Hi,
Within the last few weeks I've started having wireless connected devices drop off from our router, but wired devices have no issues.
I have tried running in both 5GHz only and 2.4GHz only, and changing different channels to no avail.
I've had the same number of wireless devices connected to my home network for around 6-8 months, so not sure what could have changed recently.
One also interesting thing is our DHCP setup stops working and all wirelss devices are assigned a 169 IP address, as if they don't see any reservation at all.
Is this the sign of a dying router?
