Is 192.168.1.1 actually the D-Link? – Havegooda – 2019-09-12T17:44:22.100
@Havegooda yes sure , When I enter to this ip I get the router web – dlink – 2019-09-12T17:49:13.080
Is this a wireless router? How are you connecting, hardwire or through wireless? It's possible that the router is refusing SSH/22 connections if it's not through ethernet due to a security policy, perhaps? Can you paste the verbose output? (-v flag) – Havegooda – 2019-09-12T17:51:19.983
@Havegooda I attached ssh verbose , I connecting wireless to the router – dlink – 2019-09-12T17:59:14.127
It appears your config is only set to use a PKI cert to connect? I'd take a look at that and see if there's a way to enable user/pass authentication. That router is relatively old, so I doubt it supports PKI in the first place. – Havegooda – 2019-09-12T18:02:34.237
