Noticed the RBI router had a different colour light for the connection. Figured 4g had come to my local tower.

Wiredly been following http://community.vodafone.co.nz/t5/Network-status/PLANNED-MAINTENANCE-Mobile/td-p/172190 closly, But no offical notice of "Tai Tapu" tower being upgraded.

But the map on  http://www.vodafone.co.nz/broadband/rural/ now shows 4g in my area (changed in the last 10 days)

House is wired with an external RBI antenna, so was surprised to find speed tests being affected.

But when running in 4g mode or "LTE prefered", the speeds for downloads is slower but upload is better, see below. Any thoughts on what could be going on here?
