Hi guys I am jumping into my first true server setup. I will most likely buying a ibm x3650m1 but I am unsure of what I should do for WiFi. The system will be used as a storage server and plex streamer and 3 of the computers are WiFi and 3 can run cat6. My question is would the best setup be buying a gigabit router and running a access point if that?
I am unsure of how access points work but the WiFi devices need to be on the same network as the router for plex to work.
You might be best to buy a gigabit router and use it as an access point (no DHCP). The cost difference is about the same and at least the router is built for supporting multiple devices and will probably be easier to set up with less points of failure (hardware support).
depending on the router you can sometimes turn the WAN port into another LAN port giving you 5 total, but that would be something buried in the settings somewhere. Getting one with more than 4 might not be easy though. Gigabit desk switches are cheap, probably around $15.
Most Routers with Wifi I know do not have more than 4 Ethernet ports. I'd opt for a combination of a simple switch and a wifi access point. If you do not let the AP do it's own DHCP all it's wireless clients will be in the same subnet as the fileserver. Plus: You can wall mount or ceiling mount most APs for better range.
