Windows 7: DIR 615 reports link at 300Mbps, windows reports 150Mbps

DIR 615 reports link at 300Mbps, windows reports 150Mbps

Hello there,
Recently setup my home wifi network, i had been noticing that my link speed to any device through my Dlink DIR 615 router, was always 65Mbps (as reported by the device), i searched around that i should set the channel width to 'auto 20/40mhz' to gain speed; however now that i did that, the link speed increased but only to 150Mbps as seen in the screenshot attached.

I could live with it but when i check the router's wireless status page, it reports the link to be 300'M' (which hopefully stands for Mbps) as it should be, sometimes its at 270M as well, but it always reports double of what windows and other devices like my android phone report...
i'm having a hard time figuring out whats going on with my setup.. i've checked for interference but there are hardly any other wifi networks in range.

Some more misc info about my setup: I use a Dlink Nano N300 adapter with my desktop...which was recommended for use with the router. Using WPA2-AES PSK, running the router in WPA2 only, wireless N only mode...Generally receiving full bars throughout my home.

Why is there a conflict in the link speed info displayed on my devices and the router?

Thanks

Some more details, i installed the crappy dlink software to obtain more information about it and surely got soemthing out of it.
In the attached screenshot, its written Tx/Rx:150Mbps/300Mbps...which basically means its transmitting at 150M, hence what it shows in Windows, which leads me to the question, why?

Hello,

You might want to verify if you have the latest firmware of your router.

Have you tried changing the Wireless Mode from N to Mixed and see if it changes anything?

The firmware seems to be the latest available from what i can see via google... and yes i tried the mixed modes but still the same behavior.

I suspect from this thread Are there any HIGHLY rated wireless N routers for under $50? - Wireless Networking | DSLReports Forums (Page 5) that these tx/rx values are probably very normal...

I have also found this Thread with a similar issue as yours, not unless you may still RMA your DLink router and perhaps try a Netgear or a diff brand. Reading reviews helps a lot too.

I would assume you have tried changing the Security from WPA2 to WPA or WPA to WPA2?

Is your wireless adapter capable of 300 Mbps?

The box does say N300... it is strange though how they've never clearly stated its theoretical speeds.
EDIT:
i think i just solved it, but its just a wild guess, the router reports the adapter's signal strength at around 50%, now since the link speeds very much depend on the signal%, the adapter's speed to the router is degraded.

I've contacted their support...not very hopeful though.
