Internet speed may be affected by many factors. This FAQ will help you figure out what cause the problem and offer you some tips to improve the speed.
Note:
End-device mentioned below means computer, laptop, mobile phone, etc.
Case 1 Wired and wireless speeds are both slow
Step 1. Login the web-based interface of the modem. Check DSL Status. Please take screenshot of the Status page for further help.
Step 2. Connect only one end-device to the TP-Link modem via cable, and do the Speedtest® (www.speedtese.net) three times without doing any high bandwidth activities like P2P download. Take screenshots as well.
Step 3. Check wired link speed of the end-device and take Screenshots. Please refer to this FAQ.
Skip this step if you don’t know where to find it.
Step 4. Contact TP-Link support with screenshots of Status page, Speedtest® results and link speed info, and let us know the total bandwidth from your ISP.
Case 2 Wireless is slow, while wired speed is normal
Step 1. Simplify network topology by connecting one end-device to the TP-Link modem via wireless, and do the Speedtest®(www.speedtest.net)three times without doing any high bandwidth activities like P2P download. Take screenshots.
Step 2. Check wireless link speed of your end-device and take Screenshots. Please refer to this FAQ.
Skip this step if you don’t know where to find it.
Step 3. Change Channel Width, 2.4GHz→40MHz, 5GHz→80Mhz, refer to this FAQ.
Go to step 4 if still to no avail.
Step 4
The problem occurs on 5GHz or 2.4GHz? If end-devices support 5GHz as well, connect to 5GHz to check if it’s better or not.
For 2.4GHz, change the Channel (channels 1, 6 and 11 are generally best, but any channel can be used, please try a few more channels). A wireless channel determines which operating frequency will be in use. It is not necessary to change the channel unless you’re noticing interference problems with nearby wireless networks.
If the above suggestions still cannot fix the problem, pleasecontact support with screenshots of Speedtest® results and link speed info, and let us know the total bandwidth from your ISP.
