I'm just trying to understand if this is normal. The card on the right is rated at 300 Mbps as per the manufacturer's specs and is showing 292 Mbps which is close enough. Its rated at 300 Mbps as per the manufacturer's specs but only showing 72.2 Mbps. I've included a pic to let you see what I'm looking at. You may get it to negotiate a faster speed but now you likely have interference from a neighbor so the real life thoughput may be slower. You could try to go into your router and force it to use 40mhz channels.

Since it did not negotiate this it means ether router or pc nic does not have 2 or more antenna or the signal is not good enough to get it to work.I suspect your router does not support 300m.or this is the dual band lie of 150m+150m The 300m requires 2 overlapping data streams. Still even if it could get 40mhz it will still only connect at 150m. I am unsure what 292 means but 72.2 means the pc is getting good signal but it has detected a signal on a adjacent channel so it has moved to 20mhz from 40mhz. These represent the negotiated rates between the pc and the router. Those number are what is called a MCS index.you can look up the tables. Not sure if this is right but here is a photo of what I'm talking about: I also swapped the black and white wires on the card and it still shows up as 72.2. Even swapped out the card with another Atheros card. I've updated the drivers, deleted the drivers, reinstalled the drivers. I restored to factory default of Windows 8. THINGS I'VE TRIED: I'm running Windows 10. One TP-Link card, rated at 300 Mbps, shows 292 Mbps. Two Atheros cards, both rated at 300 Mbps, both show 72.2 Mbps.

The Atheros has a download speed of about 1 Mbps and the TP-Link was around 17 Mbps. Speed testing both confirms that I am losing Mbps. QUESTION: So why am I losing Mbps on the Atheros but not the TP-Link? They are both rated at 300 Mbps but the atheros only shows up as 72.2 Mbps. Its rated at 300 Mbps and it shows up in the wireless status as 292 Mbps. So I bought a new TP-Link USB wireless adapter. As luck would have it, I had a spare atheros card and popped that in. But in the wireless status it only shows 72.2 Mbps. The atheros wireless network card that came with it is rated at 300 Mbps. PROBLEM: I bought a new ASUS laptop model X551MA. Sorry if this has been asked and answered but I could not find anything that fit my problem.
