Home Hub 3000 stops LAN traffic after a while

[man_vs_fauna]

Hi, I'm hoping someone can help understand what is going on here.

I have a #Home Hub 3000 setup with both a normal wifi network and a guest network

For my work, I do testing where I'll have different devices and machines needing to communicate on the local network. Most of the time I'll have them all on the same non-guest wifi network. They will all generally have static IP addresses.

Here is the weird thing, for a long time I had no issues pinging, RDP or communicating with these different devices, then one day it just stopped. It seems like rebooting the HH3000 fixes it for a little while, but then a few hours later it stops working again. All the devices that need internet access can, they can all ping the router and the router can ping them.

I think I have eliminated all other potential causes such as firewalls, them being accidentally on the guest wifi, incorrectly configured IP, etc.

There seems to be nothing in the system logs, so I don't have much to go on.

Not sure how you have them configured as you seem to use static IP's. A problem could be network collisions, or identical IP's assigned to more than 1 device.

One thing to check for is the Guard option, to see if it's turned on or not. This is a setting that is only available using the Wifi app and cannot be seen or accessed from the modem menu.

I thought I had checked this option, but you are right that I should explore this further.

I'm going to set my DCHP range to exclude these static IPs, clear the lease table and then do some pings when those devices are offline. I will report back.

As a follow-up, this seems to be the issue. Setting the DHCP range and releasing the table has worked so far.

Unfortunately, the resolution was not permanent. Even with the static IPs in their own range and DHCP in another, the issue has returned. Again, only restarting the HH3000 to resolve.
