I connect with bridge mode second router with main router, but when I pull(removed) cable from Lan to Lan, don't work wifi but still bridge mode.
I think there is a language barrier here. We need to clarify the terms.
When you say, "When i pull(removed) cable from Lan to Lan" this part doesn't make much sense. I assume you are connecting some computer to the BRIDGE via LAN cable. Of course it's not going to work if you disconnect the LAN cable.
Bridge mode works like this
Gateway <--> Router <--> Router Wifi <--> Bridge Wifi <---> Bridge LAN <--> End client (ie: Computer)
if you want to remain wireless and increase your range, you need a wifi card on your computer and a WIFI Range Extender.
Gateway <--> Router <-->Router Wifi <--> Range Extender Wifi <--> WiFi on computer.
