Your suggestion about pinging with different sized packets showed me that I couldn't ping with more than 512 bytes. I set the mtu to 512 and can now send and receive e-mail, surf and even use ktorrent. But there are still problems: 1 - the internet is VERY slow 2 - Although I can work, none of the other machines on my network (Linux or Windows) can do anything on the Internet. I seem to remember that a few yearss ago, there was a thread about what the optimum mtu is to allow other machines on the network to function. My original mtu of 1452 was based on that thread, if I remember correctly. I assume that changing it to 512 is what's preventing the rest of the network from functioning. 3 - There is obvoiusly still a problem here and I don't know if it's Bezeq or 015-Smile. I'm convinced the problem is not on my machine, since as I wrote earlier, I have the same problem on my regular Mandriva partition and a clean, non-updated Mandriva partition.
