Hello Team,

Have bought AC1300 Archer T4U(US) V3.20, Installed drivers adapter got detected connected with router after entering the password but adapter is showing no internet access(Limited access), Changed the IPV(4) from automatic IP/DNS setting to manual one but issue still persist , can you let me know how to fix this or is it my adapter issues. I have connected my desktop with my router via Ethernet cable and there are no issues in internet access so is all other devices via WiFi, only the adapter is not able to access internet. have tried ipconfig release, renew and dnsflush also but no use

@AC1300

Thank you for posting on the TP-Link Community.

Can you please kindly verify what is the system version of the Windows computer, is it Windows 7? What is the driver version for this T4U adapter, please check it as this:

Are you connecting to the 5G network or 2.4G? It is also suggested modifying the wireless settings on the router, such as changing the wireless channel and channel width, you may run a Wi-Fi analyzer to verify which are the clearest channels, choose that one; change the channel width to 40MHz for the 5G (20MHz for 2.4G), then reboot both the router and computer to give a shot.

BTW, here is the latest public driver, you may also uninstall the previous driver you have installed on the computer, then reinstall this driver manually:

Here is the guide to install the driver manually on the Windows 7:
