I'm having a new (to me), strange networking problem on an FC5 install on a new computer. Basically, I can't make some network connections to some sites. The best way to explain this is probably with some examples: 1) I can ssh to my own server. 2) I can http to my own server, but I can't download the image on my home page (a very small png). Nor can I get the squirrelmail home page to load from that server. 3) I can login via IMAP to my own server, but then Thunderbird times out when downloading mail. 4) I can login via POP3 to my ISP email account, but then Thunderbird times out when downloading mail. 5) I can get to any google web site, like my gmail, and to register.co.uk via http, but I can't download slashdot pages or New York Times pages or most other web pages (timeout on "Waiting for /server/"). In all the cases of failure, it's not DNS--I get the address fine. On the same computer I have a Windows XP install, where all these things work fine. So I know it's not hardware. For what it's worth, everything worked fine for a about a day and a half before I lost some networking. I'm clueless as to what might have changed since it worked. The network adapter is an SiS 190, which is historically problematic in Linux, but I thought it was all supposed to be worked out in FC5. System-config-network calls it a "Silicon Integrated Systems [SiS] Unknown Device 0190," though, which doesn't sound good. I have seen links to an SiS-provided driver for the 190 that I can compile and install (eg http://www.cse.iitb.ac.in/~mohitz/tech/lan.php) but they look old (kernel 2.6.9 era). Is there some easier/more current way to get it working on FC5? I checked this list for help, and I don't see any complaints about this adapter since FC3 ... Thanks, Matt
