DHCP issue with ORBI RBK50 configured in AP mode
I recently replaced my old Apple Airport Extreme by a brand new Orbi RBK50. I'm running the last FW 2.2.1.210.
The Orbi (RBR) is configured in AP mode and one satelite (RBS) is configured in wirele...

I guess I'm right if I say turning Orbi into AP mode disable its DHCP feature?
........
Yes, once Orbi is on AP Mode the DHCP functionality should be diasabled.

I discovered some strange behaviour yesterday evening. One of my wireless device sucessfuly connected to the network and it apparently received an IP from an already connected wired device (when I came to my wired device I saw the error "An other device use your IP address".

Do you have any extenders/repeaters or Wifi-LAN converters? Those devices have built-in DHCP servers and I noticed that sometimes they can interfere with the main DHCP server.
Please get the following information that will give us information about the configuration in Orbi:
- From a browser go to the router's debug page (http://192.168.1.1/debug.htm). Use your router's IP address
- Enter admin as user name and your router’s management password
- Tick "Enable Telnet" option
- Use Telnet to connect to your Router telnet 192.168.1.1 (use your router's IP address) and enter admin and the same password as above
- Enter the following commands, and copy the output printout:
-
config get lan_dhcp
-
config get lan_proto
-
config get ap_dhcp_ipaddr
-
config get ap_dhcp_gateway
- config get ap_dhcp_netmask
- config get bridge_dhcp_ipaddr
-
config get bridge_dhcp_gateway
-
config get wan_proto
-
config get wan_dhcp_gateway
-
config get wan_dhcp_server
-
config get config get bridge_dhcp_netmask
-
Nope no extenders, repeaters or anything else ...
here is the debug log

For those wireless moblle devices such as iPhone or iPad who can get connected I noticed very unstable behavior (good throughput for 5 minutes to very low throughput without moving, connection drop after some minutes or hours). Sometime when trying to reconnect I got errors such as 'incorrect WIFI password'. Waiting 5 minutes and reconnecting solved this issue without retyping the password but it reapears from time to time.
I made the count, I have 26 devices to connect (IP camera, Sonos, Hue bridge, Amazon echo and multiple dots, Apple devices, ...
The most frequent issues occurs with Apple devices (2 x iPhone, 2 x iPad).
Do you run the same last firmware?
Do you have some Apple device connected to your Orbi?
Not convinced by Orbi so far to be honest ...

Data should be ok. It says that Orbi is connected to your router at 192.168.0.1 and your DHCP server is located on 192.168.0.25. We can try to set the DHCP address to same as the gateway address (192.168.0.1) if your router has already the DHCP address defined. Let's keep this as last resort.

......I think this is only symptoms of not having a working DHCP in your network, once the issue of DHCP is sorted out I think these issues will be gone..

.....Sonos! Do you have any wired Sonos? I had so many issues when I had my mesh speakers wired to Orbi. Please test to disconnect the wired devices and see if anything will improve.

We are an Apple house so I have all types of Apple devices, Macbooks, iMac, iPhones, iPads, Apple TV. I also have wired Time Capsule that I use for backups. All are working perfectly fine with Orbi.
I'm suspecting the Sonos affecting your network. Let's exclude this first.
Hi there,
I think i finally found the issue. Quite unbelievable...
After some investigations, It appeared the DHCP server supplied by my ISP provider delivered only ... 26 IP addresses.
Since I just reached this limit by adding the RBR50 (one base + one satellite), I never experimeted such an issue.
I called the representative and asked him for an hardware replacement. They proceeded within half a day and hopefuly the dhcp issue disapeared.
Regarding SONOS I have 4 play 1 and 1 connect. They are not using wireless but sonosnet. Of course the connect device is wired to my network but I have not encountered any issue so far. Let's see in the coming days.
I'm not impressed by the trhoughput comparing to my old airport but it works and it's ok.
Let's see the stability for one or two weeks now...
In the meantime I will try to enable fast roaming and implicit beamforming te see if it helps somewhere...
I'd like to thank you very much for your help. It was really appreciated!
Cheers,
PS: long live to Apple, since I'm also an Apple house... ;-)
Glad that you got the main issue sorted out. Let's hope things will be stable now and you will start fully enjoying the lovely Orbi wifi system! :)
