W70B network issues

[assistenza@voispeed.com]

Hi all,
we have network issues with many W70B.

Usually they have DHCP IP addresses. And they are all powered by their external power supply, so PoE is not used.

W70 is pretty configured and works for days/weeks.

Suddenly they lost the nework link (ETH led switches off). Sometimes a reset of the base helps, sometimes not and the base never comes up to the network, SO we have to change it.

The number of subscribed dect phones may change for customer to customer (i.e it happens on systems with 1 dect phone up to 4/5 phones).

We also tryed to set static IP address, and use the latest FW (W70B-146.85.0.40) but this doesn't help, so we suppose some issue on the ethernet chipset...

Does anyone have the same issues?

Thanks a lot
