EX6200 drops 2.4GHZ connection every day or so

Thanks for your reply Andy,

After my post I read the fix for the problem described in "EX6200 - Stops assigning IP Addresses".
That topic made me try to look for potential problems in my router.

The most significant step I took was: reconfiguring the router so that the EX7000 is having a static ip address.

The main reason I didn't try any of this before, was that there was only one device of all that connected to the EX7000 was experiencing this problem. So I suppose the DHCP settings of the router were the source of my problem.

If the problem comes back, I'll come back. But the device is working brilliantly the last three days in a row. My internet speed is much faster than before (all devices are connected via wifi), also for the 2.4GHZ network!
