Wifi working but can't connect via cable ??

Question

Hi
I have a cable modem connected via a network cable to a router which then sends a wifi signal. I also have another network cable running from the back of the router to a desktop PC.

The last few weeks, I cant get internet connection (limited or no conectivity) via the network cable, but all laptops with wifi can get internet access.

I tried hooking up a laptop via the network cable from the router and the laptop also does not get internet connection.

I then tried connecting the cable modem directly to the desktop PC skipping the router all together and I get the (limited or no conectivity warnings)

Also did this with a laptop and same outcome.

The network cables are not damaged as I can get signal from the modem to the router and send out a wifi signal which connects to the net. But not via the cable...

Any ideas would be great !!

Answer 1

I believe it's the network settings of the LAN connection. The WiFi connections are using the Wireless LAN Connection settings instead.

Check the TCP/IP settings of the Local Area Connection settings. Go to Control Panel > Network Connections > Local Area Connection. Check the properties of TCP/IP. Make sure that DHCP and DNS is automatic.

If that's ok and still no connection, check the DHCP server and DNS pass-through services in the router for the LAN interface. The WiFi interface seems to be fine, just check the LAN one. However, I don't think this is the problem since you also get limited connectivity even when directly connected.

Main suspect: the Local Area Connection settings on the PC especially DHCP and DNS.

There could be something wrong from the router port to the PC's network card.

If your router has other network ports, try using those to connect to the PC.

Or replace the PC's network card.

Or connect a network adapter to the PC and connect wirelessly.

This is probably a problem that has to do with DHCP.

try this: go to control panel, network connections, right click on local area connection, and click properties.

then, look for "Internet Connection (TCP/IP)" -- you may have to scroll down. click it, and click properties.

click to specify the information in the next lines.

try entering 192.168.1.101 (subnet will auto-fill), and the gateway is 192.168.1.1 IF THIS DOESNT WORK, replace the IP address with 192.168.0.101 and 192.168.0.1

for DNS servers, I personally use 192.168.1.1 (or .0.1 whichever your router uses), and 4.2.2.1 (a reliable dns server)

hope that helps!

in case you're actually not making use of your router (in accordance on your tale), then I propose you utilize a third social gathering utility for cyber web connection sharing. it's going to make your pc A because of the fact the server for pc B. attempt to google any utility for cyber web connection sharing.
