I got a fiber connection the other day and thus I have a new "modem" which I want to use with my old trustworthy WNDR3700 (v1 I think if I remember correctly (running DD-WRT v24-sp2 (07/24/13) std - build 22118)).
Anyhow, I've had no luck getting a DHCP IP address from my ISP. If I connect a standalone computer everything is fine. I've been testing back and forth and finally I put an old 100Mbit switch in between the WAN port of the WNDR3700 and the "modem" and suddenly everything is fine and I get an IP address etc., no problem!
Problem is, that I don't get more than 100Mbit now since they aren't communicating on Gbit and I need to have an extra switch running as a "filter" which is of course not optimal.
So, anybody seen this kind of problem and have any ideas or something to try?
Berkutta; interesting thought, I will try a Gigabit switch and see what happens. As far as the cable is concerned, yes, I've switched cable. I've also used a tester on the cable and through the patch panel I use and it comes up as a good 8-wire cable.
