I live in Deerfield, Illinois. My rent term is 18 months. I want to sublet after 12 months. My landlord said no. Under the law, am I legally allow to sublet?

Here is the term in my contract: 'Tenant will neither assign this lease nor sublet the premises without prior written consent of Landlord; such consent will not be unreasonably withheld. Landlord's consent in this instance will not waive Landlord's right to refuse subsequent assignments or sublettings nor will Landlord's consent release Tenant from liability under this lease.'

Suppose I find good credit subtenant, can my landlord refuse my sublet?

Thanks

Edit: I have made 2 complaints about noise coming from the neighbors.

Update: The company that manages the property told me that tenant can only move in for a 12 month period and my sublease is only for 6 months. This is not in my contract with the landlord. How can I still sublet?
