Problem modem-router

https://imgur.com/a/01XuM

Pictures above show the following:

Top: modem
Bottom: router

Yellow cable: connected from output to laptop for troubleshooting

Gray cable: connected from modem out to WAN on router.

Laptop connects to router, gets ip etc but router and modem seem to not communicate. Both lights don't blink at all and stay permanently lit.


No clue what I'm doing wrong.

Got this error - would it help to reset router/modem?

I see a tg670v2

In reply to: Problem modem-router

It looks to be a modem+router combo unit. The unit above with the grey cord isn't clear what it is. As such I need to ask you what the top unit is but I see DSL so the top unit is some DSL+modem+router.

The setup as shown should not work as the second unit is not a router.

Tg670v2 is indeed the second one. First is a technicolor a-mod 3.

Any ideas how to fix this issue?

I was unclear.

To fix this you would add a router. Those two devices are combination modem+router+possible other things.

There are folk that claim to turn these into rotuers but here, I stick with the documents for the products and for this round, you do not have a router box. Other things, but no router in a box, plain old router.

The thing is, it does make a WiFi network and such. Problem is that it doesn't reply to what my pc is sending it even with direct connection.

Unsure how this helps.

I looked at the products and didn't read anywhere you would use it as a router. Anything you do with these outside what's in the manual is not supported.

Since you already have a router, use the second unit as a WAP. You won't use the WAN port but the LAN port. The WiFi there may be non-functional but it's a step in some direction. Google "How to use a router as a WAP" for more but again, since it's not a router, it shouldn't work.

The problem is that neither of the devices has access to the internet.

Your top post didn't state that.

In reply to: Reply

So forget chaining these together.

DSL modem+routers need to be "provisioned." That is the modem+router needs to be configured for the ISP you are using. I will not have those settings. Contact the ISP to fix that.

connections look good.

In reply to: Problem modem-router

The connections seem propperly made
but i do see that the yellow does lit up on both ends means the devices communicate
by your description modem to computer
computer is getting the ip address most likely the routers ip but the router is getting none from the modem
swap the ends of the gray cord and see if the lights come on, if yes it may be that the cord came loose somehow or dust or something may have been preventing it from making propper contact if still no change swap the yellow cord for the gray and see if the modem comunicates to the router
if still no change on both ends you may need to change one of the 2 devices.

Problem modem-router

In reply to: Problem modem-router

Try to connect the white cord to the white slot... from modem to router the DSL port. and why you need to connect your router to your modem... your modem is like a hybrid type i think its modem-router... you can directly connect your pc or laptop to the moden... but if your looking to configure your modem read this to guide you.
