Agree'd, it was literally as simple as you describe with my old DIR-301, but unfortunately not with the DIR-615 D2

No, they cannot be adjusted beyond design parameters.

The interface may allow you to enter arbitrary numbers beyond design parameters but the chip will not obey it. In the case of the DIR-615 the default transmit power is 18dBm and the maximum it will ever go to nomatter what you try to set is 20dBm.

I thought antennas only affect the gain and therefore impact the signal
Signal != amplifier output power

There are some DIY option to direct the signal.

Yes, ERP (or EiRP) is relevant for path loss calculations but irrelevant for determining if you are going to overheat the router. That's what they were suggesting would happen from fitting bigger antennas...

An omnidirectional aerial in an ideal world has a circular radiation pattern when viewed from directly above.
When viewed from the side, it's a circular lobe shape.
A 2dBi 1/4 wave dipole may be circular lobe shaped from the side but not a 16dBi.

A 12dBi looks like the attachment below.

A 16dBi like the OP is talking about (if it really is, because that is a ludicrous claim) would be even more flattened.

Learn to read. That's what he's already doing.

None of the DIR-615's have the ability to screw off and on antennas.

Who really cares as it is obvious you cannot read or you would not have missed my answer to Thenry and as for the D Link again who cares buy another that can be altered, try getting your own life.

I can read perfectly fine, that's why I did post moronic nonsense to begin with.

We were having a perfectly decent conversation in this thread that had nothing to do with you until you came along and derailed it with irrelevant horseshit like you always do. And you tell me to get my own life? As always, you first.

the manual says they are. obviously this is wrong for some versions but all of them?

No need to post anything moronic as you are one oddly enough, the proof is in the way you have to cyberstalk other posters truly a sad person.

Do also check out the rather helpful manual which is a fault on D Link's side maybe you could also stalk them.

You just like to try Yan king my chain but always fail.

You could also post here about it as well D Link Forum or even to D Link as it clearly states HERE removable but a stalker dislikes facts as it gets in the way of their perception of reality.

Which are range tested results and all turn to pants once inside someone's house.

I guess we'll just see how it turns out. Worst case is that it doesn't work and I won't be any worse off since the router only cost be £5.30 and best case is that I'll have better performance! =)

Btw has anyone heard of the router company called H3C?

which product of theirs are you looking at?

None in particular, I just saw one of their routers today and it looked pretty impressive, it had 6 antennas, 3 for 2.4GHz and 3 for 5GHz. I've tried to find information about it but can't find anything (don't have the model number as it was mounted on a wall).
