Common Wired Internet Problems and their Solutions

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

Before doing anything

It's recommended that you try going onto our web page (internetas.vub.lt) before trying to fix your connection or contacting us. This might seem illogical, because, usually, when there's no internet, you can't reach anything, but this page is special, it should be accessible at all times, if you can't reach it - this might indicate either a hardware problem (broken wire, connector) or a problem with your device.

I have an active plan, but don't get any internet

First you need to check if you have an activated device, you can do that by connecting your device with the wired connection and going to our web page (internetas.vub.lt), if you get an ip address that doesn't start with 10.250.29 - the problem isn't related to activation, continue reading this guide, if it is - activate your device again.

Read ConnectingWired for more info about activation.

I have an active plan, an activated device and still don't get any internet.

The first thing you should check is whether you can reach our web page (internetas.vub.lt).

If you can't, first try replacing your internet cable and/or plugging it into a different socket, if there any available. if that helps - either your cable or the internet socket in your room is broken, if it's the cable - you'll have to buy yourself a new one as students usually provide the internet cables themselves, if it's the socket - write a problem report.

If you still don't get any connection - try looking over your computer's internet settings, both the IP address and the DNS should be gotten automatically from us.

How to do that on Windows:

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 (Ethernet) 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.

How to do that on MAC OS:

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.

Afterwards it's important that you try disconnecting and reconnecting your cable.

If you still don't get any internet service - check your IP address and fill out a problem report, it's important that you include your IP address in the problem report.

You can check your address like this:

Windows:

1. Click the search icon on your task bar.
2. Enter CMD, a program named Command Prompt should pop up - click it.
3. Write ipconfig /all and press enter.
4. Look for an entry labeled Ethernet adapter Ethernet, under it there should be a field named IPv4 address, this is your IP address - write it down or, better yet, take a screenshot of the Ethernet adapter Ethernet entry.

If you can't find an entry like this or it doesn't contain an IPv4 address - there's probably something wrong with your device.

MAC OS:

1. Click on the Apple icon on the upper-left corner of the screen.
2. Scroll down and select System Preferences.
3. Click Network. This should be on the third row.
4. Select Ethernet (wired) (The connection you are using will say Connected next to it). Your IP address will be listed directly beneath your connection status, in smaller print.
5. Write your IP address down or take a screenshot of this window.

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

This might indicate two things:

1. Your computer is misconfigured.
2. Our hardware is failing in some way.

Before writing a report, read the last section about I have an active plan, an activated device and still don't get any internet. If you still get this error even after reconfiguring your device - fill out a problem report.

Losing internet for a few seconds/minutes chronically.

Firstly, check whether your internet wire is not damaged.

If it is - replace it and check if the problem repeats.

If it still does - plug in your wire into a different internet socket, the one you're using might be damaged. If the problem disappears - fill out a problem report about a broken socket, we'll replace it.

If the problem still persists - fill out a problem report, this problem isn't that hard to fix, usually.

How to check your IP and MAC address

You can check your address like this:

Windows:

1. Click the search icon on your task bar.
2. Enter CMD, a program named Command Prompt should pop up - click it.
3. Write ipconfig /all and press enter.
4. Look for an entry labeled Ethernet adapter Ethernet, under it there should be two fields named IPv4 address and Physical Address, the first one is your IP address and the other one is your MAC address, write them down.

If you can't find an entry like this or it doesn't contain an IPv4/Physical address - there's probably something wrong with your device.

MAC OS:

1. Click on the Apple icon on the upper-left corner of the screen.
2. Scroll down and select System Preferences.
3. Click Network. This should be on the third row.
4. Select Ethernet (wired) (The connection you are using will say Connected next to it). Your IP address will be listed directly beneath your connection status, in smaller print.
5. Write your IP address down or take a screenshot of this window.
6. The MAC address will be in the advanced menu, you can access it by clicking the advanced button below.
7. Go to the Hardware or Ethernet tab and there you will see your MAC address, write it down.
