Izzi Broadband (update)

From my experience, Izzi Broadband performance fluctuate heavily. From 250 kbps to 1024 kbps (almost). It seem, the ISP ‘divide’ the 1 Mbps line into half or even quater to support more customer who login at the same time while the tower can’t provide adequate bandwidth.

For those who read my 2 previous posts, you will notice that Izzi performance drop significantly at peak hour espcially weekend. Last night, I clocked my izzi performance as low as 250 kbps. But this morning (I assume most of izzi user still sleep @ 6.37 AM or preparing to go to work, except heavy torrenter), i manage to get 94 kBp.

And here is the perfect example, how slow izzi is when peak hour (I record this @ 1.19 AM, 12 Jul 2008 : Saturday)

13 kBps !!??!! OMG, this is not quater but 1/8 of the promise speed. Oh dear.

Bad ISP

According to Azureus Wiki :

The following is a list of Internet service providers (ISPs) that are known to cause trouble for BitTorrent clients or other P2P clients and the reason why. If you are using one of the following ISPs, please consider finding a new, better one. If your ISP is not on the list and you have reason to believe they are shaping traffic, come to the IRC channel and tell the OPs so that they can add it to the list. However, before you do that, please ensure that you have read about good settings and NAT problems.

One of the biggest problems are providers that that perform traffic shaping on P2P protocols, see Avoid traffic shaping for advice on how to counter that. You’ll need that if your ISP is listed with an encryption level greater than 0 or a question mark.

TM-Net Fair Usage Policy

Filed under: Internet, Service — expertester @ 2:57 am
Tags:

TM is committed to ensuring our customers receive the best broadband service at the most competitive price. To achieve this goal, we provide a contended broadband service. This means our Internet bandwidth (capacity) is catered to be shared by all our customers at any one point in time, to ensure we provide a satisfactory and acceptable performance on an equal basis to all our customers.However, a small number of customers use more than their “fair share” of the Internet bandwidth provided by us. On average, about 10% of our customers are using a disproportionate amount of Internet bandwidth. These customers degrade the performance of our broadband service by taking bandwidth away from other customers, who use the service fairly.

“We do not take away bandwidth….”

For example, some customers use P2P or file sharing software, which constantly sends and receives videos and other types of very large files, throughout the day. These activities (download and upload continuously) use a lot of bandwidth and can significantly reduce the connection speed, which other customers are getting to access the Internet during peak hours. We don’t believe this is fair to the vast majority of our customers.

We wish to bring to your attention our traffic prioritization policy with regards to P2P and Fair Usage Policy. We would like to reiterate that the P2Pthroughput is subject to peers (seed) availability and their throughput as well. Kindly note that TM does not have any control over peers’ availability or throughput.

The Fair Usage Policy automatically identifies the extremely heavy users and manages their bandwidth in order to protect the service of all our other customers.

This traffic prioritization policy will protect the quality of service for the majority of our customers when they use the service, while at the same time,still allowing the extremely heavy users to continue to send and receive files with certain restrictions. With this policy in place, we will prioritize Internet activities like web browsing, live streaming, messaging applications and VOIP access while traffic to P2P sites will be given lower priority,due to the high bandwidth consumption of such services.

We wish to also highlight that as an Internet Service Provider (ISP), TM only provides access to the Internet and does not guarantee content delivery and performance where it is not within the domain of TM as an ISP. In fact, our international traffic management policy is designed to cater for all our customersso they have an optimal surfing experience within the normal limits of Internet usage.

As our priority is for all our customers to have a positive Internet experience, we wish to emphasize that it is important for all our customers to practiceresponsible usage of the allocated bandwidth based on normal usage.

We would like to reiterate that we are not against the use of P2P but we would like to educate our customers that the usage of excessive P2P does impact the overall service availability to our other customers.

TM does provide every customer with an allocated bandwidth, where other customers may use when not used by the others. Unfortunately, the nature of P2Pmore often than not, takes more than their allocated bandwidth, thus causing undue setbacks for other users when they want to use the service.

As a responsible service provider, we believe it is our responsibility and commitment to educate and encourage responsible usage of the infrastructure weprovide.

Latest Izzi Speedcheck

To be fair to my previous review, I re-evaluate Izzi performance base on current environment.

To be honest, after a good review a couple of months ago, Izzi performance drop significantly. It started in somewhere in the midle of November where I only enjoy half of the advertise speed. Roughly 50-60 KBps. It even drop to 30 kBps when peak hour. I call Izzi Customer Service 3 times. The first and second, the customer service just told me that he will check and re-inform me later…but no such luck…he just keep quite. I send them 3 emails, and they only reply the last one. My 3rd call, I speak and complain a bit harsh ( no more gentlemen manner). To be surprise they lodge me a report and give me my report number.

The last customer service guy did call me 2 times and ask me to provide him a screen shot (izzi speed test result + signal strength. I did provide and it clearly state even I received 100% signal, my speed still limited to 500 kbps. This is really piss me off because I pay for 1 Mbps not half of it. And guess what, that guy told me that, each iBurst tower will support up to 50 user simultaneously. And according to iBurst white paper, each iBurst tower only able to provide 24 Mbps downstream. So, if all 50 users doing heavy download (torrent or FTP), there is no way I can enjoy 1 Mbps download speed. Dang. Izzi actually greedier than TM-Net.

Here is my latest screenshot for Izzi speed test result with 100% signal strength. Location : Kelana Jaya. 15th floor.

Mind you that this result is more optimist compare to real world speed. This is my connection (speed test) with Izzi Server as my ISP. So, my speed should be lower when I download oversea content or torrenting.

TCP Optimizer Review

I knew about this method quite sometime. But in indirect way. So to speak, reading description from various of tuning software. But, I never felt any significant different. Maybe it is because I use Streamyx at that moment (wired connection) or simply the tuning software just not efficient.But last night, after reading various recommendation from techies at LYN, I decide to try it on my own. Login to SpeedGuide website, and read those documentations & FAQ, seem the reason between this optimization really make sense.

Basically, for every packet of data we receive and transfer, we want it to be as large as possible. However, fragmented data will hampered the transmission performance. So the idea is, to find the biggest packet possible without being fragmented.

So, i use that software (dont even need to be installed), and let it do its trick. Viola, I gain almost 200 kbps extra when I do heavy download. Reaching a bit higher 1000 kbps now is not a mission imposible now. Compare to 800 to 900 kbps previously, I think it really worth every single minute I spend to explore about this optimization tools and method.

Izzi Broadband

Review Date : 25 October 2007

Izzi BroadBand (iBurst) Izzi broadband (www.izzi.com.my) might a new player in Malaysia market but what they can offer definitely could eat any big boys out there.

Izzi package (PCMCIA, USB and Ethernet)

* Mobility (even traveling 100 km/h in car)
* Speed (1 Mbps, almost consistant, not offering 3.5 Mbps but 95% of the time getting 350 kbps…. Telco M for example)
* Price (RM 98 definitely cheaper than Streamyx + Phone Rental cost)
* Radius of Coverage (effectively 13 km, compare to 5 km for ADSL or streamyx).

I spend almost a week scouting every single information about this service. Every single page in LYN forum regarding Izzi. No need to mention googling like nerd. But, thats really worth consider so many wireless and wired broadband player in this market has so many dirty tricks under their sleeve.

Imagine you subscribe to Maxis broadband 3.5 Gbps, but have 3 GB max download per month, able to heavy download from 1 AM to 6 AM only and most of the time you just enjoy 10% of the advertised speed. This is really a nightmare. I really thanks to God for making my maxis broadband registration pain in the arse which I cancel it before I bonded to their contract. Lucky me.

And what about streamyx? I used to use this service for years (start from TM reduce the broadband package to RM88 (at that moment RM88 for 512 kbps )). And for years, I can’t count how many times I call their customer service, or pay a hostile visit to TM Clickers. No matter what I do, I still need to wait my problem to be fixed in 3 to 2 weeks. Yup, the longest one was 2 weeks. And I felt like a cripple man when I have no broadband at my disposal.

No need to mention about disconnecting problems, bittorent throttled down speed, high latency to US server (especially for online gaming), bandwith quota and had no connection when raining day. WTH man, we are in Malaysia, not Africa. The rain season could last couple of months. And for couple of months, I just say… ” Oh please god…please”. Luckily I never call any “Bomoh Hujan” yet.

So, Streamyx is not an option for me any logger. And any 3G broadband I consider as crap. Too many ports closed, so many limitation, slow speed and high latency connection. WiMax? So expensive. I will not spend more than RM100 for my broadband. That’s my ceiling. So, Izzi is the best bet I have. And well, the outcome ….. a very happy and satisfied customer.

And this is my point of view for izzi. The picture you may see here is my download speed in kiloByte. I am happy with that speed considering this is wireless technology, close to their promise really stable.

The latency to izzi server averagely 80 ms and to google.com averagely 350 ms. Pinging to microsoft.com avergely 400 ms.

Using uTorrent with default setting, I torrent couple of files last night, and I manage to get 90 kBps. But, due to the nature of torrent, sometime it fluctuate quite heavy. I could say 70 kBps is realistic average speed for my good seed torrent downloading. The best thing I love about izzi is, i can play my mmorpg online game even I was torrenting at that moment. That was close to impossible when i use Streamyx and ZTE modem. During the torture period, I am torrenting 8 movies, downloading 600+ MB roseonline client game (using download manager), and play rose private server. Everything run smooth without any significant lag in the games. Browsing speed also not affected much.

Overall, I have better consumer experience using izzi compare to streamyx and maxis broadband. RM 1258.00 for izzi iBurst USB modem + 12 months subscription really worth every single cent. I will pay more than RM 1400 if I go for streamyx. And streamyx will bond me for the whole 24 months if I am not mistaken.

The payment scheme for easy is more likely a prepaid version of broadband. For the first year subscription, you need to pay upfront RM1258 for USB iBurst modem. For a complete list for the product package, price and modem… click here . Afraid not, they offer interest free payment scheme for 12 months using major credit card. So, basically you will only need to pay more or less like any broadband subscription.

And after 12 months, they will not bug you anymore. If you want to use their service, you may buy the credits base on your need. 1 month, 5 months or any number of months. It’s really up to you. And base on my under understanding, they will discount for those who buy credit for the whole 12 months lump sum. Each month will cost you RM98 only. No hidden charge, no tax what so ever. It just like a prepaid. You pay RM98, you get 31 days izzi broadband. And the good parts is, the modem which worth more than RM600 (I doubt so..LoL) will belong to the user provided we subscribe the service for the whole year. For me this is more than worth. Paying RM 99 for streamyx 1 Mbps package (which RM 11 for 24 months for the modem) is really rip off. The modem could be bought as low as RM 70.00. Even ADSL modem + router + wireless + switch will cost around RM 150 only. RM 11 * 24 = RM 264. Ouch. You can use this izzi modem in any iBurst coverage (internationaly I mean).

There is a satisfaction guarantee policy. Most of the salesman will tell you, within 7 days, if you do not satisfy with izzi, they will refund 100%. DON’T believe this. This is utterly marketing gimmick by not so etiquette salesman. The truths is, the 100% refund policy is only subjected to everything BUT registration and admission fees (RM 180). So, bear in mind. And dont be a newb. Once you do your online registration, your RM 180.00 already fly to the salesman pocket and izzi. They say no question ask but I notice that there are 2 terms need to be met before you can claim your refund. No coverage AND download less than 3 MB. So be my guest.

75% refund before 3 month of usage, and 50% refund before 6 months of usage (in case their service down at your area).

So, I took ingenious step. During their roadshow at DigitMall, I ask is there any chance izzi salesperson to come to my home and demo to me about the connection speed, either using his notebook or my PC. (I am quite sceptical about wireless broadband, too many contributor to make the performance drop below acceptable level). And they give me their friend card and ask my mobile number. Not even 2 hour after I visit the road show, the sales person call me and ask me when can he demonstrate to me. I remind him that I will test the connection and if ONLY I satisfied with the product, I will buy it. The salesperson took this concept in very open and professional way.

So this guy come to my home (level 15 at Kelana Jaya). Setup the izzi USB modem (demo unit) to my PC (my PC located in a room with no windows). Login his account and let me try as much as I want. He just did his stuff and dont even care what I was doing. Things I do while testing :

* Dowload from nzones using download accelerator (12 segments)
* Torrenting the highest seeder torrent
* Browsing
* Test latency (ping) to several website (jaring.my, tm.net.my, google.com, microsoft.com and nzone.com)
* Speedtest.net and streamyx speed test
* Monitor the signal strenght (100% most of the time. But it can fluctuate a bit to 80% withotu antenna and I close the door)


So, after do all this things (not all at once), I really satisfy with the performance and pay him.

So, end of the day, I get a broadband which more stable than streamyx, as fast as streamyx (when streamyx in ‘good’ mode of course) and wireless. No need to mention I pay less too :)

Don’t take my word. As the sales person to perform short demonstration at your location and you decide.
Free download manager download at 75.5 kBps and Torrent at 20.2 kBps at once.
