I can't make the wifi work

Hi,

I am living in a student house where we have two types of Wi-Fi: eduroam and hotspot.smarteye.eu. I am trying to create a private sub-network using the GL-SFT1200 / Opal device.

Here’s what I’ve tried so far:

  1. Ethernet Connection (hotspot.smarteye.eu): I connected the Opal device using Ethernet, but it didn't work. There were no error messages, but I didn't have any internet access.
  2. Wi-Fi Repeater Mode: I connected the Opal device to the Wi-Fi network. It didn't prompt for the login portal, so I manually opened it and logged in. However, I still didn't have internet access.
  3. Eduroam: I logged in with my username and password, and it connected, but again, there was no internet access.

Here’s what I’ve tried to troubleshoot:

  • Disabled DNS Rebinding Attack Protection
  • Verified that no VPN services are running
  • Tried MAC address cloning

I hope someone can help me with this issue.

I worked in student accommodation and I know basic theory for WiFi students. It is a captive portal for student WiFi. Inside the portal, you could add Mac address to any device but the router needs contact support for permissions.
For example captive portal:

Most 3rd party router does not support all student accommodations: https://my.glidestudent.co.uk/support/article/personal-networking-equipment

University networks sometime use Extensible Authentication Protocol (EAP), and the GL-SFT1200 does not support it. Check with your IT department, and if you need a router with EAP support, look at this table: Product Comparison - GL.iNet

There is no such settings in our captive portal, I checked the provider website and under the FAQ section they stated using an own router is prohibited. I'll try to contact with the landlords maybe we can find a solution with them to make it work.

Can you confirm are you able to get IP address via Ethernet or wifi repeater?

You said "you logged in with your username and password and it connected", can you explain with some images?

If you get IP address, can you adjust the ttl to 65?

Yes I am getting IP bothvia ethernet and wifi repeater and doesn't show any issues but still no internet access. What is ttl and how can I change it to 65?

I force open the login portal, I enter the credentials and it says logged in (picture from the login portal)

Click “modify” button on the UI and check if you have the ttl settings.

I clicked on but I don't see TTL settings there just the ipv4 and ipv6. I am sorry I am not that experienced with these kind of things ^^"

Can you do more test, as the UI didn't display no-internet?

In you computer, open a cmd window and do

ping 8.8.8.8
ping google.com

ssh to the router and do the above as well.

Then try change the ttl as in this post Change outgoing TTL - #2 by swordfish-ii

Ethernet and WiFi got the same IP at this screenshot.
Without full read of this topic, I recommend to disable one of the connections, so the firewall/NAT/router knows where to send a package. Even during testing this could lead to problems.

I did the ping test and it timed out, I added the custom rule and restarted the firewall and also restarted the router but nothing seem changed.Though I don't know how to verify if the ttl change was a succes or not.

I dissabled the ethernet but still nothing sadly

Even ping 8.8.8.8 time out?

Yes both the google and the 8.8.8.8 timed out

Really don't know. But at least you should disconnect Ethernet or repeater.

They cannot get the same IP.

Currently I am only using the repeater
