Hi Datalink,
I have spent some time with merchant services this morning sorting out the credit terminals issue. I was told that they only connect with a wired connection for security purposes so that explains why having the wifi running is no help trying to process credit cards. That said, they did walk me through what to do, and apparently it was my fault that I couldn't process the cards. I have a telephone line back up in case of internet failure and couldn't figure out why it wasn't working. Reason was that the terminal tries twice to process the deafult way which is internet, and then tries to dial up through the phone line. After the first attempt that came up No internet access, I hit the cancel button so it never got to go through its other attempts. Now I know to just leave it alone until it spits out the paper on its own. We tried it with my credit card for a penny just to make sure it works fine, and it did. Took a long while, but eventually gave the authorization via phone dial up. So that is one good thing!
Now, in terms of the wires on the back of the CGN3. Right now, having done nothing yet, I have one credit card terminal with a solid green light, one with a flashing green light, and then the modem ethernet yellow cable with a flashing yellow light.
I am also logged into my modem now, and the firmware version I see (SW Version it says) is 4.2.4.3. I believe it is up to date as I tried to update it and it said the latest update was already installed.
Regarding the set up USB key thing, you lost me there. lol Yes, one thing at a time. Actually, I used the set up key the first time too and was ok. Didn't have problems with crashing but who knows. Next time I know to use the "Advanced Users" instructions which aren't actually too hard when you've done it once already.
Ok, so I will do the things you told me above, and report now. Finally. Sorry but I keep getting sidetracked with other stuff as I still have to get things moving as much as possible for my customers.
