Netgear 3700 Router, Hardware/software problem?

[joelm335]

I have a Netgear WNDR 3700 V4 with Gargoyle 1.8 installed. It has worked perfectly for 3 years in a rental property but has developed a fault. It goes through power up routine. All correct lights com on, it will connect with the modem and briefly (10 secs) with the internet. Then all lights on front flash yellow, go out, and it goes through the power up routine again. I have tried connecting to PC with an ethernet cable and got as far as entering password but no further.

Any suggestions? If it is a hardware fault, I will just replace it as have had good service.

You can try a "openwrt Failsafe reset"

or

"serial cable" to try and see whats going on

but I suspect it might be time for a new router?

I'd try different PSU

It's likely a time warp bug. viewtopic.php?f=12&t=10912

Thanks everyone. Sounds like it could be the Time Warp Bug.

I already tried the router with the WAN disconnected and it still continuously reboots itself. Not enough time to log into the GUI interface. We have guests staying. When they leave I will try to start in failsafe mode.

Got into the GUI and deleted all data in Bandwidth. It’s stable with WAN disconnected. It seems like it’s stable when I plug the WAN cable back in but as soon as I connect to it by Wifi and connect to the internet, it quickly reboots itself.

Edit: will stay connected for most internet browsing. Running Speedsmart speed test crashes it when it starts to test upload speed. ????

Ideas? Or is it time for a new router.

gargoyle factory reset first

Hi you can do a reset by flashing a updated build and unticking the box to save your configs (settings).
