So.
I have a ZyXEL-p660hn as my deafult router. I flashed dd-wrt on a tp-link wr841n. I set it up according to this tutorial: http://youtu.be/N4x3QRaBnS4
Everything went ok, my network worked... for a few seconds. I can access the internet from the 2nd router for a few seconds after connecting, but then it doesn't load anything, even though both my phone and my laptop say that I do have internet connection... I have local access, because I can see shared files on the network of the main router from the 2nd router, so it's only the internet connection that stops working after a few seconds..
I know it seems like a mainstream problem but I haven't found anything about it :/
Any ideas?
Oh, the only thing I didn't do according to the tutorial is that I couldn't set repeater bridge cause there was no such thing.. So I set client bridge.
Meanwhile I tried using my phone's hotspot as the primary router and.. It worked just fine. Something must be wrong with the original primary router..
