I am attempting to 'extend' a 192.168.1.0\24 network with an experimental network 192.168.10.0\24 using a 1941W router.
I have configured 1941W to distribute a 192.168.10.0\24 network, with WLAN access via the integrated wlan-ap 0 and using
This works fine initially however after a few minutes, clients dissociate from the AP - then reconnect. When this happens, they seem to be unable to 'regain' their lease (Wireshark shows continual DCHP Discover packets with no reply), and the IP - however the lease is still shown in the DHCP bindings. Renewing the DHCP lease at the client end has no effect. The intermittent nature of this implies its something to do with the wireless but I'm not really sure.
The only way I've found to fix this is to reload the AP, but as yet haven't found a change that makes a meaningful difference. Any guidance or help would be much appreciated!
This is shown in the dot11 association
and DHCP bindings below:
Where we can see that the 9801.a7ad.ea73 client both has a lease and association...but no IP address.
Please find my configs for the 1941W and wlan-ap0 below
