Automatic Dial-up Internet Connection and Task Scheduler

WARNING

Annoying Network Shenanigans

My desktop connects to the campus network via Ethernet but requires dial-up to get online. Hilariously, Tencent’s ancient, never-updated TIM client throws an error popup if it tries to log in without an internet connection.

Every time I boot up, I have to manually enable dial-up in the settings. TIM’s auto-start feature kicks in first, triggering the error and making the auto-start function look comically useless.

So, I wrote a batch script to auto-connect and set it to run at startup via Task Manager. But it launches at the same priority as TIM, often failing to establish the connection before TIM auto-logins and throws the error.

The workaround? Using Task Scheduler to delay TIM’s launch by 15 seconds after the auto-connect script runs.

(For convenience, I placed the batch file in the Startup folder. The hidden, highest-priority Task Scheduler job kept failing because brilliant Huorong security blocked undetectable scheduled tasks. After several debugging attempts where the script only ran after login, I almost thought my settings were wrong.)

Now, my ¥68 fingerprint reader feels utterly pointless.
Wondering if any tech-savvy folks in my contacts have a better solution.

I do have a wireless card, but it’s unreliable. The campus network often requires web authentication. My VPN auto-start clashes with this—I have to:

1. Disable VPN → 2. Complete web auth → 3. Re-enable VPN → 4. Close TIM’s error → 5. Restart TIM.
   Infuriating doesn’t even begin to cover it.

Dial-Up Script

Create a text file (.txt), paste the following, save it, then rename with a desired title (e.g., reconnect_internet, preferably in English) and change the extension to .bat.

rasdial "Your_Connection_Name" "Username" "Password"

Auto-Dial on Boot & Reconnect

1. Right-click Windows icon (Start) → Computer Management → Task Scheduler → Task Scheduler Library.
2. Create Task → Set name (e.g., “Reconnect”) →
   • Run whether user is logged on or not →
   • Run with highest privileges (optional) →
   • DO NOT HIDE! →
   • Configure for your OS (e.g., Windows 11 users select Windows 10).
3. Triggers → New →
   • At startup (for auto-connect).
   • New → On event →
     • Log: Application (scroll to second-last) →
     • Source: RasClient → OK (for auto-reconnect).
4. Actions → New → Start program → Browse to select your .bat → OK.

Confirm (requires entering your Microsoft account password, not PIN. If errors persist, check the “General” tab for correct user account matching.)
