XAVN2001 and subnet mask
Hello!
I recentely bought a XAVN2001 wireless extender powerlin adapter. The XAVN2001 is connected to my ISP router through another powerline adapter (XAV5501).
I use subnetting in my home network to separate my home and guests networks. The ISP router is configured as follow:
Gateway IP for home subnet: 192.168.1.1
Gateway IP for guest subnet: 192.168.1.129
Subnet mask: 255.255.255.128
Home subnet: 192.168.1.0
Guest subnet: 192.168.1.128
In the basic settings page of the XAV2001 webinterface I tried to assign manually this configuration to specifically make it part of the home subnet.
IP: 192.168.1.3
subnetmask: 255.255.255.128
Default gateway: 192.168.1.1
DNS: 192.168.1.1
However, when I try to apply these settings, the webinterface refuse to validate these setting with the following error message: "ip address and dhcp server ending ip address must be in the same subnet"
There is actually no DHCP server settings in that webinterface that I could change and, to my knowledge the settings that I'm trying to apply are valid, I have another linksys router that works flawlessly with those settings. What's wrong? It should be legit settings, no? It looks as a webinterface coding bug
to me...
If I let the settings to automatic, it works good but the subnetmask is 255.255.255.0
I don't know if and how it could affect the separation between my home and guest network, as I have specific firewall rules that don't allow communication between these two subnets in my ISP router.
Any input would be appreciated, thanks.

- btw, I have the latest firmware (v0.2.1.6CE).
- most netgear are design to work with simple Class C subnet 255.255.255.0 so it is possible that 2 subnetting may not work like you are trying
- Thanks for the answer, but why put settings such as subnet mask, if they can't be assigned correctly?
- My suggestion is to ask support on this. I have seen any subnet thread like this on Poweline device
Use my.netgear.com portal to cintact support - powerline adapters including XAVN2001, behave like a L2 bridge, they will not do any L3 discrimination.
Your guest subnet in gateway is only for its wifi network, i dont think it is applicable to the LAN ports, then your powerline network which is connected to your LAN, is part of your home subnet, so any wireless cliente connected to XAVNB2001, will be part of the 192.168.1.0/25. The IP address 192.168.1.3 your are trying to set in XAVN2001 is for management only, so first it shouldn´t affect your separation; second the fix assignation should be set in the gateway as it is the DHCP server.
Did i help?
regards,
Robbbie - yeap thanks, it makes sense. But in the meantime I just suppressed the guest network..

Did you manage to resolve this using support ? Common when support only pastes from a knowledge-base.
I have found they are not very good.
English understanding is a bit flaky.
Technical knowledge is pretty low in terms of theory.
They answer within a day, even if it doesn't address your issue.- No, I didn't contact support, didn't take the time to do it. Most of the time when I contact support for electronics, I end up explaining things to the guy, even though I'm just an average PC enthusiast. lol.
