CM1000v2 and RAX54v2 fluctuating download speeds. I go from 900mbps to 30mbps randomly.

I've already contacted my ISP and was told that everything is fine on their end. I've switched out all the ethernet cords to no avail. Any help would be much appreciated.

Thanks for the info. I had my ISP come out and they checked and changed the COAX cables. Said I wasn't getting any power and that one of the cables was dead. So far it seems to be working. I'll watch it for 24hr to see if it dips back down or not.

Please post a copy and paste of the modems connection status and event log page.

Is this over a wired or wireless connection for these results? Wireless could result in varied results. Wired is recommended.


Do you see same when ethernet connected directly to the back of the CM modem with out the router being online? 

Compare with different device or PC to see if same thing is seen there as well.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 

 

What Firmware version is currently loaded?

Thanks for the quick reply Furry. I am currently at work so I'll get that information once I get home. I have tried bypassing the router but plugging directly to the modem with a cat8, no change. It happens on both wires and wireless devices.

Ok, if it happens directly connected to the modem, then ISP needs to review what I posted about.

For the Modems Cable Connections Status it says it's good. Did you want me to copy and paste those charts under Cable Connection?

Re: CM1000v2 and RAX54v2 fluctuating download speeds. I go from 900mbps to 30mbps randomly.

Also I forgot to mention earlier. When I restart the modem and router, the speeds are fine for a minute but then they'll start to slow down.

Re: CM1000v2 and RAX54v2 fluctuating download speeds. I go from 900mbps to 30mbps randomly.

Ok. You have tons of Correctables and Un-correctables that should be mostly zeros across all channels. 

 

Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.

 

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

Thanks for the info. I had my ISP come out and they checked and changed the COAX cables. Said I wasn't getting any power and that one of the cables was dead. So far it seems to be working. I'll watch it for 24hr to see if it dips back down or not.

Glad you got it working. Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
