@Tony THanks. I'll try the thether. I tried what you mentioned. Both 2.4 and 5 were lighting up. I named them differently. But no connection at all for 2.4ghz. Will keep you posted.

Need halp. Bought the TP-LINK RE450 range extender and followed the set up instructions. I paired it with my old LinkSys E3000 (CISCO). Installed successfully but only 5GHZ is working. Bought it...
