Here's a rule of thumb: Just by doubling the distance between router and client you can expect throughput to shrink to one-third of its original value. First of all, the distance between your router and the wireless adapter is a more relevant factor than you might think.

Unfortunately, the laws of physics sometimes stand in the way of proper wireless bandwidth and signal strength (where can I file a complaint?). You may want to turn it off and go "100%" all the time. Also, do check if your router sports some sort of "Automatic" transmission setting. If you value bandwidth over minimal power savings, check out the router's setting and look for entries called "Transmission Power" or various Eco modes. Bandwidth was reduced from an already low 19Mbps down to 5Mbps with my clients and router being only separated by a single concrete wall. Although my trusty Linksys WRT610N router wasn't set up with unnecessary power savings in mind, I turned on its low power modes just to see the effects: The "low" setting lowered the power output of my 802.11n router from 19 to 18 watts. Unfortunately, this commendable approach reduced bandwidth disproportionately. Some routers are set up with their "Power savings" mode on by default. If you're sick of slow Wi-Fi speeds but hate to go back to Ethernet, we've got a handful of tips that'll help boost weak signals.
#Ethernet status as 100mps but only 1 1080p#
50+ Mbps: Enough for 1080p movies and over-the-air backups.
#Ethernet status as 100mps but only 1 720p#
Even though, the typical bitrate of a 720p iTunes TV show is 2-6Mbps, your router needs to compensate for dropouts, other connected clients and prebuffering. 20+ Mbps: This is the minimum you need to even consider HD streaming.

5- The laptop previously was stuck at 100 until I removed smartbyte and then it was blazing fast. 4- The same cable connected via USB adapter is hitting 800 MBps. 3- WiFi on the Inspiron (from the same source) is in excess of 300 MBps.
