mohammed Please contact our support 0800 707 707 team for a detailed analysis of your issue. We cannot make any further changes from here.
Please note that the modem assigns IPv6 addresses. If your network card is only set to IPv4, it will not receive an IPv6 address.
Here you can see, for example, that two of your devices that are online are using IPv4 and IPv6.
