Isp dhcp not functioning properly

[lior1111]

Sitting around trying to connect to my asus router for the past few hours and need help.. 

I have my isp router+modem working just fine. But i wanted a better router and so i bought the rt-ac1200g+. 

It worked perfectly for about a year or two. Then i started getting alot of disconnects and reconnects, basic internet issues. My isp told me to not usr that asus router and connect only to their product. It works now after also the isp router being replaced to a new one. But i cant help but feel that the asus router can be bought back to life, so i went back to the asus, made the isp router operate on bridge mode as a modem, And i am now connected to the asus router again. But no internet access. Ive tried playing with the asus settings a bit, went through the automatic wizard and all and i cant get rid of this error message: your isp's dhcp does not functioning properly. 

 

Now, i doubt its that the isp disabled bridge mode or somethin because it was working before, im leaning towards the fact that i replaced the isp modem to a new one and now the asus router is kind of not configured for this new one but for the older one i replaced. 

Any thoughts? 

Thanks upfront!

Do you get internet when you directly connect to the ISP modem?

What kind of internet do you have? 
 

Possibly some kind of MAC address filtering. My ISP assigns IP address based on MAC address of the device connected to the modem. So maybe the ISP enabled that on their network. If the router in question has a MAC address clone feature I’d try that.

I dont really understand the question.. Im sorry, my internet knowledge is limited. But as far as how the ip works, it is automatic

Some ISPs limit the amount of CPE's allowed to be connected to there modems to preserve IP space since its a precious commodity in the ISP world. I would give them a call and ask them to refresh the modem to release any of the data and then plug your router into the modem after and see if you get a connection. If not, then the router itself may be bad since you get a connection when you plug directly in.

Yes, but some ISPs registers a MAC address to your account. That MAC address is the only thing that can get an IP issued. Many ISPs use MAC address’s to control access period. Comcast my ISP requires the MAC address of the modem to be registered to have internet access. Some ISPs go further and require the MAC address attached to the modem to be registered. So it could be that is what’s stopping you.

I tried to connect directly back to the ISP modem and now i dont have connection there aswell.. I guess it is still on bridge mode and waiting for me to plug the asus. How do i revert it you know?
