I have a dual-boot win7/Ubuntu machine. No issues browsing in firefox in Win7. But after upgrading from 11.04 to 11.10, browsing in Ubuntu is awful. There is a long pause before anything happens (DNS lookup?) and then the download speed itself seems slow. Based on reading other posts, I made these changes in the network settings:
IPV4: Automatic (DHCP)
Can someone walk me through a trouble-shoot of this? I didn't have problems in 11.04, so I'm perplexed about how something got more broken in the new release.
