The most challenging aspect of life in China for many foreigners may be the Internet. In addition to many of our favorite sites being blocked by the Great Firewall of China, the Internet here can often be painfully slow. Here are some tips for dealing with both problems.
The Firewall can be overcome with VPN, allowing a direct port to a foreign server to be established with encrypted communication. I use ExpressVPN (https://www.expressvpn.mobi/). It costs money, but it’s worth it and I believe it to be the best service with the best technical support to help you deal with the challenges of connecting. It also adds some extra security since data to and from your computer is encrypted, so it’s good to use for online banking and other sensitive issues. It slows everything down, though.
The general problem of a slow Internet connection in China may be due in part to the heavy work of monitoring Internet usage and to rapidly expanding demand on existing infrastructure. There’s a lot of data requiring a lot of surveillance. But many times foreigners living in China don’t realize that the service they are getting in their apartment can be upgraded to faster service. The base local speed (China to China connections) may range from 10 Mps (10 megabytes/sec) to 100 Mps. If you need higher speed, contact your provider (often China Telecom, reachable by dialing 10000–and yes, they do have English speaking support) and check into an upgrade.
Understand your connection speed by doing speed tests. A good test that might not load for you in China (sometimes it does, sometimes it doesn’t) is SpeedTest.net. This service can use servers in China to test your latency (ping delay), download speed, and upload speed. If your download speed is limited to around 10 Mps, using the Internet is going to be painful. Upgrade. In Shanghai, you can use a China Telecom service at http://sh.189.cn/support/netreport/ to test you download speed with local servers to see what your maximum speed is likely to be. It’s in Chinese, but you don’t need to understand Chinese to use it. Click on the green button that says “开始测速” (begin testing speed). The numerical result is in Mps. You can also use other speed tests that measure data transfer involving US servers. Numbers will be lower than using Asian servers, of course. ATT has a speed test and so does Comcast (Xfinity).
For best speed, make sure you have background processes off (things like software updates, online backup, etc. can slow you down) and don’t have too many browser windows open. For best speed, bypass the slight delay of a wireless router and plug directly into the Ethernet output jack on the back of your cable modem or router — but the gains will often be minor. Also beware of prime times when everybody else is trying to download movies or play games: the Internet can really bog down in China from about 7 PM to 11 PM. And weekends, lunchtime, and so on.
