high cpu usage on gigahub

Gptechman — Sat, 30 Nov 2024 05:17:50 GMT

anyone got high cpu usage on their gigahub? since update 2.13 it always been high, this is unusual
cpu load has technically never gotten high since i signed up for fiber, but now it its unexpectedly.
yesterday I've seen the bar go up to 90%

Thank you for your question. Are you seeing any symptoms of the modem malfunctioning? If not, it's probably not something to worry about.

Hi there @Gptechman
Thank you for your post.
It is sometimes normal for the CPU usage to fluctuate. It's generally not a concern and should not impact your device performance. The CPU usage going up could be from a device that was connected resulting in the modem providing a high load temporarily. The CPU usage should reduce on it's own, a reboot may reduce it or you can also remove all your devices from your internet connection and connect them one by one to see which device may be increasing the CPU usage on your modem.

it is not normal it's always above 50%, last night I had tested the speed via speedtest.net and the wireless speeds were so poor with nothing connected as well as most tests kept failing, I also have a factory reset twice. so this new firmware has bugs and performs worse then before.

Hi there @Gptechman
Are you able to perform a speed test directly through the modem and share the results?
Can you also share which package your subscribed to?

im subscribed to 1.5gig

Thanks @Gptechman
Are you also able to share a speed test result that shows the poor speeds you mentioned?
Do you happen to have your Wi-Fi bands splits up between the 2.4 Ghz, 5 Ghz and 6 Ghz?
Does the indicated speed result of your device change when you are closer / further away from the modem and can you also share which device you are using?

unfortunately I've accidentally deleted the results from Mike last night yes I have every band split and chose the cleanest Channel and testing on a Galaxy s21 I also tested on other devices with 13th gen computer with intel ax 211 card at 5 ft away in line of sight i pulled only around anywhere from 110 to 370, and just before I commented I ran speed test and couldn't get past 500 no matter how close I was

yes all the wifi bands are split

What is your speed test when using a wired connection, and what is the CPU usage when doing a wired speed test?

Hi there @Gptechman
It's possible one of your connected devices is causing the modem to put in higher loads, causing the CPU usage to increase. The best thing to that we'd recommend is disconnect all your devices from the network and once nothing is connected except for one device, check the CPU usage to see what it's at. If it's low, gradually connect another device, check the CPU usage and so on and so forth. When you connect a device and you see your modem CPU usage increase higher then expected, it would determine which device is causing the CPU usage to go up.
As for speed test results from your modem to device being slow, your modem CPU usage percentage should not cause any device performance issues.
Should you test out the disconnection and reconnection of devices and find one that causes the CPU usage to increase on the modem, please keep the Community updated.

no, i also tested last night with nothing connected and wifi disabled it still hovered around 60%

Re: high cpu usage on gigahub

dks — Fri, 06 Dec 2024 13:28:10 GMT

Yes, I have a similar CPU usage number. 71% at the moment. No other issues.

I'm experiencing the same. This morning, I had to reboot the GH because its CPU was at 100%. I was able to connect to the modem to see this information. but then after a couple of minutes the modem page would be unresponsive, no content would load, and I needed to restart the modem.

This has been an ongoing issue for the past 3-4 months... I feel like I shouldn't need to reboot the modem to solve this issue. Once rebooted. I'm fine for 2-3 weeks, then it requires a hard reboot.

Firmware 2.13

Thank you for your feedback. No, that's not normal. How many devices do you have connected to your Giga Hub? What is your speed profile?

Re: high cpu usage on gigahub

Vanadiel — Fri, 06 Dec 2024 14:38:50 GMT

Looks like a maxed out gigabit connection at 945 Mbps. Ping times look normal also.

The CPU load is abnormally high though.

I don't think the home hub has a command prompt. If it does, it should be easy to figure out which process or processes are causing the high average CPU load, by using top or glances at the command prompt.

I got a decent amount of devices connected. Though, when it happens, it often happens early in the morning or during the night, but around the 3-4 weeks mark after a restart. At that time, only my Synology NAS and a Linux laptop (plex) are running, along with a decent amount of Wi-Fi devices like thermostat.

I deactivated uPnP... how can we troubleshoot this further ?
also worth mentioning that were Bell customers since they added Fibre to the neighbourhood and this behaviour only happens recently, like 3-4 month ago, and I don,t recall adding or changing anything of relevance to the network.

it becomes so unresponsive that the modem web page is no longer sending any data !

I don't believe it has a command prompt, so it will be difficult to further troubleshoot this issue on your end.

It would be something someone from the Bell firmware team would need to pick up and look at, as they must have the ability to get to a command prompt to see what processes are taking up all this CPU time, and why.

For example, on my Mikrotik router and can use /tool profile cpu=all at the command prompt to see all the processes that are running and what load they pose on the system.
