Hello all - this is just a feedback message, all is working, all is well.
So I have a Linksys WRT54G with DD-WRT v24-sp2 as my main router and I wanted to extend the network (wireles bridge/repeater) with a TP-LINK TL-WR741ND v1.9.
I installed DD-WRT on it thinking it would be a peace of cake but soon found out this wasnt the case. I spent all day yesterday only to find out that the routers were using different chips (broadcom - atheros) and that it may not even work. Today I found this site by mistake and tried installing it on my WR741ND (gargoyle_1.5.8-ar71xx-generic-tl-wr741nd-v1-squashfs-factory.bin) . I set up the bridge and voila - it works.
I just wanted to share this with anyone using similar routers and searching for help.
