Configuring HUAWEI E1750 for OpenDNS

I have recently been using a T-Mobile Mobile Broadband USB stick 610 to connect to the Internet, but pages keep failing to update. (Even Google kept timing out on me).

The status bar of Firefox said something like “looking up google.com”, so the problem was either a connectivity issue or a DNS issue. DNS converts something you and I understand (Google.com) into something the computer understand (a number). I tried opening Google directly at 173.194.37.104 (Google UK) and up popped the Google home page. This is apparently a common problem with mobile Internet. The answer is to use somebody else’s DNS Servers. A common choice is to use OpenDNS; there is no need to sign up, simply specify their servers at 208.67.220.220 and 208.67.222.222

T-Mobile’s technical support were no help when asked how to reconfigure the device to use OpenDNS instead and every time I tried to edit the configuration under Control Panel\Network and Internet\Network Connections, they kept getting overwritten.

The answer is to configure the DNS server through the Internet Manager which starts each time the stick is plugged in.

  • Start T-Mobile Internet Manager
  • Click on Tools then Options…
  • Select “Profile Management” in the left hand pane
  • Click on New button
  • Give profile a name (eg T-Mobile UK OpenDNS)
  • Set APN to static general.t-mobile.uk
  • Set Authentication as follows
    • Access number *99#
    • User name t-mobile
    • Password tm
  • Click on the Advanced… button
  • Click on Primary DNS and enter 208.67.220.220
    DNS Settings will change from Dynamic to Static
  • Click on Secondary DNS and enter 208.67.222.222
  • Click OK button
  • Click Save button
  • Click Set As Default button
  • Disconnect and Reconnect to T-Mobile

That’s it.

If you want to use the advanced features of OpenDNS, you will need to sign up for an account and use the OpenDNS Updater to keep OpenDNS informed of your Dynamic IP Address.
