RBR750 unable to assign IP addresses after reboot
Hi, every time I reboot or unplug my router to move it, all my devices will disconnect and will have an "unable to assign IP addresses" error. I have 48 devices and all of them will not connect. I wo...
firmware V4.6.8.2 for the router.
I am using a CM600 modem with optimum.
I'm not sure about the distance, but my backhaul is good.
Satellite 1 - 2 is V4.6.8.2
Satellite 3 is V4.6.5.14, it says there's no new firmware for this one.
What browser are you using? Try a different browser?
What are you seeing when you trying to set an IP address reservation?
Has a factory reset and setup from scratch been performed since last FW update?
I tried, chrome edge and safari. I don't think it's browser related since I the devices can't connect to the wifi. It says invalid IP address when I try to connect to it.
I'll try the firmware updates.
Factory resets seems to be the only way to fix it. A simple reset doesn't fix it. Some devices will still have trouble connecting but it resolves itself after about a day later.
I just tried manual update and it says firmware upgrade failed. I wasn't able to see the option to upgrade the router either.
Edit, after the reboot from the update, all my ip addresses are invalid again. I am replying using my mobile data.
If your on v.2 I recommend not downgrading FW.
I would do a factory reset and setup from scratch. I would also change the IP address pool size to .100 to .200. Gives you plenty of room for IP reservations and gives you room for static IP addressed devices on either side of this pool.
