Sorry, didn't really get the real reason you wanted to remove DIR-615 but introducing a switch in the equation. rizvanp has shown how to make the network bridge .. which I believe doing almost exactly as what you did above with no extra cost. I haven't got any problem with this setup .. but I wish I can remove the DIR-615 totally but not replacing it with another device ..

Ooops, my mistake, may be miss you out earlier...
Now I'm maintaining & update the list on Excel already! 
Actually when I saw Riz's suggestion on the RB250GS, I did call & ask Landasan even before I bite the bullet to buy from Soliton.
I also explained the potential to them before as our Riz is very confident that it will work, but somehow it seem to me that they are not really interested....
even my recent call to them again and said "it is CONFIRMED" that this unit can work very well with UniFi, still tak-mau la.....

Yes, I'm also hoping you guys can get the unit around RM140, if really so unlucky we kenal custom, then have to even & share out later....

Ok, now can someone suggest what kind of "unclear yet not attract tax kind of description we should write on the shipping invoice?
How about the value, is SGD20/unit reasonable?

Soliton already emailed the format, we just have to write anything we want so they just follow typing, please suggest/comment guys!
