    DHCP leases and connected clients

    So I'm currently troubleshooting my ISP's proprietary router (which I believe is built around a Cisco ME 4600, I found that the CLI commands are similar) due to a problem with the 2.4GHz signal, which stops responding after a few days. After trying everything (different channels, SSIDs etc) I'm...
