Hi. My rt-n16 is bricked. I was able to connect trough serial but when I plug in the ethernet cable nothing happens.
My computer asks to connect the cable and no link is blinking on router.
Is there a way to check if ethernet part of router is working at all?
One of the chips on the board - CAT7581CA is heating is hell. After reviewing its datasheet I understand it converts the voltage. Maybe it's broken and doesn't provide the power for ethernet port?
I think if I'm not the only one with this dead ethernet ports it worth adding the instruction on how to flash over the serial itself...
Looks good. Level shifting ttl. However a CA-42 is less money and saves you from having to mess with power (vcc+) which can fry things if you hook it up wrong. _________________ I fix "shortcuts". If you don't have time to read thoroughly, I don't have time to re-type what you missed.

I have a wrt610 v2 with the serial in the WAN port, so I will also have to make a plug like Eko's. Will I be able to solder to those pins on the CA-42?

The serial will also be on the motherboard of the router, and it is safer to access the one on the motherboard. But yes, you can use the WAN port as well, if you can get the leads lined up. It is very difficult, imho. You only need three...rx, tx, and grd with the ca-42 so you don't have to worry about frying your serial port as easily (regardless of whether you use the mobo or the wan port). _________________ I fix "shortcuts".

Thanks Peabody All the PCs I have are running Win7. From what I have been reading, there seems to be issues? Any suggestions to help a noob would be greatly appreciated

Can't help you as I don't use Win7. Best advice is to read all of this thread. Read the wiki serial recovery article. Get a Win XP computer if you have problems with win7. _________________ I fix "shortcuts". If you don't have time to read thoroughly, I don't have time to re-type what you missed.
I use two PL-2303 based cables without trouble on Windows 7 x64, if you need drivers they can be found here _________________ Netgear R7800, 46885 (05/06/2021)

Just my 2 cents...
I am using a generic CA-42 cable with Windows 7 64 bit and it works good. This particular cable had 5 wires so I had to supply the 3volts with 2 AA batteries since the adapter isn't powered from the USB port. See the bottom 2 posts on the first page for more info:

This also allows me to set up the Putty or Hyper-terminal window before powering on the router, allowing me to easily see all the boot info, as well as making it easier to interrupt with CTRL-C.
As far as drivers go, I let Windows search online and it installed the Nokia CA-42 drivers from Windows Update.

Mine had five wires, and I did not need to power the usb with batteries. If windows recognized it when it was plugged in, the adapter was powered. I just used the tx, rx and ground. Worked fine. _________________ I fix "shortcuts". If you don't have time to read thoroughly, I don't have time to re-type what you missed.
I've got one of these (link below) on hand from having to resurrect a Netgear router in the past and I'm wondering if it would work in place of getting a CA-42? I want to have something on hand just in case I ever need it to revive a E2000.

Yes it will work, I wouldn't recommend others to buy it but that is only because of the price, a CA-42 is $3-4. _________________ Kernel panic: Aiee, killing interrupt handler!
