Router is running a "T" train. My recommendation is to use an "M" train for stability.

Can anyone tell me what is diffrence between this IOS:

 

c2800nm-advsecurityk9-mz.124-22.YB2.bin
c2800nm-advsecurityk9-mz.124-4.XC7.bin

The first one is old.

The second one is a lot older.

I was thinking in technical terms what the is difference  what are XC7 and YB2, but thank you.

I put on router IOS  2800nm-advsecurityk9-mz.150-1.M10 and work fine for now
