Hi,
I have a netgear WNDR3700 running Gargoyle 1.5.8.

One of the lan ports is connected to a gigabit hub. However, the router is not able to establish the link to the hub.

The port light just blinks green at a fixed interval (about 2 seconds) when the cable is connected.

The switch works fine with stock netgear firmware.

On debugging this a bit more:

- The hub is connected to router through some in-house cabling (which is very long).
- If I connect the hub directly to the router via a short cable, it works fine.
- I connected the laptop to the same long cable as the hub - and the laptop was able to connect, but at 100mbps instead of 1000mbps.

Router -> Hub (short cable) -> Laptop:

Code: Select all

en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=2b<RXCSUM,TXCSUM,VLAN_HWTAGGING,TSO4>
	ether 3c:07:54:42:5a:aa 
	inet6 fe80::3e07:54ff:fe42:5aaa%en0 prefixlen 64 scopeid 0x4 
	inet 192.168.1.214 netmask 0xffffff00 broadcast 192.168.1.255
	media: autoselect (1000baseT <full-duplex,flow-control>)
	status: active

Router -> Laptop (long cable):

Code: Select all

en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=2b<RXCSUM,TXCSUM,VLAN_HWTAGGING,TSO4>
	ether 3c:07:54:42:5a:aa 
	inet6 fe80::3e07:54ff:fe42:5aaa%en0 prefixlen 64 scopeid 0x4 
	inet 192.168.1.214 netmask 0xffffff00 broadcast 192.168.1.255
	media: autoselect (100baseTX <full-duplex,flow-control>)
	status: active

Basically, it seems that the router is not able to drop the connection speed to 100mbps when it notices a bad ethernet connection.

Is there a way to manually tell the router to do this?
