Home Network help please

post #1 of 10
Thread Starter 
I'm not sure where to post this but I need help.

My internet stopped working. I have 2 computers wired and 1 wireless laptop. From the cable modem to laptop I can get internet to my laptop wired, from the router to laptop I can get internet. 1 computer is in a room, no internet, I try plugging in my laptop there and I can get internet, same with the other computer too. So the laptop seems to work for some reason, but I can't get my desktops to work. I even tried connecting an old desktop pc and that couldn't receive internet. I tested all my cables and they all work. Atm I have a cable modem to an 8 port switch. Before I had cable modem to a 4 port router, a cable from that router to a wireless router that had 4 ports too. I couldn't get internet working from either of the 4 port routers wired to the laptop. I'm very confused why the laptop receives internet but I can't get my desktops to. I've been trying to figure this out for 8 hours now!

Help me please!

Thank you

I'm not much of a networking expert, but I do have 2 questions:

Why did you have it connected like this: cable modem > 4-port non-wireless router > 4-port wireless router? All you you need is the wireless router because it has 4 ports which means two of those ports can provide a wired connection to the two desktops and a wireless connection to the laptop.

So my second question is this: can you eliminate the non-wireless 4-port router and only use the wireless router (as an experiment)? So here's what I am talking about:

Cable modem > 4-port wireless router > computers.

So I'm saying that all you would have is the cable modem, an ethernet cable cable, the 4-port wireless router, 2 ethernet cables, and a wireless signal (and nothing else). Try it.
It's a computer!

I had it configured like that because in the past I had more computers connected and just left it that way, and it all worked fine for years.

I tried cable modem to 4 port wireless router and can't get internet through that for some reason now, the wireless signal still shows up and I can connect to that, but it won't have any internet.

I can do cable modem to the 4 port router and get internt in all locations wired, but only with the laptop, desktops won't connect for some reason.

Did you unplug everything to reset the connection? Mine sometimes gets jammed up when it has been on for a long time. And also what Cables said just go modem > wireless router > computers.

Yeah I unplugged everything for 10 min+ because usually when this happens that fixes it. Before when everything was working I had the Cable modem> 4 port router> then a cable from the 4 port router to a 4 port wireless router. Now I have it Cable modem> 8 port switch and can get internet everywhere wired, but only on my laptop. I have no idea why my desktops won't connect.

Try downloading the most recent LAN driver for your systems onto a USB drive from the laptop. Uninstall LAN drivers from desktop - install fresh drivers. Just a shot in the dark. I had my desktop lose all connectivity after an update and this worked for me.

well from the quote above... i can tell you, you won't get more than one connection via the switch cuz it has no routing capabilities...

go cable modem -> 4 port wireless router WAN port
log into your wireless router and check to see if DHCP is enabled for the switch ports

check to see if your desktops NIC adapters are set for DHCP

I did what you said, it was already enabled, but I tried a few other things and it is now working as of now.

Thanks a lot everyone for the help
