Stuck at 54Mbps

Are you connecting with the same security type settings as you was with the older adapter?

what band are you conneting on? 2.4 or 5?
How far and how many walls are you going thru?

I've tried connecting on both the 2.4GHz and 5GHz bands both yield the same results. As mentioned, the 5GHz band will go upwards of 166Mbs but it won't with this adapter.

For this setup I'm one floor up and a room over. Not a very far distance. I just can't seem to cross the 54Mbs speed with the AC adapter, but the N900 works fine!

I know this is probably not ideal, but can you try connecting with that same system (or at least same adapter / similar setup), in the same room? This way you can see if the adapter and driver is working properly, or maybe it's just a advanced driver setting wrong in the driver properties?

believe there is issues on windows 8 on 5Ghz ( driver related... but there is answered on 5Ghz issues)

I'm limited to connecting at only 54Mbps.

You are using WPA2 encryption?

I'm having this exact same problem...this is really weird, all the issues on this forum, are exactly what I'm encountering with this WiFi Adapter...

When I first connected this Adapter moving on up from the WNDA4100, the speeds dropped from 3.0MBps down/200KBps up to about 2.5MBps down/ 300KBps up....then a few short hours later, my new WiFi adapter, this here A6200, decided that my speeds to drop even more, lol, and now my downloads are at 300KBps from 2.5MBps......HUGE drop, nothing has changed since the moment I plugged it in, maybe just moved it from USB slot to USB slot, but still....nothing at all has been switched in the advanced options or any of the sort....I wonder why the speed decrease and why it's now capped at 50-72mbps.

Also, when I first connected it, and downloaded big files at 2.5MBps, it would disconnect about every 15 minutes....then one time, it finally reconnected and is now stuck at 50-72 Megabits per second.

Any idea why this might have happened?

I'm on Windows 7 x64, by the way.

have you found a solution to this issue? I'm experiencing the exact same thing, stuck at 54Mbps on my R6200/A6300 combo on the 5G side. I have other N devices that connect up to about 104Mbps on the 2.4G side, but that's not why I bought this expensive router combo. I'm not getting any better speeds than I was with my old $50 router. I'm wondering if I have a bad A6300, but it says it's connected using AC mode. Any suggestions?

Did you perform this test yet?
If you are having low singals than try this test.
and get back to us.

I have the same problem but I have windows 7 so it’s not a windows problem. It's either a driver problem or a hardware problem. I plugged the A6200 adapter into my laptop and tested it right near the router and it's still the same speed. Does anyone know how to fix this problem?

I found the solution to at least my problem. For whatever reason the setting under Advanced/Setup/QoS "Enable WMM (Wi-Fi multimedia) settings" was unchecked. Checking this immediately changed the connection speed of my A6200 connected PC from 54Mpbs to 702Mbps. It also increased the speed of every connected wireless device from to ~72Mpbs or greater. I confirmed that it's this setting by disabling it again and saw an immediate drop in all connected wireless device connection speed.
