Forgive me -- I know these forums are meant for US products, but I'm at the end of my rope and don't know what else to do.
I received a D-Link DSL G256DG from my ISP here in Israel. I can't find this model or any manuals or help with it on Google, so I'm guessing it's some kind of project between my ISP and D-Link. It's a DSL modem / AC router and was required by the ISP to enable higher DSL speeds. My house is constructed of reinforced concrete, so in order to cover the whole place, I have two or three additional routers deployed where needed. In the past, I had a plain old DSL modem feeding Internet access to an ASUS RTN16 which handled DHCP, and then the other routers (a Netgear and an old D-Link) had DHCP disabled and just served as access points (or occasionally I had them configured to do DHCP on their own reserved section of IP addresses). Once I replaced the plain old modem with the D-Link DSL G256DG modem / router, the other routers on the system could "see" the DSL G256DG, but when I tried accessing the Internet via those other routers, I would get a momentarily normal-speed response, but then after just a few seconds, the speed would dial immediately down to basically zero and I couldn't get any usable connectivity through those secondary routers. Connectivity remains totally normal when connecting directly (wired or wirelessly) to the DSL G256DG. Any help would be much appreciated!
Thanks
