Reset: No
Status: Installed today, OK.

Everything connected in an instant.
No new entries in oops Partition.

Had to restart this router one time after installation, cause some devices were slow, like "almost reaching 10Mbit/s" over 2.4G WLAN after Firmwareupgrade.
This seems not to be related to "Legacy Rates (11b) set to on or off.
Since in last release I encountered the same and disabled this, only for the problem to reappear now.

After this restart however? Everything fine, fast and maxing out WLAN!

Hello to all,

I think there was a bad flash problem, but wanted to bring it up just in case...
I always flash the lastest on my "vpn" router that has the least config so easiest to replace and do by hand if something goes wrong...

Flashed 62508 onto it and I thought it went okay.
I was not connecting to it today and noticed that there was no light on..on the top of the router yet it was on. Was unable to connect to it as it was not broadcasting wifi and failed to connect via lan so restarted.

On restart, it came on with regular light pattern and then when normally it would go to green light, it instead went to red light and again, was not broadcasting or could not contact via ping or open gui page. Thought it might be bad flash or something broke after a certain period of time.

So i power cycled 2 more times for a total of 3 to get other partition...booted right up and was back on 10/30-62460..

heres an interesting part. I retain all the associated files for about a month just to see what happens. I looked at the flash file that I downloaded on two different computers at approx 11/2 3:30pm local time. Both copies of the 11/2 were the same at 69,637 kb which was what I used to flash. Today when I downloaded the same firmware, it was 71,941. So perhaps I caught a version update cycle or something and didnt get the complete file or there was a change to the file in replication on the server side or something...but the files were different and basically the ones from 11/2 both had successful download messages...Dont know what happened there but noting it in case I just lucked out and caught it at a different version or something.

Anyway. I went to commands and found out what partition I was on...
