Why does my ipad's location is in Lithuania when I live in the US?

When using a VPN, the estimated location will derive from the IP Address of the VPN exit to the Internet. This VPN Gateway may be in another country.

If you disable your VPN connection, you may see different results.

Depending upon how you are using your VPN, it may not be providing the additional privacy and security that you might expect. Your VPN does not provide end-to-privacy; it only provides additional security between you and the VPN operator (useful in providing additional security over public WiFi networks) - but provides absolutely no additional security between the VPN Gateway and onward Internet connection.

I’d make an educated guess that you perhaps have a WiFi Only model iPad. Are you using a VPN connection?

Unlike your iPhone and WiFi & Cellular models of iPad, WiFi Only iPads do not have any GPS location capability with which to directly determine their location - and as such are completely reliant upon their network connection to infer an approximate location.

Without benefit of GPS, your approximate geographic location is inferred from a “database lookup” of (a) your WiFi Network Name (SSID) or detected neighbouring WiFi networks - and (b) the “public” IP Address provided by your Internet Service Provider (ISP). 

If the mapped WiFi network name or IP Address are not available within the applicable databases, or if this information substantially differs between sources, then your approximate location may not be computed - or may wildly inaccurate. This situation often occurs if you are in a remote/rural location where neighbouring WiFi networks are scarce - or if connecting over satellite or VPN connections.

Network IP Addresses and WiFi networks are frequently mapped in urban and cosmopolitan areas (including “crowd source” techniques) and as such approximation of your location from lookup against these databases can be provide relatively high accuracy. As population and network density diminishes, this mechanism becomes progressively less reliable.

If you can, perhaps try connecting to a different WiFi network - be it private, public or your telephone WiFi hotspot.

I hope this explanation as to possible cause is helpful.

Are you using a VPN?

Where in Safari does it appear you are in Lithuania exactly?

Websites in general will not use your GPS location, they'll use the reported location of the IP address they receive for your requests. If you are using a VPN, the VPN location will by definition not match your own.

If you are not using a VPN, then please clarify exactly where in Safari you are seeing this location.

Ditch the VPN. If you’re not using it to connect to a private corporate or school network, it’s doing nothing to protect you. Especially if you’re using it at home.
