Hi,

I’m using a TD-W9960 router/modem in bridge mode with my OpenWRT box.

Occasionally, after a long disconnection, my OpenWRT box fails to obtain an IP address from my ISP (via PPPoE). However, when I switch the TP-Link device back to router mode, it successfully obtains an IP within a few seconds to two minutes. This makes me suspect that some PPP options or parameters might be incorrectly configured on the OpenWRT side.
 

Could you please provide the PPP options/parameters used by the TP-Link device?

Thank you!
