Hi one of our tills keeps crashing.
And sometimes after switching it off and on the RAM resets.
Rather annoying.

So now I have a 'default till'. - NO PROBLEM! Easy fix right!?!?

NO!

I went to put the IP address in so I could do a "Push ALL Data" from another till But low and behold.
The network adapter has stopped working.

Now a long time ago I remember having to clear the cache on the adapter to reset it.

But can't remember. Any ideas?
