I configured my new router and noticed that WiFi connection is way slower than Ethernet connection.
Ethernet connection giving a download speed of ~60Mbps and upload speed of ~30Mbps while the Wifi only giving download speed of ~20Mbps and upload speed of ~15Mbps.
This is a new router with 802.11n and it says it support 300Mbps.
Here are the Wifi settings of the router,is there anything I can change to get higher speed :

Those 15-20 megabit/sec throughputs you're seeing are fine for 802.11g, which is what (unbeknownst to you) you're actually configured to use here.
The IEEE 802.11n spec requires that you do WPA2 (AES-CCMP) or no security, and it requires that you do QoS (WMM). You've blocked yourself from doing 802.11n by doing TKIP-only and disabling WMM.
Also, by setting your channel width the 20MHz only, you've limited your N data rates to 144.4 mbps max. (Don't get me wrong, using 20MHz-wide channels is the right thing to do from a "good neighbor" perspective in the crowded 2.4GHz band. If you wanted to use Bluetooth on a client machine that was also doing 40MHz-wide 802.11n in the 2.4GHz band, it might not work out very well.)
Also note that the rule of thumb for Wi-Fi TCP throughput—on an app that uses TCP in an optimal manner—is 50-60% of the signaling rate. So even if you made the 3 changes I suggested above, and you truly had a good 300mbps N client machine (2 spacial streams in both directions, support for 40MHz channels in 2.4GHz) within good range of the AP, you shouldn't expect to see performance much greater than 150 megabits/sec (about 18 MebiBytes/sec).
By the way, please tell me that these settings (TKIP only, WMM off, 20MHz-only) were not the factory defaults for this product. That would be really sad if they didn't know better and were accidentally effectively disabling their marquee feature by default.
4Change your band from b+g+n to strict N. Otherwise it will be in protective mode and you'll never see the full N / MIMO speed. This requires your clients to be N and support MIMO, but you knew that.
7Using say to verify speed You can generally expect only 50% of the channel speed for DL and less for UL, as it is a half duplex link.
You might try slowing down beacon rate to 1000mS. ensure no P2P services or Apps are running and verify your RSSI levels. Also try auto 20/40MHz
RSSI levels are often shown on some Wifi drivers in -dBm for signal and noise. You can't rely on bars.
With 54Mbps Wifi you need around -70dBm for full speed and -80dBm just to connect. Noise floor is usually -95dBm to -100dBm.
The higher the bit rate, the more bandwidth required for N speeds and the strong the signal must be.
I dont have all the answers and I know how to optimize the G rates, but not the N rates yet.
0If you are using a cabled Lan connection then switch to WIFI.... Yes WIFI will be slower
To correct this first unplug your Lan Cable then go and connect to your wifi. You will see the correct Wifi speed now. BUT NOT WITH LAN PLUGGED IN... OK??
Lan is being seen as a Ethernet connection and wifi will not disable it when you go to WIFI connection. Disconnecting has to be done Physically.
Note here: If you want to do speed tests on all 3 scenarios Do the following: First test your lan connection speed. then exit from and turn off Speedtest program (ACTUALLY DO THIS BETWEEN ALL 3 TESTS) now go and connect to wifi... leaving Lan connected. Make note to compare of all 3 tests here, being fair run 2-3 tests on each scenario, Exit and turn off speed test, now unplug Lan Cable and run speedtest again...
Did this visibly fix your issue? David
Hope this helps you! David
