Here is a brief overview of my setup, I was about to make a nice visio drawing of this but then it didn't work! :)

Motorola SB510B Cable Modem

| cat 5 (into WAN port on router)
|
Buffalo AirStation WHR-HP-G54 running DD-WRT Firmware: DD-WRT v24 RC-6 (01/02/08) std http://www.buffalotech.com/products/wireless/wireless-g-high-power/wireless-g-high-power-router-and-access-point-whr-hp-g54/

| cat 6 (from port 1 on router)

Netgear GS108 GigE switch http://www.netgear.com/Products/Switches/DesktopSwitches/GS108.aspx?detail=Specifications
|
| cat 6
|
Netgear GS105 GigE switch http://www.netgear.com/Products/Switches/DesktopSwitches/GS105.aspx?detail=Specifications


I have 2 PCs plugged into the 8 port with Cat 6

I have 1 PC, Xbox 260, Wii, and Popcorn Hour (Network Media Tank) into the 5 port with cat 5

I am going to order some cat 6 so that all my cabling is the same

My problem is the 8 port switch just blinks all its lights when I have the cable from the router AND the cabloe going to the other switch plugged in.

I suspected that the 8 port was bad a little while ago, but I'm not sure. I want to make sure this setup is possible before I RMA it or something.

Thanks

No reason it shouldn't be possible.

That's a good setup.

Sounds like a bad switch.

Should work fine.

I have a GS105 and GS108 as well that have run linked together for years now.

if your going from the uplink port to uplink port that is likely your problem.
Only use 1 of the uplink ports and connect the other end to a regular port.
You really should connect both switches to the router rather than each other.

Most semi recent switches don't have uplink ports (in the historical sense). They are mostly autosensing x0ver ports.

that is the problem right there.
If all the ports work to a nic then it is a negotiation problem between the switches.
Sometimes using a x-over cable will clear it also.
Sometimes using a different port helps
There seems to be a bigger issue with port 1 than the others on netgear switches.

Ah, gotcha.

Gigabit is auto negotiation. Should be no need for a crossover cable and it should work on any port.

I have those exact two switches, any port to any port works fine. The OP might try another cable just to be sure, but it should work with any cable.
