Not getting IP address from ISP

[abuckxr]

I have a WNDR3700 v1 router.

I flashed to the latest version of Gargoyle 1.6.2 last night. Everything seemed to go smoothly. I noticed when I logged in Gargoyle for the first time that I had no connection information. I cannot seem to get DHCP information from my ISP at all.

A few notes:
1. The router is connected exactly as it was before I flashed the firmware from the stock firmware. No cables have changed, no network equipment moved, etc...
2. I do not have a cable modem. I have fiber, so I just have an ethernet cable that comes into the house. (I mention because there is no modem between me and the ISP).

Configuration Notes:
1. I am using Gateway (the default)
2. Connect Via" is set to "DHCP (Wired)" (again, the default)
(this is also how my netgear stock firmware was configured)
3. Current Lease Expires is blank because there is no connection
4. I have tried checking the "Use Custom MAC Address". (I have not tried setting a different MAC address....just using the actual MAC address of the router)
5. I have tried setting to STATIC settings to match what I had configured in the Netgear stock settings. I have also verified that when I connect my PC direct to the internet that these are the settings being delivered by my ISP. No luck.

I've rebooted the router multiple times.

I've run out of things to try. It's like the WAN port is dead on the router once Gargoyle has been installed. This is just weird.

I'm thinking of reflashing back to the factory firmware. Kids have home work to do tonight, our IP phones don't work, the smartthings hub doesn't work without an internet connection, etc...

Anything obvious that I'm missing? Any known bugs that I should be aware of? Any suggestions would be appreciated.

Thanks

P.S. I really HATE the stock firmware on this router and really do not want to go back to the factory firmware. I know how to do that if I can't get Gargoyle working, but I don't want to do it.

Is it possible to flash from Gargoyle to DD-WRT using their "webflash" .BIN file? If so, maybe I'd try that and see if this problem exists only on the Gargoyle firmware.

I tried flashing to DD-WRT, but it didn't work. Not sure why, but I didn't have the patience to try and figure it out.

I restored back to factory Netgear firmware and everything works just fine now. The router gets DHCP from the ISP no problem.

This is too strange. This has to be a bug.

In a few days, I'm going to try and flash Gargoyle again and see if the same problem persists. I'm betting it will.

What country? What ISP?
Some ISPs in some countries use VLAN Tagging for fiber connections.
Also confirm the the WANs Mac address when stock firmware is installed is the same as the WAN Mac address used with Gargoyle installed.
