| [Help Me] Wifi not getting ISP max speed...works for lan-wifi tr I am using a D-Link DIR-815 Wireless N 300 Dual Band Wireless Router.
I am using a Dell laptop for some testing. It supports the 2.4/5ghz dual band.
When using 5ghz right next to the router I get the full 30-35 Mbit connection(speedtest.net) which is what I pay for through the ISP(Charter). The issue is that even right next to the router I can't get the full data transfer at 2.4ghz, it is approximately 20Mbit. I was intrigued and assumed that interference from other devices in my apartment building were causing interference and droping the speed of my wireless connection below that of my ISP.
I decided to buy Lan Speed Test, and Lan Speed Test Server. This tests the network speed between two pcs by transferring data from PC1 RAM to PC2 RAM and measuring the time. I ecpected this test would yield the same result and be limited to 20MBit. I was surprised to find that transferring from wired PC1 to wireless PC2 I was getting results of 40Mbit ul /40Mbit dl.
So, my question is how can my wireless signal be capable of transferring 40Mbit up/down to a lan PC but I cannot get the full 30Mbit through the ISP.
Also, before anyone asks why I care since I am getting full speed on 5ghz, the 5ghz only works in very close proximity to the router. I am trying to get higher speeds out of the 2.4ghz band for a PC located farther away from the router.
Cheers

| Re: [Help Me] Wifi not getting ISP max speed...works for lan-wif No, Wireless file xfer speeds are different from the wireless connection speeds and xfer speeds can not attain the same. At most you'll ever see from a upload on Single mode N at 5Ghz is about 8-10Mb. This is was I see when sending something to my wired Server on a Gb connection using the Single mode N on 5Ghz from my Mac.
There are many factors that contribute to wireless performance, HW support, SW, connections and external interferences. Any testing with a router should be done wired for test purposes as WiFi can't provide stable results due to these fluctuation. This is the nature of WiFi. 5Ghz is best in line of sight with out any walls, floors and material between device and router. 2.4Ghz doesn't have this issue as much. |

| Bimmer,
I do not think you understood what I am saying. The wireless connection speed is max 300Mbit....probably connected at something less "say" 100Mbit. I have tested and confirmed file transfer speed to a wired pc from wireless laptop to be 40Mbit+ from what I assume to be "loss". However I cannot get speedtest.net to yield a test higher than 20Mbit. It should be capable to go to 30MBit as it appears both my wireless connection, and ISP are capable of 30Mbit.
The ISP connection has been tested multiple times through wired internet and is always above 30Mbit. |

What wireless modes are you using? Try single mode N if you have this option and your devices support it.
If your not getting the initial 300Mb connect between your device and the router, then need to set for single mode N. There is information regarding 300Mb connections on the D-Link forum site.
Using mixed modes and mixed cipher will not allow this connection to be made. Need to set cipher to AES only and back to auto 20/40 I believe. Need to check to see if your devices support N mode and any 5Ghz frequencies.
See how it goes. |
