[N900 CG4500BD] WiFi keeps dropping
First of all I'd like to thank everyone for reading this post. It helps out a lot!
I recently purchased a new N900 CG4500BD on Amazon for my house. Prior to this, I had the Ubee DDW365. It was working fine for the first week, but then I noticed the firmware for the actual modem/router combo changed itself. Ever since it changed, the WiFi has been dropped randomly, or under heavy use. This usually happens after dinner.
When I tried self activating it, it didn't give me the option for the CG4500BD, even though it's a cox approved modem. So what I did was chose the CG3000D and just put the serial number and mac address.
Things That I've Been Noticing
The first day I had it, the interface itself (192.168.0.1) looked something like this
After a few days or a week, the interface changed to this (actual screenshot):
Ever since the interface changed (I'm assuming it's a firmware downgrade), my internet has been going down ever since. The interface does not give me an option to upgrade my firmware.
I've been noticing that this usually happens sometime around dinner time. But it also happens when its under heavy use (such as watching a movie, or running a speedtest). What happens is the lights on the modem stay the same, but both WiFi channels go down, and the only way to make it work again is to unplug the router and replug it back in. But then, the same cycle happens again.
I noticed that the Netgear Genie app no longer works and I no longer have the netgear genie interface.
What I have tried to do
- I've reset the modem plenty of times.
- I've power cycled the modem plenty of times.
- I called Cox and asked them if they could change the modem that they have on file so that the firmware on the modem/router could change (read what I did with self activating above). They changed it to I believe a several other modems, such as the N450, RNC3700, and some type of AC model. It hasn't helped in any way.
- I tried changing the channel on the 2.4GHz network to channel 1, 11, and 9.
- I tried changing the channel on the 5GHz network to any random channel.
- I tried looking for firmware updates but I believe this isn't possible because the firmware on the modem/router itself is locked.
- Maybe changing the firmware back to what it first started with will help. I had no problems with the firmware it first started off with, but once the firmware changed and once the interface changed, I've had problems ever since. Somehow I need to get this specific modem (N900 CG4500BD) on my account. What I currently have on my account is a RNC3700.
