Question

Hi

I recently upgrade to fw version 6.05.1 but I am detecting to much DHCP lease request. (clear upgrade. not keep old cfg)

I have a simple configuration with 3G/4G SIM as main WAN connection (no backup) , static leases table and no extra complex configuration. (just reboot all Monday at 4:00 and simple ping reboot)

I saw lot of DHCP entries.  Is it normal?  Could it overflow some kind of buffer and force a Reset or lock RUT webpage?

last weekend I saw multiple lease request from same device and on Overview screen does not update 3G mobile Status. all information was as N/A or simillar, BUT 3G connection was very slow but working.  Need to power OFF/ON to return "normal" situation, but DHCP leases are here again.

today latest events

Hi,

It's normal if the client devices are moving around (both physically and in between other access points). It shouldn't be an issue with the router, because the clients are the ones requesting leases. And no, it shouldn't cause any problems to the RUT.

ThankU very much.

Devices are not moving,     not more than 10-15m around RUT., and signal is great.

Could be that they are entering to low power, or something like that, and when wake up they request DHCP again?

RUT is alone and is the main router for my home. Devices can not switch to another "radio/wifi extender".

Anyway, thankU for your answer.

I suggest you look up the specifications of individual devices that you use to find out whether they have such a feature or not. :)
