Hi,

I'm trying to configure a Buffalo WZR-HP-AG300H as a client bridge (routed) to an ASUS AC-RT68U main router. I followed all the instructions on several postings and the result is that the Buffalo router registers to ASUS properly using the 5GHz band.

I hardwired a notebook and a Raspberry PI3 into the Buffalo router. Both devices receive an IP address from the main router and can ping and access anything on the local network. Access to the Internet works for approx. 30 seconds after a Buffalo reboot and consistently fails afterwards (however still have access to the local network.)

The main router runs on Merlin 384.8; on the Buffalo I tried with exactly the same outcome the latest 2 Buffalo PRO firmwares (wzrhpag300h-pro-v24sp2-19154d.enc and wzrhpag300h-pro-r30356.enc) and now a current wzr-hp-ag300h-dd-wrt-webupgrade-MULTI.bin. I also tried removing the encryption on the 5GHZ band - the outcome was exactly the same - approx 30s of Internet access and failure afterwards.

Between the FW upgrades on the Buffalo I reset it to the factory defaults and did the 30-30-30 reboot. Here is the outcome of some tests I've done from the Raspberry (ASUS is 192.168.2.1, Buffalo - 192.168.2.225)

...so it looks like name resolution works.

I also have a PIX-LINK mini wifi router/extender and that one works just fine in bridge mode with the ASUS main router.

Any suggestions are highly appreciated.
