MTU of a network

Last thread, i mentioned that one of my friend reduce the MTU size to enable MSN chatting when he is using IzzI to acces the internet. Below is what i get from Wikipedia about MTU:

In computer networking, Maximum Transmission Unit (MTU) refers to the largest packet (size in byte) that a communications protocol is able to pass onwards.

High MTU: Higher bandwith efficiency. However, for high MTU set for a slow interface, can block-up the interface and cause lagging on other packets.

Low MTU: Increase the number of data packet, which increase the routing decisions of a routers. Thus, slow up the communication.

I found that, if i can settle the problem by setting the PPPoE connection to static connection, then i should reduce the MTU. This will actually slow-up the whole network. I experiment his method by setting the MTU==576 at home, and online using a laptop and a desktop at the same time. I found that both of my PCs' connection are slow, and get disconnected quite often.

When i switch it back and using my own method (static PPPoE), the connection is faster and i'm able to play online game smoothly (althought there is a ~1 sec lag).

So to my point of view, to have the home network connect to the Izzi's terminal with a router. It is better to set the router to connect using static PPPoE and maintain the MTU==1400.

Connect router to IzzI wireless modem

My router model is D-link 624 (i know, its a bit out, is a discountinue product...)
This is how i succefully connect my router to IzziPro terminal.

1. I access my router UI through http://192.168.0.1/, and change the unit IP to 192.198.0.1.
2. I set my router to PPPoE access with the my izzi's username and password.
3. Set a static PPPoE IP range from 192.198.0.2 to 192.198.0.254.
4. Enable the DHCP of my router.

and, that's it. I'm able to connect a desktop, a laptop and a PDA to the router and online, and MSN chatting through izzi's network.

nice to share ^^

iZZi Wireless Broadband

Try out the IzziPro yesterday nite.
My area is Bandar Sri Damansara, and i stay at 5th floor.
The signal strength stay within 50-60% only.
The agent told me that their Kepong tower will going to operate by 15th Sept, which is today. He mentioned that the signal should be ok after 15th of Sept.

Even the signal strength is within 50-60%, the downloading speed is quite stable at 380++kbps. I surf the net whole nite from 8pm - 1am in the morning, the line din get disconnet. But, when i tried to play online game, there will be a 1-2 sec lack.

This is much more better than Maxis wireless broadband that i used before Izzi. Maixs wireless is not stable especially during 8-10pm, keep on disconnect. Check the network type, it shown HSPDA connection, but dun even can chat with my friend on MSN. :sad:

I'm quite satisfy with Izzi and plan to stay with this wireless broadband. However, i would like to know, how am i going to connect it to a router so that the network can share within several users at home?

I'm using a D-link router, i'm now able to surf the net, but cannot sign-in MSN. Anyone can help me on this??

My New Nokia N76

HEHEHE!
Wanna share with you all my new Nokia N76.
It really looks great: Slim & Stylish.
I bought the phone at the price of RM2073 @ Sungai wang.
The original package come with a free Nokia Headset & 512M micro SD.
At first feel like wanna upgrade the memory card to 1G, but the salesman wanna extra charge me RM70 which i think is quite expensive, so i din take the offer.




Quality of the sound & speaker quite good.
The speed of applications is up to satisfactory, everything start up at a just nice timing.
Camera response is fast, but this phone is dun have a Carl Zeiss's lens, photo quality just so so if compare to N73.
Web browsing is quite convenient coz can rotate the screen to view more text lines at one time.
Will share more experience, as i just starting to explore this phone.

For me:-
Outlook: 9/10
Value: 7/10
Applications: 8/10

PS:-
For those who having problem to access the internet (wap) or sending/receiving MMS with you new nokia handphone (even after you have already save the settings from your service provider), i have a tip here for you.

SYMPTOM: When trying to send MMS, Error code display: Packet data not allowed.


1. Go into the main menu
2. Tools
3. Settings
4. Connection
5. APN Control (Access Point Network Control)
6. Waiting for the phont to retrived your SIM content

If there is notes saying: Retrictions activated,

7. Options
8. Deactivate Restrictions

The phone will asked for your SIM card PIN2 code.
For Maxis's SIM, by default is 1234.
If it is not, you can call your service provider to get the code.
Dun try to guess too many times, the phone will block the PIN2 code, and ask for PUK2 code, which is even more troublesome -.- !
