Hello,

I've installed the latest X-Wrt image on my Netgear WGT634U. After changing the configuration of the VLAN (deleting VLAN1) I can't reach the router anymore. It does not seem to be dead. I can still connect to the WLAN ESSID of which the router the AP is. It also still works fine as a switch (using two of the LAN ports). I just can't reach the router itself.
Is there any way to resest the machine to some kind of working state? I don't care about loss of config or whatever... Unfortunatly I don't have something like a serial cable at hand.

Thanks!

Florian

Really nobody has a hint on that for me?
Is there a chance I get into the device when it boots? Or is a serial cable the only possibility?

Did you enable boot_wait? If yes, then you can upload new firmware (or the same you are using) via TFTP. This will overwrite all configuration parameters.
http://wiki.openwrt.org/OpenWrtDocs/Installing/TFTP.

The WGT634U is different...

I thought when you flash a WGT634U with an OpenWRT firmware, you can enable boot wait.

I've found no information regarding boot wait and the WGT634U. Although IIRC I have read somewhere that it is not supported. Anyway I've flashed from the Netgear webinterface with the X-Wrt images and changed nothing like boot wait.

The boot loader on the WGT634U does not support boot_wait.

You need a serial cable (with a level converter), see the hardware page

I personally went with a 2nd OpenWRT supported router (Linksys WRTSL54GS) since I already had it.  I connected 1/8th inch stereo jacks on both serial ports of each router.  Then I just connect a 1/8" cable up between the 2 units, and it works great.

Access by serial console is best, especially if some configuration files got corrupted. http://wiki.openwrt.org/OpenWrtDocs/Har … ar/WGT634U helps a lot with that; any mobile-phone usb-adapter will do. You may consider getting one so you're free to manipulate :-).

Well, that's true!

A serial-usb adapter like that on * will do it too? Of course I still need to do the wiring (buy a serial cable and cut through to get to the wires is my plan)

Be forewarned that the particular adapter you've noted is not sufficient to do as you'd like.  As I had mentioned you need a level converter because the voltages on the serial lines in the router are not high enough.   The cell-phone adapter deals with this by default, the adapter you link to does not.

Ok, that's good to know.
Is any mobile phone cable fine? Is there a particular sign I can use to see if a cable is suitable?

Go to the wgt634u hardware page linked in a couple of the above posts and check out the explanation of what to do for a serial console.  It'll answer all your questions.

I've read the WGT hardware pages a couple of times. Still it's not very easy to see what you need when you're not experienced with micro controllers and all those stuff.

Here's another page that might help:  Serial adapters
