I have two Roku boxes, one is the original model and the second is a Roku HD, Model 2050X. I currently have a Netgear wireless router (WNR2000, N300) that I use to connect to both the Roku, an Acer laptop computer, and my wife has a Blackberry Playbook. In general, everything connects OK, but at times it seems that the computer and Playbook slow down a bit and things I'm streaming on Roku sometimes 're-load' at a lower quality rate. I have Suddenlink cable Internet, with an advertised speed of 10 mbps (although most of my speed tests show in the 7-8 mbps range).
I've been trying to educate myself on dual-band routers, and from what I gather, 'older stuff' connects on the 2.4 GHz band and 'newer stuff' connects on the 5 GHz band. Can someone answer these questions, please:
1. What is the connection speed (if that's the correct term?) of the two (older) Roku boxes that I own. Do they connect at 802.11n on the 2.4 GHz band, because I have a N300 router? Or, do they connect at 802.11b/g, because that's all that they're capable of? Or,__________?
2. It seems that the newer Roku boxes connect at 802.11n (but are backwards-compatible to b/g). Does this mean that if I had a dual-band router, they would connect on the 5 GHz band? Or would they still us the 2.4 GHz band?
3. If I were to upgrade to a dual-band router---and if necessary to a newer Roku box because the two that I presently own are not capable of using the 5 GHZ band to connect at 802.11n---is the consensus that I would see an improvement?
4. Or am I limited to whatever is coming over my cable Internet coax, and upgrading to a dual-band router (even one with a higher speed such as 450) would likely do nothing.
Any information or opinions would be appreciated. I realize that I may not be understanding all this correctly, and need to do some more homework.
