No Connection via Wan Resulting in loss of LAN R7000p

Hello!

 

Today my ISP got some issuse with the internet. I have comfirmed it with them. Wihtout an ISP my router can not be logged into on any of my wired devices, only way to log into the router is by using the WIFI 5G.

 

My question is why does the router stop acting as a DHCP to the wired devices?    

My experience with my old routers would be if the ISP hade issuse with the internet i would still be able to use the LAN function on the router.

 

I hope i am just not aware of some simple changes in the settings in the setup of the router otherwise i will be disapointed on the router.

 

Thanks in advance

Well two things hit me immediately. Your IPCONFIG data is quite odd...

 

IPv4 address for one, 169.254.2.210 and NO Gateway IP Address.

 

Look at THIS. From it:

 

=========

Computers use addresses starting with "169.254." when they do not have a manually configured address 
or when they are not told which address to use by a service on the network.
They are commonly called the "link local" addresses.

Routers are not allowed to forward packets sent from an IPv4 "link local" address, so they are always used by a directly
connected device.

========

 

That means you manually set these up and are not using DHCP. Also it looks like you are using the wired part of the router as a switch. You probably have 2 different networks, one the wired one and then the wireless which is driven by the DHCP of the router.

Hello!

Thanks for the reply.

 

Okey my router is configured as a DHCP. But i got a second router in the house that is configured as an AP. I tried to unplugg all wired devices from the router even the WAN port. Got the same autoconfigured ipv 4 adress, i tried to disable the network unit on my computer and after a restart on the computer i got a normal Ip adress. Put back the wired devices and the same thing happend again. Some autoconfigured ipv4 adress. So i tried everything again and after the restart i got a normal ip adress (nothing plugged in the router except my computer).  Tried to plugg in only the WAN and bang the ISP is back up again so i plugged in all the other wired devices and everything works. I am starting to suspect something else then the ISP problem.

 

Well i cannot search more because its working now, but please reply if you think you know something that can help me if this happens again.

 

Thanks

What is this second device?

 

Did you "configure as an AP" according to its mode settings, or have you just tweaked various things in it?

 

 

Just another user.
