

    - Negative balance
    - SIM not activated
    - Weak signal strength.

    All of them dont apply to me

    This is very disappointing and quite frustrating experience!. I am not sure how to fix this problem.
    Please post here if anybody getting the same trouble and if possible a solution.

    Update: It appears to be the internet has now started working. I think it was activation problem and they need to come to your home for verification (postpaid). And after that i was able to connect to internet without any problems.

    [The conclusive paragraph is known the “boilerplate” and can contain no more than 2-3 lines. A short "about" section, providing independent background on the issuing company, organization, or individual. Here you should explain future aspects, your or aim in meeting the current market or success. In general what you intend to do achieve.]
