Replaced a tplink 8960 with an 8968( version 2) a month or so back.
I have found I can't get any WiFi devices to show a connection speed other than 72mbps.
It should be able to provide more than that.
Have tested against a sony xperia android tablet,galaxy note 2 and the wife's new HP laptop. 72mbps reported on each device.

Have checked the WiFi is set to nz. I manually set it to use channel 6 after looking at what the neighbors are using.
The frequency options are - "20" or "40" or "Auto" - pretty sure the old 8960 had "20/40" and it did show faster than 72mbps.
I have also set it to use wireless N only - I have no devices that need old protocols.

Seems to make no difference which of the 3 settings I use - its always 72mbps.

Anyone else got one of these? What speeds are you getting?
What WiFi settings do you use in the router?

Sounds like you're only getting  20mhz channel frequency. Try setting it to auto or 40mhz?

Theres some funny dependencies in some routers. Pretty sure I've come across one where it only goes full speed on channel 1.
Another common one is you need to use AES encryption to get .11n mode. But it sounds like you're getting n (72mbps).

There's some other good info in this thread

Yep - have tried 20 have tried 40 and have tried auto settings. Also set it to AES when I changed it wireless N only.
Will try I mucking about with the channels and see if that makes a difference.

I can't say that so far this is exactly a great router. I initially tried changing its default address on my network to a 10.x.x.x address, because that was what I had been using. This caused it to lock up every couple of days. After a factory reset and using the default 192.168.1.1 address at least that is all stable now.

You probably need to turn off TKIP encryption. I had a similar problem on a W8960, and it was driving me nuts for a long time. For some reason if TKIP is enabled the router won't use dual-band so you can't get higher speeds. (So the wifi encryption should be just WPA2/AES, I think.)

I actually had to swap the TD-W8968 that I bought before Xmas.
It was very unstable - I logged a couple of calls with TP-Link and they ended up saying it was faulty and issued an RMA number.
Swapped it yesterday and got a v3 unit - the old one was v2. Apparently the v3 has a different chipset. It has a slightly different menu.
Hopefully this unit is stable.

Havent got too far with checking the wifi speed.
After I googled a bit I found that smaller devices just physically have one antenna/radio, so can effectively only use part of the wifi.
Seems 72mbps is about the max a Sony xperia tablet Z and a galaxy note II can do - its ok I guess.
Will have to test using the wifes laptop - I presume that has a better radio setup in it.

You are correct !

The unit is a dual-chain router.
If the client radio in your laptop or device is only single chain, it will only work at a maximum air speed of 150mbits with a perfect signal.

When you remove the radio overhead - thats the extra data that gets inserted into the stream for error correction etc, then you typically get an actual throughput of 60% of the airspeed. So for 150mbit N the maxmimum you will ever see is about 90mbits with a perfect signal.

When running a 40mhz wide channel in 2.4ghz you will pick up all sorts of interference so unless you are away from any urban or suburban area, i doubt you will ever get that.
