Hi i work at a coffee place in argentina , and like i am the one who knows more about tech i have to fix an issue with the modem/router that the isp give us ( it worked well untill now) some guests complain of the slow speed of the wifi and others could even conect to the wifi it give them an error obtaining the ip. So we bought an ap the ac little from unifi , then the problem was worst , we call the isp and they said it was a cable issue so they change all the conection from outside . That didn't fix the issue , so i tried doing a ping with a computer coneted by ethernet to my phone at the new ac and it take a while to complete it and also lost some package , so i tried with the modem wifi and it take as long to do it but none packages were lost. What i have to do? Bridge mode will help ?
