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