Only one computer can connect via ethernet, all others have "limited access"

Meant to say TWO computers!
This started about 2 days ago and I have no idea what to do anymore.
Basically, there are 3 Ethernet cables connected to the main router. One cable goes to my dad's laptop, one goes to my stepmothers desktop PC and the final one goes to my room where it plugs into another router (which then connects to a Raspberry Pi, a PS3 and my desktop PC).
NOW this has worked fine for weeks up until recently. Now the only computers to have Internet access is my dads laptop and my stepmothers desktop.
Which leaves me with no connection.
I've tried switching the ports around, tried unplugging everything for over a minute, tried plugging things directly into the modem rather than through my router - basically nothing I do works.
I tried troubleshooting on my PC and I'm told "Ethernet doesn't have a valid IP configuration". So I CMD my way to flush DNS, and doing the "ipconfig /release" thing. This tells me "An error occurred while releasing interface Ethernet : An address has not yet been associated with the network endpoint."
And that's about as much as I know. Help. :(
I'd give that a shot but you forgot to say which menu that is so I don't really know where to look :v:
Network Connections > Adjust adapter settings (left sidebar) > right-click properties on your ethernet controller
Then click on TCP/IPv4 and Properties and you'll get there.
Don't forget to reboot after setting your IP settings. Windows will prompt you, but it means it, reboot.
If this doesn't work, see if you can connect to the router in your room. Make sure the two routers are plugged in nicely.
If you haven't done so already, do this:
Unplug the [I]power[/I] from the modem and both routers, and shut down your computer.
Plug in the modem and wait 3 minutes.
Plug in the power to the first router and wait 5 minutes.
Plug in the power to the second router and turn on your computer.
From there, try the net. If it doesn't work, open up a command prompt, and type this command:
tracert 8.8.8.8
This will attempt to trace a route to Google's DNS server. The first two hops [I]should[/I] be your internal routers before going out your ISP. If the net's not working, the traceroute will fail, but where it fails will depend on what's broken. (Probably won't work at all, I predict.)
None of those solutions worked, tried both just now. Still no Internet.
I did the trace though and it gave me "Transmit error: code 1231" if that means anything :/
Try
ipconfig /renew

ipconfig /renew[/QUOTE]
It sits there for about a minute and then tells me
"An error occurred while renewing interface Ethernet : unable to contact your DHCP server. Request has timed out."

[QUOTE=~Kiwi~v2;46470747]by a long shot
disable ipv6
it will be under the same area

above post too[/QUOTE]
Nope. No result.
What happens if you plug your computer directly into the cable that is currently jammed into the ass of the second-stage router? Make sure you either reboot your computer after plugging it into the cable, or open up a command prompt and type:
ipconfig /release
ipconfig /renew
I suspect the problem lies between the two routers.

Same thing. Doesn't matter if it's plugged through the second stage router or directly into the first router. I get the same ipconfig errors.
Not sure why updating network drivers would help since this is a problem that just showed up out of nowhere despite working fine for weeks before :v: as for that I wouldn't know what drivers to look for or where.

Also this issue is for ALL devices I plug into the router. PS3 as well won't connect. So updating PC stuff would likely be fruitless.
That's gonna be a problem since I don't have a spare modem or router...
And I'm home sick so can't go out and buy one.
Dammit.
Check if your router does have DHCP server built-in by either reading manual or by going to router's configuration page.
Have you tried doing a factory reset on your devices? Wouldn't make sense why it would happen out of the blue, but who knows.
do you have DHCP enabled on both routers?
Good news!
First of all: I don't have a router. Like, no routers. My mistake. What we have here is an ATA-box provided by our ISP, which plug into a switch. From there it went to dads laptop, stepmothers desktop, and another SWITCH in my room. So my mistake there. Also explains why I could never enter router settings.
SECONDLY: I called my ISP! Here's the really good news!
Turns out they stopped giving out more than 2 IPs per household! That's right, they downgraded from the previous 6 IPs per household to just 2. Which meant that the two computers that were connected at the time (all my devices were shut off during the switch) got to keep their connections while I was left in the dark.
They told me I go out and buy a proper router, which WILL generate more IPs. Which is a good idea anyway since I have an SVN server I can't manage properly without fiddling with ports, which is something I can't do with a switch.
So yeah, turns out it was my ISP all along! Fuck T3! :D
That explains fucking everything.
