DD-WRT firmware is working in WDR4900?

Sorry for doublet post.

Yes I know that.

HiSpeed you know that tp-link is only SOHO devices and you can't compare it with Cisco and other SMB solution. I know that situation is very irritate when your router is stop working but I can't do...

I said openwrt is a medicine ;)

We don't know corporation politics in TP-link. Maybe is something wrong with management. We can only waiting for better firmware solution and speak about this on forum.
