Both my TP-link wireless card (TL-WN881ND) and TP-link wireless adapter (Archer T9UH) are unable to detect my 2.4 GHz wifi. I have tried all the steps on https://www.tp-link.com/au/support/faq/2253/ however both still don't discover my network. Both are working as they can discover other networks such as my neighbours. I have also disabled Mac Filtering, QoS schedualling and access control on my router. Anything else I can try to make my 2.4Ghz network discoverable to my tp-link devices?

Thanks in advance :)
