Common Wireless Internet Problems and their Solutions

It's recommended that you read the ConnectingWireless page first.

Being Unable to log in.

When logging onto VUBi Wi-Fi or VUBi Hotspot you should use the email address you used to create your VUBi Account, the credentials given to you by Vilnius University, that you might use to connect to Eduroam won't work, your password is also the password you used for your VUBi Account, that's all that you need to log in.

The first thing you should do is enter both your password and email address without using autocomplete, this is because autocomplete leaves an additional space after your credentials, so you get "vubi@…_" not "vubi@…", the system doesn't strip trailing spaces, so it rejects your username.

If you can't log onto one network - check if you're able to log onto the other or our webpage, if that's the case, you should fill out a problem report.

If you can't log onto any of our services, that might mean you mixed up your password, you can reset it on our webpage (

If you can log in at our webpage, but not onto the networks - try forgetting the Wi-Fi networks (you can usually do that by right clicking the network name on our computer or going into the network info on your phone) and reconnecting.

If even that didn't help - fill out a problem report, this usually indicates that either the Wi-Fi signal is too weak in your room or our equipment is malfunctioning.

Being able to log in, but not getting any internet afterwards.

You should first check whether your computer or phone is not misconfigured. The first thing you should check is your DNS/IP settings.


  1. Open Control Panel.
  2. Select Network and Internet.
  3. In the Network and Internet window, select Network and Sharing Center to open that applet.
  4. In the Network and Sharing Center window, select Change adapter settings.
  5. The Network Connections window lists connections to the computer. Wired connections are labeled as Ethernet or Local Area Connection, while wireless ones are labeled as Wi-Fi.
  6. Open the network connection you want to change the DNS servers for (Wi-Fi) by double-clicking or double-tapping on its icon.
  7. In the Status window, select Properties.
  8. In the Properties window, go to the This connection uses the following items section and select Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol (TCP/IP) to select the IPv4 option, or select Internet Protocol Version 6 (TCP/IPv6) to change the IPv6 DNS server settings.
  9. Select Properties.
  10. In the Internet Protocol Properties window, choose obtain DNS server addresses automatically and obtain IP addresses automatically.
  11. Select OK and close the Control Panel.


  1. Click on the Apple icon in the top-left corner of your desktop and select System Preferences.
  2. Click on Network.
  3. In the Network window, ensure you have Ethernet selected on the left-side menu.
  4. Next to Configure, select Using DHCP from the drop-down list. Click Apply.

If even that didn't help - fill out a problem report, this might mean that the Wi-Fi access point you're connecting to is malfunctioning.

Being rejected with "Can't connect to this network"

Firstly try out forgetting the network itself, if that doesn't help, try logging onto the other VUBi network (be it VUBi Wi-Fi or VUBi Hotspot).

If you're still getting rejected - try stepping outside your room and connecting there, if you succeed, that indicates a weak signal and you should fill out a problem report, if not - verify that you can't connect with other devices, if you can, this indicates a problem with your device, fill out a problem report with the exact model/internet configuration of your device and we'll look into it.

Also, if the Wi-Fi access point is accessible to you, you can try disconnecting and reconnecting it, but it is very important that you reconnect it to the same port you disconnected if from as it won't work connected to a different port.

Getting a "no more sessions allowed" error on the Hotspot network

This is a long standing problem with the Hotspot network and it's usually why we recommend using VUBi Wi-Fi instead of VUBi Hotspot. There's no way of automating the resolution of this error or for the user to fix it themselves, so the best course of action is to fill out a problem report. Sometimes this problem resolves itself after waiting for some time too.
