DGND3700v2 no local LAN access from wifi
Hi all
I recently collected one of the DGND3700v2 devices and set it up at home. I did a basic config, changed the LAN IP range to match the existing LAN devices, configured DHCP, got the Internet DSL line up and running and configured the 2.4Gig radio with WPA2. Everything works fine, all devices on the network (wired and wireless) can connect to the internet as expected, however (and it's a big however).. No device connected via the wifi connection can access anything on the LAN other than the router itself. I have tried from both a Mac and a Win7 laptop. They can both access the router, can access the internet, but cannot access any of the other devices on the network (Media streamer and a Tivo). Both these devices are connected directly to the ethernet ports of the router. If I plug any of the laptops into the router on a wired connection they work fine.
It's almost like the router is running some half wifi isolation allowing me only access to the router, but no other stations on the LAN. I did try to switch isolation on and off, but no change.
To test this I connected a second AP to a port on the router and set up a second SSID on the separate AP. Connecting the laptops to this SSID, which then runs wired to the 3700 and all is working again. Full access to everything.
Anyone had anything similar?? It's starting to sound like a bug to me. We are not talking a complex setup here. Firmware is 1.1.0.8 as shipped. Can't find anything newer (I'm outside the US)
Thanks

Re: DGND3700v2 no local LAN access from wifi

Re: DGND3700v2 no local LAN access from wifi
I even tried to setup a guest wifi and specifically tick the local access box, but the behaviour is the same.
My DG834 worked just fine for years and I'd toss this one were it not that I need the higher wireless speeds.

Re: DGND3700v2 no local LAN access from wifi
Some of the devices attached to the router (wired) do not appear in the attached devices list at all until I ping them from the router. Then they appear with name and all. I still can't ping or access them from the wireless network, but I can, and always have been able to access them from a wired device.
I have an 8 port Netgear switch for the rest of the devices and some of these also appear in the table, but are also not ping-able from the wifi. Disconnecting this switch has no effect either.
It's looking like it could be an arp issue. I ran Wireshark and filtered on arp's. I can see the macbook broadcast for the mac address of the device being pinged. Nobody replies. Then the Netgear, who has the device physically attached to it, arps for the mac of the very same device. This mac should be in it's own mac table since the router can ping this same device. I assume the "attached devices" table is basically the routers arp table, however, if I ping the device, get it to appear in the attached devices table, I still cannot ping it from wifi. Remember, this device can all along access the internet and can be accessed from the wired network. Very odd.
I'm going to run the same test on a wired connection now. Just need to collect some more cables...

Re: DGND3700v2 no local LAN access from wifi
I am new to this forum and I guess I came here as many others in order to find some help....
I confirm the same issue as andref with my DGND3700v2 running the shipped firmware V1.1.00.08_1.00.08 . This is happening with my Android-tablet (Acer Iconia A500 running ICS 4.03) but if use my Android-phone running Gingerbread, everything works and I can see all other devices on the network.
I am getting nuts and I have tried enabling and then disabling again Wireless isolation but this does not help. I have reset the router and then re-installed all again but in vain.
When my Acer is connected, I can use Internet but I can't access any other wired resources in my LAN such as other PC, satellite-receivers etc. It is just like it was on a different network.
EDIT: just noted that if I connect my Android-phone (which does work), then my Acer can see it. It seems like my Acer can only see devices which are connected with WIFI and not LAN.
If connect my Acer to an Access Point which in turn is connected by wire to a small switch/router, then my Acer can see all devices. It is only when it connected directly to the DGND3700v2 in WIFI, it remains "isolated".
So my results seem similar to those of Andref except for when using my Android-phone which runs Gingerbread and not Ice Cream Sandwish. Perhaps it is a problem with ICS and the DGND3700v2 although this does not explain why things do not work for Andref unless he was trying a ANdroid-device with ICS too.
Any ideas? Shall I contact support? As things are standing now, this router is pretty useless for me. I bought it yesterday and I believe I have the right for a refund.

Re: DGND3700v2 no local LAN access from wifi
Also, just like moster67, I have a switch and a second AP at the other end of the house. Devices connected to the second AP work fine and can see everything.
Interestingly unlike moster67, my android phone, also running Gingerbread behaves like the laptops and cannot see the wired devices.
I have logged a call with Netgear and was told to default the device and test with the shipped wifi settings. I have defaulted the device, but at least needed to change IP range to match the rest of the network. Needless to say, no change.
Awaiting further feedback...

Re: DGND3700v2 no local LAN access from wifi
When i make a wireshark trace, i can see that no arp response come to my wifi connected PC.
On some wifi devices (android phones for example), they say that they can't get an ip address from my dhcp server (connected by wire on LAN).
I would like to know what can i do to resolve it...

Re: DGND3700v2 no local LAN access from wifi
My routers are with 2 different firmwares (V1.1.00.09_1.00.09 et V1.1.00.08_1.00.08) and i have exactly the same problems.
My PC get an ip address by DHCP 192.168.1.144/255.25.0.0 (dhcp is disabled on the router ; it's a server on my LAN, that i can't ping, that gives me the address so dhcp broadcast/answer is ok on that wifi network).
The netgear router is configured with 192.168.0.5/255.255.0.0.
The server on my LAN is configured with 192.168.0.8/255.255.0.0 but it's the same problem with other devices on LAN (other router, network printer, ...) configured with 192.168.0.xx or 192.168.1.XX/255.255.0.0 address.
I just opened a ticket at my.netgear.com...

Re: DGND3700v2 no local LAN access from wifi
If i check/apply or uncheck the box "enable wireless isolation", the result is the same.
If i define my default gateway to be the ADSL netgear router, i can ping router and surf on Internet if my dns server is 8.8.8.8 (google dns) or the routeur himself for example.
If i try to communicate with local machines on my network (other computers, printers, other gateways), i can't and i have no ARP response.
I hope netgear support will give me a solution...

Re: DGND3700v2 no local LAN access from wifi
I just did the upgrade on my routers and the wifi connection works now, that's right.
I will see in the next hours if it is still good.
With firmware 1.00.08 and 1.00.09, i also tried to have a look at router debug mode (with 192.168.1.1/setup.cgi?todo=debug you can activate debug and telnet on the router where you got a unix like system) but i don't see any thing that could explain the problem.
And i actually had no answer from netgear support (1st level)...

Re: DGND3700v2 no local LAN access from wifi
- no arp responses to queries
- i can only ping the router himself
- no access to my LAN
If i reboot the router, the wifi connection "works" again.
I said "works" because with the wifi connection working, i have a lot of lost packets (between 2 and 5% testing with "ping") even if the router is just near my laptop (about 1 meter). It's ok to go to Internet and access some files on my network but it's not normal i think.
With the same laptop on another wifi connection (airport or Dlink DSL2740b), i have no lost packet.
This router seems to have serious wifi problems...

Re: DGND3700v2 no local LAN access from wifi
How do you tell if you have v1 or v2? I can't see anything on the modem.
explicitly said the forum V# question many times
ONLY V2 and up will have V# shows after the model# (ex DNGD3700V2)
otherwise you will have V1.
Does anyone think I have a chance at getting my money back from Netgear?
Return the unit from vendor your purchase or if let go the return vendor policy to not abel to return then you waited too longs
Netgear will not refund the money but only to RMA exchange the unit.
