Hello everyone,
So this restaurant had an issue with their network going down and reason for that was because they needed wifi, so they decided to install a wireless router on their own. The way it's setup now is: Comcast Modem/router --> 16 port switch. They plugged the wireless router into the switch. Not sure when it was done, but I know everything worked fine for a while. All of a sudden they lose connection on the other computers one night and I figured that if 2 routers are plugged into the switch, that that means they are both trying to give out IP's.
What I did next was I got them an AP and took out that wireless router. 2 issues with the AP now. First issue is, when I plug it directly into comcast, it doesnt work. I plug it into the switch and it works right away. Anyways no one complained about anything till 2 days later. Then I was told that the credit card machine went down after I left. I never worked with the credit card machine, but they said once they unplugged the AP, it worked again. Im really confused on whats going on with this network. I plan on getting it all fixed up this upcoming weekend since the person who did that setup is not working there anymore.
Any ideas on what could be happening?
