Agreed entirely. You should not ha e to pay for a replacement AC adapter.

But I guess either you:

  1. Return the entire package and get a package that works but have down time but you’ll be without for the unit for a while.
  2. Try and trouble shoot and find the problem. If it’s the AC adapter you could reach out to gl. Inet and get them to send you a new adapter and still be to use in the meantime with your temporary working adapter.

No ones ever suggested they should wear any cost, just basic troubleshooting.
