Try this beta firmware.  We have had some reports that from customers who have speed issues with fiber providers.  http://support.tp-link.com/f/d418f2fa74/?dl=1.   For 2.4GHz however the maximum through put for internet in an ideal enviroment is about 150Mbps but since an ideal enviroment does not exist the average speed you will see on 2.4 is around where you are at currenty 60-80 Mbps.   

Also please check wired speeds and use the built in speed test to show the speeds to a wired device and dirrectly to the router.  

Thank you

To answer the 1st question why do we advertize 1000 Mbps when at best it will only get 150 Mbps?  This is because what we advertize and actually what the industry advertizes is not Internet speed but tranfer rates on the internal network.  1000 Mbps is the maximum theroretical transfer rate you could see between devices on the network on the 2.4 GHz band.  However the 2.4GHz technology due to various items such as technolog limitations, saturation, congestion and interference is limited to at best 150 Mbps but as i said typcially a 2.4GHz network will deliver around 60-80 Mbps is most network enviroments. 

For the 2nd part the speed test results between the router itself and to a device connected to it.  

Speed test to the router:  Not sure what your upload speed is but the routers speed test is coming in at right about where we would imagine it would be for a 1Gbps service.  

Speed test from wired computer.  We would first want to check the port link rate to ensure its not set lower than it should be.  you can also check the link rate of the wireless connection as well.  These need to read at 1 Gbps at least in order to meet the higher threshold of speed.  

Search:  Control Panel, choose Network and internet > Network and Sharing Center > Change Adapter Settings > Double click on active adapter > look at speed.  

If the speed rate is below 1 Gbps then the speed you see for your test results will also be lower.  Several factors can affect the speed as well such as:  Hardware limitations on the client device, the ethernet cable type, applications running on the PC for wireless distance and obsticles are also a factor.  And yes, the router could be a factor as well.  It seems though that the router is getting the speed the issue seems to be either on the client devices or the connection to the client devices.  I would recommend loading the frimware provided in my previous post to see if that corrects the speed issues on your client devices.  If not check the aformentions items and let us know.
