We recently had a tornado in our area, which knocked out service to a lot of Xfinity customers. I had been using an Arris modem connected to a Netgear Nighthawk modem, for several years, with very little to no problems, until this happened.
Not being a novice, but far from being a tech geek, I had set up my own home network without problems.
After the storms & when service was restored, I began having connection issues. After doing everything I knew to try to correct them, I gave in & called xfinity for "help". They had informed me that my modem had reached its "End of Service Life".
I ended up purchasing a new Netgear Modem & connected it to my Netgear Nighthawk router, booted up & was running ok for several hours. Then I began having connection issues. Netgear Genie would tell me I was connected & had a good or excellent signal, but my pc's would all tell me No Internet. This has now been happening several times a day everyday.
I also have Vonage Phone. Sometimes I lose just internet access and other times I also lose the Vonage as well.
Can this be a problem inside the new modem? Xfinity tells me my modem is online and everything appears fine. I am suspecting that it could be some kind of internal failure in my new modem(I had a brand new modem bad out of the box before), and this seems to be the same type of issue here now.
