      @firefox:

      ping from pfsense 192.168.0.1 to AP 192.168.2.1 There is Ping

      ping from AP 192.168.2.1 to pfsense 192.168.0.1 no ping

      I assume this must be a typo and the ping was to the AP at 192.168.2.101?

      You need to try pinging from the AP to the pfSense OPT1 address, 192.168.2.1. That should work fine.

      @firefox:

      from pfsense to wireless client - no ping

      That's odd. The problems with the AP should not cause this. Presumably AP to wireless client is OK?

      Steve

      it is a typo my bad

      i try ping from 192.168.2.101 to 192.168.2.1 and there is a ping

      @stephenw10:

      Reading the manual for that router (wbr-3406tx) it appears there's no way to set a subnet mask or gateway for the LAN interface but it's not a problem because you can add a route manually. Adding a route is the correct way to do this, fudging the subnet is a workaround.

      In Advanced Setting: Routing: add this:

      Destination: 192.168.0.1
      Subnet mask: 255.255.255.0
      Gateway: 192.168.2.1
      Hop: 1

      Enable that and hit save. Your AP will now have a route back to the pfSense LAN subnet.

      Steve

      I tried to change and nothing worked
      I had to do hard Reset
      And configure it as before

      @doktornotor:

      @firefox:

      If I choose another option
      I will not have internet access

      The only correct option is Disable/None/whatever matching this… Not any random other option.

      @firefox:

      there is on pfsense

      That is NOT what we are talking about at all. We are talking about netmask/GW on the AP. And on that note, there should be no gateway set for LAN interfaces on pfSense!

      Apparently this piece of garbage HW would best be utilized in a dumpster.

      There is no option disable

        Getting a E1000 linksys is crazy cheap on ebay.

        When loaded with DD-WRT they will do every thing you want and more, just incase this doesn't pan out for you.

          My cousin did not need it
          So brought it to me

          If I had to buy
          Would you buy something much better

          On that note
          I'm dead tired
          I will continue with this tomorrow

            "If I had to buy

            For your purposes, its hard to do much better - Easy to spend much more money though.
            If I wanted wireless N vs G, I'd go with the E2000 - Also dirt cheap used.

            A new solution will probably not bring you any more practical utility and will cost you.

              Hmm, this is interesting but confusing.

              It is possible that it's only possible to add static routes on the WAN interface, there is no option to select the interface. However if that were the case then adding that route should have had no effect at all. I assume by your statement "nothing worked" that you were then unable to connect to the webgui at all? Seems like your router may be misbehaving somehow.

              Anyway you have yet more options! Another way to allow the access point to have a route back to LAN is to NAT between them. Now usually you wouldn't want that but it could be done with manual NAT configuation.

              The other thing you could do, and this is what I've done, is just not worry about it!  ;) I have an access point that (mis)behaves in exactly this way. It has no route back to other interfaces, I cannot add a route to it, I cannot configure a gateway on it's LAN, I can enter a fudged subnet mask but that doesn't work. So I set it up and ignore it. I probably haven't needed to check its webgui for a year or so and when I do I just connect by wifi.

                Personally, I think he should have all his connections on the LAN ports on that AP and that he should put tape over his WAN port.

                  Good Morning

                  I did a Hard Reset to AP
                  And put everything to the initial state as if he were Router

                  Then again I followed the guide to make it to AP
                  And it works as AP
                  Just the access its management interface is only when connecting Directly to him
                  wired or wireless

                  I do not know what to say
                  I tried everything I know
                  And all you know

                  Just does not work
                  I will stay with it how it is now
                  There is internet access from wireless devices

                  But not sharing files between computers on the wired network
                  To computers on the wireless network
                  Or reversed

                  It would make me crazy in the near future
                  So many thanks to everyone for the help

                  If I find why this happens I promise to update

                    Just because you can't access the AP webgui from the wired network that should not mean you can't access other wireless clients. That is some other issue. As long as you have the correct firewall rules in place in pfSense there should be access between the wired and wireless networks.

                      Unfortunately it also does not work
                      We have 5 laptops at home
                      One currently running and is with me
                      Has two shared folders

                      They are accessible only if the computer is connected to the wired network

                      Of course the same thing
                      But the reverse

                      No wireless devices access to the wired network shared directories

                        Ok, a number of things could be happening here:
                        pfSense is blocking the traffic. That's easy to check because it will appear in the firewall logs.
                        There's a routing problem. This doesn't appear anywhere so it's harder to spot but we've just spent a good deal of time checking out the routing on your network and it looks good.
                        Something is blocking the traffic locally. E.g. Windows firewall is blocking access because the traffic is coming from another subnet.

                        Remind me, you are not able to ping between wired and wireless clients either?

                          Yes

                          Specific computers that I am trying to access shared folders
                          Are running Linux Ubuntu

                            Ah, er, yes you're not able to ping or yes you are able to ping?  ;)

                            If you plug a client into one of the other LAN ports on the wbr-3406 can you ping the wired clients (on 192.168.0.X) from there? That should exclude and wifi weirdness from the problem.

                              from wireless computer 192.168.2.8 to wired computer 192.168.0.2
                              and
                              from wired computer 192.168.0.2 to wireless computer 192.168.2.8

                                Ok so you can ping but not do file transfer? And this worked ok before?

                                This is probably because the machines are not on the same subnet so they are not directly discoverable by Windows (or whatever). Have you tried accessing the shared folder directly by its IP?

                                  If you don't know how to access a share by IP, its easy in windows…

                                  hit start > computer

                                  on left side, click network

                                  select your current computer in the list

                                  now in that bar at top of file browser, put in \192.168.1.30  (or whatever the IP of the computer with the share is)

                                  I'm slipping - I should have suggested this way way back but "shares" was never mentioned early on.

                                    Just now I tried to access a network folder
                                    Using ip number

                                    It work

                                    Why not see all computers when entering the network

                                      File sharing uses broadcasts that don't cross subnets to advertise themselves.

                                      So, when you have files and printers shared, the easy way to reach them across subnets is by IP since no broadcast is required that way.

                                      Understand?

                                      If I had known you had shares, I would have suggested it earlier.  Good thing stephenw10 did.

                                        If you have a domain controller/WINS server that can register connected clients then you can span subnets I believe, not my area.

                                        If you have enabled "Register DHCP leases in DNS forwarder" then you can access remote machines by their host name but they still won't be discoverable.

                                        You may be able to get discovery to work across the subnets using the IGMP proxy, I've never tried that.

                                          Can I assume that the problem
                                          Related to the same reason that you can not access the management interface of the AP

                                          I'm still trying to check why this is happening and fix it
                                          But not urgent
                                          As before

                                          If I run into something on the way so I check and try

                                          At least I have access to shared folders
                                          As you have shown me

                                            It's two distinct problems:

                                            You can't access the wifi router because it's not possible to give it a route back to the LAN side subnet.

                                            You can't see the wifi clients from the wired network because because the protocol Windows uses to discover network shares doesn't span subnets.

                                            I would try adding the route again to the access point. I should do nothing or fix it. The fact that it killed everything last time you tried it implies something wasn't right.
