i have M500, Hub3 in modem modem, using EA9500 Linksys router; and I only get 250-300Mbit download speeds; whereas if use my router at a friends who has 1GPS i get 900Mbit fine; so i know its not my router or CAT6 cables.

We have chased this with the team and they have advised that they're not aware of any known issues that may cause this slaterss, I'm happy to take another look at the equipment and connection from our side but twould need the Hub to be taken out of modem mode.
If you would like us to do this just let us know when it is in router mode and we'll take a look.
We appreciate the frustration but as everything is looking OK currently then next step is to remove any third party equipment. On your next day off, please pop the Hub back in to it's usual mode and remove the router. Post back here to let us know and we can run the checks we need to then.
