I have cable modem service from Charter communications. My issue has to do with the way Charter handles DHCP between the Peplink router and the cable modem. My issue is NOT with the Peplink 20 in any way, but I am hoping for a workaround…
Charter resets the cable modem frequently. Sometimes (four times so far this week) the router is unable to get an IP address from the cable modem after a reset. My old Linksys router running Tomato had the same problem, but not as often (once or twice a month).
If I hook up my laptop, I get an IP address from the cable modem instantly. I researched it, and it appears that Windows sets the DHCP Broadcast flag by default, but most routers do not.
Is there any way that I can set the Peplink to enable this flag?
Apparently, at a command line it would be “dhcpcd -B eth0”
According to the OpenWRT documentation this will “Enable the broadcast flag in DHCP requests, required for certain ISPs, e.g. Charter with DOCSIS 3”
Thank you for your time…
P.S. the Peplink 20 is running perfectly and the DSL line is keeping me up and running!! Thanks again!
