Your right. Some homes do have metal studs and the reason is as you said. Also it's stronger. Bigger buildings are mostly made out of metal though these days. Also reinforced concrete.

Concrete seems to kill any type of RC signal. I know I cant remote start my car if it's parked in a concrete parking garage.

I work out of a large concrete and steal building and my cell phone signal sucks when I'm inside.

I have stayed in a lot of large hotels that have Wifi throughout the large building that are built on metal structures. Mostly the signal was real good however they probably have boosters or repeaters throughout the building.

Not based in science or deep research or tests. These are just a few of my long term personal experiences.

Hotels use repeaters throughout the buildings generally, as do schools, colleges etc. and other large buildings which require a long range.

Concrete will greatly reduce any type of signal but not as bad as Cotswold stone does (and living close to the Cotswolds there's a lot of that round here which makes installing a wifi network for someone rather difficult).

Metal structures do hinder signals but a partitioned wall with metal studding isn't solid metal throughout the wall, the signal will still get around it. But it wont be metal studding on structural walls. Metal studding, at least this side of the pond is used mainly on budget builds where a lot of internal walls need erecting fast for little money, generally timber is used in most builds.

ON my moms house WIFI seems to be very good,on mine not so great on inside,and on the outside it is so strong i can get 2 miles only because i have 2 WATT amp plus a large antenna

I stayed in a lot of hotels since i travel a lot,and found out most hotls seem to be pretty good at libraries the signal is really bad,i found out burger king has a very good signal,and starbucks

Mostly why i dont like WIFI too much,internet is great ,and using a WIFI printer But for a monitor or video you need a very stable singnal

Good news my board came in so will be testing this week,also looking at making a autoswitch for WIFI and bluetooth,if WIFI is down it switches to bluetooth and when WIFI is up it switches back

I got my other WIFI board in from elechouse ,so will be able to test both boards

I see others are having trouble hooking up to TLG10UA03 ,I will find whyand best solution to fix it and post my data

Other good news since i will be in china and near Shen Zhen, China ,where the elechouse factory is,i can see if i need help from them

can't wait to see your results. WIFI is the only thing holding my from getting my rc robot finished
