I am having problems with a Toshiba Satellite Pro 460CDT and a Cirrus Logic 56K modem running on a stock Red Hat 6.1 installation and PCMCIA tools v3.1.2. The modem is detected fine, but when a PPP connection is initialized it works fine for about 5 to 10 minutes and then PPP freezes. Pppd is still running, but no traffic emerges when a ping or traceroute or any other kind of network connection is attempted. Netstat also hangs when pppd freezes. This freezing happens when a lot of network activity happens i.e., an HTTP or FTP connection.
Other people have reported a similar problem on the mailing list, but no-one appears to have a solution - any help or information that people could give me would be much appreciated!
Thanks in advance,
