Digi 150 Infinite YouTube Buffering Issue (Video)

Digi Postpaid 150 Infinite serves me well. However, there is one issue that I am facing right now – buffering issue on YouTube playback. The Internet connection is okay. Everything is performing as it should be like file downloading, web browsing and other… Just YouTube is hanging here and there for no reason. Feel free to check out the video below to find out what I mean…

Solve intermittent network connection issue – ping request timed out

There are 2 networks in my lab environment. 1 test network and 1 general IT network connection. Test network is used for communication between test server, PQIUHC and UUT – for all the testing purpose. Test network is an isolated network. On the other hand, general IT network is used to connect to all other networks such as Internet, other lab or factory network. Test server has 2 NIC (1 connect to test network and 1 connect to general IT network)

My customer reported he failed to connect to test server from his UUT. Network failed intermittently. The simple way to test network connection is using command prompt to test it. Key in ‘ping -t testserver‘ (replace testserver with your IP) in command prompt. In normal condition, you will get ‘Reply from testserver: bytes=32 time=1ms TTL=125‘. Else you will get ‘Request timed out‘ if the server network is totally out of service. However, sometime you get reply from it and sometime don’t. This is what we call intermittent network issue.

There are many factor that can cause this issue to happen. Hardware might the one that causing the problem but very less percentage unless your hardware is very old. Another one is caused by software. Finally, human’s mistake. Most of the time, it is caused by ourselves.

For this case, it is caused by human error. Somehow, there is cable from general IT switch link go to test network switch. Therefore, whenever PQIUHC or UUT want to talk to test server. They will face problem to connect to test server due to there are 2 routes (test network and general IT network). So intermittent network issue will happen. Only 1 route is allowed in this case. All we need to do is unplug the cable between these 2 switches and everything back to normal again… πŸ™‚

Foscam FI9820W in the house

Yeah… I got myself an Internet protocol camera or IP camera for short. IP camera is totally new to me. Took me several days to study it. Narrow down to 2 megapixel 720P HD pan & tilt H.264 network cameras that I prefer ~ D-Link DCS-5222L and Foscam FI9820W. Not much review for these IP cameras. Foscam FI9820W is known to have issue on low light environment ~ picture / video quality is not as bright as older Foscam IP camera models. But I ended getting Foscam FI9820W too because it is cheaper than D-Link DCS-5222L. Will study more about IP camera and get a better one in the future when needed…

Celcom Broadband Mobile Internet Review

I started to use Celcom Broadband since I got my very first smartphone ~ HTC HD2. That was Celcom Broadband Basic with 384kbps. Got upgraded to 512kbps after few months. Then I downgraded to Celcom Broadband Entry on Voice with 384kbps connection speed only but cheaper price. Then it changed name to Celcom Broadband mBasic. And once again speed was upgraded to 700kbps.

Celcom Broadband Mobile Internet is my backup Internet access at home and primary when on the road. There are 4 Celcom Broadband Mobile Internet Plans currently ~ Celcom Broadband mLite, Celcom Broadband mBasic, Celcom Broadband mAdvance and Celcom Broadband mPro. All of them have the same connection speed at 3600kbps but have different bandwidth volume and price. Once again, I changed to the cheapest plan as I want to get 3.6 Mbps connection speed compare to 700kbps on old plan. How is the Celcom Broadband Mobile Internet performance? Let’s find out…

Free Innacomm W3400V WiFi Modem from TM Streamyx

Finally, 4 Mbps Streamyx is available at my place. I requested to upgrade early this year but no luck. I was still using RM 88 Streamyx 1 Mbps package then. Then I saw TM Blockbuster Deal which is a very interesting package for those who are still using the old separated voice and broadband plan like me. This combo package is a lot cheaper than my existing one. And you can have free call to all TM fixed line nationwide. Furthermore, you can get WiFi modem and cordless phone for free too. Isn’t that great? (Note – minimum 12 months subscription period is required. Not an issue to me at all)
