Help with reseting edgerouter lite please.

I couldnt not login the router throught 182.168.1.1

I did manually set my pc ip to 192.168.1.2 and router to 192.168.1.1

Search online said hold the reset key to reset. The led on eth2 will go from flashing to steady. Then reset will began. The light never go flashing.

How else i can reset the router. Anyone can help me please...

Thanks
Sam

Get a console cable, connect it to your computer and see what happens when it boots. (Or just cut up a patch cable and make one, same pin out that Cisco routers use).

My first Edgerouter died due to a failed flash memory drive. Boot loader started just fine, but would hang with read errors from the card.

I had a similar issue a few years back, as @Aredwood said, the flash memory of the ERLite was dead.

Inside the ERLite, the flash memory is actually a 2GB or 4GB flash drive. I opened up the ERLite and checked the physical dimensions of the original flash drive and bought a new USB drive that can fit, and flashed the new drive with an updated firmware.

You can google it and find some instructions about it.

Unfortunately the original flash drive of the ERLite is pretty bad (a known problem).

Rj45 to rj45 or Rj45 to dp9?

the new usb is now dead, i gave up fixing, it might be something else rather than the storage.

after i fix it and put in all the configure, it works well for about 10 hr, then i found error 500 when i try to login.

maybe it is time to have a new router.

I have had the power adapters for both my ERLs die, so check if that is the problem. Jaycar has a compatible one - just check the label on the adapter for the correct specifications.

When setting things up in an Edgerouter, if you are doing something that will write data, you must ensure that you are not getting it to write to the USB storage. For example, if you run tcpdump and store the results, and you do that to the USB, it will die rapidly. USB sticks are not built for frequent small write operations - they wear out. Just a few days of operating with writes to the USB stick is enough to kill it. In my ERL, I use /var/log as a good place to write things to, as it is on a ramdisk. But anything written to RAM will be lost on a crash or reboot, so it you want to write data and keep it across a reboot, then you need to send it to another box for storage. For example, you can send log messages to an external syslog server. If you need something more than just messages, you can pipe the data to another box using standard Linux piping techniques.

the new usb is dead same as the old one, could read part of it from PC, but error during formatting.

i gave up on the idea of changing USB, had killed three usb so far, it is not worth doing it if i dont know how.

has gone back to fritz box until i found a replacement,

I had the same problem of not being able to get another USB thumb drive working. The ERL boot loader kept on failing to detect the new drive. But the new drive would work just fine in Windows. Maybe the issue is similar to the Winmodem problem from back in the dialup days. Where cheaper dialup modems used the host computer to carry out some processing functions. And such modems wouldn't work in DOS, Linux etc.

I solved the problem by just buying a new ERL.

I still have the old one, so hoping to eventually find a drive that works. And get that ERL going again.

Remember - as it runs Linux the flash drive is also in the Linux partition structure - you'll need a Linux PC to read it (or the correct library's on Windows). Otherwise, it'll just come up with a message stating you need to format.

The last drive i put in, it has the edgerouter up and runing.
It worked for 8ish hours and i found out it stop when i tried to log in but has error 500 once enter id and password to login.

Then i tried the same trick. Didnt work, error came up when i tried to flash the os into the usb.

Fritz.box is great but has some internet drop through out the day. Is there any rock solid router you recommend apart from edgerouter, Michael?
Thanks advance
