Q: What is a VPN?

VPN stands for Virtual Private Network . A VPN creates an encrypted connection from your device to a VPN server and sends internet traffic via that server. It can be used for extra privacy or to get an IP address from another country. If you choose a Swedish VPN server, for example, you normally get a Swedish IP address. Do I need a VPN for Wifi.se? No. Mobile data, SIM and eSIM work without a VPN. You only need a VPN if you have a particular need yourself, for example a Swedish IP address for a service while you are abroad. VPN in the router or on the device? For the best performance we normally recommend a VPN directly on the phone, computer, tablet or streaming device. A VPN directly in the router can give lower speed. VPN and speed A VPN creates an encrypted tunnel between your device and a VPN server. This can give better privacy but can also reduce the speed, because the traffic has to be encrypted and sent via an extra server. So if the internet feels slow, test without the VPN as part of troubleshooting. For most users a VPN on the phone, computer or streaming device is easier to manage than a VPN directly in the router. Do not change more than necessary Router settings such as APN, DNS, network mode and VPN can affect the whole internet connection. So change one setting at a time and note the original value before you change anything. Then you can easily go back if the result gets worse. Read more: Support & help

Q: What is an IP address?

An IP address is the address used to identify an internet connection or device on a network. There are both local IP addresses and public IP addresses. Websites can use the public IP address to estimate which country the connection comes from. When roaming, the country of the IP address does not have to be the country you are in. That is why some services may sometimes think you are in another country. Two types of IP address In a home or router network, your devices usually have private IP addresses that are only used locally. At the same time, the router has a connection to the mobile operator's network. When you open the router's web interface, you normally use a local IP address and therefore need to be connected to the router's Wi-Fi or LAN. Do not change more than necessary Router settings such as APN, DNS, network mode and VPN can affect the whole internet connection. So change one setting at a time and note the original value before you change anything. Then you can easily go back if the result gets worse. If it still does not work Check the status of the service and then test one thing at a time. When you contact Wifi.se support, please tell us which router you are using, which SIM/eSIM it concerns, which country you are in and what you have already tested. That way we can start directly with the right troubleshooting step. Read more: Support & help

Q: What is DNS?

DNS works roughly like the internet's phone book. When you type a name such as wifi.se, DNS translates the name into the IP address the computer or phone needs to find the right server. If DNS has problems, the internet connection itself can work while websites do not open normally. Do not change DNS during ordinary troubleshooting unless you know why or have been given instructions. Put simply DNS translates names such as wifi.se into IP addresses the network can use. If DNS does not work, the internet connection can be active while websites still do not open. DNS is therefore a possible troubleshooting point, but should normally not be changed before simpler checks have been done. Do not change more than necessary Router settings such as APN, DNS, network mode and VPN can affect the whole internet connection. So change one setting at a time and note the original value before you change anything. Then you can easily go back if the result gets worse.

Q: What are LAN and Ethernet?

LAN means local area network. Ethernet is the ordinary cable connection used to connect a computer, TV or other device directly to the router. A cable can give a stable local connection and reduce Wi-Fi interference, but it does not change the mobile network's coverage. Do not change more than necessary Router settings such as APN, DNS, network mode and VPN can affect the whole internet connection.

Q: What is NAT?

NAT is a network function that lets several devices share the same internet connection via the router. For ordinary browsing, streaming and work you normally do not need to change NAT settings.

Do not change more than necessary Router settings such as APN, DNS, network mode and VPN can affect the whole internet connection.

Q: What is the APN?

APN stands for Access Point Name . It is the profile that tells the phone or router how to connect to the operator's data network. Think of the APN as an address to the right internet connection at the operator. If the APN is missing or wrong, the device can still show a signal and be registered on the mobile network but still have no internet. When do you need to think about the APN? When a SIM works in a phone but not in the router. When you have a signal but no internet connection. When you switch to a SIM from another operator or roaming solution. When support explicitly asks you to check the APN. On many modern devices the APN is set automatically from the SIM card. So do not change the APN unnecessarily. What the APN does APN stands for Access Point Name and tells the mobile network how the data connection should be set up. A wrong APN can mean that the router has a signal and registers on a mobile network but still has no internet. The APN is normally filled in automatically. Only change it if a Wifi.se guide or support gives a specific value. After changing the APN you should save the setting and restart the data connection or the router.

Q: Should I change the APN?

Normally you should not change the APN if the internet works. Most phones and routers read the right setting automatically from the SIM card. The APN should mainly be changed during troubleshooting, for example if you have a mobile signal but no internet connection and support has confirmed which APN value to use. Check first That the SIM card is active and has data left. That mobile data is on. When used abroad: that data roaming is on. Restart the device. If the problem persists, you can check the APN. It is best to write down the existing setting before you change anything. What the APN does APN stands for Access Point Name and tells the mobile network how the data connection should be set up.

Q: What is firmware?

Firmware is the built-in software that controls the router. Among other things, it manages the mobile network, Wi-Fi, security, lights and how the router communicates with its components. Why is the firmware updated? To fix bugs and improve stability. To improve compatibility with mobile networks and SIM cards. For security updates. For new or improved features. Do not cut the power during an ongoing update unless a Wifi.se guide explicitly says otherwise. During an update Do not switch off the router while the firmware is being updated. The device may restart automatically, and it can take a few minutes for Wi-Fi and the mobile connection to come back. If an update has just been done, wait until the router has fully started before you begin troubleshooting.
