I'm attempting to cascade two routers to extend my wireless network, using a Linksys E1200 as a master and a Linksys E1500 as a slave. The E1200 is running the stock firmware but the E1500 is running DD-WRT.
I have read this: http://www.tomshardware.com/forum/33700-42-ultimate-modem-router-setup-thread and I followed the first option to the letter and failed. I am able to achieve only limited connectivity. I also read this: http://www.wikihow.com/Cascade-Routers and tried both options and failed both times.
Now, I have done a 30/30/30 on the slave router, so it's gone back to the default DD-WRT settings. The master I'd like to leave be if at all possible. Can someone give me a step-by-step guide to cascading these two routers or explain why this setup will not work?
