Network Card problem

Out of all scenarios, out of all bad things that can happen to my MT-BOX… this is THE WORST¡¡¡

I got a Hotspot up and running, It was working strong¡¡¡ but then…

I was remotely monitoring the network data flow using a netflow monitor when all the sudden…
ALL THE TRAFFIC DROPPED TO CERO¡¡¡¡

I accesed my MT via Winbox to find out that all the hotspot clients suddenly dropped…

I rushed to check my MT box and I find out that the Hotspot interface was behaving rather strangely…

This Network Card is integrated to the Motherboard, its a VIA based NIC… both leds in the card where turned on solid but… the led in the switch was off… I unpluged the cable from the NIC and… THEY WHERE STILL ON¡¡¡… so… i shutdown the system, unpluged the power cord, pluged in again, turned on the system, pluged the cable again… the card seemed to work allrigth… I walked home thinking that the ploblem was solved…

Next day… all was working fine… but… my network speed was lower than usual…

I replaced the ethernet cable going from this card to the switch… the network speed got up rigth away¡¡¡

In any case… WHAT SHOULD I DO IF THIS CARD TURNS OUT TO BE DAMMAGED???

WHAT CONFIGURATION ARRENGMENTS I HAVE TO DO TO USE ANOTHER NIC FOR THE HOTSPOT WITHOUT HAVING TO RESET THE ENTIRE CONFIGURATION???

PLEASE HELLP ME… I AM REALLY PREOCUPIED ABBOUT THIS¡¡¡… :open_mouth: :open_mouth:

Normis, Sorry abbout the odd title name :blush: :blush: I promise It will never happen again.
I fixed the problem¡¡¡ I typed on console:
1.-

[admin@Mikrotik] > export file configuration

2.-Then I used winbox to download this file (configuration.rsc) to my computer.
3.-I oppened this file with MS-Word, searched and replaced the name of my damaged card with the name of the new card (Not all of the matches¡¡¡ you have to see witch ones affect you)
4.-When I got a picture of what it was required to be modified, I did the modifications using winbox.
I know there is a better way of doing this, but this worked wonders for me, now my network speed is basting STRONG¡¡¡.
I still whant to know who was the guys/girls who came up with the Idea of making RouterOs, HAIL TO ALL OF YOU¡¡¡ MIKROTIK ROCKS THE WORLD¡¡¡
