I have a D-Link wireless router (Di-524) and DSL internet. When I connect my computer with a network cable directly into the ISP modem, downloading pages from the internet is quite fast. But when I put the router in between the modem and the computer, it's quite slow. For example, when there's not router, a page might take 2 seconds to load. With the router, it takes over ten seconds to load. I have tried it with two different computers and many different websites, and it's always the same. It doesn't matter whether the computer is connected to the router wirelessly or with a cable. Either way it's just as slow (both wired and wireless). The router shouldn't be the bottleneck because its bandwidth capabilities are much higher than the ISP.
I went to one of those websites where you can test your internet speed by downloading a large file from the website, and I was surprised that the test showed only a slight decrease in speed using the router. It was only about 10% slower when using the router compared to not using it. But when showing a web page, it seems like pages take 5 to 10 times longer to load when using the router. I think this is because the download test website was doing one big file, and maybe the router doesn't slow it down in that case, but that with a web page there are lots of little files, and maybe there's some sort of standard overhead slowdown with each file.
Do you have any ideas that could help me? Are there settings I should change? Should I get a new router?
thanks in advance, John
