Network Infrastructure in My Home – After 10 Years

I wrote an article about 10 years ago (on September 13, 2002) named:

Network Infrastructure in my Home in Shanghai

Time flies. So many things changed since I wrote that blog ten years ago.

  • I was at age of 25 at that time, and now I am 35
  • At that time, I was an engineer at Microsoft who likes and good at writing technical articles like Knowledge Base Articles. Now, I am an entrepreneur who only cares about the network to be working than anything else.
  • At that time, Dial-up was still an option (Just dial 8163 for Internet?) and now it is not.
  • At that time, The Great Wall Broad Network was still an option, and now it consolidates to just China Telecom, and few similar.
  • At that time, broadband just started. The first paragraph of my old article reads: “For friends in Shanghai, they are curious about the broadband, which is new to the city.”
  • At that time, I only have one client device – a desktop PC – connecting to the Internet. Now, I have a dozen. (While, that PC is famous because it is in my reading room, and accessible from the Internet via http://home.wangjianshuo.com, the domain I later migrated to hosting companies).

So, let me take time to examine the current network infrastructure of my current home – Wendy complained for Internet access many times, and I finally get it to a level that is stable enough to Wendy’s satisfaction.

Broadband Provider - Fiber To The Home (FTTH)

In the recent upgrade, the China Telecom Shanghai changed ADSL in my home to the current FTTB. There is a optical fiber cable at the door of my home, connected with a fiber modem. I pay 150 RMB per month for the 10M speed.

Here is the IP information from APNIC

It seems the IP address is a stable number since it is always connected there. (I started to miss the time when we were using 202.120.xxx.xxx IP address in universities.)

The Shanghai Bell equipment of RG201O-CA is a very simple modem plus a gateway to the outside world of my entire home.

Three Routers

To cover the entire home, I needed three routers. Due to being stupid and too optimistic about the performance of WIFI, I only have limited ethernet cable on the two floors of the home. So I setup it this way:

Router 1: 192.168.2.1 TP-Link WR320R to provides wireless to the first floor.

Router 2: 192.168.1.103 Apple Time Capsule 2T to provide wireless for the reading room

Router 3: 192.168.1.253 TP-Link WR700R to act as a repeater to extend the wireless network of Apple Time Capsule to provide additional coverage for other areas of the house.

WIFI/Ethernet Clients

Obviously, we have much more clients than before to connects to all these wireless and wired networks. Here is an incomplete list:

  • iPhone of Wendy(0C-74-C2-A5-C0-A5)
  • iPhone (18-E7-F4-F6-4A-45)
  • iPad 2 (40-30-04-9A-C3-80)
  • iPad 1 (D8-A2-5E-3D-96-29)
  • iMac (e4-ce-8f-5f-6d-89)
  • MacBook Air (04-0C-CE-D4-0F-52)
  • Sonos Hi-Fi System (00-0E-58-72-39-AE)
  • TCL TV

Obviously, there are much more clients than before, and the count is going up every month.

It is a much more fancy network than many years ago with NAS (Network Area Storage) and other equipments connected to it.

China Telecom is ADSL Spammer

Look at this screen:

screen-china.telecom.spam.png

This is the screen users using Shanghai China Telecom ADSL see when they dial up and first visit a website. The ad is so dominate and changes the way the original page is displayed. It appear for few seconds and then disappear.

In the wild west Internet, what ever behavior is possible, and allowed.

Hotmail Opens POP3

Yesterday, I tried to use Gmail to receive emails in Hotmail, and found out that Hotmail already opens POP3 access to all users. At least for me, I am in China.

Here is the necessary settings:

POP3 Server: pop3.live.com (port 995)

Need POP SSL? Yes

User name: your Windows Live ID, like somebody@hotmail.com (Please note: you have to include the @hotmail.com part, not just the name)

Password: your password

SMTP Server: smtp.live.com (port 25 or 587)

Requires authentication? Yes

Requires TLS/SSL? Yes

That is. You can start to abandon Hotmail.com slow and ugly interface.

16300 Dialup Internet Access

The other day Jack Gu reminded me that the easiest way for anyone to access Internet is still using dial up.

In today’s broadband Internet age, many people may already forget the existence of dial up network. It does exist, and is surely one of the easiest, and most widely available Internet access method. It is especially good for international travelers. Here is how you use it.

Number and Price

The most important piece of information is dial up number, user name and password:

Dial up number: 16300

User name: 16300

Password: 16300

Using this simple number, you can access Internet – yes, the whole Internet (I emphasize it is the whole Internet, because there is other ways to access only Internet in China, which is cheaper).

Cost: 3 RMB/hour

The cost will go directly with telephone bill.

Besides the 3 RMB/hour Internet fee. you still need to pay 0.02 RMB per minute for telephone bill (that is 1.2 RMB/hour).

Look at China Telecom website for more information (Chinese)

At national holidays, Saturdays, Sundays, and 23:00 PM to 8:00 AM next day, it will be 50% off original price.

Why Dial Up

Jack mentioned to me that he has already unsubscribed from brand band and switched to dial up at home – to make things more inconvenient greatly reduce the time you spend on it. That is a good point. I am also considering the same to reduce my time used on Internet at home.

Mac Cannot Access Internet in China

RC has a problem related to Mac. He just got a new Mac and bring it to China. He could not connect the Mac to Internet no matter using LAN, Wireless… It is weird that he can use Skype, but cannot browse any websites.

Livid has a quick response: try to set the DNS to

208.67.222.222

or

208.67.220.220

(This is the OpenDNS)

RC tried, and it works!

Well. It sounds like a miracle.

So if you encounter the same problem, you may try this solution, since it seems not a solution that you can find out yourself.

Why this happens? I don’t know exactly why. I just know the DNS setting of China Telecom is completely massed up.

Network Speed of my FTTB+LAN

Look at the PING result from the HP Pavilion desktop computer in my reading room, to the web server of this blog.

Slow Internet Connection at Home

The internet connection at my home (China Telecom FTTB+LAN) is unbearably slow. In the recent month, I found it was so hard even to load the homepage of this blog.

I doubt whether it was due to the high usage of BT on the community network. The short-come for FTTB+LAN is, the network speed is not guaranteed. When there is less traffic, it can be super fast. But when the traffic is crowded, it can be slow.

I miss ADSL again, but it is not available in my home. Sometimes, I will have to switch to China Unicom CDMA solution. It is even faster than the broadband at home. It is ridiculous.

Movable Type via CDMA

Nice talk with Jia and Victor at night. It is late already. I’m now on a Dazhong taxi back home, passing by the Nanpu Bridge. The whole lighting system for the city was turned off already, so it is a little bit dark now.

I brought my laptop and connected to the Internet via China Unicom CDMA. (To get it, you have to purchase the card and subscribe their service.)

I don’t want to open computer and write an entry today. The car is moving and I am typing. So I call this entry:

Movable Type via CDMA. Have good night!

DSL in Shanghai

DSL (a.k.a ADSL) in Shanghai is the best quality broadband solution I have seen so far.

Iti s better than FTTB+LAN solution (which I am using at home) in terms of quality. ADSL is more reliable and more available. Sometimes FTTB+LAN fails because of lack of maintainance for the network equipment in your area, and it is only available for specific residential areas.

In contrast, ADSL seems always fast and reliable, and most places can just upgrade from a telephone line. I am of very pure luck that ADSL is not available in my area, which is very rarely heard among my friends.

“How Do I Get ADSL?”

It is easy. Just dial 10000 from any telephone and ask for it. They may not speak good English (I heard, since I didn’t try their service yet). If you rent the apartment, be sure to call your land lord to install it for you since it requires some documents.

P.S. This is among the most asked question. Many people cannot survive without broadband, but broadband is not a standard facility for rented apartments. For more information, check the Related Entries section of this article.

P.S. So nice to meet Xiaofeng today. Very inspired by her passion and vision. She mentioned the term “Global Leadership”. I like this one, including its pronouniation. :-)

Visited Internet Cafe Again

I visited one Internet cafe about half an year ago and wrote a report (I could not find it on this site. Strange). I visited another one yesterday, as part of my goal to dive into the details of Internet in China. Here are some photos.

© Jian Shuo Wang

Internet bars, just as the Internet users in China, are highly diversed. There are very cheap bars with bad environment, there are also great bars like this. It is like a 5 star hotel facility. :-)

I wrote an article about the mapping of current Internet situation to the Internet history of America. The article was widely quoted, and it is the first article I wrote appearing at the home of furl.com and the most popular link page on del.cio.us today. I didn’t expect that. Some people challenged the idea of visiting Internet Cafe. I know it is now the best way to learn Internet, there are many more places to visit, like those schools, and the under-developed areas, Internet cafe is a good starting point.

I will continue to visit more Internet cafe. The observation is pretty consistent from the previous visit – 95% or more are on either game or watching DVD, but I am more interested in TALKing with the people there, instead of just watching. To check out the software installed on the computer, to see the history of page visited are also very educational for me. To avoid people claiming it is another commercial show again (some claimed that I claimed to dive into Internet bar as a commerical show), let me record some photos in the English version and prepare to write something more solid later…

P.S. shift of focus?

As I started to work for Kijiji, the scope of my view changed a lot. My focus changed dramatically from the city to the industry. Meanwhile, I become more public than before. The publicity sometimes does not allow me to write as personal as before, but as what I have decided at the very begining of this blog, PERSONAL is much more important than focus. It is as hard to keep writing personal at high publicity as to keep writing as low publicity. Let me try. :-)

Broadband Internet Providers in Shanghai

ADSL from China Telecom

Installation Fee: 310 RMB – including an account and an ADSL modem. NIC (Network Interface Card) is NOT included.

Package 1: 130 RMB/month for unlimited time at speed of 512K.

Package 2: 150 RMB/month for unlimited time at speed of 2M.

Package 3: 200 RMB/month for unlimited time at speed of 4M. (need to check)

Package 4: 1300 RMB/year for unlimited time at speed of 512K. Installation Fee is included.

Package 5: 1500 RMB/year for unlimited time at speed of 2M.

Apply and Information : Phone: 10000 (China Telecom service hotline)

Installation Requirements The area you are living in must meet the installation requirements and ADSL ports should be available. Check with their call center by your address. For example, I used ADSL in my old house in Vanke Waltz Garden but cannot install it in Pudong. Poor me. If you live in downtown Shanghai, chances are your place is ADSL ready.

My Personal Experience

I miss ADSL badly after I move to Pudong. ADSL is best broadband solution I have ever experienced. The speed is good enough for Internet suffering and downloading. It assigns a dynamic but real public IP to client computer, which means, I can setup my own server at home and others can access my site from anywhere. (If you are interested, you may need some dynamic domain service provider like ORAY.NET to bind your dynamic IP address to a domain name) ADSL from China Telecom is very reliable. I didn’t experience drop line or other unpleasant events in my one year subscription with ADSL. The 10000 call center’s service is pretty good – it is the standard service from the largest telecom infrastructure provider in Shanghai. I never called them because I didn’t meet any trouble.

Great Wall Broadband

Installation Requirements: Great Wall Broadband does not need YOU to take the trouble to install it. They make deals with the real estate company and build the network cable inside the wall of newly built apartment. Check with your property management company to see if Great Wall Broadband is available in your property. If it is installed, then all you need to do is to call them to enable your account and plug a network cable into the network port on your wall. If it is not installed, chances are, you have to choose other options. It is almost impossible for individuals to apply to install Great Wall Broadband.

Installation Fee: 0 RMB if it is installed when you move in.

Fee:

My Comments:

I was a happy customer at very beginning since the speed is really good. But I finally became a very dissatisfied customer of Great Wall Broadband and after complaining with their service team for a month or two, I quitted my subscription and switched to ADSL. Their technology is bad and it pops up the annoying IE time counter that you cannot close. It is stupid to count time for a all-you-can-eat subscriber like me. The company was started by a good professor from Shanghai Jiao Tong University. I have ever worked in his lab for one summer and that summer provided me enough time to start with Internet. I am grateful for the professor but finally said no to his company (and give negative comment). Sorry.

Cable Modem

Cable modem is a service I never tried. I hope I can put some content here from my friends who used cable modem.

ADSL is also Unavailable in my Home

I couldn’t imagine that I would face the challenge of getting Internet access after I move into my new home (Dahua Jin Xiu Hua Cheng) in Pudong. I was disappointed that I cannot use cable modem here. I called China Telecom to install ADSL. Today, I got confirmation from China Telecom that I cannot install ADSL in my home either. The equipment here is not ready for installation. In their technical term, the ADSL port is not available for this area.

Well. There is a long way to go to get Internet access and setup the Network Infrustructure as my previous apartment.

During my free chat with Andy, I learnt that China Unicom offers some kind of CDMA Internet access card – basically a SIM card – that enables a laptop to access Internet like GC75 + GPRS, but faster and cheaper. There is a package of 700 RMB for unlimited Internet access at speed of 200+ kps. (The data is not confirmed yet). The equipment (the PC card) needs to purchase separately.

People are asking me about which is the best broadband solution in Shanghai. Based on my limited experience with some providers, I still recommend ADSL from China Telecom. See my brief review of Broadband Internet Providers in Shanghai.

Cable Modem Unavaible in Pudong

I thought Pudong is a completely new area. I was wrong. Tonight, I borrowed a cable modem from Xiao Gao, hoping to install it in my home. Since the cable modem authentication is bound to MAC address, it should be connect-and-play without entering user name or password.

I connected the black magic box of cable modem to the cable port but the cable light didn’t turn on. I called 96877 for help. They checked the address of my apartment and told me: “Sorry. The cable TV system is not upgraded to support duplex data transfer right now. So it is impossible to install cable modem in your apartment”.

I asked whether there is a plan for the upgrade, the answer is “I don’t know”.

This reminded me that Pudong is not built from ground up. The areas are upgraded from counties and villages where the basic infrastructure is still not as good as Puxi. Puxi has been a CITY for two hundred years while Pudong is not. I cannot expect a brand new area there. Pudong new district, the government, is new, while Pudong is old, very old.

P.S. I helped Patrick, the first user of my Apartment Offered Form to put his apartment on this site. To avoid putting such advertisement (although it is free public service) to the headline of this blog, I marked all such posts’ date to be May 22, 2004.

Use GPRS in Shanghai

I received query about GPRS today from Boris in Germany:

I like your weblog, lots of interesting information in it :-) Thanks for that!

I have read your messages about mobile phones in china. Now I am interested if you have any more details on GPRS. I have heard that there are different flat rates in China for about 200yuan / month with umlimited traffic and roaming within china. I really can’t believe that but maybe you can comment on that.

200 RMB / Month for unlimited traffic

The good news is, at the time this article is written, it is true. Here is what the Shanghai Mobile announced on their Chinese website.

Monthly fee: 0 RMB, then 0.03 RMB/KB

Monthly fee: 20 RMB for 1MB, 0.01RMB/KB

Monthly fee: 100 RMB for 20MB, 0.01RMB/KB

Monthly fee: 200 RMB for unlimited GPRS access

There is no roaming fee if you use GPRS in other cities.

Network Infrustucture in my Home in Shanghai

11:50 PM

I have been asked about how I can access Internet. For friends in Shanghai, they are curious about the broadband, which is new to the city.

Dial-up: Basically, residents in Shanghai have lots of choices for Internet access from home.

  • The China Telecom is the largest and most popular provider of dial-up access.

    Telephone #: 8163

    username: 8163

    password: 8163

    The Internet service fee will be charged to the caller’s telephone bill. This is very convenience. We don’t need to apply a user account. (What about other regions in the world? Writhe comments and let us hear you.)

  • Their there many other ISPs are providing Internet Access card. Users buy the cards and can dial the number on the card for predefined period of Internet Access time. It is also good and cheaper than 8163 service.

Broadband

There are many service providers are competing to gain more market share here in Shanghai

  • China Telecom is selling ADSL – the method to use normal telephone line to transmit digital signals, though greatly speed-up the data transition.
  • Cable TV providers are persuading users to use cable modem to access Internet.
  • China Unicom, which don’t have the fixed line telephone are using wireless technology to gain its market. User with wireless LAN adaptor can subscribe to their services.
  • Other broadband providers like Great Wall Broadband – the provider I chose. They are using traditional LAN technologies for users in a residential area.

Let me share some facts of the broadband I am using.

Speed The inbound network cable provides 100M access to other servers on the LAN, and provide pretty good Internet access rate (not very sure about the exact bandwidth now) I tried to download some files, the transfer rate displayed on downloading dialog box is typically 40 KB/sec to 100 KB/sec.

IP address GWBN is providing dynamic, real IP address.

  • Dynamic IP GWBN uses DHCP to allocate IP addresses on a LAN. Heroically, the IP may change. However, because currently the number of subscribers is far less than number of IPs in the IP pool, the IP addresses for my computers never changed. So I can safely direct my domain http://home.wangjianshuo.com to my IP address 211.161.107.18.
  • Real IP Unlike China Telecom broadband and other broadband who are using NAT (Network Address Translation), GWBN provides real IP address. I queried my IP address 211.161.107.18 in www.apnic.net, the result looks like this

    inetnum: 211.161.107.0 – 211.161.107.255

    netname: GWBN-SH-COMMUNITY145

I guess the so-called “# 145 RESIDENTIAL COMMUNITY” refers to Vanke Waltz Garden. That means 773 families are sharing the 255 IP addresses. It is pretty good, since only about 5% of the residents are subscribers now.

I randomly checked some IP from 211.161.0.18 to 211.161.253.18 and found them all belong to GWBN. It seems the company has lots of IP addresses for the broadband services.
