Wifi is weaker using Gargoyle?

Hello! I finally got DD-WRT to give up the router and hand it to Gargoyle (web-page firmware upgrade didn't upgrade, said it did, but was still dd-wrt, so I used TFTP with success), but now my wifi is weaker!

I have a WNDR3700v2-NA, on the 2nd floor of the house, in the center of the house. I used gargoyle_1.5.0-ar71xx-wndr3700v2-squashfs-factory-NA.img, which I'm pretty sure is the latest version for the North America version.

When I was on DD-WRT, I used to be able to get wifi at about -70db out in the shed, quite far away from the router. It was very reliable, I could stream videos over the network to my laptop while I had a smoke in the shed.

Now that I'm on Gargoyle, the wifi signal reaches -80db when I'm halfway to the shed, and is totally unreachable in the shed. In DD-WRT, I had the transmit power set to 30db (although I'm aware there's a hardware limit, its what I set it to anyway) on a 20mhz channel width using WPA2, but it worked fine on the DD-WRT default of 20db. Gargoyle won't let me go above 27db, which doesn't reach the shed. If I enter in 20db into gargoyle, it doesn't even reach the basement! Why are they different than DD-WRT?

I have tried 20mhz, 40mhz up, 40mhz down, and every channel setting. I cannot seem to get the signal strength anywhere near where it was in DD-WRT. I have checked everywhere in the house, and all rooms are getting 10-15db less signal than they were in DD-WRT.

Since they are both using the same hardware, and the same wifi settings, and the same transmit power, shouldn't they have the same signal strength on the other end (all other atmospheric conditions being equal)? Obviously signal strength varies due to EMI and such, but this is a large, consistent drop in signal strength, everywhere, at all times.

Also, DD-WRT allowed me to limit the wifi to G+N. But in Gargoyle my only options appear to be G+N+B, or N+A, or G+B, or B. Is there any way to set it to G+N? This is the only difference between the DD-WRT setup and the Gargoyle setup.

Apparently it was because of a set of DVDs that someone had put in the chest of drawers the router was sitting on. The DVDs had so much metal foil in them that they were weakening my WIFI signal.

Sorry about that folks, the wifi works just fine on Gargoyle!
