Hi @gozlertsde 

May I know what operation mode of router you are using? If you want to set TL-WR902AC so that your wired clients and wireless clients can get the network at the same time, please select range extender mode for TL-WR902AC:

In addition, could you please send a screenshot of the relevant error message (red circle ×) here?  It will help us locate the problem.

Hello! Thanks for the reply!

I think I probably didn't explain my situation very well, or, I made a mistake!

The wifi source, is my own (let's call it hotspotA), but, I am using the share hotspot mode to create an entirely new wireless network, let's say hotspotB. As I use one for work, and one for personal. Thus, I am intentionally not using the extender mode

I will factory reset if need be, but I would like to solve it in case it were to happen again.

Here's a screenshot (and, as noted, internet via ethernet has no issues):
 

Thanks!

Hi  @gozlertsde 

Sorry for late reply. Because you didn't include my account number when you replied to me, I didn't receive your message in time.

It seems that you want to use hotspot mode( also call 'WISP mode'), you can see the link below to select the right mode for your need:How to choose right mode

If you want to set it to different mode, it is better that you can reset the device:

Go to System Tools > Factory Defaults. Click Restore to reset all settings to the default values.

If there is any update, feel free to report it here.

Apologies! But no worries, I am not in a rush! : )

Oh, yes, I am using the WISP mode, so it comes back to my original question as to why mobile device do not receive internet, but connect okay to the hotspot.

Maybe I do require a factory reset after all (I have powered off and on the router, and all other network parts, to no avail); as maybe it is too complicated a fix! (thinking_emoi)

I can't think of anything else to add at this point.

Thanks kindly!
