TLDR; Optimum has to be the most negligent, inconsiderate, and worst ISP I have ever dealt with. They do not care about their customers and support will lie and push other products on you. If you don't accept they will be rude and neglegent to your issues.
The only pro I can give them is when my internet works it works decent. I pay for 1Gig. Now I understand with it not being fiber, how many devices are connected etc. I won't obtain those speeds, but I do get an average of 500-700, WHEN IT WORKS.
For over a month now I have been dealing with constant service interuptions. Literally over a dozen times a day and I truly wish I was exagerating that number. Outage time ranges from 30 seconds to 30 minutes. Our service has had random disruptions frequently over the 2 and a half years we have had them, but never this bad. I have been on the phone, in chats, and even in stores trying to resolve this issue. My wife and I work from home and it has severally hindered our work lives. It tooks over 6 different attempts to get support before them being willing to send out a technician. Everytime I spoke to support they would run a test and the internet would be "Operating smoothly" which after waiting for 20 minutes on hold or for a rep in chat makes sense as its random and does not last long. The technician came out inspected and replaced all connections and wires. He also recommended a new Gateway as ours had lights on that were not suppose to be on. The tech also stated he is not sure why support would be saying our service was fine when it clearly wasnt. He also said their modem/router combo was terrible as a router and recommended a mesh system. With his advice in consideration we decided to buy a nice mesh system to hopefully alleviate some of my wife and I's issues while working by placing nodes in each of our offices.
After replacing every readily available hardware we are still unable to stay connected and now when we speak to support they claim it must be an unreported outage. After going to the store to replace the modem I was 1 of 4 other individuals in there experiencing the same issues. I was instructed at the store to time it right and get support to test it while having issues. During all 4 of my attempts to "Time it right" I was offered their mobile services and only 1 of the reps was considerate of my initial denial. The rest continued to be pushy and when they finally accepted no offered almost no assistance to my issue and would just disconnect.
If I could swap ISPs I would, but sadly the only other options I have are satelite and they dont offer well enough speeds for our jobs or a fiber company, BUT my landlord will not let us run a fiber line through the property.
If you made it all the way through my story my advice would be to try a different ISP if available and stay away from Optimum. If you cannot then I am sorry for your struggles and I am there with you
Now... que the generic scripted BS response that someone from Optimum will write as a comment. read more
