Contacted support and got the answer, can only handle one channel. So I would have to go and switch when I wanted to use my other wifi pc/s.. Not the end of the world

How do I actually talk to a human in customer support? I have tried calling and it basically just tells you to go online ;-( I have emailed and receiced a answer a few days later but again really did not answer my question below. Basically all I was told that using there RE355 would half my speeds and if I hooked connected yet another RE355 to my existing one it would have that yet again. So I was told to sync both to my Uverse WIF router but did not answer about what would happen to my speeds??

I have my Re355 setup and working, what I'm trying to do is get a stronger signal through the house (hopefully 5ghz),

My main question is if I did buy another RE355 and set it up the exact same way as my original one I have working already would I be able to get a stronger WIFI signal?

From my working RE355 I have been running att speed tests and can onlg get a DL speed of around 3 to 6 MBPS which is pretty pokey.

The distance in the house between the Uverse Router/Re355 is under 35' max , I believe the biggest issue is that its a older home with wood lath and plaster walls and radiator heet.
