Posted: Sat Aug 15, 2020 4:25 Post subject: Is this E900 router fully bricked - or is there some hope?
I have an old e900 which was running perfectly okay with dd-wrt version 42557 - configured as a repeater
When I saw no broadcast from this repeater today - I opened this in the GUI (via WiFi) and did a reboot using the reboot button on the Services>>Services page.
The router restarted - but still no WiFi.
Then I removed the power plug and put it back on.
Since then - the router is not booting up.
All the LEDs are lighting up - but with a very low light intensity. 30-30-30 reset is not workig (no change in LEDs when reset is kept pressed) Unable to ping the router even if I connect via ethernet cable.
Is this bricked?
At the time of removing the power plug, I noticed that the correct LEDs were glowing with normal brightness.
Though this is an old piece of hardware which has given it's due share of service over the years - I would like to attempt a recovery if this is possible. Can anyone help me - or guide me to where I can get some study material.
To eliminate that the power adapter is okay, I connected another adapter of the same specs. Same results - therefore I think the power adapter is okay and issue is with the router. _________________ PROFESSIONAL STUDENT my.Mistakes ∝ my.Learning ... provided I have the patience & persistence to learn
Should I try a serial recovery? (I mean is it still recoverable?)
Is this the correct adapter to be used for the E900?
The ad says:
The main chip CP2102, generates virtual serial port after installing the driver, Taking power, USB and elicit interface includes 3.3 V (< 40 ma), 5 V, GND, TX and RX, signal feet is 3.3 V, is logical

All LEDs glow dimly as soon as the device is switched on - and there is no response after that.
Reset does not respond.
30-30-30 does not respond.
No Ping (else at least I could try tftp)
In fact, when connected to my laptop via ethernet, the laptop does not even recognize that something is connected.
(Edit/Added image of what happens the moment I switch thr router on. Absolutely nothing seems to respond after that)
I am in India - and my choices are pretty much limited to these...
DTECH Electronics and DSD TECH are China so if you search model numbers and/or description you should be able to find them on other sites, distributors for your region.
You may want to test the external power supply with a multimeter.
Another possibility is failing components inside the router such as capacitors.
I had already ordered the above adapter (the picture I posted) because that gets delivered by Monday and costs 1/5th. If that doesn't work, I'll look at the one you suggested.
Capacitor may be an issue because I noticed a tiny spark twice - while inserting the jack into the router's power socket. A capacitor holding charge is one of the probable reasons for such sparks. Have to check this angle too. _________________ PROFESSIONAL STUDENT my.Mistakes ∝ my.Learning ... provided I have the patience & persistence to learn
