1482680 2021-12-07 21:09:00 Hi guys

It's been a long time since I was here but hoping the community is as alive as ever.

I have setup an old Orcon Netcomm N4FV Router to extend my wired and wireless network to my office which is in a separate building from my house.

Everything is working fine except if I use the same SSID as the house/main Wifi (Huawei 4G Router B618 on 2Degrees rural broadband) then my Android phone will not obtain an IP address when connecting via the NF4V if it has previously connected to the Huawei. I have tried a fixed IP address on the android handset. This fixes the issue of obtaining an IP address and I connect to the network but then I am not able to connect through to the internet.

I suspect it is some sort of security measure being applied at the Huawei router based on the device's MAC address but I am not sure.

I also have a solar inverter that connects to my wifi. It seems to switch between the two access points based on the strongest signal at the time with no issue. I know this because sometimes it appears as a wireless device in the Huawei's device list and sometimes as a wired device when connected via the NF4V. So it obviously is getting an IP address regardless of which wireless AP it connects to.

As a workaround, I have created a second SSID on the NF4V and now my android device switches to that after it cannot get an IP address and works fine. I could therefore just have different SSIDs and there would be no issue. But I would like the same SSID so I only have to setup one wifi network on each of my family's android devices, and when guests come to stay, etc.

Any ideas?

1482681 2021-12-07 22:20:00 Does the netcomm router still have DHCP turned on for clents? it shouldn't, let the primary do it. psycik (12851)
1482682 2021-12-07 22:45:00 using old routers for wifi access points often ends in tears . Ive seen this setup take down a network on a few occasions (DHCP conflicts)
Better to buy a real wifi access point.

Anyway, use a different SSID on that router . That should solve your issue , for a few reasons
assuming its all setup correctly :)

Sorry I should have said.

Yes, DHCP is being handled by the Huawei / primary.

Both are on the same subnet. i.e. Primary: 192.168.x.1, Secondary 192.168.x.2. Secondary points to primary IP as gateway. DHCP is turned off on secondary.

They are connected together by an ethernet cable LAN to LAN ports.

IGMP snooping is enabled on the secondary.
MAC filtering is off on both
LAN side firewall is off on secondary
Wifi mode is Access Point (not bridge) on secondary

1482684 2021-12-07 23:14:00 Yep, I might get to that point, but I thought it worth a shot first off using what I have and posting a quick trouble-shooting message on this forum. echothreezero (6612)
1482685 2021-12-08 00:49:00 Random comment, do you have an unused laptop? I use that to bridge the wifi where I live so I can access the internet from my room the_bogan (9949)
