I installed Ubuntu alongside windows 7 and I have a feeling something went wrong with the installation. The OS works fine for the most part but I have no network connectivity and cannot pull up any URLs. I am able to connect to my home Wi-Fi network but I have no network access. I ran through the basic TS guide and still no results. Anytime an application needs to communicate with the network I get various error messages or time-outs.


Should I reinstall?
How do I uninstall and reinstall Ubuntu?

Can you add a few more details? E.g. which network cards are installed. (Feel free to boot windows 7 and copy that information from the device manager). Are those devices detected when you boot (search in dmesg). -- Additionally, what do you mean with "I am able to connect to my home Wi-Fi network but I have no network access"? Is your wireless card detected but does WPA2 negotiation fail? If so, what error messages? -- As to "should I reinstall: Probably not, but no harm done. ""How do I reinstall?" Just boot from the CD/pendrive and redo the installation on the save partitions. –  Hennes Apr 6 '13 at 0:00
I don't have the name of the network card at this time, but it was detected when I ran the network troubleshooting CMD line. To clarify, I can connect to the home wi-fi network and WPA2 authentication does not fail but any attempts I make to connect to the internet thereafter fail. I receive a cannot connect to server error from Firefox and when I try to ping the gateway it times out. Example: browser will not load any web pages and when I try to search for updates that fails as well. This still may not make sense but I appreciate the assistance. –  Zerominimus Apr 6 '13 at 0:13
If you can not reach the gateway then yes, updates and anything using a remote network will fail. The question is now to determine why you can not reach it. Can you add the routing tables to the original post? –  Hennes Apr 6 '13 at 0:18
I'll add the routing tables later this evening. Hopefully that can provide some insight. Is it possible for ubuntu to detect the network adapter but not have the appropriate driver installed to run it correctly? –  Zerominimus Apr 6 '13 at 0:20
Yes. It can detect hardware even if it has no driver for it ("detect", not "make use off"). On older kernels you can see this during boot or in dmesg. Those devices will have a (no driver attached) part. On Linux you can also see all hardware with lspci (On BSD's use pciconf). –  Hennes Apr 6 '13 at 0:29
