Hi there,

I bought a TP-Link Archer TX3000e PCIe wifi / bluetooth card recently. I've installed it in my Windows 11 machine and updated to the latest drivers, but am getting very slow speeds.

I have an Orbi Pro mesh wifi network and other machines can achieve ~250Mbps, which is pretty much my advertised speed from my ISP, but this card is only capable of a tenth of that, getting 20-25Mbps. 

I'm currently on the latest Intel v22.180.0.4 driver but have tried the drivers on the TP-Link site too, none of which have made any difference. I've tried a different PCIe slot, no change. Tried moving the aerial around, no change.

I've tried various settings, none of which have made any difference - I'm currently forcing the card to the 5GHz band (802.11ac), which gives me a network link speed of 650/650Mbps, but even with that I still only get ~20Mbps.

Any suggestions before I send the card back as faulty?

Thanks
