r6230 wireless router preventing communication between wireless devices?

It's not a bad thing that all of my wireless devices are isolated from each other, but I have a situation where I need my iphone to be able to communicate with my wireless roku player.  My Roku app on my iPhone is only detecting my wired Roku.  No sign of my other two wireless Rokus.  I'm 99% positive my router is preventing the communication.  I've done some basic ping tests to devices I know should normally respond to pings and I'm coming up empty every time.

 

Is there a special setting in the router that I need to allow for this?  I believe I've seen it in other models that I've managed.

 

Apologize if this has been asked before, my search has come up empty.  Thanks in advance!

   Firmware version?  Connected to what?  Any other routers, or
extenders, or similar?

   The evidence behind your conclusion would be much more interesting
than your conclusion itself.

   "I've done some basic ping tests" or "coming up empty" is not a
useful problem description.  It does not say what you did.  It does not
say what happened when you did it.  As usual, showing actual actions
(commands) with their actual results (error messages, LED indicators,
...) can be more helpful than vague descriptions or interpretations.

 

   "ping tests" from what to what?  Actual IP addresses, commands,
results?  Copy+paste is your friend.

   Unless a "guest network" is involved, any device on your LAN should
be able to communicate with any other.  Anything else would be a defect.
Of course, "defective" and "impossible" are spelled differently for a
reason.

Re: r6230 wireless router preventing communication between wireless devices?

@antinode here are my specs:
V1.1.0.86_1.0.1
Single 2.4Ghz SSID with WPA2-PSK[AES]
My laptop: 192.168.1.2
My wireless roku: 192.168.1.34
My iphone: 192.168.1.38
 
None of these devices can ping each other when connected to this SSID.  Output from laptop:
Pinging 192.168.1.34 with 32 bytes of data
Reply from 192.168.1.2: Destination host unreachable.

Further test, I just took my work phone and turned it into a hotspot.  I then connected my three test devices to that.  What I was trying to accomplish worked:  my iphone could communicate with the roku without issue.  I could also ping the roku from my laptop.
My laptop: 172.20.10.2
My wireless roku: 172.20.10.14
My iphone: 172.20.10.7
 
Ping results from laptop to roku:
Pinging 172.20.10.14 with 32 bytes of data
Reply from 172.20.10.14: bytes=32 time=4ms TTL=64
Reply from 172.20.10.14: bytes=32 time=7ms TTL=64
 
From past experience I have found that it is not always true that wireless LAN clients have the ability to communicate with each other.  The Cisco Meraki offers a "Layer 2 LAN isolation feature."  Similarly Aruba offers the "Deny Inter User Bridging" command.

   Ok, but those are not Netgear R6230 routers.  So far as I know, on an
R6230, only the "guest network" feature provides (or should provide)
anything like that kind of filtering.

   I'd expect "Destination host unreachable" if there were some routing
problem, but your IP addresses look reasonable to me.  (Unless you have
a strange subnet mask somewhere, which seems unlikely.

 

   The usual first step when the actual behavior does not match the
expected/documented behavior is a settings reset and a manual
reconfiguration.  When that fails, I'd try a different firmware version.


   Note that there's a "Version 1.1.0.92 - Hot Fix" available.

 

   Visit http://netgear.com/support , put in your model number, and look
for Downloads.  (For older versions, under Firmware and Software
Downloads, look for "View Previous Versions".)  Find the kit(s).
Download the kit(s) you want.  Read the "Release Notes" file for
instructions.

 

   Are you beyond the free period for official Netgear support?

I discovered this afternoon that this problem is not present on my 5.0ghz SSID.  It's strictly with my 2.4ghz.  I had been using 2.4 for the roku because I thought that distance was going to be an issue.
