Hi,I recently bought a Tplink Archer C7 router.I have a t128 modem/router which is working fine with which I've set a working wifi hotspot.I was to make the t128 a modem only and to connect it into the tplink by a wired bridge.I connected them by a cable and disabled the dhcp on the tplink, then set the wifi hotspot on the tplink and disabled the t128 wifi.The new hotspot does work and I can connect it with my mobile phone and get internet.However, when I try to set an l2tp connection on the tplink it fails and the event log shows "dhcp unavaliable. recv no offer".I try to drop the firewalls and change all options that seemed related but it did not help....I need this connection to work, what can I do?Thanks!
