Note:

1.This Article Applies to: TL-WR841N , TL-WR842N , TL-WR743ND more All broadband access products which are low-speed of Speedtest. 

2.This article is not relevant to you if you have any of the following condition: Your Speedtest tool comes with the device itself.

 

Preparations:

Please connect a computer to TP-Link router by cable and connect a laptop/PC/phone to TP-Link router by wireless connection.

It’s recommended to close all applications on the accompanying client that occupy network resources other than the Speedtest tool.

APP inSSIDer and Network analysis, the tools used for network quality assessment reference, must be installed in advance

Restore the router to factory setting. 

 

Step I.  Identify environmental factors.

1. Troubleshoot the placement of the router’s antenna relative to the receiver

The correct placement, your accompanying device should be positioned as high as the router’s antenna and aligned.

Note: Do not place your router on the ground during testing because it will affect wireless performance.

The wrong placement:

  1. Antenna polarization direction is inconsistent;
  2. The accompanying device is too close to the router;
  3. The accompanying device is not aligned with the router's antenna
  4. The height of the accompanying equipment is inconsistent with that of the router's antenna

2. Identify the source of interference in the test environment:

Method 1: Open the insider tool which is installed in your accompanying device in advance.

Check the number of nearby interference sources from the marked bold red box.

Method 2: WDS scan function, you can check the interference when you click the ‘scan’ button.

Step II.  Comparison test.

1.Your accompanying device should be in the same position and height as the test router and the competing router.

2.You must use the same accompanying device to connect to each router and test alternately.

3.When testing alternately, all router wireless parameters should be consistent.

The configuration of the wireless parameters is shown below:

Wireless

Mode

Channel

Bandwidth

RTS Threshold

2.4GHz

802.11b/g/n mixed

1

HT40

2347

5GHz

802.11a/n/ac mixed

Band 1

HT80

2347

4.Output the configuration profile: conf.bin

5.Record data for the entire comparison test process

6. Follow these steps to get the network card information,

Path: Control panel -> network and Internet -> network connection

Double-click the wireless card and select properties

Then we can check the information of the network card and the negotiating speed.

From this table, you can compare your accompanying device with standard specification:

1.Compare wireless and wired clients

Step III.  Configuration of the router management interface

Configure WAN interface

1.Ensure the Quality of Service function is unable

2.Ensure the Bandwidth function is unable

3.Ensure the NAT function is enable and the MTU value is default setting

Log in the router management website -> Select Network option -> Click the Internet option and Edit -> Enter the Advanced setting

4.Link mode of Wan interface

ADSL/VDSL can be distinguished from this data table

ADSL (Max Rate Upstream<2Mbps Downstream<25Mbps)

2.4GHz Wireless configuration

 

1.Open the inSSIDer from your accompanying device and you can collect the information from the tool:

Channel: 10

Negotiating speed: 65Mbps

RSSI: -85dBm

The associated BSSID: 00:11:22:33:44:55

2.Package capture

Set the parameters as following:

RTS Threshold:2347 When there is less interference

Short GI: Enable

WMM: Enable

TxBF: Enable

MU-MIMO: Unable (This function can be turned on when multiple clients are present)

Turn on Sniffer and grab packets on the appropriate channel;

Record the Beacon Frame and Probe Response package;

2.How to increase the current wireless rate?

Select channels with little interference and record the interference and signal intensity of different channels by using inSSIDer;

Bandwidth selection: HT20 is selected when the interference is strong, and HT40 is selected when the interference is weak.

 

5GHz Wireless configuration

1.Open the inSSIDer from your accompanying device and you can collect the information from the tool:

Channel: 10

Negotiating speed: 135Mbps

RSSI: -85dBm

The associated BSSID: 00:11:22:33:44:55

2.Wireless package capture

Set the parameters as following:

RTS Threshold:2347 (When there is less interference)

Short GI: Enable

WMM: Enable

TxBF: Enable

MU-MIMO: Unable (This function can be turned on when multiple clients are present)

Turn on Sniffer and grab packets on the appropriate channel;

Record the Beacon Frame and Probe Response package;

3.How to increase the current wireless rate?

Select channels with little interference and record the interference and signal intensity of different channels by using inSSIDer;

Bandwidth selection: HT80 is available
