Wifi connected but no internet only with one device

Friday - last edited Friday

Tags: #Network Connectivity

Model: TL-WR841N

Hardware Version: V14

Firmware Version: 0.9.1 4.17 v01e4.0 Build 200911 Rel.65868n

Hello support, please your help with this issue.

I am having trouble connecting to the Wi-Fi network. It looks to be connected normally to the Wifi, but there is

no internet connection. The strange thing is that this only happens with one laptop. Another laptop and several

cell phones are able to connect to the TP-Link router´s internet signal without any problems.

I don't know if it's a compatibility issue between the laptop's Wi-Fi network adapter hardware and the router,

because the same laptop connects to the internet on other Wi-Fi networks.

The connection is:

ISP provider cable modem --> TP Link router (with Ethernet cable) --> Laptop

The laptop connects to the internet via the cable modem's Wi-Fi signal, but it does not connect to the internet via the TP Link router's Wi-Fi.

The same laptop connects to the internet via the mobile hotspot Wi-Fi of several mobile phones. The problem is only with the TP Link router.

I tried changing the wireless security type from WPA2-PSK with AES encryption to WPA-PSK with automatic encryption, but it didn't work.

I´ve tried to update firmware but it seems is the latest what is installed.

What else can I do to solve or identify the problem? Is there any kind of trace or what do you recommend?

Thank you in advance.

The link for your region as you posted is https://www.tp-link.com/cac/support/download/tl-wr841n/#Firmware

If you follow this link you'll see the FW relase: TL-WR841N(US)_V14_180319

The US in parenthesis shows the FW region, which in your case is US.

You could check that by yorself looking at the botom sticket of your router - details (Case 1):

What's happening here is most probably that you're jumping several versions ahead in one try.

Try the following - update first to an intermediate version like TL-WR841N(US)_V14_210203 to see how it goes.

Upon successful attempt, you can continue upgrading the FW version further.

Hi, thanks again for your support. Still receiving the same error during firmware upgrade with the last version you shared.

Seeing physically, my router´s region is ES. See image below.

Well, if it's with a (ES) firmware after all, you can try this FW release here. If that doesn't work either, I would recommend contacting your local support for further assistance.

For maximum security of your local network, use the following wireless security settings:

Forget the SSID on your laptop and re-connect again with your password.

This time it works the firmware upgrade. That was the correct version, sadly only the same laptop cannot connect to

internet, I did forget and re connect again and connects to WiFi but without access to Internet. Is weird.

Thanks so much for all your help and time.

Lets be sure that you're not using any Access Control or Parental Controls feature:

Open command prompt on yur laptop and issue the following command (cmd):

ipconfig

Then post the screenshot for this command outuit for the wireless adapter here. It should be something like this:

Which brand and model is your laptop wireless adapter ?
