WNDR3800 recovery after power failure

[TonyB]

I had a power outage the other day and my WNDR3800 crapped out. I could see my SSIDs but could not longer connect to them. Normal reset to factory defaults did not work. After much screwing around I finally decided to load a new copy of firmware on it.
I downloaded latest copy of firmware and tftp'd to the router. Transfer was successful and Router rebooted as expected and came back on with all the lights. However I can't connect to it on ethernet at all. I have tried using a 192.168.1.x address manually as well as using DHCP (no address picked up). I tried connecting to the default SSIDs but the passwords do not work. I just get a timeout error.
No luck using routerlogin.com or .net either.
Any ideas?

After the firmware update did you hard reset the router again? Press and hold the reset pin hole for 30 seconds and release. Wait 30 seconds and power cycle the router. Now try.

sounds like unit may defective.

see router reset on my sig below for properly reset .

if still has an issues, I would contact support for RMA the unit.

also for tips, invest on APC backups (or similar) to all electronic devices. I have not failed any of my devices for 8 some years

Thanks for the advice. Tried all the reset options but not a one of them made a difference. Time for an RMA.

As for APC units, I am not really a fan. I started purchasing electronic devices in 1977 or so, and computers in 1986 and network hardware shortly afterwards. This is the first device I have had fail related to a power issue. And it will cost me about $100 to replace. Not bad with no APC. Now if I had sensitive data that was not backed up elsewhere that might make sense.
The problem with APC is the batteries. You have to replace them regularly or the UPS may not work when needed. I have worked as a network engineer for large companies for almost 20 years and they are slowly getting rid of stand alone UPS units. They cost too much to maintain and if you don't replace batteries on a schedule they are worthless. Just my 2 cents.

Out of all the devices that I had on at the time of the power outage only the Netgear had any issues. Comcast cable modem, fine. Vonage IP phone device, fine. Netstorage drive, fine. 2 laptops, fine. Flatscreen TV, fine. AV Reciever, fine. Blu-ray Disk Player, fine. I am sure I am forgetting a few things. Seems like Netgear needs to provide a little better protection to me.

Other than that I have been very happy with the device.

most last 5years and you go local supply and get cheaper than you would by from APC parts.

Most of these small electronics use 12V supplies. USB hubs usually use 5V. I've got a deep cycle marine battery I use to power my router and DSL modem. It's a bit of a hack job, but it is much cheaper than a UPS and lasts far far longer.

Marine battery? You sure you got enough current to run all those devices?

If you are off the grid I would say it will most the safest but also you need protect RJ-11 fro surge spike too. It can damaged through RJ-11 or spike from other devices that connected via ethernet can also kill the router as well.

To be honest this sounds like the same problem I started a separate thread for...

My SSIDs show but I cannot connect to them. In my case it was a brand new WNDR3800 router (upgraded to 1.0.0.38), and I eventually returned it after even using TFTP to reset the firmware did not fix the problem... I exchanged it for another WNDR3800, and ran into the exact same problem on that one as well...

In both cases the problem did start after I had powered down the routers in order to move them...

I'm wondering if this is a firmware issue with the WNDR3800 and 1.0.0.38, where powering down the router destroys WiFi functionality completely...
