It's a big no no, in my books unfortunately - Always get permission and in writing.
As the Landlord and Freeholder to a number of properties, i make it clear in our contracts that you are not to install any new Broadband / Satellite infrastructure without my consent. This is honestly down to just poor experience with the likes of Sky and Virgin Media engineers / contractors in the past when they've damaged the property when drilling into living rooms etc. Indeed, it also extends to situations where my units are not in a Freehold owned by myself and the 3rd Party Property management firm has it's own rules about what you drill into the external building.
However - I insist and believe it is a right to have access to decent quality broadband so where available i will almost always consent to having FTTP installed etc by BT etc, and i have had it installed through Openreach's Network in Advance service in certain areas. I just make sure i have one of my team there to supervise any install and to make sure any 'damage' is made good or touched up.
As you're only in this contract for 9 months, i would hate to hear that you'd lost your deposit if the landlord finds out and has a fit you didn't consult them or at worst, 6 months down the line they inspect / relist the property and kick you out for breach of contract.
Don't ask, don't get but for goodness sake get it in writing!
