3.    What wireless LAN cards are compatible?

Generally speaking, IEEE 802.11g / IEEE 802.11b / IEEE 802.11n Wi-Fi certified wireless LAN cards are compatible with our wireless service.

4.    I do not have any wireless LAN card, is there any rental service?

We do not provide such rental service.

 

5.    How can I know the quality of wireless connectivity between my wireless LAN card and the Access Point?

Your wireless LAN card should come with some utility programs that allow you to monitor link quality and signal strength. Please refer to the user manual of your wireless LAN card for details.

6.    What will be the coverage of the wireless signal within the hotspot?

The wireless signal of the Access Point usually can cover users within 50m range in a closed environment. The data rate will drop as the user is further away from the access point and wireless signal strength becomes weaker.

7.    What factors will affect the signal strength?

Signal strength will be affected if the wireless LAN card or Access Point is placed near metal surfaces and solid high-density materials. If there are obstacles in the radio signal path between the Access Point and wireless LAN card, radio signal may either be absorbed or reflected. The coverage will hence be decreased. In addition, other products that operate in the 2.4GHz radio spectrum, including microwave ovens and some cordless phones, may cause interference. As a result, please keep away from microwave ovens when you are using our service.

8.    What is the bandwidth / throughput of this service?

The downstream bandwidth is up to 6Mbps while the upstream bandwidth is up to 640kbps provided that the wireless signal between the wireless LAN card and Access Point is good. Data rate will drop if the signal strength is weak and is subject to extraneous factors. Different Access Point may have different bandwidth.

9.    The web browser does not bring me to the login page. What should I do?

Starting from 2 Feb 2015, CMHK Wi-Fi service will gradually change SSID/ESSID from “CMCC” to “CMCC-WEB”. If both SSID/ESSID “CMCC” and “CMCC-WEB” are available, please try to connect SSID/ESSID “CMCC-WEB” first.

First of all, please check the SSID setting on your wireless LAN card. Make sure the SSID is set to "CMCC / CMCC-WEB" (all capital letters). Some wireless LAN card requires you to reboot your computer after network name change. Next, check the quality of the wireless connectivity between your wireless LAN card and the Access Point. If the link quality and signal strength is low, you may need to change the position in order to improve the link quality. Some wireless LAN card allows you to install an external antenna. It can improve the link quality to some extent after installing an external antenna.
If the problem persists, please make sure your computer meets our minimum system requirement of wireless Broadband service.

Please make sure you have disabled the proxy server setting on your Internet Explorer by going to "Tools" menu -> "Internet Options..." -> "Connections" -> "LAN Setting...". Uncheck the checkbox of "Use a proxy server" and then click "OK".

If it still does not work, check if your wireless LAN card is using a fixed IP address. If so, please configure your wireless LAN card, Gateway and DNS to obtain IP addresses from remote server. In some rare cases, the built-in LAN card of your computer or notebook may interfere with your wireless LAN card. You may need to temporarily disable the built-in LAN card before you can use our service. To disable it, click "Start" -> "Settings" -> "Control Panel" to open the Control Panel. Next, open "System" from the Control Panel. Click the "Device Manager" tab and then double-click the built-in LAN card icon.
Click "Disable in this hardware profile" and then click "OK".

10.    I cannot login successfully. What should I do?

First of all, make sure that you are eligible for and you have not deactivated the use of Wi-Fi service.
Make sure you have entered the correct login name (your mobile number) and password.

11.    Can I use the same login name for logging into the service with 2 different devices at the same time?

No, multiple login is not allowed. The earlier login will be disconnected by the latter one..

12.    Is there any connection timeout?

Yes. There is an idle timeout of 10 minutes. You will be disconnected when there is no data transfer between your device and the Access Point after 10 minutes.

13.    I have accidentally close the Login status pop-up window. How can I disconnect?

Please go to the web page http://wifi-hk.cmi.chinamobile.com and then click the "Logout" button to disconnect.

14.    While I am using a PDA, how can I disconnect if I forgot to bookmark login status page?

Please go to the web page  http://wifi-hk.cmi.chinamobile.com and then click the "Logout" button to disconnect.  We suggest PDA users to bookmark this page to disconnect easily.

15.    I forget to logout before turning off my notebook or PDA. Am I already disconnected?

Turning off your notebook or PDA does not disconnect your connection, you will be automatically logged out after a 10 minutes idle period. For Pay-Per-Use users, the charge counter will be continued until the user successful logged out, or until system timeout and disconnect automatically.

16.    My notebook is idle and gone into sleep mode automatically. Am I still connecting to the service?

Yes, you are still connecting to our service. After you have waked your device up, you should be able to access the Internet without going through the login procedure. If not, please restart your device and try again. However, if the 10 min timeout session is reached, you need to login again before you can access the Internet. For Pay-Per-Use users, the charge counter will be continued until the user successful logged out, or until system timeout and disconnect automatically.

17.    My notebook or PDA hangs while I am using Wi-Fi service. Should I re-connect after reboot?

No, you are still connecting to our service. After you restart your device, you should be able to access the Internet. For Pay-Per-Use users, the charge counter will be continued until the user successful logged out, or until system timeout and disconnect automatically.

18.    My connection to the Internet was lost. What should I do?

This situation is usually due to poor wireless connectivity between your computer and the Access Point. You may need to change the position in order to improve the link quality. If it still does not work, please restart your device and try again. Please note that you are not required to re-login after reboot.  For Pay-Per-Use users, the charge counter will be continued until the user successful logged out, or until system timeout and disconnect automatically.

19.    I have a fixed IP address assigned to my wireless LAN card for my office LAN use, do I need to change the setting to use Wi-Fi service?

You cannot use Wi-Fi service without changing your system IP setting.
Please refer to the user guide on how to configure your wireless LAN card to obtain IP addresses from remote server. For your own reference, please note that the original information before making any changes.

20.    Are there any security measures when I use Wi-Fi service at public access locations?

To increase the security level, your Login ID and password are encrypted and sent via SSL to the server. The user is also advised to deploy
1.     VPN technologies - to protect the privacy of all sensitive over-the-air data and transactions.
2.     Personal Firewall technologies - to protect the user's station from WLAN based attacks and exploits.
3.     Antivirus technologies - to protect against WLAN based exposure to other infected devices and hand carrying the problem back to the users' private network.
You are also advised not to handle sensitive data in public area.

21.    Can I use Wi-Fi service to receive email?

If you wish to send or receive email via webmail, you will be able to do so no matter if you are using the email account of an ISP or email service provider. If you wish to send or receive email via email software, please fill in the server name (check with your ISP or email service supplier) in the Incoming mail server (POP3) and Outgoing mail server (SMTP) section. If you encounter any difficulties when you send or receive email, please try to receive email first before sending email out.

22.    Will my mobile device switch from Wi-Fi connection to mobile network (data) connection automatically?

Some mobile devices may switch to mobile network (data) connection automatically when they are out of Wi-Fi service’s coverage, so please check your mobile device which connection mode it is in before you attempt any kind of network connection.
