<07-10-2016> Notes on establishing mobile broadband connection with EMOBILE GL01P (Huawei) in Debian(jessie+GNOME)

DISCLAIMER: I don't take responsibilities for any damages caused by performing what I mention below.
Before trying to fix your problems, it is better to back up your important data and carefully check present configuration of your devices.

• The values required in configulation on GNOME's control panel are found by following steps:

  1. Access to EMOBILE GL01P Setting Tool page (default: http://192.168.1.1/)
  2. Type "admin" as User Name and enter Password to login
  3. Settings(at the left side) > WAN Settings > Profile Settings

  Therefore the page shows the value of Dial-up Number, User Name, Password, Authentication (PAP in my case) and APN.

• It may be better to restrict Inner authentication to the method GL01P showed on the above page (i.e. in my case I restricted it to PAP).
• GL01P's wlan needs to be disabled before connecting via mobile broadband.
• When it doesn't work, reboot PC and GL01P. Note that GL01P is connected on PC's booting.
• Unlike during connection in Windows, GL01P's display doesn't change to “USB Modem” screen. However, there's no problem with connection itself.

<06-26-2016> Choppy sound during network activities on ThinkPad E430 (Conexant 20671) w/ Win10

DISCLAIMER: I don't take responsibilities for any damages caused by performing what I mention below.
Before trying to fix your problems, it is better to back up your important data and carefully check present configuration of your devices.

This is what I've experienced after upgrading Win7 to Win10. Although I uninstalled and reinstalled the device driver of the sound card several times, it wasn't resolved.

In my case, I realized that choppy sound occurred only when there were network activities on my PC.

For example, sound rarely came choppy when I simply opened foobar2000 right after startup, while a music played on foobar2000 began to be choppy frequently (every a few seconds) after I opened Google Chrome.

Thus I suspected that this problem had a relation to some problem with the network devices.

As a result, it was true.

What I did is below:

1. Press [Win] + X and open Device Manager.
2. Open the tree of Network adapters.
3. There is a list of devices in Network adapters tree. Double-click one of them to open the property dialog.
4. Open the Driver tab and click “Update Driver”.
5. Unless the device needs some special configuration, select “Search automatically for updated software”.
6. When there's something to update, Windows automatically starts to download and install it. Wait until the update completes.
7. If Device Manager demands to reboot, reboot PC.
8. Perform 3 to 7 on every device listed in Network adapters tree if chopping still occurs.

When I checked Device Manager, the device named “Realtek PCIe GBE Family Controller” used an obsolete driver (though I didn't check its version, I saw its date was in 2012!).

After I updated that driver, I never face choppy sound, even with browsing the Internet or performing Windows Update.
