You don't hook up vcc. The guide says hook up ground, tx and rx.
Like I've said twice now, if after connecting the rx and tx wires together that are coming off of the adapter and nothing shows in putty after typing, then you have a bad adapter or putty is setup wrong. _________________ I am far from a guru, I'm barely a novice.

This is my putty screen, https://ibb.co/gbJCb7 , it generates one of those blocks every time I power the router up. Ctrl C does not work.
Sorry I decided to continue with this post. thank you for helping.
I believe the bootloader is gone. Do you think it would be possible to use the jtag to flash a new boot loader on? do you know where I could get the file
Did you checked the power supply (as Murrkf mentioned) ? ; Is the output voltage correct?... if is possible try with other power supply... i've seen that led behavior before on other routers, indicating some kind of power failure.
Tried multiple power supplies, all of them had good voltages. I think it's a hardware defect, I've had the router for 4 years now and every 2 months I had to reflash the firmware (people said i was doing things wrong if it kept breaking like that ). Anyways this is the worst state it's been in.
Would some kind soul please point me to the cfe.bin file, I've come across this link. https://www.dd-wrt.com/phpBB2/viewtopic.php?p=678195 , I'm not sure where the cfe starts and where it finishes on the first post
Unless someone has a cfe.bin for you to use you won’t be able to flash it.
It’s an E900. What country are you in. I have an e1200v2 you can have for $5 or an e3000 for $10. _________________ I am far from a guru, I'm barely a novice.
Ah thank you for the offer of the Router's , but i'm ok (i'm from south africa ) . I just like trying to keep old things going
If I swap the TX and Rx, then i'll have Tx to Tx and Rx to Rx (i'll try when i'm home, if I dont respond then it didnt work ).
I've tried without vcc connected and i've tried powering the board with only vcc. Haven't tried a combo of the two , but that sounds hazardous. All have the same result
You don’t use vcc. You only use ground, to and rx.
The router gets powered by its own power supply.
Touch your tx and rx together and see if your keystrokes are echoed in putty. _________________ I am far from a guru, I'm barely a novice.
I did some tinkering the other day( just used a different machine to communicate with it). I had some little progress, I got it to 'communicate' https://pasteboard.co/HoDMSVG.jpg . Do you think if I somehow get the cfe.bin that this router will be recoverable?
Also the LED lights are dimmed on all the time. It makes me think it is a power supply issue, however I have tried multiple power supplies. I've also checked the voltages throughout the board, all correct. Even the winbond chip is correct at 2.64v (seeming as this is powered by the Broadcom chip, I think ) . I believe it's just a corrupt boot loader ?
To flash the cfe, you’d have to use jtag, which means buying equipment that would cost more than the router. _________________ I am far from a guru, I'm barely a novice.

hi,
i'm facing the same problem. e900 all lights on, and can't ping. trying to connect with serial adapter but no outpt in serial termial.
could you share how do you fix it?
). Anyways this is the worst state it's been in.
