I have had the following problems and wondered if anyone knew a fix...or the problem. We have a d-link 2640b adsl router/modem installed and recently our speeds became really slow. I thought someone maybe hacking the wireless and so reboot the modem and reinstalled everything. We have 1 computer connected to it via ethernet and the other by wireless. The speeds however are still very slow, even with the wireless pc turned off. I have gone to speedtest.net and results are poor. Interestingly, if I plug in the old usb modem supplied by the ISP, the speeds are fine, I get the usual 3.8mbps The problem seems to be speeds through the router. or the hardware between the router and the PC??? However, the wireless computer also has slow speeds. I have tried to run malware scanners, turned off and on firewalls and antivirus...but still seem to be having the slow speed problem when using the router. The supplied modem by tiscali on both pc's when used, gives very good speeds any help is appreciated!
