Hi!
It sounds like your modem is struggling to establish a connection. Here's what you can try:

Reboot your modem:
- Unplug the modem from the power outlet.
- Wait about 30 seconds.
- Plug it back in and wait for the lights to stabilize.
Check the cables:
- Ensure the cable connecting your modem to the wall socket is secure on both ends.
- Check for any visible damage to the cables.
Observe the lights:
- After rebooting, the power light should turn on first.
- Then, the DSL/WAN light should appear.
- Finally, the internet light should turn solid green or blue (depending on the model). If it's still flashing red, the modem is not receiving a proper signal.
Contact support for a line test:
- If the issue persists, you may need to contact your ISP's support team and provide them with your modem's serial number (found on the bottom of the modem).
- They can run a remote line test to see if the problem is on their side.

In cases where a weak signal is detected, a technician visit might be needed. If you want, I can walk you through how to request that as well.
Hope this helps!
