One user faces an issue: when he is connected via LTE (his laptop has internal modem) the CheckPoint VPN Client gives him an error:&nbsp;no network detected. Once the user switched to WiFi - everything works. What could be a problem?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="MicrosoftTeams-image.png" style="width: 540px;"><img src="https://community.checkpoint.com/t5/image/serverpage/image-id/17409i9D6050DF9DC2B041/image-size/large?v=v2&amp;px=999" role="button" title="MicrosoftTeams-image.png" alt="MicrosoftTeams-image.png" /></span></P> Wed, 10 Aug 2022 16:23:41 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154851#M26317 Exonix 2022-08-10T16:23:41Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154856#M26320 <P>VPN clients such as ours attach to the network driver.<BR />I'm guessing your LTE modem uses a network driver that we don't recognize or support.<BR />In which case, you would get "no network detected" as there isn't a NIC it can utilize the right way.<BR />You can try opening a TAC case, but I suspect this is an RFE.&nbsp;</P> Wed, 10 Aug 2022 20:07:18 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154856#M26320 PhoneBoy 2022-08-10T20:07:18Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154864#M26322 <P>Is the LTE connectivity IPv4 or IPv6?</P> Wed, 10 Aug 2022 23:17:46 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154864#M26322 Chris_Atkinson 2022-08-10T23:17:46Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154865#M26323 <P>That's actually a good point.<BR />If the connection is IPv6 only, it will not work as the VPN client does not support IPv6 at all.<BR />That is most definitely an RFE.<BR /><BR /></P> Thu, 11 Aug 2022 02:33:25 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154865#M26323 PhoneBoy 2022-08-11T02:33:25Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154883#M26327 <P>The user said, it works from time to time. So, this isn't CheckPoint issue. But it is good to know about IPv6. thank you!</P> Thu, 11 Aug 2022 10:19:56 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154883#M26327 Exonix 2022-08-11T10:19:56Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154944#M26343 <P>I have faced similar issue and issue was with IPv6 only in the provider domain/network.<BR />Checkpoint client does not support IPv6.</P><P>So what we did, we requested the users to connect with IPv4 provider's network via VPN (Sometime disabling IPv6 at client machine).</P> Fri, 12 Aug 2022 10:42:34 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/no-network-detected/m-p/154944#M26343 Hasnain_Ansari 2022-08-12T10:42:34Z
