if the device you are telnetting from is not in the same subnet as 192.168.1.109/24, then add “ip default-gateway <gatewayIP>”command on switch.

[MHM Cisco World]

As @ammahend mention check if new vlan 1 is same subnet with your pc .

If it same and not work do

Shut/no shut the vlan1 interface 

And clear vty line all 

And try again.

Hi,

I suggest for two things. Checking basic connectivity and troubleshoot Telnet issue. 

1. Are you able to ping 192.168.1.109 from your mgmt laptop/desktop? If not, Try to add default gateway as p default-gateway <gatewayIP>. Alos, if you are managing from other location then you must have your new route.  

2. If step 1 is clear then can you check if something else as firewall or ACL on gateway is not blocking Telnet. Try with "clear vty line all" and 

line vty 0 4

transport input all

let me know status after this.
