My cable ISP replaced the Com21 modem by a Surfboard 3001i (and also made changes in his servers), well here the good news: can download from a local FTP at 450/550 KBytes/second means 3600/4400 Kbites/second, and from outisde the country I got a place at Florida that let me downloaded mIRC at 150 KBytes/second = 1200 kbites/second, the bad news are that from other sites the speed sucks and went down to 6 Kbytes/second, and that now my IP is not more fixed, is reassigned every time by the server, I was used to the old one...
They told me they are working in the international connection to improve it an make more stable, just seat and wait...
Time to learn is endless
