Model: TL-R600VPN  
Hardware Version: V4
Firmware Version: 4.0.4 Build 20200313 Rel.41831

Hey there how are you guys?

 

Here is my SETUP: TL-R600VPN + TL-SG1016D + Wireless D-Link DIR842 (as an AP)

 

TL-R600VPN + TL-SG1016D 
4 WANs = 1 for each ISP

1 LAN Port that is connected in TL-SG1016D's no.1 port.

 

TL-SG1016D 

Port1 - Connected to the R600VPN LAN Port.

Port #2 to port #14 - Cabled Devices

Port #15 - Conected to D-Link DIR842 (access point) for the wireless devices.

 

 

LAN

IP Address: 192.168.0.1

Subnet Mask: 255.255.255.0

 

DHCP Settings

Starting IP Address: 192.168.0.2

Ending IP Address: 192.168.0.99

 

 

Here is the problem:

I have 14 Devices on cable with manual assingned IP Addresses, DHCP is running only for the wireless devices.

The internet randomly goes down for a wile and some times goes up, or sometimes goes up only after unpluging TL-SG1016D from power (30 secs) and powering it up again.

 

  • When the internet is down I can access the TL-R600VPN configs (So there is communication between the computer and the R600VPN); The "System Status" shows me that all the 4 WAN ports are with "Link Up" status, but no internet navigation at all;
  • There is no Firewall config enabled;
  • Enable Load Balancing is checked - Enable Application Optimized Routing checked as well;

 

Any suggestions of what might be happening on the network?

 

Thx in advance

If the internet drops after the switch is rebooted... it seems like a STP is firing off.  That would be 1st guess... 

 

I would run the devices against a sys-logging server and see what errors fire off.

Just happened here... I've checked the TL-R600VPN log, here is

 

 

No internet at 16:01...  So I've checked the log (below) 

 

 

 

So I turned off the Switch, and turned it back on 30 seconds later, the internet is back! But I don't see any significant changes in the log after restarting the switch (below)

Just to confirm, the log screenshots is from the router?  IF it is, then the router isn't showing any apparently wrong.  

 

Since the switch is a unmanaged switch, I would swap it out with another switch and retest.  Or even swap ports.  

 

The switch maybe failing.
