I have a credit card machine that I have connected to the internet via Network Bridge. At first, it was working perfectly without issue for a good few months. A couple of months back it wouldn't connect to the internet and I just disabled and then enabled the ethernet connection to reset it and worked! Now, almost every single morning when I get to work I have to repeat the same process. What is weird is that once I enable the connection, I get the IP conflict popup and that is when I know it is working??? Anyone have any insight on how to fix this issue?

IP conflict means just that. Your credit card machines IP address is conflicting with another machine with the same IP address on the network. What can happen is that you set a static ip to your CC machine 192.168.1.2 and the DCHP server IP scope is set to 192.168.1.2---to----192.168.1.254 this will cause a IP conflict.

 

Typically you want these types of devices to have a static IP and set the routers DHCP scope to be something like 192.168.1.10---to----192.168.1.254 This way you can set devices a static IP 192.168.1.2-----to----192.168.1.9

Yeah I understand the IP address conflict, but how would I set a static IP for a credit card machine. There is no way to adjust settings on it.

What model credit card machine is it? If nothing else, maybe I can look up the default settings. 

 

Also, what do you mean by a "network bridge"? A switch? Wireless adapter? Do you know what model? Also, what device (router?) is it bridging to? If it has routing capabilities, you could add a DHCP reservation to reserve what ever IP the credit card machine is using. This is also assuming the CC machine is doing DHCP.

Sorry, I have it connected to my desktop via Ethernet cable. My desktop connects via wireless adapter and I bridged the 2 connections to give my CC machine an internet connection. Model number is an ICT250.

How did you configure that? What IP info? That isn't the correct way to do it as per the manual:

 

"IMPORTANT: The connections between the Moneris terminal and the modem must be WIRED. Moneris terminals do NOT support wireless connectivity between the terminal and the modem . If Option B is used, also note that the connection between the router and the modem needs to be a WIRED connection as well. A WIRED connection provides increased data security and reliability. 

 

My guess is when  ICS was configured a non reserved IP was used for the CC machine, and now that IP is comflicting with the one the laptop is sometime using.

Thanks Trikein I just logged on. That would definitely be a bad thing and explains the reason. Not to mention that it's probably breaking some credit card standard rules and regulations.

It would be nice to see a ipconfig /all from this pc to really know the config

It is a wired connection via Ethernet cable. The terminal itself does not have any wireless capability, which is what I believe that is saying so of course it can't support it. How could it be violating credit card rules and regulations?

It is hard to say since you haven't described what terminal you have and how you have the computer configured. Either way it isn't suggested by the manufacture.  Can we have that ipconfig? Please?  :hello:

Actually, that is everything! It starts with 2, not 1.

Hmm, maybe that is the problem. Your wireless network adapter 1 is how your computer gets the internet connection to share with the ethernet connection. From the sound of the OP, the ethernet adapter was crashing before, requiring a disable/enable to reactivate. Maybe the same thing is now happening to the wireless network adapter?

 

Try running Minitoolbox and check the boxes for all items starting with "List" and next to "List Devices" pick "No Driver". Copy and paste the log into a reply.

Does not appear you are making a wifi connection.  I am also surprised this ever worked since bridging doesn't create a dhcp server like ICS does.

 

It would also appear your pc is connected to the router not the cc machine from the ipconfig.

 

To really see what is going on you need to connect wired to the cc machine and wirelessly to your router.  Then post another ipconfig /all for review
