Setting up Linksys EA2700 with Sky SR102

Hi,

I would appreciate any help to setup the EA2700 (should be delivered this week) with an existing SR102. The thinking behind this was to improve the LAN and Wifi connections.

I know I only have broadband but it works pretty well and don't feel I need the download speeds of fibre yet.

I've recently read the security on Linksys routers isn't great, is there a work around for this?

I have a synology nas drive currently accessible via port forwarding and would like to do the same again if possible unless there is an alternative?

Thanks in advance,
