DHCP pass through issue ex7500
Hi, I’ve got a ex7500 extender Everything works fine and after a couple of days devices connect to my ex7500 but don’t get dhcp address . I see them connected but with no ip. Everything returns to ...
What actual firmware is on the orbi and on the EX7500?
Did you setup the ex7500 using wps?
Is the ex7500 connected to a satellite or to the router?
What modem/gateway do you have?
How far from the router is the satellites and the ex7500?
Have you noticed the configuration of your orbi changing when this happens? (changing from daisy chain to a star configuration)
Ex fw 1.0.0.72
Orbi fw 2.6.2.104
ex7500 manualy Connected directly to the orbi router (lan 10.0.0.1) (wan 192.168.1.134)
Providers modem in router mode - Upc compal (192.168.0.1) 400/40 mbps
orbi satellite 1st floor, orbi router 2 floor, ex7500 3 floor.Daisy chain is disabled.
satalite and ex have a good link to the router.
the ceiling between the orbi and its satalite is concrete. The ex doesn't connect the satalite, it connects directly to the router.
same happens when the orbi satalite is switched off.
The ex works for a couple of days and devices stop getting dhcp.when I take them downstairs they connect to the orbi and work fine.
after restarting the ex, devices start to work normally

---Issues with double nat? cascading routers isn't a ideal plan.

---Does it work with daisy chain enabled? If the cement wall is between router and the satellite, it means the cement is also between the EX and the router. Cement is one of the best blockers of wifi.
same happens when the orbi satalite is switched off.
The ex works for a couple of days and devices stop getting dhcp.when I take them downstairs they connect to the orbi and work fine.---so, If the cement floor/wall isn't between them, there isn't any issues? Seems to indicate a poor signal with the cement in between and eventually dropping signal.

- I switched off the Orbi satellite (for testing).
Providers router switched to modem mode.
The ex has a stable link (on the debug page status shows green all time, speed 650 Mbps -704Mbps ).
Devices linked to the ex stop getting DHCP after a day or so.
The same devices linked to the router get IP immediately.
When I change to static IP, they work fine linked through the ex.
Download speed test show ca. 350 Mbps, so the link seams to be stable.
I go back to DHCP and when linked to the ex, stop working. No IP in ipconfig.
What’s wrong? Why does the ex blok the DHCP?
How can I check if it’s the discover/offer or request being blocked?try this.
put your gateway back in router mode and disable its wifi.
Then put the orbi in access point mode.
then connect the extender to it.
Maybe the gateway's passthrough/modem only mode is sketchy
