I’m re-arranging my setup and wanted to make sure this will work. I’m planning on buying a new modem and a new wireless router to (a) stop paying $10 a month for my Xfinity one (Arris TG862G) and (b) improve the strength and speed of my Wi-Fi. Most of my heavy use will be with wired connections, and Wi-Fi will be a couple of iPhones browsing and sometimes streaming from the DVR, etc. We have Triple Play but don’t use the phone.

For the modem, I was looking at the Arris SB6183 which lists speeds of up to 686 Mbps (I’m paying for 150 right now). For the router, probably an AC1200 C5 or C1200 Archer or something similar, not too worried as heaviest use is wired, just want to make sure it has 10/100/1000 ports on it.

My Mac and my router will be about 20’ from most of the other devices, such as TV, Xbox, and WDTV, as I want to move the router to a more central location to fix some weak spots. I’ll probably put the modem with the router, just to get rid of one run of cable. So I’ll have:

> Coax into modem
> Ethernet from modem to wireless router
> Ethernet from router to Mac (~3’ away)
> Ethernet from router to a switch in my entertainment center (~20’ away)
> Ethernet from switch to TV, Xbox, WDTV, and an older Airport Express, which I’m just using in wired mode for Airplay (Airplay was spotty before over Wi-Fi so just going to use it wired)

Does the switch affect performance much? I will usually not be using more than one of the items connected to the switch at once, so I was hoping that will help prevent problems/slow speeds.

Is there any particular port on the router that should be connected to the switch? Some of them say 1 WAN and 4 LAN (or vice versa?) but wasn’t sure if the ports differed at all.

Any other issues that might come from this setup? Years ago I had problems using my own modem instead of the Comcast one, but I’m hoping things are smoother now.

And just as a question...for router Wi-Fi speeds, the listed speeds are way higher than my ISP plan of 150 Mbps. Is any speed over 150 Mbps just overkill?

Thanks for the help!

 
Solution
any gigabit switch with enough ports will work.

switch needs to be connected to any of the 4 LAN ports on the router.

when it comes to content coming from the internet (cloud) any speed over 150Mbps is overkill. however sounds like you will be streaming content coming from the local network (content streaming from DVR) in this case the extra speed will be useful, so its not overkill.

Great, thanks for the answers!

With ditching the Comcast modem/router, should I be concerned about the modem I get not being supported in the future? The model I was looking at looks pretty current (DOCSIS 3.0, 600+Mbps), so I wasn't sure if there was something that might change in the near future, leaving me with a useless modem.

Thanks!
