More speed/bandwidth from an 802.11n laptop<-->WiFi Router/Modem connection?
kyrathaba:
By the way, congrats Ian on achieving 150 Mbps... :)
kyrathaba:
Here I am sitting at my usual desktop PC within five feet of my router... Meh!
Carol Haynes:
Try changing the wireless channel at the router - it may be a conflict with another local network.

Well, I might not have got there, or so quickly, at least, without the comments/suggestions in this discussion. As above, the helpful comments by @Carol Haynes and @4wd got me thinking.
What I have been able to prove so far is that you can get full performance to spec out of this type of wifi kit - so it's an achievable potential performance spec, and not just theoretical (as @rgdot had suggested might be the case) - and the kit works very well, given the suitable operational parameters and environment.
It also suggests that this (and probably most similar) wifi kit is likely to be out in the field, operating at well below the potential performance spec, due to incorrect operational parameters - never mind the environment.

...I'd be tempted to try a cheap 802.11n USB adapter in the laptop, (to eliminate the Draft-n component).
FWIW, I've used this, this and this, (all of which are Realtek 8188/8192 chipsets), to connect a WDTV Live to my ASUS RT-N16 over 12-15m through two plasterboard walls, a 50cm CRT TV, a couch and a CD rack, they all connect at 150Mb/s.
After searching a bit, it seems to me that "802.11n Lite n" just means it's 150Mb/s as opposed to 300Mb/s - 600Mb/s, (ie. it's still full 802.11n compliant, just that because it's single antenna it's speed is limited).

- it got me thinking that a cheap USB network adapter from the same TP-Link manufacturer, designed for 802.11n @ 150Mbps might be all that I would probably need to enable me to test what he and @Carol Haynes had been suggesting.
So for approx US$17 and the time of some intermittent fiddling about and firmware/driver installs, I not only have discovered and learned some new things, but also have managed to get the Laptop<-->TP-Link wifi ADSL2+ router working perfectly.
Though tempted, I have also been able to avoid expending the time/cost/effort of swapping the router for another router as suggested by @40hz - kept the focus on the kit being used.
It just goes to confirm/remind that, if you aren't fully conversant with the technology being used, then it helps to be careful and methodical about analysing, defining and treating the causal problem rather than start trying to randomly fix it.
Having got it all working perfectly, my next step is to play about with the beercan reflector and add a 2nd can's height to the existing single-can reflector, because the first can did seem to make a perceptible difference in reducing the variability of the signal speed/quality (strength). I would like to see whether it is possible to get up to 150Mbps at the location 2 rooms away from the wifi router.

Yeah, could be why my speeds aren't better. I've got multiple computers. The laptops have their own internal WIFI "radio" (of whatever brand, who can say), and the four laptops each have a USB wi-fi adapter of different brand, than the router, although they're all "b/g/n compliant" LOL!
For my family's relatively conservative needs (web browsing, checking email), 30-60 Mbps as an average range is acceptable. I'm not knowledgeable enough to go mucking about with things. If it ain't broke, don't fix it (unless you're adventurous, well-informed, and can afford the frustration and cost of failure). In my case, I'd have multiple irritated kids and a wife all irritated if I screwed up their internet connection by messing with something that "works".
