Is a full on router really needed with the modem doing DHCP ?

  • Doesn't Need an Answer
So, I was thinking.. Do we really NEED a router ? Wouldn't a switch be good enough, for people without wireless devices for now  ?  Since the modem will do DHCP.  I never tried just a switch, but the last time I had to do something like that I was using a BEFSR41 that was messing up as a router.. But would work fine if I put all wired devices in the ports (used as a switch) , however, the computers couldn't see each other across the network, thus no file/printer sharing.

I'm going to assume a proper switch would do the same thing as the BEFSR41 after the DHCP from the modem ?  IE: different IP#'s from the modem for each machine internal and external ?

I'm not sure about the Surfbeam2 modem, but it's predecessor would only issue one DHCP address, so a switch would "work" as long as only one computer was on at a time.

Not sure why you would not want a wireless router. Some are relatively inexpensive and have at leasst 4 ports on the back for your wired devices. This would give you the (future) option of introducing wireless devices (printer, Ipads, laptop, smart phones, ...)later on or provide internet access to guests who have such devices. If you go this route - make sure you "lock down" your wireless side with a decent password.

I turn the wireless off unless I need it.  I don't want the added RF in the house, SMART power meters are bad enough without me adding to it.

....  If you think 2.4Ghz and 5.0Ghz are bothering you, then that massive 10Ghz and higher beam that satellites use blasting down, as well as all OTA and Radio stations are also bothering you.

I've always found wearing a spaghetti colander to be helpful while also keeping my head well ventilated...

But seriously, it all depends on whether the Exede DHCP server will assign more than one IP address when using a switch (one way to find out I guess) - best to have firewall enabled on each device in that case. 

Otherwise, it's Network Address Translation within the router that allows sharing a single connection.

Really at $20 for a el cheapo router, and $45 for a Mikrotik Routerboard (RB951) product instead .. I can't see paying $5-10 for a switch either.
