I hope so for your sake. I love it when you can get great stuff which doesn't cost an arm and a leg. Everyone loves to take the **** out of me for being a Linksys fan boy but that is because I started out 15 years ago with a Linksys/Cisco router which was great at the time and I never looked back. As technology has moved on over the last 15 years I updated my routers to keep up with the wireless and wan to lan throughput as I have always been on VM's highest tier. I have always had Linksys routers and each one has worked flawlessly and I have never had any dodgy lockups and needed to reboot. I have got a semi-demanding network in the house and I stream an awful lot of stuff between two nas servers and the tvs and we stream a lot of youtube content to the tv downstairs. I have got a networked laser printer in one room, Sky boxes in other rooms where we watch a lot of on demand stuff and that is without all the wireless from the tablets and phones. When you do a lot of stuff which all revolves potentially one device (your main router) then you want something which has great wireless, great performance, great reliability and you know it isn't going to let you down.
Each one of my Linksys routers has ticked those boxes over the years and until they do something to screw it up I'll continue buying Linksys routers out of brand loyalty. I see too many people come on this forum complaining about wireless speed, wireless range, wan to lan throughput, routers locking up and loads of other stuff (way too many dns issues), all of which can and could be avoided if they just brought a decent router.
The EA6300 does about 800mbits want to lan and then you have got ac wireless as well. I think it will be a perfectly solid router for you with ample future proofing.
I have dug out my trusty network diagram so you can see how important it is to have something which you can rely on and that you know is going to work:
I feel like a right spoon, having just looked at my diagram I have noticed that I have got a 6300 myself. It is setup as a switch and wireless access point atm. I bought it last summer because I needed to use it as a print server because the laser printer I had at the time was usb only but it has since been replaced with a proper network printer. Mine was £75 when I bought it in May last year so I think £50 is a very reasonable price for something which is very very good.
