I could really use your help as I am almost about to give it all up and toss my computers throughout the window along with the router.
I have this problem with extremely slow transfer rate when downloading files (from any server) and several websites are loading really slow.
I'm connected using ADSL at 2.5Mbps. I have 2 PCs in my home network. Both my computers have Windows XP SP3 installed and are connected using Ethernet cables (RJ-45). I'm using the Siemens SL2-141 router.
Up until a week ago everything was going just fine. I was able to download files quickly and the transfer rate was about 225KB to 300KB (also in P2P software).
Now, every file I download is about 40KB or in much worst cases 12KB.
In my country, there are only 2 infrastructure companies available: One works via ADSL and the other through cables.
I got connected with the internal server of my infrastructure and did a speed test. The result was excellent - downloaded a file at 300KB.
Realizing there's nothing wrong with my infrastructure, I called up my ISP and after several checks, nothing was wrong on their end.
The ISP tried to connect with my username and password and said the speed is as it should be (on their end, of course).
I scanned both my computers for viruses and found a Trojan, but I think I got it removed.
I really don't know what I should do next.... I mean, if I can download at full speed when connected to the infrastructure, how come I can't download at full speed when I'm connected to my ISP? I turned off and unplugged one of the PCs just to make sure there's no use of any bandwidth. I also closed any process and application. I've tried ping and got some packet loss. Also used Netstat to see online connections - nothing was suspicious. I've tried NETSH on one computer and even that didn't help. Tried hard-reset to the router and still...
I'm considering formatting the computer, but I don't think that would work... I mean, the problem exists on both computers... Both of them are experiencing slow transfer rate.
