Wireless Interface disappeared on RB2011

This device has been running for over one year. I upgraded to 6.20 about 2 weeks ago? Suddenly, it started acting weird. It lost the password, then would not keep any changes to the password for more than a few minutes. Other changes stuck. CPU Utilization was 100%. Then, it said no hard drive space available. I removed The Dude (was not using it). After a reboot, the wireless interface disappeared. It will not come back.

Suggestions?

See to “system” “packages” see you “wireless packages”?

Yes, I can see the wireless package.

Support indicated I should use netinstall. I will do that. Right now, I need a usb to serial adapter, for my only Windows box does not have a serial port… will update here.

Why to use serial cable if netinstall works over Ethernet as well?

Plug in the Ether1 port to a PC, launch the Netinstall tool, then start the RouterBOARD device while pushing the Reset button. When Netinstall tool sees the router, release the button. No need for any serial cables.

Here the step by step netinstall procedure.

Thank you for the info. I appreciate it. The following comment is not because I am ungrateful but instead, I assume it would be helpful to many other people


Perhaps it is time to update the manual to be more accurate for it indicates a serial port is required and step 2 tells me to connect the pc to the serial port. I had assumed the manual was athoritative. I was referencing:

http://wiki.mikrotik.com/wiki/Manual:Netinstall

you are right. I have simplified the manual now, and have removed the implication that console cable is needed. I also have now added “optional” to the COM port section.

Many topics in the wiki are unclear.
But this is clearly brought.
Thanks Normis great job.

I followed the instructions. Frankly, I am not certain whether netinstall did not work properly or whether using netinstall did nothing. I say this because I follow the manual and I am told a Reboot button will replace the Install button in the GUI, this did not occur. So, I did a reboot by pulling the power. See images. The “installing” image occurred before the “ready.” The timestamp used for the filename of the images is accurate.

After the reboot, the wireless interface did not appear.

So what failed, the router or netinstall or both?

Try netinstall again with all-packages.

Same result. See images. I am guessing that the netinstall failed, for it does not take long.

Disable “keep old configuration” and try than again.

Okay, I wound up having to reset the configuration. This method did WORK! Thank you. Of course, it really sucked to setup the router again. I had a backup config from the other day, which expedited things. It still took quite awhile. I love the /export command, but inevitably, the order that things are exported will not work for copy/paste and getting the router to work.

Once again, thanks. System resources are much more normal now.

Thanks for giving me karma great!
