RV220W local host (wired or wireless) to wireless host failing until reboot

Unanswered Question

I have configurations set to not enable wireless isolation.

I have configured the wireless vlan# to be the same as the primary production vlan#.

I can ping both wireless hosts from the router, but cannot ping from host to host (making it look like wireless isolation is in fact in effect).


(client1 is an ipad) (from router 192.168.70.1)

    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),


Client#2 and client#1 are reporting similar IPv4 configs. Default gateway is 192.168.70.1 (the router), DHCP was successful, netmask matches.


Security mode on the wireless IS set (WPA2), but the checkbox for wireless isolation is not checked.

Firewall IS enabled, and rules are set for specific vlans (two ports have been allocated for two other vlans, and there are rules for talking between the vlans. I cannot set an 'allow any' rule for talking within a vlan (but shouldn't need to).

In this instance: vlan1 has a network on it (wired only) on port 4. Vlan 111 has a network on it (wired only) on port 3. Ports 1, 2, and the wireless SSID configured are all set for vlan70.


router is running current (I think) firmware:

PID VID     RV220W-A V01

Current Firmware Version     1.0.4.17


Issuing a reboot (and making no other changes) suddenly has it work... at least for a little while.

I first found this problem with a network printer. Everything was great, but I usually couldn't connect to it. Occasionally a few pings would sneak through, but generally even though it was reachable from the router, no one else could reach it (wired or wireless) from vlan 70. A reboot made it reachable, though it failed not long after. I fixed it in that case by moving the printer to a wired connection, but that is a crap solution.

Is wireless isolation something that just suddenly starts happening (isolating any given wirelessly connected host from others on its segment) over time? If so, that's a heck of a bug.

I think you may have misread. The devices are authenticating, they can always reach internet hosts. What they can't do is reach other hosts on the same subnet. If it was a WPA2 or passphrase issue, I would not be able to freely reach outside websites, games, servers, etc.


The issue is that after an uncertain interval, wireless hosts will no longer talk (within the same subnet) to other wireless or wired hosts. They retain outside access, etc. Rebooting the router, with no other configuration changes, restores their ability to talk host to host in the same subnet(for instance, to access a NAS connected by rj45. Or a printer).

Nothing in your linked resource even comes close to addressing this, and seems entirely focused on resolving interference, poor signal, or compatibility across standards.
