Thought changing/moving offices might be complicated (for someone who knows something, but is no means even close to knowing enough about networking) as needed to purchase a router, but not with the E3000.
After using a shared line (and a switch), we now had a dedicated line and had to connect PC, printer (both not Wi-Fi), couple visiting laptops, a smart phone, etc...
I needn't have stressed/worried about it as it was all so simple, straight-forward and easy-piecy with this product!
Just inserted the disc that came with the router (and 1 network cable) and it told you everything very clearly.
Couldn't be happier! :)
