Curious which model Linksys/Cisco Router that is? Reason I ask is, I just purchased a e4200V2 Linksys. DOCSIS 3. Boosted my speeds considerably. Range? Will need to determine but seems good at the ranges used. Only had it a week.
That is a 4200. I found my problem though...In the settings for the two transmitters I had power setting on “auto” for the main transmitter. My networking professional neighbor changed the setting to 40hz permanently. It made a huge difference...
