Internet Connection Problem

Last Monday, my husband asked me to call our internet subscriber because there something wrong with our connection. It’s not a big problem though, but there’s a slight delay with the connection. It’s very noticeable because we never had any problem with it until last Monday. So, I called and the customer representative immediately detected the problem. He told me, that I will just have to wait for their action the following day. But after a few minutes, the connection was already okay. I guess the problem has to do with our telephone line. Maybe the fiber optic cables needs to be replaced particularly the lc multimode. I hope I can no longer experience problems with my connection in the future.
