I was wondering if anyone else have unstable internet on their router?
I explain : my Mango is connected to my internet provider router by ethernet cable and I tried to connect my computer by cable and wifi to the Mango.
At first, it seems that everything works well, I can surf the internet and watch videos. But I noticed the problem when on video calls : every 15-25 seconds, the connexion is dropping for about 1 or 2 seconds.
I tested it to confirm by doing ping resquest every second and indeed it’s good most of the time (100ms ping, normal for my connexion) but every 15-25 seconds I get a ping of 1500-2000ms…
I checked with mutiple devices and I get the same results.
There is no difference if the mango is connected to a WireGuard client or not.
I also checked if I connect my computer directly to my internet provider router and I don’t have the problem.
Did anyone also noticed this behavior? What do you think the problem could be?
I am using the last software version available on the Mango : 3.216.
Thanks for your answers.
Have a good day!
Interesting. Can you ‘ssh into’ your Mango & observe what’s happening to the running processes via
htop? Given the apparent periodic based nature you’ve observed I’m wondering if there isn’t something taking a little more time than it should in executing, perhaps blocking/bottlenecking something else.
This is speculation of course.
opkg update && opkg install htop)
Thanks for your answer.
You might be right about some process taking to much time.
I ran the commands and here is a screenshot :
It seems like the processor is running at 100% sometimes and it could be the problem but I can’t tell which process is causing that…
You’d really have to watch the output of
htop to try & get of sense of what’s taking the most CPU cycles. In the meantime, try killing
gltertf. I’ve noticed it seems to choke the CPU of my Certa (f/w 3.216) a touch more than I’d like. You’ll lose the ability to see client-specific stats related to connected client devices within the GL GUI but rebooting the Mango will return it right back to normal. IIRC:
ps -w | grep gltertf && kill $(pgrep gltertf) && ps -w | grep gltertf
will do it.
mwan3rtmon is another one if you’re not using failover.)
This isn’t a permanent change so it should be a good way to safely test the hypothesis.
Apologies; I must have missed that until now. You can ‘SortBy’ via [F6] →
htop. Then check the
As you suggested, I tried to kill the
It seems like the processor is not running at more than 50% anymore.
I also sorted the CPU column in
htop but I don’t see anything using more than 3-4% of the CPU.
Unfortunatly, I still have the same internet stability problem. Might not be related to a CPU overload after all.
Thanks for your help
You may be right. My Certa has similar specs to your Mango, just the addition of a 802.11ac radio as the key difference, so I that’s what I was basing my advice upon.
There was a 4.3.2 beta1 firmware released 2023-06-04 05:48:35 (UTC-03:00). I wonder if that would alleviate the problem before declaring it a hardware fault?
I did the update with a full reset of the settings and it seems better ! I only have some spikes to 300ms now. Not perfect but definitely usable !
Thank you for your help and have a good day
