I know it is a pretty lame question, but I am not a pro in networking, so I will still ask it. And I will try to explain details where possible.
I want to create the following setup:
Phone line is in the hallway downstairs. I connect unit A to the phone line. Unit A is a combined ADSL modem + WiFi router + 4-port ethernet switch. (correct me if I am not using the terms correctly). The model is D-Link 3680.
Note: I know the modem functions correctly and connects to the Internet (I have tested it). I also know that DHCP in the router functions correctly and I can connect to the internet with my laptop.
I disable WiFi in unit A and run cable (in fact a PowerLine link) upstairs to the third floor.
Note: I have checked that I can connect to the internet on the the other side of the link. I still get address from DHCP of my router and everything is fine
What I want to do now, is instead of connecting to the cable on the third floor, hook up another router that I have. Unit B: Huawei HG533: a combined ADSL modem + WiFi router + 4-port ethernet switch with USB port for Storage Devices. I want to have wifi enabled on it and I want to connect to the internet through it. Obviously I disable modem functionality in this device and just connect the ethernet cable to the uplink.
The problem is, that I cannot connect to the internet once connected to the Unit B. And I cannot ping unit A.
So, could anyone sketch a correct network topology for this setup? What settings do I have to look at? Where do I even start. Which one of two units (or both) need(s) to run DHCP server? Do they have to be on the same subnet? How do I setup default gateways.
[Internet] | [Phone Line] | | |--------------| |---------------| | Unit A | | Unit B | |---------------| | ADSL modem |---[powerline]---| ADSL disabled |--[WiFi]--| Laptop(s) | | | | DHCP? | |---------------| |--------------| |---------------| | | [USB] | |---------------| | HDD | |---------------|
Oh, and if anyone is interested in why am i doing it. It is simple: Reason 1: I don't want to have my WiFi Router downstairs because signal is weak on the third floor. Reason 2: I use USB port and connect my 1Tb hdd to it and I don't want to leave it in the hallway, because I live in the flatshare with people I don't really know. Reason 3: I want to have WiFi within my room, not just an ethernet cable.
Sorry for being such a n00b, any advice will be appreciated.
Oh, and I have read this thread, but does not provide enough explanation.
UPDATE: in response to CharlieRB's comment, here is a picture of the Unit B:
