Router and power line adapter advice

Need to upgrade my ancient Linksys router, set up a secure network for the house and would like to get a powerline adapter for the Blueray to stream HD movies from Netflix. We have a couple of laptops, a desktop with a local printer, Wii (wireless), and Samsung TV and Blueray that are "wireless capable" but were sold without wireless adapters (and I'd rather get powerline adapter to get quality streaming); current router is about 7 years old at least.

Don't really trust salespeople too much, would appreciate recommendations for home networking - nothing over the top, basic work and entertainment, no crazy gaming or anything. Really appreciate it, guys!

 

Why powerline adapters? Why not just run CAT 5/6 lines inside the walls?

 

Do you always answer a question with a question?

Got my answers in Silver, thanks!

 

I'm from the Platonic school of training. ;-p

In any case, I asked because power line adapters are limited in speed, though not more so than wireless. A wired connection will still offer the best speed performance. Most casual users will not notice the performance bottleneck, but if you do a lot of simultaneous streaming processes like movies, music, p2p, file transfers, real-time gaming; you will really notice it.

 

I'd be one of them casual users who won't notice and would hate drilling holes in her nice house!
