I have four computers in myhouse. One is connected by wire through a wireless router (D-link DI-614+) to my ADSL modem; the other three are connected wirelessly. Two of the computers are communicating perfectly and receiving web pages at great knots.
The remaining wireless-connected computer can get onto the ABC (Australian Braodcasting Commission) site at great speed I can click on the latest news, etc. so it is downloading current material; not stored material. It can also get onto at least one other Australian site with ease.
However, if I try to get onto Google or Yahoo seems to half load and then stop.
I have encountered difficulties with loading particular sites using a computer connected directly to an ADSL modem. These difficulties were fixed by altering the packet size to the maximum that could be sent with 0% loss plus 28. That worked well (using the advice from DSLREPORTS.COM).
However, that does not work with the wireless connected computers. Or it does not seem to. With the prolem computer I can ping any sites I want to and adjust the packet size in the CMD window. I get good returns with 0% loss. However, setting the packet size plus 28 does not seem to affect things. Nothing seems to affect it.
The only solution my ISP could offer was to go into connections in Internet Explorer, click on LAN, and blank out the automatically detect settings box. Actually that slowed things down.
Note: although this computer is wirelessly connected it is only 1.5 metres from the wireless router.
I am running Windows XP on it without the service pack 2.
The PC wireless card is a D-ling DWL-G520+
The ASDL modem is a Dynalink RTA 300.
It has 0.5 mB of RAM and a 30 mB hard disk; these are probably not relevant.
