I got 4G home broadband from Three UK about 11 months ago. Initially I was consistently getting good speeds of around 35-40Mbps. A few few months ago the connection speed dropped on my Huawei AI Cube and after trying out a number of things I eventually got a TP-Link MR600 coupled with a Poynting XPOL-2 antenna that I mounted in my loft. I used my phone to find the best position and direction of the antenna, which I confirmed with the admin portal of my router to make sure I was getting the best signal.
Initially this resolved my internet issues, but I've noticed again recently that my connection speed has gotten inconsistent again - sometimes I get speeds of over 40Mbps, but at peak times or in adverse weather conditions it can swing as lower than 10Mbps. I also notice at times I get really bad pings - usually if you check a moment later the ping goes back to normal, but I think it's enough to throw some internet services. Really I'd be quite happy if I could just keep a more consistent minimum speed of around 25Mbps and a more reliable ping. I'm now thinking of getting the antenna professionally installed on the outside of my house.
My question is two fold - before I spend money on a professional install, does anyone have any advice of anything else I should try first? Looking around, I could only find sat-works.com that provided an install service - does anyone else know of any other companies they would recommend?
