Hey all. I'm running shibby's Tomato (1.28.0000 MIPSR2-121 K26AC USB AIO-64K) on my Asus RT-AC66U. I had my ISP upgrade my line to a 1G (1000M) connection. But, when they set the line to 1G, the connection goes offline and won't come back online. The Asus RT-AC66U is capable of 1G speeds, and I've swapped out all my ethernet cables with new (tested) Cat5e cables that can sustain 1G speeds. Right now, the (working) WAN connection is showing 100M FULL (via Status > Overview > Ethernet Port State) and my single LAN port is showing 1000M FULL (which is connected to my 1G switch stack). But, if I go to Advanced > Miscellaneous > WAN Port Speed the drop down menu only lists AUTO and port speeds up to 100M FULL (1000M FULL isn't listed). Is this drop down list only showing "available" selections? What I mean is, since the WAN port is only reporting a 100M FULL port state (because my ISP has the connection set to 100M on their end), is that why there's now 1000M available in the drop down? Or, should 1000M be available? I have a really good feeling this is an issue with my ISP (and not my hardware), but just wanted to get other people's opinion. The reason I say I have a good feeling it's an issue on their end is, we also ran a test connecting direct to one of my machines (ISP's ethernet direct into the 1G ethernet port on my computer), and same thing happened—port link speed would be 100M initially (which is correct, because the ISP has the connection set to 100M), but as soon as they set it to 1G (1000M), the port would go offline. But, I know the port on that computer is capable of 1G (as I have it attached to my switch stack right now and the link speed is 1G). As well, I checked another router I have (an ASUS RT-N16) and it's also capable of 1G on the WAN. But, it's only connected to a 100M line—and same thing—Advanced > Miscellaneous > WAN Port Speed the drop down menu only lists AUTO and port speeds up to 100M FULL (1000M FULL isn't listed). Thus, I'm assuming Tomato limits what's in that drop down to "available" speeds. FYI—both routers, via Advanced > Miscellaneous > WAN Port Speed are set to AUTO (so, they *should* auto-negotiate at 1G, when available). Anyway, just wanted to see what other's opinions are here? Thanks, Kristin.
