My optimum internet keeps disconnecting and connecting constantly?

We just switched from Verizon fios a week ago, maybe sooner, and recently I noticed that I can never STAY CONNECTED to the internet. I first noticed it while I was on my Iphone. I see the Wi-Fi symbol flip on and off from 4G to the Wi-Fi waves. Its a nuisance because I can't even use the internet on my phone. (Mind you I don't have unlimited data so using the 4g adds up!) While on the computer, I see it connecting and disconnecting. This happens constantly AND consistently. It will probably happen more than 1 time in 10 min. It's very aggravating. My sister could not even get to question 3 of her final exam due to this poor excuse for internet! I don't really know what is going with this internet (and I have no experience with this whatsoever so I apologize if the solution is clear) But if anyone can shed some light as to what I should do or explain (in simple words! I don't know the counterparts of the computer!) I would deeply appreciate it!

Optimum Online got serious problems with DNS servers, they disconnect you for few seconds and reconnect… For now is no solution, only if you have your own modem and the same using without router… This problem is only in some areas, i wish i have Verizon available in my area, that would solve the problem

  • Internet on my iphone keeps disconnecting? Okay so i have the iphone 3g (yes, i know it's old, please don't remind me) and everytime i use it i clearly have internet. The only problem is after about a minute my internet shuts down, this happens every single time. I can't use the phone more than a minute without my internet shutting down, most times it just says "no service" on the top… Which is crazy… Any help will be appreciated.
  • Stupid iPhone 4 keeps disconnecting from Wi-Fi? Whenever I'm online my iphone completely disconnects from the Wi-Fi about every 3 minutes. I'm just about ready to throw at a wall and stomp on it. It's updated to version iOS 5.1.1 what the hell is wrong with this piece of sh*t?
  • Optimum Wi-Fi works on iPhone but not on macbook? Ok so my friend gave me his optimum Wi-Fi about a month ago. It's been working great but today the Wi-Fi stopped working on my MacBook Pro. It works fine on my iPhone PS3 and tablet. What's the problem?
  • My iPhone keeps disconnecting from the Internet, why? I keep connecting it to the Wi-Fi and then it disconnects. I just got the iPhone 6+ and it never happened with my iPhone 5 or any other product in my house. It works at my cousin's house though. Could this be a problem with my Wi-Fi and not the phone?
