Fixing Internet Problems
If your classroom network is not working, follow these steps to fix common issues. If you still have trouble, check the Wi-Fi Setup Guide to ensure everything is connected correctly.
Quick Check List
1. Restart Devices
Power off your routers and the server (main) computer, then turn them back on.
2. Check Physical Connections
- Ensure the grey or white network cables are plugged in firmly at both ends.
- Confirm the Server machine has a solid cable connection to the main router.
- Look at the router lights to ensure they are on and blinking.
3. Ensure a Single Server
Verify that only one computer on the network is set as the server in tl-sys-configure. Having two servers will cause the network to fail.
4. Check Student Configuration
On a student computer that cannot connect, run tl-sys-configure and confirm:
- Role: Set to
client. - Wi-Fi Name: Set to the correct network name.
5. Check Server Status
On the Server computer, check if the “address server” (DHCP) is running. Open the terminal and type:
rsv status dhcpd4Expected Result: The status should show
run. If it showsdown, typesudo rsv restart dhcpd4.
Common Problems & Solutions
| Problem | Quick Fix |
|---|---|
| No Wi-Fi visible | Check if the Server and Router are powered on and the Server’s own Wi-Fi is disabled. |
| “Limited Connection” | This usually means the address server is not working. See Step 5 above. |
| Very Slow Network | Too many computers on Wi-Fi. Connect more machines using grey/white cables. |
