And with ISPs supplying higher and higher speeds, WiFi is showing it's limits. On 2.4GHz you used to see 54Mbps tops. And you see this often today if the WiFi client is well, not well matched with the router.
Besides the fact that WiFi is half duplex and shared air space where your Ethernet goes full duplex and does not have to share the air space.
I wish there was a nice article to go over all this but the short story is that we expect WiFi to be slower than wired. Move to 5GHz and keep the distances to about 20 feet for top performance.
Any client that wants wired speed over WiFi will be your most difficult client until they learn how things work.
1. I just went through testing eight wireless routers connected to a D3.1 cable modem. ALL except one restricted LAN (ethernet to laptop) to less than 500. Called tech support of the different companies and it was useless.
2. Is there a simple website which gives optimal settings for each router? Right now I'm using an ASUS RT-3200 and the 2.4 band is low at 40 down, and the LAN out is 300. The cable modem is providing 950 to the WAN.
There's the double rant!!
