Wifi internet works, but my cable internet isn't working?
Question: I'm at a university campus to start off. Now, my wifi is working perfectly. I'm currently using my school's wifi to do all my internet stuff for the moment. However, initially, I were using my ethernet cable for internet. For the last 3 months, my cable internet were working just fine. But this afternoon, my internet suddenly stopped and I thought my school's internet was down. But after checking with my roommate and a neighbor, both of whom are using the ethernet cable and have fine connection, I figures that maybe I needed to restart my PC. But even after a restart and troubleshooting my internet connection using Windows, I still cannot get an internet connection with my cable. My wifi's fine, which is a little weird. From my network center screen, I seems to be able to connect to my school's cable network, but the line between that network and the internet is "x-ed" out. That's odd, considering my roommate's ethernet cable connection is just fine. Also, after doing a troubleshooting, I found the error of that my "Local Area Network does not have a valid IP configuration"? Hm, I have an address starting 169.254 but no IP address under the Gateway, DNS, and WINS server. Is that abnormal, or is that normal given my cable connection isn't working? Resolved for now, thanks for the infos all. My ethernet connection went back to normal, don't know why or how, but I'm not complaining really.

A "169.254" IP means that your computer asked for a DHCP server but no one replied back to you. So your system created an IP address to allow you to limp along. This means there's a problem somewhere along the path between your Ethernet adapter, the Ethernet cable, the switch your cable plugs into, and the router the switch plugs into. A quick test would be to take your computer (and your Ethernet cable) over to your roommate's Ethernet jack and plug your computer and cable into his jack. If your computer gets a proper IP address then you know your computer is fine and that the problem is on the college's side. However, if you get another 169.254 IP -- try using your roommate's Ethernet cable to connect your computer to his jack. If you get a proper IP at this point, this proves your Ethernet cable is bad and you need to get a new Ethernet cable to get back in service. For extra points, your roommate can plug his computer into your Ethernet jack. His computer should get a 196.254 if our theory about a bad network segment is correct. Then contact your school's IT dept and ask them to fix your Ethernet issue while you go Wi-Fi.
Are you using XP? I would make sure that the Windows Firewall is not blocking the web browser connections. 1. Click Start, and then click Control Panel. 2. From the Control Panel, click Security Center. 3. If Windows Firewall shows On, you are protected. 4. From the Security Center, click Windows Firewall. 5. On the Exceptions tab, check mark Internet Explorer and Mozilla Firefox. Click OK to close out windows. Test your access. If you do not see the two programs listed on the list then: 5.On the Exceptions tab, click Add Program. 6.In the Add a Program dialog box, click Browse and search for Internet Explorer and Firefox. If they are not there then you have to add them by their directory location. Click "Browse" and type "C:\Program Files\Mozilla Firefox\firefox.exe" and save. Repeate for Internet Explorer "C:\Program Files\Internet Explorer\IEXPLORE.EXE" (paste them without the quotations). Good luck!
I am experiencing very slow internet speed. The problem is not with the internet service or cable but with....
I have a Netgear Rangemax WiFi router which keeps dropping both cabled and WiFi PC's off the internet. Ideas?
This is a network fault. Usually because a gateway router is not connecting you to the internet. You may have to bring this up with your campus IT dept. In the mean time chech a few things in the Network and Sharing center. Make sure that you have a proper IP adress. Usually it starts with 192.168. Check that you have DHCP turned on (get address automaticly). The easy way to do this would be to compare the settings on one of your friends computer to the settings on yours.
a service is not starting. either set it for automatic and start it, or repair windows. what wifi? the wifi adapter in your PC, or are you talking about the router? be specific. ipconfig isn't going to do anything useful if the network services aren't started to enable it. networking drivers reinstall might help too, that's much easier than a windows repair.
It appears like your local wired network adapter has incorrect configuration or is befuddled. Make sure it is set to obtain IP address automatically (network connections, right click on wired network interface, select properties, select IPv4 connections in pop up, click on properties - ). If this does not return configuration, power down pc for at least 2 minutes and restart. If it continues to act up you may have a faulty network interface or a faulty patch cable or a faulty wall port; a little detective work on your part should determine where it is.
