ATT 4290 Wifi Extender Two?
I own a AT&T 4290 wifi extender that I bought several years ago. I'm thinking of buying another on Ebay. Can I run two simultaneously? If so can they be connected together with ethernet (like backhaul) or just wifi?
I'm at a loss on how strong this thing still runs. I'm getting +/-300 Mps upload and download with this extender connected in another room about 40+ feet away via wifi.
