home router, wirelss speed is too slow
New to the forum with a question in mind. I have a very basic wireless router at home (DLink DIR601, 150Mbps max). What I am seeing is that the wireless speed is slower than what it should. The bandwidth from my ISP is 8M. When I ran speedtest with wired connection, I can get between 7-8M. But most of the time when I use wireless, it can only get 1.5 to 2.5M. I have been messing with the setup for the router (WEP or not, autoscan the channel or not, which channel to use). I didn't set up any filter, pretty much the factory default at this time. The strange thing is that once in a while, my wireless speed can get to 7 to 8M (same as the wired one) after i changed and saved the router configuration, but I just cannot find what exactly made it happen. At one time, I though using fix channel will do the trick, but it does not. I just wonder anybody has heard or seen such issue (not necessary for Dlink) and what things I can try. Thanks much.
