Interface status showing as 100Mbps Full Duplex
Fabin Newbie ✭
I'm using TZ400 firewall. We are using four internet connection that provides 200mbps+ speed. But the interface X1, X2 are showing the port status as "100Mbps Full Duplex" and getting a lower speed below 100mbps. ( But if connected directly to a laptop without going through the firewall, we are able to get 200Mbps speed ). The other interfaces show "1Gbps Full Duplex" and are able to get high-speed internet.
The Link Speed for X1, X2 are set as Auto-Negotiate.
I tried changing the cables to Cat 5E ones. Still, it shows "100MbpsFull Duplex". How can I get it to "1Gbps Full Duplex"?

the only two things I see here is to set X1 to "1 Gbps - Full-Dupley" manually on the Interfaces Advanced Tab and if this does not do the trick, try to put a 1 Gbps switch between the X1 Interface and your Router.
Auto-Negotiation can be tricky sometimes.
Most of this kind of the issue due to the ISP side. Recently i faced the same issue due to they configure the Fiber ONT data port with voice . So the same port if i use for pabx it will work as well data and I am getting half of the internet speed.
