You'll need to utilize the official WARP client if you want to guarantee stability and avoid this.

This is a known issue with wgcfwgcf that lots of people experience - it's an unofficial implementation not endorsed by Cloudflare, so you'll consequently hit (undocumented) abuse prevention techniques that Cloudflare have in place.

Can I share the adapter to my router

Is there a way to do so when I connect to the warp client does it create a network adapter to share the connection?

Yes, it's possible to do this. If your router allows you to route traffic through a WireGuard client, it's fairly trivial to set this up. I've only ever done it on Linux though, I have no experience with Windows.

There's probably a handful of different ways to achieve this, but on Linux, if you install WireGuard on the same machine as the official WARP client, you can configure a WireGuard interface on the machine and configure a postuppostup iptables rule to use NAT and route all traffic through the CloudflareWARPCloudflareWARP interface.

Then connect your router to your own WireGuard server and you'll be routing all your traffic through WARP, and you should mitigate the issues with wgcf
