DD-WRT on the R7000P reports that the WDS connection exists, with good signal strength, but once I unplug the cable that joins them, no pings will go through.
I can see on the NL1901ACV that it's bridge interface includes its WDS interface, whereas on the R7000P DD-WRT hasn't done that. I tried manually adding the WDS interface to the bridge on the R7000P, but it had no effect, so I assume I was on the wrong path there.
So, what should I be checking next? I'm a little hamstrung by the firmware on the NL1901ACV, but it does give access to a handful of Linux networking command-line tools.
First of all, WDS only works between routers that have the same chip manufacturer (Atheros and Atheros or Broadcom and Broadcom). Don't try to go Atheros to Broadcom or vice-versa.
Turn off wireless encryption for testing purposes on both.
Also, dd-wrt will show the WDS AP connected in the Status - Wireless menu, bottom of the page. If the Signal level is at 0%, it is not connected.
PS: I have only ever done Atheros to Atheros in recent years. I know there was issues with WDS on Broadcom a while back. I am not sure if it was ever fixed. Netgear R7000P is Broadcom based. Wikidevi is a good source for this. _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware? I suggest reading it all.
Some dd-wrt wiki pages are up to date, others are not. PM me if you find an old one, I am trying to update them.
