    DHCP leases and connected clients

    Sometimes I check how many leases DHCP has issued using this command. cat /var/lib/misc/dnsmasq.leases | wc -l That doesn't really tell me if those clients are connected or not. So, to check how many connected clients I have, I try this: arp -a | awk '$4!="<incomplete>"' | wc -l The thing is...

    Apple devices can't access Internet if IPs are DHCP-assigned

    DIAGRAM UPDATED Apple devices cannot connect to an ASUS RT-AC66U configured as a repeater when set to use DHCP-assigned IP addresses - they can only connect when using statically-defined IP address settings (IP, mask, router IP & DNS). Why is this not working with DHCP-assigned IPs for Apple...

    DHCP hostname cannot be queried outside of LAN in dual-router home network setup?

    Hello everyone, I am having trouble achieving my goal of a dual-router setup in my home network, where I'm able to resolve the IP address of a host while connected to the other router.

    RT-AC68U 386.2_6 - WAN_Connection: ISP's DHCP did not function properly with TekSavvy / Cogeco cable

    There are many threads about this issue already on snb, for example this one. I am only creating this new thread to indicate that specifically with Cogeco cable (resold through TekSavvy, though I doubt that matters) there is no current solution to the issue. If anyone is not familiar with this...

    DHCP reservations limit

    Hi all, Just migrated to Merlin from stock; love it as usual! Having a RT-AX86U it says on the DHCP page "RT-AX86U supports up to 253 IP addresses for your local network." I can only reserve 64 addresses? Did I misunderstand the 253 IP addresses statement? Or is this a misbehaviour from my...
