NETGEAR CM 1200 Cox Gigablast Speed Problems
I set-up a NETGEAR CM 1200 after having the Wifi Panoramic. Decided didnt want to continue renting from Cox. I'm using an Orbi RB20 Router.
It's strange when I run a wireless speed test on MacBook I'm getting download speeds all over the place from 20mb to 350mb. Upload have been constant between 25mb & 40mb. When I run speed test on the Orbi using the Orbi App on iPhone I get download speeds around 550mb and upload speeds around 40mb consistently. On same iPhone using the Okia Speed Test app speed test is around 250mb to 300mb with upload speeds around 35mb.
My speeds on MacBook Pro drop as low as 20mb sometimes and have been ranging between 20mb and 350mb. I contacted Netgear and they said problem appeared to be the Upstream Bonded Channels 1-4 are locked but 5-8 are unlocked. All of the downstream bonded channels are locked.
Cox Reps (I spoke w/2 on 1/3/20) says they don't provision 3rd party modems. Netgear saying they cant lock channels 5-8 which is what they say problem is.
Do I need to just return this modem and go with Arris CM8220? That is what Cox representative suggested.
