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

I am having issues with my TL-R600VPN connecting to the Web, and although that seems to be a common topic on these forums I haven't found a solution that works.

 

I know the device works, because it was working in a similar configuration a few weeks ago... the cable modem is new, but all else is identical. Here is what I've tried:

 

Cable Modem: Spectrum/Charter Communications Model E31T2V1 (not user accessible)

Router: TL-R600VPN

 

WAN is set to port 1

 

Configuration 1: Computer connected directly to Cable Modem. 

DHCP Configuration from Modem:

IP: 192.168.100.10

Mask: 255.255.255.0

Gateway: 192.168.100.1

Result: Success

 

 

Configuration 2: EERO Wifi connected to Cable Modem - acting as router. 

DHCP Configuration from Modem:

Not Visible

DHCP Configuration from EERO:

IP: 192.168.4.56

Mask: 255.255.252.0

Gateway: 192.168.4.1

Result: Success

 

 

Configuration 3: TL-R600VPN connected to Cable Modem - acting as router. Computer connected directly to TL-R600VPN. No other connections (including EEROs)

DHCP Configuration from Modem (WAN 1):

IP: 192.168.100.10

Mask: 255.255.255.0

Gateway: 192.168.100.1

Connection Status: Connected

DHCP Configuration from TL-R600VPN:

IP: 192.168.0.78

Mask: 255.255.255.0

Gateway: 192.168.0.1

Result: FAIL

 

 

So, bottom line: The EERO and my computer seem to be able to do what the TL-R600VPN can't... actually connect to the internet. I can log in to the TL-R600VPN from my computer and see that it thinks it's connected, but trying to navigate to any web page doesn't work. I tried hard coding 8.8.8.8 as Primary DNS, but that didn't help. Tried pinging anything other than the router, but those pings failed. 

 

So, this doesn't seem so hard. What am I doing wrong? This same setup was working fine at a previous location with the same model Spectrum modem. 

 

Only clue I can see: The TL-R600VPN is not pulling DNS information from the modem, while the EERO and my computer did. 

 

Any ideas?
