Razer Blade 15 Advanced 5GHz wifi connectivity issues

Hi all, Apologies if this has been answered elsewhere, I'd be grateful if someone could direct me to the reply. I have recently purchased a Razer Blade 15 1070 Max Q design and I am having connectivity issues when I try to connect to 5GHz wifi. The adapter fails to connect and automatically reconnects to the 2GHz signal. I have updated the wifi adapter drivers today (22-02-2019). Is there anything else I can try? Thank you.
