Hi,

Please connect to the Sky Max Pod with the internal Wi-Fi card of your laptop and then get us the "Security type" and "Network channel" from the "Properties" screen of that Wi-Fi connection. (make sure the laptop is indeed connected to the 5 GHz of the Sky Max Pod, and not the Sky Router)

Hi

Pictured below is how it looks when my Laptop is connected to the Sky Max Pod with my Internal Adapter:

And below is how it looks connected to the Sky Max Pod using the TX50UH:

I note with the TX50UH it's connecting with WiFi 4?

From the first picture we can tell that the laptop has connected to the Sky Max Pod via channel 157.

TP-Link's USB Wi-Fi adapters based on Realtek chips that are specifically made for the "EU" regulations and will block the use of channels 149 and above.

Please look for a white serial number sticker on your TX50UH (if there is none, then you need to get the retail box the product came in and look at its serial number sticker) and see if it states something like "EU/1.0".
If it indeed were to state "EU" (and not something like "US" or perhaps "UK"), then that would explain the behavior.
 

By the way, the 5 GHz band that comprises channel 157 can only provide a channel width of 80 MHz. Given that limitation, the "600 Mbps" you get with the internal Wi-Fi card of your laptop is quite good. If you wanted to get significantly more speed (either with the internal Intel AX201 or the TX50UH), then you would need to utilize another 5 GHz band that allows a channel width of 160 MHz, provided that the Sky Max Pod actually supports 160 MHz channel width. (I couldn't find detailed specs for the Sky Max Pod)

The sticker says EU1.0.

Guess I'll just box it up and return it then.
