I'm facing some weird issues with JioFiber and my homelab. Sometimes (randomly), my homelab's internet connection becomes extremely slow and unreachable/unresponsive for 1-2 hours twice a day. And this happens at random times! sometimes exactly at 12 AM, sometimes at 2 PM, and it lasts for about an hour or two. During this period, I can't ping the homelab, and the homelab can't ping anything else either (example: if I ping 1.1.1.1 from homelab , it shows error unreachable, and if I try to ssh my homelab, it says "no route to host"). and the weird part is that this issue only happens on my homelab. All other devices connected to the network remain unaffected and work at normal speeds! But except for that time interval (around 5-9 PM) the internet speed of my homelab is completely normal (30mbps).

Some information about my homelab:
  • runs debian 12 (headless installation) and I access it via SSH.
  • running 25 docker containers, including the *arr stack, and I'm torrenting without VPN (except for Prowlarr, which uses ProtonVPN with gluetun).
  • I'm using NetworkManager, with DNS set to 8.8.8.8 and 1.1.1.1.
  • Tailscale is installed (MagicDNS is turned off).
  • I'm using iBall's wireless USB WiFi dongle to connect to my router.
This issue only affects my homelab, not other devices. What could be causing this, and how can I fix it? I've tried turning off client access control (as mentioned here) but it didn't work. I torrent sometimes with *arr stack, so is JioFiber throttling only my homelab for some selected time intervals? are there any settings in the admin panel that I should check? I reset the router three times, but there was no difference.

Hello sir
Welcome to the Broadband Forum, I would try my best to help

I seem the issue with jio provided router as I also run various docker containers with same ProtonVPN with gluetun
Here I have replaced my jio provided router with my own (TP-Link's XZ000-G3 v2 and Xiaomi BE5000)
I suspect the your router is using isp provided DNS servers which can get overload anytime or at peak
But, recent update to all jiofiber router have blocked changing DNS completely making it questionable for reliability
Make sure to get as much as ventilation to the router
Lastly run a ethernet cable to the homelab or get better usb wifi or use pci wifi for more reliability
 
Thanks for the response. The issue is only happening with my homelab and not with other devices, which is a bit weird. If DNS servers were overloaded during peak hours, all LAN devices should be affected. But in my case, it's only one device (my homelab) is being affected.

The same thing happened yesterday, and I got really frustrated; during the outage, I unplugged my iBall usb dongle and plugged it into another usb port. Suddenly, network on the homelab became completely normal and fast (50 mbps).

Turns out there was some issue with my usb IO port, which is still unknown (and I'm not interested in finding it out either). I've been trying to solve this issue for the past three months and spent a lot of time on it, but it turned out to be such a small problem lol.

About the router, I'm planning to get a thinkcentre next year. I'll install proxmox on it and run a pfSense VM, a pi-hole LXC container, and attach a switch to use it as a router.

My issue was resolved just 15 minutes after your reply :P
 
What kind of hardware is your home lab? I'd suggest trying a different cable, or it could be a bad Ethernet port.
I'd also propose, refreshing the drivers for the Ethernet port or checking for any updates.
Last but not the least, power fluctuations can sometimes also cause a hardware to lose network connectivity intermittently.
During this time, your parent OS/HVZR might have frozen. A good way to verifying will be the hardware logs.

EDIT: I just read now, that it was fixed. Since the culprit was the USB, this could mean power issues.
 
@Myself I am using 2.57 firmware on JCOW414 and I am able to set DNS without any hacks. I have changed my DNS settings in the router to point to my self hosted Adguard Home installation that I am running in my home lab. What version are you using that doesn't allow setting dns server?
 
@hacked2.57 i might be outdated (if yes, i apologize for that) but after that jio update, many people says that jio have removed access to change DNS in wan ipv4 and ipv6
What version are you using that doesn't allow setting dns server?
Click to expand...
not tried it, it has been a long time that I abandoned JHGR since july and i need to check that
 
@hacker2.57 well personally i had better experience setting the wan dns to Cloudflare and since then i had never had huge issue while using especially while using tailscale and peer to peer file sharing. Also other user also complaint that jio dns is not that reliable during jio having ipv6 problem while back. Basically telling the router to use the dns, leaving lan dns empty will force all user to use wan dns to process the conversion of internet traffic.
while using lan dns telling the router to all local network to route all dns request to router or firewall like pi hole then it handover to the set wan dns to proceed
Lastly setting wan dns other than jio dns helped to access some websites that were blocked by jio dns for no apparent reason
